I know this comes up from time to time, but how soon until we split into more subreddits? Discussion is a bit of firehose lately, and has changed drastically from its earlier role as a place to clean up your post and get it ready for main. We get all kinds of meetup stuff, philosophical issues, and so forth which mostly lack relevance to me. Not knocking the topics (they are valuable to the people they serve) but it isn't helpful for me.

Mostly I am interested in scientific/technological stuff, especially if it is fairly speculative and in need of advocacy. Cryonics, satellite-based computing, cryptocurrency, open source software. Assessing probability and/or optimal development paths with statistics and clean epistemology is great, but I'm not super enthused about probability theory or philosophy for its own sake.

Simply having more threads in the techno-transhumanist category could increase the level of fun for me. But there also needs to be more of a space for long-term discussions. Initial reactions often aren't as useful as considered reactions a few days later. When they get bumped off the list in only a few days, that makes it harder to come back with considered responses, and it makes for fewer considered counter-responses. Ultimately the discussion is shallower as a result.

Also, the recent comments bar on the right is less immediately useful because you have to click to the Recent Comments page and scroll back to see anything more than a few hours in the past.

I guess instead of complaining publicly, it would be better to send a private message to a person who can do something about it, preferably with a specific suggestion, and a link to a discussion which proves that many people want it.

Long-term threads separately seems to be a very popular idea... there were even some polls in the past to prove it.

MIRI's strategy for 2013 involves more strongly focusing on math research, which I think is probably the right move, even though it leaves them with less use for me. (Math isn't my weakest suit, but not my strongest, either.)

Do we know any evolutionary reason why hypnosis is a thing?

My current understanding of how hypnosis works is:

  • The overwhelming majority of our actions happen automatically, unconsciously, in response to triggers. Those can be external stimuli, or internal stimuli at the end of a trigger-response chain started by an external stimulus. Stimulus-response mapping are learnt through reinforcement. Examples: walking somewhere without thinking about your route (and sometimes arriving and noticing you intended to go someplace else), unthinkingly drinking from a cup in front of you. (Finding and exploiting those triggers is incredibly useful if you have executive function issues.)

  • In the waking state, responses are sometimes vetted consciously. This causes awareness of intent to act. Example: those studies where you can predict when someone will press a button before they can.

  • This "free won't" isn't very reliable. In particular, there's very little you can do about imagery ("Don't think of a purple elephant"). Examples: advertising, priming effects, conformity.

  • Conscious processes can't multitask much, so by focusing attention elsewhere, stimuli cause responses more reliably and less consciously. See any study on cognitive

As far as I can tell, it's more of a spandrel than anything. As a general rule, anything you can do with "hypnosis", you can do without. Depending on what you're doing with it, it can be more of a feature or more of a bug that comes inherent to the architecture. I could probably give a better answer if you explained exactly what you mean by "hypnosis", since no one can agree on a definition.
4Paul Crowley11y
Dennett makes a good case for the word "spandrel" not really meaning much in "Darwin's Dangerous Idea".

The Linear Interpolation Fallacy: that if a lot of something is very bad, a little of it must be a little bad.

Most common in politics, where people describe the unpleasantness of Somalia or North Korea when arguing for more or less government regulation as if it had some kind of relevance. Silliest is when people try to argue over which of the two is worse. Establishing the silliness of this is easy. Somalia beats assimilation by the borg, so government power is bad. North Korea beats the Infinite Layers of the Abyss, so government power is good. Surely no universal principle of government can be changed by which contrived example I pick.

And, with a little thought, it seems clear that there is some intermediate amount of goverment that supports the most eudaemonia. Figuring out what that amount is and which side of it any given goverment lies on are important and hard questions. But looking at the extremes doesn't tell us anything about them.

(Treating "government power" as a scalar can be another fallacy, but I'll leave that for another post.)

3Viliam_Bur11y
More nasty details: An amount of government which supports the most eudaemonia in the short term, may not be the best in the long term. For example, it could create a situation where the government can expand easily and has natural incentives to expand. Also, the specific amount of government may depend significantly on the technological level of society; inventions like internet or home-made pandemic viruses can change it.
3[anonymous]11y
I think the "non-scalar" point is a much more important take-away. Generalizing: "Many concepts which people describe in linear terms are not actually linear, especially when those concepts involve any degree of complexity."

I've seen that applied to all kinds of things, ranging from vitamines to sentences starting with “However”, to name the first two that spring to mind.

What is the smartest group/cluster/sect/activity/clade/clan that is mostly composed of women? Related to the other thread on how to get more women into rationality besides HPMOR.

Ashkenazi dancing groups? Veterinarian College students? Linguistics students? Lilly Allen admirers?

No seriously, name guesses of really smart groups, identity labels etc... that you are nearly certain have more women than men.

Academic psychologists are mostly female. That would seem to be a pretty good target audience for LW. There are a few other academic areas that are mostly female now, but keep in mind that many academic fields are still mostly male even though most new undergraduates are female in the area.

There are lists online of academic specialty by average GRE scores. Averaging the verbal and quantitative scores, and then determining which majority-female discipline has the highest average would probably get you close to your answer.

1A1987dM11y
Well, keep in mind that 75% of LWers are under 31 anyway, so it's the sex ratio among the younger cohorts you mainly care about, not the sex ratio overall.
2knb11y
But it isn't the undergrads you're looking for if you want the "smartest mostly female group." Undergrads are less bright on average than advanced degree holders due to various selection effects.
5diegocaleiro11y
I think we are aiming for "females who can become rationalists" which means that expected smarts are more valuable then real smarts, in particular if the real ones were obtained through decades (implying the person will then be less flexible, since older).

Bryn Mawr has gone downhill a lot since the top female students got the chance to go to Harvard, Yale, etc. instead of here. Bryn Mawr does have a cognitive bias course (for undergraduates) but the quality of the students is not that high. Of course, Bryn Mawr does excellently at the only-women part, and might do well overall once we take into account that constraint.

nurses are smart, but not impressively so.

How much difference can nootropics make to one's studying performance / habits? The problems are with motivation (the impulse to learn useful stuff winning out over the impulse to waste your time) and concentration (not losing interest / closing the book as soon as the first equation appears -- or, to be more clear, as soon as I anticipate a difficult task laying ahead). There are no other factors (to my knowledge) that have a negative impact on my studying habits.

Or, to put it differently: if a defective motivational system is the only thing standing between me and success, can I turn into an uber-nerd that studies 10 h/day by popping the right pills?

EDIT: Never messed with my neurochemistry before. Not depressed, not hyperactive... not ruling out some ADD though. My sleep "schedule" is messed up beyond belief; in truth, I don't think I've even tried to sleep like a normal person since childhood. Externally imposed schedules always result in chronic sleep deprivation; I habitually push myself to stay awake till a later hour than I had gone to sleep at the previous night (/morning/afternoon) -- all of this meaning, I don't trust myself to further mess with my sleeping habits. Of what I've read so far, selegiline seems closest to the effects I'm looking for, but then again all I know about nootropics I've learned in the past 6 hours. I can't guarantee I can find most substances in my country.

... Bad or insufficient sleep can cause catastrophic levels of akrasia. Fix that, then if you still have trouble, consider other options. Results should be apparent in days, so it is not a very hard experiment to carry out - set alarms on your phone or something for when to go to bed, and make your bedroom actually dark (this causes deeper sleep) you should get more done overall because you will waste less of your waking hours.

-1Dahlen11y
You're right about that, but the problem with lack of motivation persists even during times when I can set my own schedule and get as much sleep as I need. (Well, to put it precisely, not sleeping enough guarantees that I won't get anything done out of my own choice, but sleeping enough doesn't guarantee that I will, not even closely.)
4Qiaochu_Yuan11y
I agree with ThrustVectoring that you'll probably get more mileage out of implementing something like a GTD system (or at least that doing this will be cheaper and seems like it would complement any additional mileage you get out of nootropics). There are lots of easy behavioral / motivational hacks you can use before you start messing with your neurochemistry, e.g. rewarding your inner pigeon. I've had some success recently with Beeminding my Pomodoros. It forces me to maintain a minimal level of work per unit time (e.g. recently I was at the MIRI workshop, and even though ordinarily I would have been able to justify not doing anything else during that week I still spent 25 minutes every day working on problem sets for grad school classes) which I'm about to increase.
7Dahlen11y
Tried. Failed. Everything that requires me, in my current state, to police myself, fails miserably. It's like my guardian demon keeps whispering in my ear, "hey... who's to stop me from breaking the same rules that I have set for myself?" -- cue yet another day wasted. Eat candy every time I clear an item off my to-do list? Eat candy even when I don't! Pomodoros? Y-yeah, let's stop this timer now, shall we -- I've just got this sudden imperious urge to play a certain videogame, 10 minutes into my Pomodoro session... Schedule says "do 7 physics problems"? Strike that, write underneath "browse 4chan for 7 hours"! ... I don't know, I'm just hopeless. Not just lazy, but... meta-lazy too? Sometimes I worry that I was born with exactly the wrong kind of brain for succeeding (in my weird definition of the word); like utter lack of conscientiousness is embedded inextricably into the very tissues of my brain. That's why nootropics are kind of a last resort for me.

I could have easily written this exact same post two years ago. I used to be incredibly akratic. For example, at one point in high school I concluded that I was simply incapable of doing any schoolwork at home. I started a sort of anti-system where I would do all the homework and studying I could during my free period the day it was due, and simply not do the rest. This was my "solution" to procrastination.

Starting in January, however, I made a very conscious effort to combat akrasia in my life. I made slow, frustrating progress until about a week and a half ago where something "clicked" and now I spend probably 80% of my free time working on personal projects (and enjoying it). I know, I know, this could very easily be a temporary peak, but I have very high hopes for continuing to improve.

Please do go on; I'd be very much interested in what you have to say.
8gothgirl42066611y
Okay. To be honest, it's really hard to say exactly what lead to my change in willpower/productivity. Now that I actually try to write down concrete things I do that I didn't do two months ago, it's hard, and my probability that my recent success is a fluke has gone up a little. I feel like what happened is that after reading a few self-help books and thinking a lot about the problem, I ended up completely changing the way I think about working in a difficult-to-describe way. It's kind of like how when I first found LessWrong, read through all the sequences, and did some musings on my own, I completely changed the way I form beliefs. Now I say to myself stuff like "How would the world look differently if x were true?" and "Of all the people who believe x will happen to them, how many are correct?", even without consciously thinking about it. Perhaps more importantly, I also stopped thinking certain thoughts, like "all the evidence might point to x, but it's morally right to believe y, so I believe y", etc. Similarly, now, I now have a bunch of mental habits related to getting myself to work harder and snap out of pessimistic mindstates, but since I wasn't handed them all in one nicely arranged body of information like I was with LessWrong, and had to instead draw from this source and that source and make my own inferences, I find it really hard to think in concrete terms about my new mental habits. Writing down these habits and making them explicit is one of my goals, and if I end up doing that, I'll probably post it somewhere here. But until then, what I can do is point you in the direction of what I read, and outline a few of what I think are the biggest things that helped me. The material I read was * various LessWrong writings * PJ Eby's Thinking Things Done * Succeed: How We Can Reach Our Goals by Heidi Halvorson * Switch: How to Change When Change Is Hard by Chip and Dan Heath * Feeling Good: The New Mood Therapy by David D. Burns * The Procrastinat

Some people in a similar position recruit other people to police us when our ability to police ourselves is exhausted/inadequate. Of course, this requires some kind of policing mechanism... e.g., whereby the coach can unilaterally withhold rewards/invoke punishments/apply costs in case of noncompliance.
0Paul Crowley11y
Have you tried setting very small and easy goals and seeing if you can meet those?
0Dahlen11y
I have made many incremental steps towards modifying some behaviours in a desired direction, yes, but they don't tend to be consciously directed. When they are, I abandon them soon; no habit formation occurs of these attempts. I am making progress, but it seems to be largely outside of my control.
0Qiaochu_Yuan11y
Have you tried Beeminder? That's less self-policing and more Beeminder policing you, as long as you haven't sunk so low as to lie to Beeminder. Alternatively, there are probably things you can do to cultivate self-control in general, although I'm not sure what those would be (I've been practicing with denying myself various things for awhile now).
2Dahlen11y
No way, it's the stupidest thing I could do with my already very very limited financial resources. That sort of way of motivating yourself is really sort of a luxury, at least when viewed from my position. Lower middle class folks in relatively poor countries can't afford to gamble their meagre savings on a fickle motivation; any benefit I could derive from it is easily outweighted by the very good chance of digging myself into a financial hole... so, I can't take that risk.
9Qiaochu_Yuan11y
I can think of much stupider things. Doesn't the fact that you have limited finances make this an even better tool to use (in that you'll be more motivated not to lose money)? The smallest pledge is $5 and if you stay on track (it helps to set small goals at first) you never have to pay anything. I think you're miscalibrated about how risky this is. And how were you planning on obtaining nootropics if your finances are so limited?
2Dahlen11y
... No. It doesn't work like that at all. That's the definition of digging myself into a hole. Will I be struggling to get out of it all the more so? Yes, I will, but at a cost greater than what I was initially setting out to accomplish. I'd rather be unmotivated than afraid of going broke. Possibly. The thing is, around here, even $5 is... Well, not much by any measure, but it doesn't feel negligible, you know what I'm saying? Someone of median income couldn't really say it's no big deal if they come to realize the equivalent of $5 is missing from their pockets. It probably doesn't feel like that to an American, so I understand why you may think I'm mistaken. I can afford to spend a few bucks on a physical product with almost guaranteed benefits. I can't afford to bet money on me doing things I have a tendency to do very rarely. In one case I can expect to get definite value from the money I spend, in the other I'm basically buying myself some worries. (I should, perhaps, add that the things I want to motivate myself to do don't have a chance of earning me income any time soon.) Of course; it wasn't meant to be understood literally. -- The bottom line is, they're not getting my money. I'm really confident that it's a good decision, and have really good reasons to be suspicious of any attempts to get me to pay for something, and there are really many things out there that are obviously useful enough that I don't need to be persuaded into buying them. So... I appreciate that you mean to help, it's more than one can ask from strangers, but I strongly prefer alternatives that are either free, guaranteed, or ideally both.

You could try using Beeminder without giving them money.

A habit I'm working on developing is to ask a mental model of a Manager what I -should- be doing right now. As long as I don't co-opt the Manager, and as long as there's a clearly preferable outcome, it seems to work pretty well. Even when there isn't a clearly preferable outcome, the mental conversation helps me sort out the issue. (And having undertaken this, I've discovered I used to have mental conversations with myself all the time, and at some point lost and forgot the habit.)
2DaFranker11y
I've tried similar approaches. From that opening line and with sane priors, you can probably get a pretty good idea of what the results were. For me, and I suspect many others for whom all self-help and motivational techniques and hacks just "inexplicably" fail and which "they must be doing wrong", the problem is almost entirely within one single, simple assumption that seems to work naturally for the authors, but which is for me a massive amount of cognitive workload that is continuously taxing on my mental energy. And said assumption that I refer to is precisely here: The question I shall ask, to illustrate my point, is: If you were programming a computer to do this (e.g. open a chat window with someone posing as a Manager for the appropriate discussion), how would you go about it? More importantly, how does the program know when to open the window? Suppose the program has access to your brain and can read what you're thinking, and also has access to a clock. Well, there are three most obvious, simple answers, in order of code complexity: 1. Keep the chat window open all the time. This is obviously costly attention-wise (but not for the program), and the window is always in the way, and chances are that after a while you'll stop noticing that window and never click on it anymore, and it will lose all usefulness. It then becomes a flat tax on your mind that is rendered useless. 2. Open the chat window at specific intervals. This brings another question: how often? If it's too often, it gets annoying, and it opens too many times when not needed, and eventually that'll cause the same problems as solution 1. If it's not often enough, then you won't get much benefit from it whenever you would need it. And even if it is a good interval, you'll still sometimes open it when not needed, or not open it when it was needed more often that day or in the middle of an interval. We can do better. 3. Look for the kind of situations in which the Manager will help you, by
3OrphanWilde11y
Am I correct in ascertaining that your issue is less making the right decisions, and more trying to remember to consciously make decisions at all?
0DaFranker11y
In some sense, yes. However, sometimes it gets much more complex. It can very well happen that I insert a trigger to "must go do dishes once X is done", but then I think "Hmm, maybe I should go do dishes" at some point in the future when I'm in-between activities, and X happens to be done, but (and this is the gut-kicking bastard): Thinking that I should do the dishes is not properly linked to checking whether X is done, and thus I don't see the process that tells me that X is done so I should do the dishes! And therefore what happens afterwards, instead of realizing that X is done me getting up to do dishes, is me thinking "yeah I should, but meh, this is more interesting". And X has never crossed my mind during this entire internal exchange. And now I'm back to tabsploding / foruming / gaming. And then three hours later I realize that all of this happened when I finally think of X. Oops. So yes. "Trying to remember" is an active-only process for me. Something must trigger it. The thoughts and triggers do not happen easily and automatically at the right and proper times. Once the whole process is there and [Insert favorite motivational hack] is actually in my steam-of-consciousness, then this whole "motivation" thing becomes completely different and much easier to solve. Unfortunately, I do not yet have access to technology of sufficient sophistication to externalize and fully automate this process. I've dreamed of it for years though.
1OrphanWilde11y
This may be a stupid question, but I have to ask: Have you tried designing solutions for this problem? Pomodoro and the like are designed to combat akrasia; they're designed to supplement or retrain willpower. They're solutions for the wrong problem; your willpower isn't entering into it. Hypothesis: Pomodoro kind-of sort-of worked for you for a short period of time before inexplicably failing. You might not have even consciously noticed it going off.
3DaFranker11y
If I'm reading you correctly, that hypothesis is entirely correct. Pomodoro is also not the only thing where this has happened. In most cases, I don't consciously realize what happens until later, usually days or weeks after the fact. I've tried coming up with some solutions to the problem, yes, but so far there's only three avenues that I've tried that had promising results: * Use mental imagination techniques to train habits: imagine arriving in situation or getting feelings X, anchor that situation or feeling to action Y. This works exceptionally well and easily for me, but... Yep. Doing the training is itself something that suffers from this problem. I would need to use it to train using it. Which I can't, 'caus I'm not good enough at it (I tried). Some bootstrapping would be required for this to be a reliable method, but it's also in itself a rather expensive and time-consuming exercise (not the same order of magnitude as constant mindfulness, though), so I'd prefer better alternatives. * Spam post-its or other forms of fixed visual / auditory reminders in the appropriate contexts, places and times. Problem is, this becomes like the permanent or fixed-timed chat windows in the programmed Manager example - my brain learns to phase them out or ignore them, something which is made exponentially worse when trying to scale things up to more things. * Externalize and automate using machines and devices. Setting programmatic reminders on my phone using tasker is the best-working variant I've found so far, but the app is difficult to handle and crashes often - and every single time it crashes, I lose everything (all presets, all settings, all events, everything - as if I had reinstalled the app completely). I gave up on that after about the fourth time I spent hours configuring it and then lost everything from a single unrelated crash.
0OrphanWilde11y
I actually suffer from exactly the same issue. (I opted to try to run the Manager app full-time, although I'm not having a lot of luck training myself to actually do it. I figure any wasted brain cycles probably weren't being used anyways on account that I couldn't remember to do things that required using them.) Thus far the only real "hack" I've worked out is to constantly change reminder mechanisms. I'm actually fine with highly disruptive alerts - my favorite alarm is also the most annoying - but the people around me tend to hate them. Hacks aside, routine has been the only thing I've found that helps, and helps long-term. And given my work schedule, which can vary from "Trying to find something to do" to "Working eighteen hours days for two weeks straight" with just about everything in the middle, routine has been very hard to establish. However, I have considerably better luck limiting my routine; waking up at 6 AM every day, and dedicating this time strictly to "Stuff that needs doing", has worked for me in the past. (Well, up until a marathon work period.)

nicotine has been a significant help with motivation. I only vape eliquid with nicotine when I am studying. This seems to have resulted in a large reduction in ugh fields.

It depends on what you get way too much to give a blanket category answer. Adderall/other ADD medications have a proven track record. Modafinil is likely also helpful, esp with concentration and having more time in general to get things done. Honestly, if you're anything like me, you'd get a lot more mileage out of implementing and organization and time management system.

I've been reading Atlas Shrugged and seem to have caught a case of Randianism. Can anyone recommend treatment?

My own deconversion was prompted by realizing that Rand sucked at psychology. Most of her ideas about how humans should think and behave fail repeatedly and embarrassingly as you try to apply it to your life and the lives of those around you. In this way, the disease gradually cures itself, and you eventually feel like a fool.

It might also help to find a more powerful thing to call yourself, such as Empiricist. Seize onto the impulse that it is not virtuous to adhere to any dogma for its own sake. If part of Objectivism makes sense, and seems to work, great. Otherwise, hold nothing holy.

Michael Huemer explains why he isn't an Objectivist here and this blog is almost nothing but critiques of Rand's doctrines. Also, keep in mind that you are essentially asking for help engaging in motivated cognition. I'm not saying you shouldn't in this case, but don't forget that is what you are doing.

With that said, I enjoyed Atlas Shrugged. The idea that you shouldn't be ashamed for doing something awesome was (for me, at the time I read it) incredibly refreshing.

2mstevens11y
Quoting from the linked blog: "Assume that a stranger shouted at you "Broccoli!" Would you have any idea what he meant? You would not. If instead he shouted "I like broccoli" or "I hate broccoli" you would know immediately what he meant. But the word by itself, unless used as an answer to a question (e.g., "What vegetable would you like?"), conveys no meaning" I don't think that's true? Surely the meaning is an attempt to bring that particular kind of cabbage to my attention, for as yet unexplained reasons.
1Desrtopa11y
That's a possible interpretation, but I wouldn't say "surely." Some other possibilities. The person picked the word apropos of nothing because they think it would be funny to mess with a stranger's head. It's some kind of in-joke or code word, and they're doing it for the amusement of someone else who's present (or just themselves if they're the sort of person who makes jokes nobody else in the room is going to get.) The person is confused or deranged.
3TheOtherDave11y
If I heard someone shout "Broccoli" at me without context, my first assumption would be that they'd actually said something else and I'd misunderstood.
0mstevens11y
But this doesn't seem particularly different from the ambiguity in all language. The linked site seems to suggest there's some particular lack of meaning in isolated words.
2mstevens11y
My reaction to Rand is pretty emotional, rather than "I see why her logic is correct!", which I think justifies the motivated cognition aspect a little bit.
-2blacktrance11y
Some of Huemer's arguments against Objectivism are good (particularly the ones about the a priori natures of logic and mathematics), but his arguments against the core of Objectivism (virtue ethical egoism) fall short, or at best demonstrate why Objectivism is incomplete rather than wrong.
-1OrphanWilde11y
His arguments against her ethical system seem... confused. She pretty much acknowledged that life as a good thing is taken as a first principle, what he calls a suppressed premise - she was quite open about it, in fact, as a large part of her ethical arguments were about ethical systems which -didn't- take life as a good thing as a first principle. His arguments about a priori knowledge, however, are fatally flawed. What he calls a priori knowledge only seems intuitive once you've understood it. Try teaching addition to somebody sometime. Regardless of whether a priori truths exist, we only recognize their truth by reference to experience. Imagine you live someplace where addition and subtraction never work - addition wouldn't be intuitively true; it would be nonsense. Do you think you could get a child to grasp addition while you perform sleight of hand and change the number of apples or whatnot as you demonstrate the concepts? He's regarding knowledge from the perspective of somebody who has already internalized it. You have to have a strong grasp of abstract concepts before you can start building the kind of stuff he insists is a priori, concepts which are built up through experience with things like language. Mathematics wasn't discovered, it was invented, just as much as an electric motor was invented. (You can suppose that mathematics exists in an infinite plane of possible abstractions, but the same is true of the electric motor.) That we chose the particular mathematics we did is a result of the experiences we as a species have had over the past few dozen thousand years. (Or, to take a page out of Descartes - what would his a priori knowledge look like if a devil were constantly changing the details of the world he lived in? Playing sleight of hand with the apples, as it were?)
3blacktrance11y
The idea of a priori knowledge is not that it's intuitive, but that it is not dependent on experience for it to be conceivable. Though addition may be hard to teach without examples, it abstractly makes sense without reference to anything in the physical world. Similarly, the truth of the statement "a bachelor is an unmarried man" does not require any experience to know - its truth comes from the definition of the word "bachelor".
1Strelok11y
If I am understanding your statement here correctly, you are saying that a priori knowledge hinges on the idea that concepts can be acquired independently of experience. If that is what you are saying, then you would be incorrect. Very few philosophers who accept the idea of a priori knowledge—or more appropriately: a priori justification—think that human-beings ever acquire concepts innately or that they can otherwise conceive of them independently of experience. A proposition is knowable a priori if it is justifiable by appeal to pure reason or thought alone. Conversely, a proposition is knowable a posteriori if it is justifiable in virtue of experience; where any relevant, constitutive notion of experience would have as its meaning (a) some causally conditioned response to particular, contingent features of the world, and (b) doxastic states that have as their content information concerning such contingent features of the actual world as contrasted with other possible worlds.

Somebody defined the operation of addition - it did not arise out of pure thought alone, as is evidenced by the fact that nobody bothered to define some other operation by which two compounds could be combined to produce a lesser quantity of some other compound (at least until people began formalizing chemistry). There are an infinite number of possible operations, most of which are completely meaningless for any purpose we would put them to. Knowledge of addition isn't knowledge at all until you have something to add. "Qwerms are infantile eloppets." Is this a true statement or not? I could -define- a qwerm to be an infantile eloppet, but that doesn't represent any knowledge; in the pure abstract, it is an empty referential, devoid of meaning. Everything in the statement "a bachelor is an unmarried man" is tied to real-world things, whatever knowledge is contains there is experience driven; if the words mean something else - and those words are given meaning by our experiences - the statement could be true or false. Kant, incidentally, did not define a priori knowledge to be that which is knowable without experience (the mutation of the original term which Ayn Rand harshly criticized), but rather that which is knowable without reference to -specific- experience, hence his use of the word "transcendent". If putting one rock and another together results in three rocks, our concept of mathematics would be radically different, and addition would not merely fail to reflect reality, it would not for any meaningful purpose exist. Transcendent truths are arrived at through experience, they simply don't require any -particular- experience to be had in order to be true. In Kantian terms, a priori, I know if I throw a rock in the air it will fall. My posterior knowledge will be that the rock did in fact fall. There are other transcendental things, but transcendental knowledge is generally limited to those things which can be verified by experience (he argued that transcend
0[anonymous]11y
The problem here is that you seem to be presupposing the odd idea that, in order for any proposition to be knowable a priori, its content must also have been conceived a priori. (At least for the non-Kantian conceptions of the a priori). It would be rare to find a person who held the idea that a concept be acquired without having any experience related to it. Indeed, such an idea seems entirely incapable of being vindicated. If I expressed a proposition such as "nothing can be both red and green all over at the same time" to a person who had no relevant perceptual experience with the colors I am referring to and who had failed to acquire the relevant definitions of the color concepts I am using, then that proposition would be completely nonsensical and unanalyzable for such a person. However, this has no bearing on the concept of a priori knowledge whatsoever. The only condition for a priori knowledge is for the expressed proposition be justifiable by appeal to pure reason.

Laughs I'm an Objectivist by my own accord, but I may be able to help if you find this undesirable. The shortest - her derivations from her axioms have a lot of implicit and unmentioned axioms thrown in ad-hoc. One problematic case is her defense of property - she implicitly assumes no other mechanism of proper existence for humans is possible. (And her "proper existence" is really slippery.) This isn't necessarily a rejection - as mentioned, I am an Objectivist - but it is something you need to be aware of and watch out for in her writings. If a conclusion doesn't seem to be quite right or doesn't square with your own conception of ethics, try to figure out what implicit axioms are being slipped in. Reading Ayn Rand may be the best cure for Randianism, if Objectivism isn't a natural philosophy for you, which by your apparent distress it isn't. (Honestly, though, I'd stay the hell away from most of the critics, who do an absolutely horrible job of attacking the philosophy. They might be able to cure you of Randianism, but largely through misinformation and unsupported emotional appeals, which may just result in an even worse recurrence later.)
1Viliam_Bur11y
Please correct me if I'm wrong, but it seems to me that she also did some variant of "Spock Rationality". More precisely, it seems to me as if her heroes have one fixed emotion (mild curious optimism?) all the time; and if someone doesn't, that is only to show that Hero1 is not as perfect as Hero2 whose emotional state is more constant.
5OrphanWilde11y
I've mentioned this here before, but prior to reading Atlas Shrugged, I truly believed in Spock Rationality. I used meditation to eliminate emotions as a teenager because I saw them as irrelevant. Atlas Shrugged convinced me that emotions were a valuable thing to have. So I don't really see Spock Rationality in the characters. The closest any of the characters comes to that is Galt, and it is heavily implied he went through the same kind of utter despair as all the other characters in the book. It's more or less stated outright that the Hero characters experience greater emotions, in wider variety, than other characters, and particularly the villains; the level emotions of, for example Galt, is not a result of having no emotions, but having experienced such suffering that what he experiences in the course of the book is insignificant by comparison. (Relentless optimism and curiousity are treated as morally superior attitudes, I grant, but I'd point out that this is a moral standard held to some degree here as well. Imagine the response to somebody who insisted FAI was impossible and we were all doomed to a singularity-induced hell. This community is pretty much defined by curiousity, and to a lesser but still important extent optimism, in the sense that we can accomplish something.)
2Viliam_Bur11y
Some explanation: Recently I watched the beginning of Atlas Shrugged: Part I, and there was this dialog, about 10 minutes from the beginning: I didn't watch the whole movie yet, and I don't remember whether this was also in the book. But this is what made me ask. (Also some other things seemed to match this pattern.) Of course there are other explanations too: Dagny can simply be hostile to James; both implicitly understand the dialog is about a specific subset of feelings; or this is specifically Dagny's trait, perhaps because she hasn't experienced anything worth being emotional about, yet. EDIT: Could you perhaps write an article about the reasonable parts of Objectivism? I think it is worth knowing the history of previous self-described rationality movements, what they got right, what they got wrong, and generally what caused them to not optimize the known universe.
1[anonymous]11y
I thought the exchange was supposed to be interpreted sarcastically, but the acting in the movie was so bad it was hard to tell for sure. Having read most of Rand during a misspent youth, I agree with OrphanWilde's interpretation of Rand's objectivist superheroes being designed specifically to feel emotions that are "more real" than everyday "human animals." For what it's worth, in my opinion the only reasonable part of Objectivism is contained in The Romantic Manifesto, which deals with all of this "authentic emotions" stuff in detail.
0NancyLebovitz11y
I also read it as Dagny being sarcastic, or at least giving up on trying to convey anything important to James. (I haven't seen the movie-- Dagny was so badly miscast that I didn't think I could enjoy it.) I think a thing that's excellent in Rand not put front and center by much of anyone else is that wanting to do things well is a primary motivation for some people.

I'd have to buy another copy of the book (I have a tendency to give my copies away - I've gone through a few now), so I'm not sure. In the context of the book, this would be referring to a specific subset of feelings (or more particularly, guilt, which Ayn Rand utterly despised, and which James was kind of an anthropomorphism of). Whether that's an appropriate description in the context of the scene itself, I'm not sure. (God the movie sucked. About the only thing I liked was that the villains were updated to fit the modern era to be more familiar. They come off as strawmen in the book unless you're familiar with the people they're caricatures of.)

I initially thought she was being sarcastic. However on seeing this discussion I find the "specific subset of feelings" theory more plausible. She's rejecting the "feelings" James has.

Heinlein? I found Stranger in a Strange Land to be an interesting counterpoint to Atlas Shrugged. Both feature characters with super-human focus / capability (Rearden and Valentine Micheal Smith). And they have totally different effects on societies superficially similar to each other (and to our own). There's more to say about Rand in particular, but we should probably move to the media thread for that specifically (Or decline to discuss for Politics is the Mindkiller reasons). Suffice it to say that uncertainty about how to treat the elite productive elements in society predates the 1950s and 1960s.

Genuine question: What do you find appealing about it? I've always found the writing impenetrable and the philosophy unappealing.
0mstevens11y
The writing, I agree, is pretty bad, and she has an odd obsession with trains and motors. I can just about understand the "motor" part because it allows some not very good "motor of the world" metaphors. The appealing part is the depiction of the evil characters as endlessly dependant on the hero characters, and their view of them as an inexhaustible source of resources for whatever they want, and the rejection of this.
3Viliam_Bur11y
The obsession with trains is probably because in era when Ayn Rand lived, people working with trains were an intellectual elite. They (1) worked with technology, and often (2) travelled across the world and shared ideas with similar people. If you worked at a railroad, sometimes you got free rides anywhere as an employment benefit. It was an era before internet, where the best way to share ideas with bright people was to meet them personally. In other words, if she lived today, she would probably write about hackers, or technological entrepreneurs. John Galt would be the inventor of internet, or nanotechnology, or artificial intelligence. (And he would use modafinil instead of nicotine.)

I don't have a link, but I remember reading somewhere that originally the altruism was defined as a self-destructive behavior -- ignoring one's own utility function and only working for the others -- and only later it was modified to mean... non-psychopatology. In other words, it was the "egoism" which became a strawman by not being allowed to become more reasonable, while its opposite the "altruism" was allowed to become more sane than originally defined. In a typical discussion, the hypothetical "altruist" is allowed to reflect on their actions, and try to preserve themself (even if only to be able to help more people in the future), while the hypothetical "egoist" is supposed to be completely greedy and short-sighted.
0OrphanWilde11y
http://hubcap.clemson.edu/~campber/altruismrandcomte.pdf Page 363 or so. Auguste Comte coined the term "altruist", and it's been toned down considerably from his original version of it, which held, in James Feiser's terms, that "An action is morally right if the consequences of that action are more favorable than unfavorable to everyone except the agent" It's a pretty horrific doctrine, and the word has been considerably watered down since Comte originally coined it. That's pretty much the definition that Ayn Rand assaulted.
0Richard_Kennaway11y
Depends on the discussion. Reasonable egoism is practically the definition of "enlightened self-interest".
4Viliam_Bur11y
Yeah, that's the point. To get the answer "egoism", one defines egoism as enlightened self-interest, and altruism as self-destructive behavior. To get the answer "altruism", one defines altruism as enlightened pro-social behavior, and egoism as short-sighted greed. Perhaps less extremely than this, but usually from the way these words are defined you understand which one of them is the applause light for the person asking the question. (I typically meet people for whom "altruism" is the preferred applause light, but of course there are groups which prefer "egoism".)

More Right

Edit: We reached our deadline on May 1st. Site is live.

Some of you may recall the previous announcement of the blog. I envisioned it as a site that discusses right wing ideas. Sanity but not value checking them. Steelmanning both the ideas themselves and the counterarguments. Most of the authors should be sympathetic to them, but a competent loyal opposition should be sought out. In sum a kind of inversion of the LessWrong demographics (see Alternative Politics Question). Outreach will not be a priority, mutual aid on an epistemically tricky path of knowledge seeking is.

The current core group working on making the site a reality consists of me, ErikM, Athrelon, KarmaKaiser and MichaelAnissimov and Abudhabi. As we approach launch time I've just sent out an email update to other contributors and those who haven't yet contributed but have contacted me. If you are interested in the hard to discuss subjects or the politics and want to join as a coauthor or approved commenter (we are seeking more) send me a PM with an email adress or comment here.

7bogus11y
This is a great idea. We should create rationalist blogs for other political factions too, such as progressivism, feminism, anarchism, green politics and others. Such efforts could bring our programme of "raising the sanity waterline" to the public policy sphere -- and this might even lay some of the groundwork for eventually relaxing the "no politics at LW" rule.
7[anonymous]11y
As I wrote before: I don't expect LessWrong itself to become a good venue to discuss politics. I do think LessWrong could keep its spot at the center of a "rationalist" blogosphere that may be slowly growing. Discussions between different value systems part of it might actually be worth following! And I do think nearly all political factions within such a blogosphere would find benefits in keeping their norms as sanity friendly as possible.
0Viliam_Bur11y
I would like to see one site to describe them all. To describe all those parts which can be defended rationally, with clear explanations and evidence.
0bogus11y
Yes, the issue-position-argument (IPA) model was developed for such purposes, and similar models are widely cited in the academic literature about argumentation and computer support for same, etc. (One very useful elaboration of this is called TIPAESA, for: time, issue, position, argument, evidence, source, authority. Unfortunately, I do not know of a good reference for this model; it seems that it was only developed informally, by anonymous folks on some political wikis.) But it's still useful to have separately managed sites for each political faction, if only so that each faction can develop highly representative descriptions of their own positions.

On the other, toy demos + "this could be the solution to AI!" => likely to be a damp squib.
4gwern11y
I've skimmed the paper and read the summary publicity, and I don't really get how this could be construed as a general intelligence. At best, I think they may've encoded a simple objective definition of a convergent AI drive like 'keep your options open and acquire any kind of influence' but nothing in it seems to map onto utility functions or anything like that.
0Richard_Kennaway11y
I think that's an accurate informal summary of their basic mechanism. Personally, I'm not impressed by utility functions (or much else in AGI, for that matter), so I don't rate the fact that they aren't using them as a point against.
2gwern11y
I do, because it seems like in any nontrivial situation, simply grasping for entropies ignores the point of having power or options, which is to aim at some state of affairs which is more valuable than others. Simply buying options is worthless and could well be actively harmful if you keep exposing yourself to risks you could've shut down. They mention that it works well as a strategy in Go playing... but I can't help but think that it must be in situations where it's not feasible to do any board evaluation at all and where one is maximally ignorant about the value of anything at that point.
-4timtyler11y
As I understand it, it's more a denial of that claim. The point is to maximise entropy, and values are a means to that end. Obviously, this is counter-intuitive, since orthodoxy has this relationship the other way around: claiming that organisms maximise correlates of their own power - and the entropy they produce is a byproduct. MaxEnt suggests that this perspective may have things backwards.
0drethelin11y
what's your preferred system for encoding values?
0Richard_Kennaway11y
"Value" is just another word for "utility", isn't it? It's the whole idea of utility maximisation as a fundamental principle that I think is misguided. No, I don't have a better idea; I just think that that one is a road that, where AGI is concerned, leads nowhere. But AGI is not something I work on. There is no reason for anyone who does to pay any attention to my opinions on the subject.
-2timtyler11y
The idea is that entropy can be treated as utility. Thus entropy maximisation. Modern formulizations are largely based on ideas discovered by E. T. Jaynes. Here is Roderick Dewar explaining the link.
2gwern11y
I'm aware of maxent (and that's one reason why in my other comment I mentioned the Go playing as probably reflecting a situation of maximum ignorance), but I still do not see how maximizing entropy can possibly lead to fully intelligent utility-maximizing behavior, or if it is unable to do so, why we would give a damn about what maximizing entropy does. What is the maximal entropy state of the universe but something we would abhor like a uniform warm gas? To return to the Go playing: entropy maximization may be a useful heuristic in some positions - but the best Go programs do not purely maximize entropy and ignore the value of positions or ignore the value of winning.
-2timtyler11y
That's an argument from incredulity, though. Hopefully, I can explain: If you have a maximiser of A, the ability to constrain that maximiser, and the ability to generate A, you can use it to maximise B by rewarding the production of B with A. If A = entropy and B = utility, Q.E.D. Of course if you can't constrain it you just get an entropy maximiser. That seems like the current situation with modern ecosystems. These dissipate mercilessly, until no energy gradients - or anything else of possible value - is left behind. By their actions shall ye know them. Humans generate large quantities of entropy, accelerating universal heat death. Their actions clearly indicate that they don't really care about averting universal heat death. In general, maximisers don't necessarily value the eventual results of their actions. A sweet taste maximiser might not value tooth decay and obesity. Organisms behave as though they like dissipating. They don't necessarily like the dissipated state their actions ultimately lead to. Maximisation is subject to constraints. Go programs are typically constrained to play go. An entropy maximiser whose only actions were placing pieces on go boards in competitive situations might well attempt to play excellent go - to make humans feed it power and make copies of it. Of course, this is a bit different from what the original article is talking about. That refers to "maximizing accessible future game states". If you know go, that's pretty similar to winning. To see how, consider a variant of go in which both passing and suicide are prohibited.
2gwern11y
That seems to simply be buck-passing. What does this gain us over simply maximizing B? If we can compute how to maximize a predicate like A, then what stops us from maximizing B directly? Pretty similar, yet somehow, crucially, not the same thing. If you know go, consider a board position in which 51% of the board has been filled with your giant false eye, you move, and there is 1 move which turns it into a true eye and many moves which don't. The winning-maximizing move is to turn your false eye into a true eye, yet this shuts down a huge tree of possible futures in which your false eye is killed, thousands of stones are removed from the board, and you can replay the opening with its beyond-astronomical number of possible futures...
0timtyler11y
You said you didn't see how having an entropy maximizer would help with maximizing utility. Having an entropy maximizer would help a lot. Basically maximizers are very useful things - almost irrespective of what they maximize. Sure. I never claimed they were the same thing. If you forbid passing, forbid suicide and aim to mimimize your opponent's possible moves, that would make a lot more sense - as a short description of a go-playing strategy.
6gwern11y
So maximizers are useful for maximizing? That's good to know.
-2timtyler11y
That's trivializing the issue. The idea is that maximisers can often be repurposed to help other agents (via trade, slavery etc). It sounds as though you originally meant to ask a different question. You can now see how maximizing entropy would be useful, but want to know what advantages it has over other approaches. The main advantage I am aware of associated with maximizing entropy is one of efficiency. If you maximize something else (say carbon atoms), you try and leave something behind. By contrast, an entropy maximizer would use carbon atoms as fuel. In a competition, the entropy maximizer would come out on top - all else being equal. It's also a pure and abstract type of maximisation that mirrors what happens in natural systems. Maybe it has been studied more.
0gwern11y
I already saw how it could be useful in a handful of limited situations - that's why I brought up the Go example in the first place! As it stands, it sounds like a limited heuristic and the claims about intelligence grossly exaggerated.
0timtyler11y
Entropy maximisation purports to explain all adaptation. However, it doesn't tell us much that we didn't already know about how to go about making good adaptations. For one thing, entropy maximisation is a very old idea - dating back at least to Lotka, 1922.

I have a super dumb question.

So, if you allow me to divide by zero, I can derive a contradiction from the basic rules of arithmetic to the effect that any two numbers are equal. But there's a rule that I cannot divide by zero. In any other case, it seems like if I can derive a contradiction from basic operations of a system of, say, logic, then the logician is not allowed to say "Well...don't do that".

So there must be some other reason for the rule, 'don't divide by zero.' What is it?

We don't divide by zero because it's boring.

You can totally divide by zero, but the ring you get when you do that is the zero ring, and it only has one element. When you start with the integers and try dividing by nonzero stuff, you can say "you can't do that" or you can move out of the integers and into the rationals, into which the integers embed (or you can restrict yourself to only dividing by some nonzero things - that's called localization - which is also interesting). The difference between doing that and dividing by zero is that nothing embeds into the zero ring (except the zero ring). It's not that we can't study it, but that we don't want to.

Also, in the future, if you want to ask math questions, ask them on math.stackexchange.com (I've answered a version of this question there already, I think).

0[anonymous]11y
Thanks, I think that answers my question.
0Kawoomba11y
What do you mean by "you get"? Do you mean Wheel theory or what?

I mean if you localize a ring at zero you get the zero ring. Equivalently, the unique ring in which zero is invertible is the zero ring. (Some textbooks will tell you that you can't localize at zero. They are haters who don't like the zero ring for some reason.)

0A1987dM11y
BTW, how comes the ring with one element isn't usually considered a field?

The theorems work out nicer if you don't. A field should be a ring with exactly two ideals (the zero ideal and the unit deal), and the zero ring has one ideal.

We often want the field without zero to form a multiplicative group, and this isn't the case in the ring with one element (because the empty set lacks an identity and hence isn't a group). Indeed we could take the definition of a field to be and this is fairly elegant.

The rule isn't that you cannot divide by zero. You need a rule to allow you to divide by a number, and the rule happens to only allow you to divide by nonzero numbers.

There are also lots of things logicians can tell you that you're not allowed to do. For example, you might prove that (A or B) is equivalent to (A or C). You cannot proceed to cancel the A's to prove that B and C are equivalent, unless A happens to be false. This is completely analogous to going from AB = AC to B = C, which is only allowed when A is nonzero.

0kpreid11y
However, {false, true} - {true} has only one member, and so values from it become constant, whereas ℝ - {0} has many members and can therefore remain significant.

For the real numbers, the equation a x = b has infinitely many solutions if a = b = 0, no solutions if a = 0 but b ≠ 0, and exactly one solution whenever a ≠ 0. Because there's nearly always exactly one solution, it's convenient to have a symbol for "the one solution to the equation a x = b" and that symbol is b / a; b but you can't write that if a = 0 because then there isn't exactly one solution.

This is true of any field, almost by definition.

3latanius11y
Didn't they do the same with set theory? You can derive a contradiction from the existence of "the set of sets that don't contain themselves"... therefore, build a system where you just can't do that. (of course, coming from the axioms, it's more like "it wasn't ever allowed", like in Kindly's comment, but the "new and updated" axioms were invented specifically so that wouldn't happen.)
-1OrphanWilde11y
We divide by zero all the time, actually; derivatives are the long way about dividing by zero. We just work very carefully to cancel the actual zero out of the equation. The rule is less "Don't divide by zero", as much as "Don't perform operations which delete your data." Dividing by zero doesn't produce a contradiction, it eliminates meaning in the data. You -can- divide by zero, you just have to do so in a way that maintains all the data you started with. Multiplying by zero eliminates data, and can be used for the same destructive purpose.
4[anonymous]11y
I completely fail to understand how you got such a doctrine on dividing by zero. Mathematics just doesn't work like that.
0OrphanWilde11y
Are you denying this as somebody with strong knowledge of mathematics? (I need to know what prior I should assign to this conceptualization being wrong. I got it from a mathematics instructor, quite possibly the best I ever had, in his explanation on why canceling out denominators doesn't fix discontinuities.) ETA: The problem he was demonstrating it with focused more on the error of -adding- information than removing it, but he did show us how information could be deleted from an equation by inappropriately multiplying by or dividing by zero, showing how discontinuities could be removed or introduced. He also demonstrated a really weird function involving a square root which had two solutions, one of which introduced a discontinuity, one of which didn't.
3[anonymous]11y
I'm a graduate student, working on my thesis. I accept that this is some pedagogical half-truth, but I just don't see how it benefits people to pretend mathematics cares about whether or not you "eliminate meaning in the data." There's no meta-theorem that says information in an equation has to be preserved, whatever that means.

0[anonymous]11y
Thanks, that's helpful. But I guess my point is that it seems to me to be a problem for a system of mathematics that one can do operations which, as you say, delete the data. In other words, isn't it a problem that it's even possible to use basic arithmetical operations to render my data meaningless? If this were possible in a system of logic, we would throw the system out without further ado. And while I can construct a proof that 2=1 (what I called a contradiction, namely that a number be equal to its sucessor) if you allow me to divide by zero, I cannot do so with multiplications. So the cases are at least somewhat different.
7Jonii11y
Qiaochu_Yuan already answered your question, but because he was pretty technical with his answer, I thought I should try to simplify the point here a bit. The problem with division by zero is that division is essentially defined through multiplication and existence of certain inverse elements. It's an axiom in itself in group theory that there are inverse elements, that is, for each a, there is x such that ax = 1. Our notation for x here would be 1/a, and it's easy to see why a 1/a = 1. Division is defined by these inverse elements: a/b is calculated by a * (1/b), where (1/b) is the inverse of b. But, if you have both multiplication and addition, there is one interesting thing. If we assume addition is the group operation for all numbers(and we use "0" to signify additive neutral element you get from adding together an element and its additive inverse, that is, "a + (-a) = 0"), and we want multiplication to work the way we like it to work(so that a(x + y) = (ax) + (a*y), that is, distributivity hold, something interesting happens. Now, neutral element 0 is such that x + 0 = x, this is by definition of neutral element. Now watch the magic happen: 0x = (0 + 0)x = 0x + 0x So 0x = 0x + 0x. We subtract 0x from both sides, leaving us with 0x = 0. Doesn't matter what you are multiplying 0 with, you always end up with zero. So, assuming 1 and 0 are not the same number(in zero ring, that's the case, also, 0 = 1 is the only number in the entire zero ring), you can't get a number such that 0*x = 1. Lacking inverse elements, there's no obvious way to define what it would mean to divide by zero. There are special situations where there is a natural way to interpret what it means to divide by zero, in which cases, go for it. However, it's separate from the division defined for other numbers. And, if you end up dividing by zero because you somewhere assumed that there actually was such a number x that 0*x = 1, well, that's just your own clumsiness. Also, you can prove 1=2 if

Excellent explanation, thank you. I've been telling everyone I know about your resolution to my worry. I believe in math again. Maybe you can solve my similarly dumb worry about ethics: If the best life is the life of ethical action (insofar as we do or ought to prefer to do the ethically right thing over any other comforts or pleasures), and if ethical action consists at least largely in providing and preserving the goods of life for our fellow human beings, then if someone inhabited the limit case of the best possible life (by permanently providing immortality, freedom, and happiness for all human beings), wouldn't they at the same time cut everyone else off from the best kind of life?
4drethelin11y
Ethical action is defined by situations. The best life in the scenario where we don't have immortality freedom and happiness is to try to bring them about, but the best life in the scenario where we already have them is something different.
0[anonymous]11y
Good! That would solve the problem, if true. Do you have a ready argument for this thesis (I mean "but the best life in the scenario where we already have them is something different.")?
0drethelin11y
"If true" is a tough thing here because I'm not a moral realist. I can argue by analogy for the best moral life in different scenarios being a different life but I don't have a deductive proof of anything. By analogy: the best ethical life in 1850 is probably not identical to the best ethical life in 1950 or in 2050, simply because people have different capacities and there exist different problems in the world. This means the theoretical most ethical life is actually divorced from the real most ethical life, because no one in 1850 could've given humanity all those things and working toward would've taken away ethical effort from eg, abolishing slavery. Ethics under uncertainty means that more than one person can be living the subjectively ethically perfect life even if only one of them will achieve what their goal is because no one knows who that is ahead of time.

You can do the same thing in any system of logic. In more advanced mathematics you're required to keep track of values you've canceled out; the given equation remains invalid even though the cancelled value has disappeared. The cancellation isn't real; it's a notational convenience which unfortunately is promulgated as a real operation in mathematics classes. All those cancelled-out values are in fact still there. That's (one of) the mistakes performed in the proof you reference.
1Jonii11y
This strikes to me as massively confused. Keeping track of cancelled values is not required as long as you're working with a group, that is, a set(like reals), and an operation(like addition) that follows the kinda rules addition with integers and multiplication with non-zero real values do. If you are working with a group, there's no sense in which those canceled out values are left dangling. Once you cancel them out, they are gone. http://en.wikipedia.org/wiki/Group_%28mathematics%29 <- you can check group axioms here, I won't list them here. Then again, canceling out, as it is procedurally done in math classes, requires each and every group axiom. That basically means it's nonsense to speak of canceling out with structures that aren't groups. If you tried to cancel out stuff with non-group, that'd be basically assuming stuff you know ain't true. Which begs a question: What are these structures in advanced maths that you speak of?

Today, I finally took a racial/sexual Implicit Association Test.

I had always more or less accepted that it was, if not perfect, at least a fairly meaningful indicator of some sort of bias in the testing population. Now, I'm rather less confident in that conclusion.

According to the test, in terms of positive associations, I rank black women above black men above white women above white men. I do not think this is accurate.

Obviously, this is an atypical result, but I believe that I received it due to confounding factors which prevented the test from being a... (read more)

Academic research tends to randomize everything that can be randomized, including the orders of the different IAT phases, so your first concern shouldn't be an issue in published research. (The keyword for this is "order effect.")

The IAT is one of several different measures of implicit attitudes which are used in research. When taking the IAT it is transparent to the participant what is being tested in each phase, so people could try harder on some trials than on others, but that is not the case with many of the other tests (many use subliminal priming, e.g. flashing either a black man's face or a white man's face on the screen for 20ms immediately before showing the stimulus that participants are instructed to respond to). The different measures tend to produce relatively similar results, which suggests that effort doesn't have that big of an effect (at least for most people). I suspect that this transparency is part of the reason why the IAT has caught on in popular culture - many people taking the test have the experience of it getting harder when they're doing a "mismatched" pairing; they don't need to rely solely on the website's report of their results.

The survey that you took is not part of the IAT. It is probably a separate, explicit measure of attitudes about race and/or gender (do any of these questions look familiar?).

0Desrtopa11y
None of those questions were on the survey, but some of the questions on the survey were similar. The descriptions of the other measures of implicit attitudes given on that page aren't in-depth enough for me to critique them effectively for methodology. The first question that comes to mind though, is to what extent these tests have been calibrated against associations that we already know about. For example, if people are given implicit association tests which match words with pictures of, say, smiling children with candy versus pictures of people with injuries, how do they score?
0NancyLebovitz11y
I haven't heard of any attempts at comparing implicit association tests to behavior.

Yet another fake number of sex partners self-reported:

0CAE_Jones11y
The trouble is that there are multiple areas of interest, and I'm not sure which is best to focus on: life skills? Technology? Programs that I could improve? Etc. My primary strategy has been to determine the goals of each organization and how much success they've had in achieving them, and the trouble is that these are hard to measure (we can tell how much policy influence NFB has had, at least. I haven't found much about how many of AFB's recommendations have been enacted.).
0RolfAndreassen11y
Then it seems that you should recurse a level: Rather than trying to evaluate the organisations, you should be deciding which of the possible organisation-goals is most important. When you've decided that, judge which organisation best achieves that optimal goal.
2CAE_Jones11y
I still can't find much useful information on the AFB, but the NFB publicizes most of their major operations. The only successful one I've come across so far is the cancellation of the ABC sit com "Good and Evil" (it's worth noting that ABC denied that the NFB protests had anything to do with this). They don't seem to be having success at improving Kendel accessibility, which is more a political matter than a technological one (Amazon eventually cut communications with them). They're protesting Goodwill because 64/165 of their stores pay disabled employees less than minimum wage, in a manner that strikes me as poorly thought out (it seems to me that Goodwill has a much better image than the NFB, so this will most likely cost the NFB a lot of political capital). This isn't really enough for me to determine whether they're powerful, or just loud, but so far it's making me update ever so slightly in favor of just loud. It is worth noting that all of the above information came from publications written by NFB members, mostly hosted on NFB web sites. If my confidence in their abilities is hurt by writings seemingly designed to favor them, I can only imagine what something more objective would look like.

Re: sex... is there anyone with whom you're already having great awesome sex who would be willing to help out with some desensitization? For example, adding role-playing "our first time" to your repertoire? If not, how would you feel about hiring sex workers for this purpose?

Re: lifestyle... list the novel factors (dancing 4 hrs/night, spending time with people rather than alone, sleeping <7 hrs/night, diet changes, etc. etc. etc.). When you're back home, identify the ones that are easy to introduce and experiment with introducing them, one at a time, for a week. If you don't see a benefit, move on to the next one. If none of them work, try them all at once. If that doesn't work, move on to the difficult-to-introduce ones and repeat the process.

Personally, I would guess that several hours of sustained exercise and a different diet are the primary factors, but that's just a guess.

6falenas10811y
The feeling happier part could explain looking and feeling healthier alone. I'm stepping into the realm of guesswork here, but I would say that being around others that you enjoy hanging out with could be the cause, or the increased exercise from dancing so much. Also, explaining the cigarrettes and alcohol, although there are long term risks associated (especially for the cigarettes), that doesn't mean they cause negative short term effects. As for 7 hours of sleep tops, there's evidence that around 7 hours might be best.

The standard strategy seems to be to work up to sex very progressively, going a little further on each encounter, so there's never any bright line to cross. Why is this failing for you?
0newguy11y
Maybe because there is always a clear line? I go from meeting to kissing quite fast, and from kissing to being in my bedroom also quite fast, so there is no small progression, it's meeting, kissing, then we end up at a sex-appropriate place and I go trough it, but I'm incredibly anxious.
2MixedNuts11y
By "quite fast" do we mean a few hours, or a few dates? If the latter: You are in fact allowed not to have sex on the first date, or the first time they're in your bedroom. You can go as far as you're comfortable with and no further - and know where you'll stop in advance, so you're not anxious beforehand, and then go a little further on subsequent dates. Is your anxiety tied to specific acts, or to sex itself? Does it help if I point out that the boundaries of what counts as sex are very blurry, and do your anxieties change if you change what you think of as sex?
2newguy11y
3 meetings, wouldn't call them dates. I understand that, but it somehow makes me feel bad to have them there and ready and that I'm the one that actually also wants to but somehow/for some reason can't. Just first-time sex as in intercourse. Well, in my mind sex = intercourse [as in penis in vagina], everything else is "fooling around". [Not debating definitions, just saying how it feels to me]. I don't know I need to test it, but that might be useful to try, to try to think of sex as being something else.
4MixedNuts11y
Sounds like your problems could cancel out. If you decline intercourse but "fool around" a lot, they're unlikely to be too unhappy about it.

Does anyone have any real-world, object-level examples of degenerate cases)?

I think degeneracy has some mileage in terms of explaining certain types of category error, (eg.

So far, the only example I've come up with is a platform pass at a train station, which is a degenerate case of a train ticket. It gets you on the platform and lets you travel a certain number of stops (zero) down the train line.

Serious-ish answers: The degenerate case of dieting is when you increase your calorie intake by zero. (Also applies to government budgets, although it's then usually referred to as a "cut".) The degenerate case of tax reform is to pass no new laws. The degenerate case of keeping kosher (also halal, fasting, giving things up for Lent) is to eat anything you like. The degenerate case of a slippery-slope argument is to say "If we do X, X will follow, and then we'll be sure to have X, from which we'll certainly get X". (That is, this argument is the limit as epsilon goes to zero of the argument X -> X+epsilon -> X+2 epsilon...). Mainly in jest: Dictatorship considered as a degenerate case of democracy: One Man, One Vote - he is The Man, he has The Vote. Conversely, democracy considered, Moldbug-style, as the degenerate case of dictatorship: Each of N citizens has 1/N of the powers of the dictator.

True. It's harder to fake rationality than it is to fake the things that matter today, however (say, piety). And given that the sanity waterline has increased enough that "rational" is one of the most desirable traits for somebody to have, fake signaling should be much harder to execute.

Faking rationality would be rather easy: Criticize everything which is not generally accepted and always find biases in people you disagree with (and since they are humans, you always find some). When "rationality" becomes a popular word, you can get many followers by doing this. Here I assume that the popularity of the word "rationality" will come before there are millions of x-rationalists to provide feedback against wannabe rationalists. It would be enough if some political movement decided to use this word as their applause light.

The community here is heavily centered around Eliezer. I guess if someone started promoting some kind of fake rationality here, sooner or later they would get into conflict with Eliezer, and then most likely lose the support of the community. For another wannabe rationalist guru it would be better to start their own website, not interact with people on LW, but start recruiting somewhere else, until they have greater user base than LW. At the moment their users notice LW, all they have to do is: 1) publish a few articles about cults and mindkilling, to prime their readers, and 2) publish a critique of LW with hyperlinks to all currently existing critical sources. The proper framing would be that LW is a fringe group which uses "rationality" as applause lights, but fails horribly (insert a lot of quotations and hyperlinks here), and discussing them is really low-status. It would help if the new rationalist website had a more professional design, and emphasised its compatibility with mainstream science, e.g. by linking to high-status scientific institutions, and sometimes writing completely uncontroversial articles about what those institutions do. In other words, the new website should be optimized to get 100% approval of the RationalWiki community. (For someone trying to do this, becoming a trusted member of RationalWiki community could be a good starting point.)

I'm busy having pretty much every function of RW come my way, in a Ponder Stibbons-like manner, so if you can tell me where the money is in this I'll see what I can come up with. (So far I've started a blog with no ads. This may not be the way to fame and fortune.)
1gwern11y
The money or lack thereof doesn't matter, since RW is obviously not an implementation of Villam's proposed strategy: it fails on the ugliness with its stock MediaWiki appearance, has too broad a remit, and like El Reg it shoots itself in the foot with its oh-so-hilarious-not! sense of humor (I dislike reading it even on pages completely unrelated to LW). It may be successful in its niche, but its niche is essentially the same niche as /r/atheism or Richard Dawkins - mockery of the enemy leavened with some facts and references. If - purely hypothetically speaking here, of course - one wished to discredit LW by making the respective RW article as negative as possible, I would expect it to do real damage. But not be any sort of fatal takedown that set a mainstream tone or gave a general population its marching orders, along the lines of Shermer's 'cryonics is a scam because frozen strawberries' or Gould's Mismeasure of Man's 'IQ is racist, involved researchers like Merton faked the data because they are racist, and it caused the Holocaust too'.

2David_Gerard11y
Accomplishment is a start. Do the claims match the observable results?

Yeah, because true rationality is going to be supporting something like cryonics that you personally believe in.
0NancyLebovitz11y
I can't see any good general solutions. People are limited to their own judgement about whether something which purports to be selling rationality actually makes sense. You take your chances with whether martial arts and yoga classes are useful and safe. LW et al. does have first mover advantage and hopefully some prestige as a result, and I'm hoping that that resources for the general public will be developed here. On the other hand, taking sufficient care to develop workshops which actually work takes time-- and that's workshops for people whose intelligence level is similar to that of the people putting on the workshops. If we assume that rationalists should win, even over fake rationalists, then maybe we should leave the possibility open that rationalists who are actually in the situation of competing with fake rationalists should be in a better position to find solutions because they'll know more than we do now.
0Viliam_Bur11y
I also don't have a solution besides reminding the rationalists that we run on corrupted hardware, and the strong feeling of "these people around me are idiots, I could do it hundred times better" is an evolutionary adaptation for situations when there are many resources and no significant external enemy. (And by the way, this could explain a lot of individualism our society has these days.) We had a few people here who got offended e.g. by Eliezer's certainty about quantum physics, and tried to split, and failed. So perhaps the risk is actually small. Fake rationalists may be prone to self-sabotage. The proverbial valley of the bad rationality surrounding the castle of rationality can make being a half-rationalist even worse than being a non-rationalist. So the rationalists may have a hard time fighting pure superstition, but the half-rationalists will just conveniently destroy themselves. The first mover advantage works best if all players are using the same strategy. But sometimes the new player can learn from older players' mistakes, and does not have to pay the costs. (Google wasn't the first search engine; Facebook wasn't the first social network; MS Windows wasn't the first operating system with graphical interface.) The second player could learn from LW's bad PR. But it is likely that being completely irrational would be even more profitable for them, if profit would be the main goal.

Does anybody on here use at-home EEG monitors? (Something like http://www.emotiv.com/store/hardware/epoc-bci-eeg/developer-neuroheadset/ although that one looks rather expensive)

Hm. Do you know of any resources on how to use EEG information to improve your thought processes? (I'm highly tempted to put some of my tax return to trying it out; partially for improvement purposes, partially because I'm curious how much is going on inside my mind I'm unaware of.)
4gwern11y
Anything labeled 'neurofeedback' seems like a good place to start. I presently have few ideas about how to use it, aside from seeing if it's a good way to quantify meditation quality and hence have more direction in meditation than random books and 'well, it seems to be helping a little'.
2Zaine11y
EEG machines measure frequency of neuronal firing in the cortex. The greater the frequency, the more asynchronous the firing and thus the more active the brain. Learning how to read EEG output requires training, but there might be computer programs for that. To use the machine effectively, identify an activity for which you'd like to measure your brain waves, exempli gratia: Measure degrees of neuronal firing asynchrony during work periods (pomodoros) - useful for calibrating an accurate feeling of focus; measure success of meditation (gamma wave output), as gwern noted; measure which break activities actually induce a relaxed state; and of course check quality of sleep.

Cal Newport and Scott H. Young are collobarating to form a start deliberate practice course by email. Here's an excerpt from on Cal's emails to inquiring people:

The goal of the course is simple: to teach you how to apply the principles of deliberate practice to become a stand out in your job.

Errh

On an uncharitable reading, this sounds like two wide-eyed broscientist prophets who found The One Right Way To Have A Successful Career (because by doing this their career got successful, of course), and are now preaching The Good Word by running an uncontrolled, unblinded experiment for which you pay 100$ just to be one of the lucky test subjects.

Note that this is from someone who's never heard of "Cal Newport" or "Scott H. Young" before now, or perhaps just doesn't recognize the names. The facts that they've sold popular books with "get better" in the description and that they are socially-recognized as scientists are rather impressive, but doesn't substantially raise my priors of this working or not.

So if you've already tried some of their advice in enough quantity that your updated belief that any given advice from them will work is high enough and stable enough, this seems more than worth 100$.

Just the possible monetary benefits probably outweigh the upfront costs if it works, and even without that, depending on the kind of career you're in, the VoI and RoI here might be quite high, so depending on one's career situation this might need only a 30% to 50% probability of being useful for it to be worth the time and money.

In a few places — possibly here! — I've recently seen people refer to governments as being agents, in an economic or optimizing sense. But when I reflect on the idea that humans are only kinda-sorta agents, it seems obvious to me that organizations generally are not. (And governments are a sort of organization.)

Amanda Knox and evolutionary psychology - two of LessWrong's favorite topics, together in one news article / opinion piece.

The author explains the anti-Knox reaction as essentially a spandrel of an ev. psych reaction. Money quote:

In our evolutionary past, small groups of hunter-gatherers needed enforcers, individuals who took it upon themselves to punish slackers and transgressors to maintain group cohesion. We evolved this way. As a result, some people are born to be punishers. They are hard-wired for it.

I'm skeptical of the ev. psych because it... (read more)

7komponisto11y
The phenomenon of altruistic punishment itself is apparently not just a matter of speculation. Another quote from Preston's piece: He links to this PNAS paper which uses a computer simulation to model the evolution of altruistic punishment. (I haven't looked at it in detail.) Whatever the explanation for their behavior (and it really cries out for one), the anti-Knox people are truly disturbing, and their existence has taught me some very unpleasant but important lessons about Homo sapiens. (EDIT: One of them, incidentally, is a mathematician who has written a book about the misuse of mathematics in trials -- one of whose chapters argues, in a highly misleading and even disingenuous manner, that the acquittal of Knox and Sollecito represents such an instance.)
2TimS11y
Skimming the PNAS paper, it appears that the conclusion is that evolved group co-operation is not mathematically stable without evolved altruistic punishment. I.e. populations with only evolved co-operation drift towards populations without any group focused evolved traits, but altruistic punishment seems to exclude enough defectors that evolved co-operation maintained frequency in the population. Which makes sense, but I'm nowhere close to qualified to judge the quality of the paper or its implications for evolutionary theory.

I am aware that there have been several discussions over to what extent x-rationality translates to actual improved outcomes, at least outside of certain very hard problems like metaethics. It seems to me that one of the best ways to translate epistemic rationality directly into actual utility is through financial investment/speculation, and so this would be a good subject for discussion (I assume it probably has been discussed before, but I've read most of this website and cannot remember any in depth-thread about this, except for the mention of markets b...

Bring some women to the team. (Yeah, that just changes the problem to a harder one: Where to find enough women rationalists interested in finance?) Or have multiple men on the team, and let them decide through some kind of voting. This would work only if their testosterone level fluctuations are uncorrelated. You could do some things to prevent that, e.g. forbid them to meet in person, and make their coordination as impersonal as possible, to prevent them from making each other angry. This sounds like a huge complication to compensate for a single source of bias, so it needs some measurement. If this could help the team make millions, perhaps it is worth doing. Maybe irrationality could be modelled as just another cost of participating in the market. There are many kinds of costs which one has to pay to participate in the market. You pay for advertising, for transferring goods from the place they are produced to the customer, etc. Your own body must be fed and clothed. Irrationality is a cost of using your brain. If you would transfer your cargo by a ship, especially a few centuries ago, you would have to accept that some part of your ships will sink. And yet, you could make a profit, on average. Similarly, if you use human brain to plan your business, you have to accept that some part of your plans will fail. The profit can still be possible, on average.
2NancyLebovitz11y
This is just from memory, but I think testosterone levels aren't (just?) about anger. Again from memory, testosterone goes up from winning, so the problem is overconfidence from previous victories.

I'm afraid that is opposite to a solution to this particular problem. Even neglecting the fluctuation in women's testosterone levels and considering only the stereotypical androgenic behaviour of the males this can be expected to (if anything) increase the risk taking behaviours of the kind warned against here. Adding females to an already aggressive male group gives them prospective mates to show off to. The linked to article mentions observations of this. (There may be other reasons to bring more women onto your professional trading team. Just not this one.)

I wonder if many people are putting off buying a bitcoin to hang onto, due more to trivial inconvenience than calculation of expected value. There's a bit of work involved in buying bitcoins, either getting your funds into mtgox or finding someone willing to accept paypal/other convenient internet money sources.

8Qiaochu_Yuan11y
What if we're putting off buying a bitcoin because we, uh, don't want to?
3lsparrish11y
Ok... Well... If that's the case, and if you can tell me why you feel that way, I might have a response that would modify your preference. Then again, your reasoning might modify my own preference. Cryptic non-argument isn't particularly interesting, or helpful for coming to an Aumann Agreement. Edit: Here is my response.

1) I am not at all convinced that investing in bitcoins is positive expected value, 2) they seem high-variance and I'm wary about increasing the variance of my money too much, 3) I am not a domain expert in finance and would strongly prefer to learn more about finance in general before making investment decisions of any kind, and 4) your initial comment rubbed me the wrong way because it took as a standing assumption that bitcoins are obviously a sensible investment and didn't take into account the possibility that this isn't a universally shared opinion. (Your initial follow-up comment read to me like "okay, then you're obviously an idiot," and that also rubbed me the wrong way.)

If the bitcoin situation is so clear to you, I would appreciate a Discussion post making the case for bitcoin investment in more detail.

2RomeoStevens11y
regulatory uncertainty swamps any quantitative analysis I think.
5Kaj_Sotala11y
The standard advice is that normal people should never try to beat the market by picking any single investment, but rather put their money in index funds. The best publicly available information is already considered to be reflected in the current prices: if you recommend in buying a particular investment, that implies that you have knowledge that the best traders currently on the market do not have. As a friend commented: So if you think that people should be buying Bitcoins, it's up to you to explain why the standard wisdom on investment is wrong in this case. (For what it's worth, personally I do own Bitcoins, but I view it as a form of geek gambling, not investment. It's fun watching your coins lose 60% in value and go up 40% from that, all within a matter of a few days.)
5RomeoStevens11y
Bitcoins are more like investing in a startup. The plausible scenarios to bitcoins netting you a return commensurate with the risk involve it disrupting several 100 billion+ markets (paypal, western union). I think investing in startups that have plausible paths towards such disruptions are worthy of a small portion of your portfolio.

At the level of buying just one bitcoin the convenience is more than trivial. Even just in the financial burden of the bank transfers changes the expected value calculation quite a bit (allthough the cost seems to be reducing somewhat).
0[anonymous]11y
In case anyone has difficulty with the convenience factor: I have four bitcoins that I bought for about 100 USD. Currently MtGox is at under 80 USD. As long as it remains at or below that rate, I am willing to sell these at 100 USD via paypal. It's not a great price but it is much more convenient to pay by paypal than the other methods available to buy bitcoins. * Only lesswrongers with decent karma and posting history qualify. * The intended purpose is for you to hold them long-term against the off chance that it becomes a mainstream currency in the long term. Please hold them for at least a year. * They can be converted to paper wallet form, which I will do for you if you opt to trust me ( because as far as I know this implies I would have access unless/until I delete the wallet) and send it to you by snail-mail. * I will most likely be using the proceeds to buy more via IRC.

That's the one. I misremembered and thought it was an LW post.

I heard a speaker claim that the frequency of names in the Gospels matches the list of most popular names in the time and place they are set, not the time and place they are accepted to have been written in. I hadn't heard this argument before and couldn't think of a refutation. Assuming his facts are accurate, is this a problem?

8gwern11y
A problem for what? It's not much evidence for a historical-realist-literalist viewpoint, because the usual mythicist or less-literal theories generally believe that the original stories would have gotten started around the time they are set in, and so could be expected to mimick the name distribution of the setting, and keep the mimicking (while warping and evolving in many other ways) until such time as they are compiled by a scribe and set down into a textual form. Few think that Gospels were made up out of whole cloth in 300 AD and hence having versimiltude (names matching 30s AD) is a surprising feature and evidence against the whole-cloth theory. Generally, both believers and mythicists think some stories and myths and sayings and parables got started in the 30s+ AD and passed down and eventually written down, possibly generations later, at various points like the 90s AD; what they disagree on is how much the oral transmission and disciples affected things and what the origin was.

Toying around with the Kelly criterion I get that the amount I should spend on insurance increases with my income though my intuition says that the higher your income is the less you should insure. Can someone less confused about the Kelly criterion provide some kind of calculation?

For anyone asking, I wondered if, given income and savings rate how much should be invested in bonds, stocks, etc. and how much should be put into insurance, e.g. health, fire, car, etc. from a purely monetary perspective.

4RolfAndreassen11y
The Kelly criterion returns a fraction of your bankroll; it follows that for any (positive-expected-value) bet whatsoever, it will advise you to increase your bet linearly in your income. Could this be the problem, or have you already taken that into account? That aside, I'm slightly confused about how you can use the Kelly criterion in this case. Insurance must necessarily have negative expected value for the buyer, or the insurer makes no profit. So Kelly should be advising you not to buy any. How are you setting up the problem?
3Metus11y
Well that is exactly the point. It confuses me that the richer I am the more insurance I should buy, though the richer I am the more I am able to compensate the risk in not buying any insurance. Yes and no. The insurer makes only a profit if the total cost of insurance is lower than the expected value of the case with no insurance. What you pay the insurer for is that the insurer takes on a risk you yourself are not able to survive (financially), that is catastrophically high costs of medical procedures, liabilities or similar. It is easily possible for the average Joe to foot the bill if he breaks a $5 mug but it would be catastrophic for him if he runs into an oil tank and has to foot the $10,000,000 bill to clean up the environment. (This example is not made up but actually happened around here.) It is here where my intuition says that the richer you are, the less insurance you need. I could also argue that if it was the other way around, that you should insure more the richer you are, insurance couldn't exist, seeing as the insurer is the one who should buy insurance from the poor! You can use the Kelly criterion in any case, either negative or positive expected value. In the case of negative value it just tells you to take the other side of the bet or to pay to avoid the bet. The latter is exactly what insurance is. I model insurance from the point of view of the buyer. In any given time frame, I can avoid the insurance case with probability q, saving the cost of insurance b. Or I could lose and have to pay a with the probability p = 1-q. This is the case of not buying insurance, though it is available. So if f = p/a - q/a is negative I should insure, if f is positive, I should take the risk. This follows my intuition insofar that catastrophic but improbable risk (very high a, very low p) should be insured but not probable and cheap liabilities (high p, low a). The trick is now that f is actually the fraction of my bankroll I have to invest. So the richer
6Richard_Kennaway11y
The Kelly formula assumes that you can bet any amount you like, but there are only so many things worth insuring against. Once those are covered, there is no opportunity to spend more, even if you're still below what the formula says. In addition, what is a catastrophic loss, hence worth insuring against, varies with wealth. If the risks that you actually face scale linearly with your wealth, then so should your expenditure on insurance. But if having ten times the wealth, your taste were only to live in twice as expensive a house, drive twice as expensive a car, etc. then this will not be the case. You will run out of insurance opportunities even faster than when you were poorer. At the Jobs or Gates level of wealth, there are essentially no insurable catastrophes. Anything big enough to wipe out your fortune would also wipe out the insurance company.
0Metus11y
Your reply provides part of the missing piece. Given that I am over some kind of absolute measure of poverty, empirically having twice as much disposable income won't translate into twice as much insurable assets. This limits the portion of bankroll that can be spent for insurance. Also, Kelly assumed unlitimited offer of bets which is not that far from the truth. Theoretically I can ask the insurer to give twice the payout for twice the cost of insurance. And still, your answer doesn't quite answer my original question. I asked for given (monthly) income, savings rate and maybe wealth, what is a optimal allocation of insurance and investments, e.g. bonds or equity? And even if assuming that I keep my current assets but double my income and wealth, Kelly still says to buy insurance, though you admit that anything Gates would want to insure against would ruin the insurer, but my intuition still says that Gates does not insure anything that I would, like a car, house or health costs.
3RolfAndreassen11y
Perhaps the problem lies in the dichotomy "buy insurance" versus "do not buy". It seems to me that you have, in fact, got three, not two, options: a) Buy insurance from someone else b) Spend the money c) Save the money, in effect buying insurance from yourself. I think option c) is showing up in your analysis as "do not buy insurance", which should be reserved for b). You are no doubt correct that Gates does not buy car insurance (unless perhaps he is forced to by law), but that does not mean he is not insured. In effect he is acting as his own insurer, pocketing the profit. It seems to me, then, that Kelly is telling you that the richer you are, the more you should set aside for emergencies, which seems to make sense; but it cannot distinguish between self-insurance and buying an insurance policy.
2Metus11y
So you say that if Kelly says to buy insurance for $300 if the insurance costs $100 I should not buy the police but set aside $300 in case of emergency?
2RolfAndreassen11y
Insurance whose payout is only three times the policy cost should rather be classified as a scam. More generally, I think the strategy would be thus: Kelly tells you to take some amount of money and spend it on insurance. If that amount is enough to cover the payout of the insurance policy, then you should not pay the premium; instead you should put the money in savings and enjoy the interest payments. Only if the amount Kelly assigns to insurance is too small to cover the payout should you consider paying the premium.

Depends on the cost of the risk, no? For a first generation XBox 360, paying half the price for a new replacement is not obviously a bad deal...
2RolfAndreassen11y
Ok, in that case it's rather the Xbox that is the scam, but I stand by the use of the word. If that sort of insurance is a good deal, you're being screwed over somewhere. :)
0gwern11y
I wouldn't say that; as always, the question is whether the good is +EV and the best marginal use of your money. If the console costs $3 and insurance costs $1 and there's a >33% chance the console will break and you'll use the insurance, given how much fun you can have with an Xbox is that really a scam? I wouldn't say so. In practice the insurance that you can buy is too limited and the odds too bad to actually make it a good deal; I did some basic analysis of the issue at http://www.gwern.net/Console%20Insurance and you're better off self-insuring, at least with post-second-generation Xbox 360s (the numbers look really bad for the first-generation but hard sources are hard to come by).
1Richard_Kennaway11y
You can ask, but your insurer will decline. You can only insure your house for what it's worth.
0Metus11y
Maybe in that case. In the case of life insurance I have practically unlimited options. Whether I insure for $1M or $1k in case of my death is up to me.
0Richard_Kennaway11y
Term life insurance, which pays out nothing if you live beyond the term, is like other insurance: it is only worth buying to protect against some specific risk (e.g. mortgage payments) consequent on an early death. Life assurance is different, in that the event insured against is certain to happen. That is why it is called assurance: assuredly, you will die. As such, it is primarily an investment, together with an insurance component that guarantees a payout even if you die prematurely. As an investment, you can put as much as you like into it, but if your heirs will not be financially stricken if you die early, you -- or rather, they -- do not need the insurance part.
1aleksiL11y
You have it backwards. The bet you need to look at is the risk you're insuring against, not the insurance transaction. Every day you're betting that your house won't burn down today. You're very likely to win but you're not making much of a profit when you do. What fraction of your bankroll is your house worth, how likely is it to survive the day and how much will you make when it does? That's what you need to apply the Kelly criterion to.

Here's something I think should exist, but don't know if it does: a list of interesting mental / neurological disorders, referencing the subjects they have bearing on.

Does this exist already?

0Qiaochu_Yuan11y
What do you mean by "interesting" and "subjects"?
4sixes_and_sevens11y
By "interesting" I mean "of interest to the Less Wrong community", specifically because they provide insight into common failure modes of cognition, and by extension, cognition itself. By "subjects", I mean the topics of inquiry they provide insight into. Here is an example that should hopefully pin down what I am talking about. I personally have a mental catalogue of such disorders, and given their prevalence in discussion around here I suspect a number of other people do as well. It would be nice if we all had one big catalogue.

So, I have a primitive system for keeping track of my weight: I weigh myself daily and put the number in a log file. Every so often I make a plot. Here is the current one. I have been diligent about writing down the numbers, but I have not made the plot for at least a year, so while I was aware that I'm heavier now than during last summer, I had no idea of the visual impact of that weight loss and regain. My immediate thought: Now what the devil was I doing in May of 2012, and can I repeat it this year and avoid whatever happened in July-August?

0Qiaochu_Yuan11y

3RolfAndreassen11y
Convenient, but a) I like having things in a text file that I can open with a flick of the keyboard on the same system I'm working on anyway b) Making my own plot, I have full control of the formatting, plus I can do things like fit trends over given periods, mark out particular dates, or otherwise customise c) I dread the day when some overeager Google popup tells me that "It looks like you're trying to control your weight! Would you like me to show you some weight-loss products?" (At least one of these items not intended seriously).
0DaFranker11y
You mean (a), right? 'caus "flick of the keyboard" is kind of funny, but setting that up for a particular text file sounds awfully... unworkable. (point (c) is not nearly as unrealistic as it might seem at first - they're pretty much already there to some extent)
3RolfAndreassen11y
Oh, I absolutely believe that Google will tell you about weight-loss products if they detect you tracking a number that looks reasonable for a human weight in pounds, and that they have an algorithm capable of doing that. It's the overeager popup with the near-quote of Clippy (the original Microsoft version, not our friendly local Clippy who, while he might want to turn you into your component atoms for reuse, is at least not unbearably upbeat about it) that's unrealistic. "Flick of the fingers on the keyboard", then: From writing here it is Windows-Tab, Windows-1, C-x b, w-e-i-Tab, Enter. If the file wasn't already open in emacs, replace C-x b with C-x C-f.

If you can, buy a machine that measures your body fat percentage as well (bioelectrical impedance) - it's a more meaningful statistic. If you're measuring once per month, under consistent hydration and bowel volume, it could be pretty convenient.

North Korea is threatening to start a nuclear war. The rest of the world seems to be dismissing this threat, claiming it's being done for domestic political reasons. It's true that North Korea has in the past made what have turned out to be false threats, and the North Korean leadership would almost certainly be made much worse off if they started an all out war.

As someone who studies lots of history while often thinking, "how could they have been this stupid didn't they know what would happen?", I thought it useful to frame the question this way. Hitler's professed intentions were not taken seriously by many.

Hitler's professed intentions were not taken seriously by many.

Taken seriously... when? Back when he was a crazy failed artist imprisoned after a beer hall putsch, sure; up to the mid-1930s people took him seriously but were more interested in accommodationism. After he took Austria, I imagine pretty much everyone started taking him seriously, with Chamberlain conceding Czechoslovakia but then deciding to go to war if Poland was invaded (hardly a decision to make if you didn't take the possibilities seriously). Which it then was. And after that...

If we were to analogize North Korea to Hitler's career, we're not at the conquest of France, or Poland, or Czechoslovakia; we're at maybe breaking treaties & remilitarizing the Rhineland in 1936 (Un claiming to abandon the cease-fire and closing down Kaesŏng).


One thing that hopefully the future historians will notice is that when North Korea attacks, it doesn't give warnings. There were no warnings or buildups of tension or propaganda crescendos before bombing & hijacking & kidnapping of Korean airliners, the DMZ ax murders, the commando assault on the Blue House, the sinking of the Cheonan, kidnapping Korean or Japanese c...

Certainly the consequences of us being wrong are bad, but that isn't necessarily enough to outweigh the presumably low prior probability that we're wrong.

There is an issue of ability vs. intention, no matter whether the North Korean leadership wants to destroy the US or South Korea they don't have the ability to do any major harm. The real fear is that the regime collapses and we're left with a massive humanitarian crisis.

1shminux11y
Maybe a slow and controlled introduction of free enterprise, Deng Xiaoping-style, while maintaining a tight grip on political freedoms, at least until the economy recovers somewhat, could soften it. Incidentally, this is apparently the direction Kim Jong-un is carefully steering towards. Admittedly, slacklining seems like a child's play compared to the perils he'd have to go through to land softly.

0[anonymous]11y
I was talking about this with a friend of mine, and it does seem like there is no outcome that's not going to be hugely, hideously expensive. The costs of a war are obviously high - even if they don't/can't use nukes, they could knock Seoul right out of the global economy. But even if its peaceful you'd have this tidal wave of refugees into China and the South, and South Korea will be paying reunification costs for at least the next decade or so. You can sort of see why SK and China are willing to pay to keep the status quo, and screw the starving millions.
3gwern11y
Far longer than that. (West) Germany is apparently still effectively subsidizing (former) East Germany, more than 2 decades after unification - and I have read that West & East Germany were much closer in terms of development than North & South Korea are now. For the total costs of reunification, 'trillions' is probably the right order of magnitude to be looking at (even though it would eventually more than pay for itself, never mind the moral dimension).
1[anonymous]11y
I quite agree, on both parts. 25 million new consumers, catch-up growth, road networks from Seoul to Beijing, navigable waters, less political risk premium, etc. It's a gloomy picture though. A coup seems unlikely (given the Kim-religion) and it'll probably be 2050-70 until Jong-un dies. I've got two hopes: the recent provocation is aimed at a domestic audience, and once he's proved himself he'll pull a Burma; or the international community doesn't blink and resume aid, forcing them into some sort of opening. Not very high hopes though.
4gwern11y
To expand: a massive burst of cheap labor, a peace dividend in winding down both militaries (on top of the reduction in risk premium) such as closing down military bases taking valuable Seoul-area real estate, and access to all NK's mineral and natural resources.
0drethelin11y
I had a little dream scenario in my head when Jong Il died that Jong Un would have been secretly rebellious and reasonable and start implementing better policy bit by bit, but that clearly didn't happen. My hope is that whoever actually has their hands on the buttons in charge of the bombs and military is more reasonable than Jong-Un, and that he gets taken out either by us or by someone close to him who has a more accurate view of reality. At this point, the international rhetoric would immediately start being toned down, and the de facto government could start making announcements about the world changing its mind or something to smooth over increased cooperation and peace and foreign aid.

I would suppose that some of them do. I would further suppose that it's not actually a bad idea, if the pregnancy was reasonably advanced.

To the extent that funerals are a grief-coping mechanism, people probably should hold them for miscarriages.

My favorite argument about abortion is to point out that if the soul enters the body at conception, as identical twins split after conception, this logically implies that one twin has no soul, and thus is evil. The evil twin can usually be identified by sporting a goatee.

That's based on the unstated but incorrect premise that souls are indivisible and only distributed in whole number amounts. Anyone who's spent time around identical twins can tell that they only have half a soul each.

I would like to point out that my argument is against 'the soul enters the body at conception' not 'there exists a soul'. If souls twin, then this provides an example where the soul enters the body after conception, proving my point. There are plenty of beliefs in souls that do not require them entering the body at conception. Some Hindus would say that the body, like all material objects, is maya, or illusion, and only consciousness exists, and thus the question 'does the soul enter the body at conception?' is meaningless. I wouldn't say I agree with this point of view, but its a lot more reasonable.

This article is fascinating: http://io9.com/5963263/how-nasa-will-build-its-very-first-warp-drive

A NASA physicist called Harold White suggests that if he tweaks the design of an 'Alcubierre Drive', extremely fast space travel is possible. It bends spacetime around itself, apparently. I don't know enough about physics to be able to call 'shenanigans' - what do other people think?

1kpreid11y
IANAPhysicist, but what seem to me to be the main points: * The Wikipedia article seems to be a fairly good description of problems. Briefly: The warp bubble is a possible state of the universe solely considering the equations of general relativity. We don't yet know whether it is compatible with the rest of physics. * The Alcubierre drive requires a region of space with negative energy density; we don't know any way to produce this, but if there is it would involve some currently-unknown form of matter (which is referred to as “exotic matter”, which is just a catch-all label, not something specific). * The work described in the article consists of two things: 1. Refining the possible state to have less extreme requirements while still being FTL. 2. Conducting experiments which study an, ah, extremely sub-FTL state which is similar in some sense to the warp bubble. This part seems to me to have a high chance of being just more confirmation of what we already know about general relativity.
