I think your point about less information per screen identifies what has been bothering me. It makes it much harder to skim or to refer back to previous paragraphs.

The "Daily" page seems to be the one that is most useful to regular users (it's the one I bookmarked), but it's relatively hidden. I think it should be linked directly on the top navbar or somewhere else on the front page instead of hidden inside the hamburger menu in the navbar.

Very useful indeed. Bookmarked. Thanks!

Does anybody have recommendations for video lecture series? Any topic.

4Screwtape
Crash Course on youtube has a variety of ~10 minute videos on a whole bunch of topics- I haven't watched most of the topics, but History and Literature are pretty decent. The length hurts in a lot of places, but I think it does a good job given that constraint and I'll admit I'm a lot more likely to "one more video" my way through a dozen of those than I am to sit down for a two hour documentary on the Vietnam War or The Great Gatsby, even if I'd feel like I was getting a more in-depth education out of the latter.

But why is it a piece of evidence pointing to greater than 80% instead of 80%?

0Lumifer
Basically it depends on the source of uncertainty. If all the uncertainty is in the random variable being modeled (as it is in the die example), adding more forecasts (or models) changes nothing -- you still have the same uncertainty. However if part of the uncertainty is in the model itself -- there is some model error -- then you can reduce this model error by combining different (ideally, independent) models. Imaging a forecast which says: I think A will win, but I'm uncertain so I will say 80% to A and 20% to B. And there is another, different forecast which says the same thing. If you combine the two, your probability of A should be higher than 80%.

I still don't see the difference.

Are you saying that if many forecasters predict that something has an 80% probability of happening and they all use different methodologies, I should expect it to happen with greater than 80% probability? Why?

0Lumifer
Use the simple Bayesian updating on the evidence. A new, different forecast is a new piece of evidence.

That would not be reasonable if we were talking about something like a prediction of whether a 5-sided die would come up with the number 1. Why are polls any different?

0Lumifer
Because the polls are supposed to be different and all forecasts about a 5-sided die are the same. Imagine yourself collecting forecasts and updating on them. With the die, many forecasts will not change your expected probabilities because these forecasts are basically all the same. When you hear another one, the amount of information you have doesn't change. That is not (supposed to be) the case with polls. If one forecast says 80% vs 20% and another, different forecast using, say, a different methodology or different sources, also says 80% vs 20%, your expected probabilities should be >80% vs <20%, how much more and less depends on how much do you believe the forecasts are correlated. If you hear many different forecasts saying 80:20, you expectation should not be 80:20.

Is the example about an academic article on hyper computation real?

Anybody have recommendations of a site with good summaries of the best/most actionable parts from self-help books? I've found Derek Sivers' book summaries useful recently and am looking for similar resources. I find that most self-help books are 10 times as long as they really need to be, so these summaries are really nice, and let me know whether it may be worth it to read the whole book.

4ChristianKl
I frequently hear people saying that self-help books are too long but I don't think that's really true. Changing deep patterns about how to deal with situations is seldomly made by reading a short summary of a position.

Robin Hanson's "The Age of Em" is a book about this sort of thing.

Anyone have recommendations of fiction along the lines of Worm and HPMOR that are also very long (>400k words)?

1gjm
You probably already know this, but the author of Worm has written another long (though not so long) serial called Pact and is in the middle of another called Twig. If you enjoyed Worm and haven't read those yet, you might give them a try.
0TheAltar
There's a subreddit for rational/rationalist fiction that may interest you or have a longer list of suggestions than here. I think the subreddit was www.reddit.com/r/rational
2drethelin
Harry Potter and the Natural 20 has a lot of characters optimizing in interesting ways in response to the constraints of their universe, but their universe's laws are a lot less realistic than Worm or HPMOR. The Ethshar books by Lawrence Watt-Evans are not one coherent story but there are a lot of books set in the same world. Miles Vorkosigan has the whole "cunning main character thinks outside the box to beat impossible odds" dynamic and there are a bunch of books that follow him and his life, although the fact that he ages throughout them gives them a pretty different feel than the chronologically much shorter timespan of HPMOR.

Are there any specific kinds of dancing lessons you'd recommend over others?

1Viliam
My personal preference is: Waltz (+Viennese Waltz), Quickstep, Jive, Cha-cha, and Salsa. With this set you have all bases covered. There is the "diminishing returns" aspect in dancing too. Learn five basic figures from each dance I mentioned above and you are the king; already a better dancer than 90% of men around you in a random situation. Also at that moment you will know enough to make your own decisions. You need Waltz for 3/4 music, there is no other choice; and in social situations 3/4 music will happen. Quickstep, Jive, Cha-cha and Salsa are quite flexible; for any 4/4 or 2/4 music one or more of them will fit; if there is a lot of space go for Quickstep or Cha-cha, if there is less space Jive or Salsa will do. (Not sure which one? Choose randomly; and if it feels too slow or too quick, try another.) An important part is learning to lead your partner. The rule of thumb is that your partner cares about moving her feet properly, while you gently push/pull/rotate her body at specific moments. If your timing is good and the signals are clear, the moves will come "natural" to her even if she is a total beginner. (How well the couple dances depends mostly on how well the man dances. Which makes it a great opportunity for signalling your skills.) So after you learn the steps in the classroom, as a next lesson try alternating them randomly with only nonverbal communication. Learning this not only makes you a better dancer, but it extends your opportunities in real life, when your partner either didn't attend any dancing lessons, or she learned different dances than you did.

Not be "low-skilled", obviously.

I think the standard answer is "acquire capital." Figuring out which tasks are AI hard and then specializing in those is another possibility.

You could save up money for a few months then move to a country with a very cheap cost of living and live off your savings.

In a reddit AMA a couple of days ago, someone asked Sam Altman (president of Y Combinator) "How do you think we can best prepare ourselves for the advance of AI in the future? Have you and Elon Musk discussed this topic, by chance?" He replied:

Elon and I have discussed this many, many times. It's one of the things I think about most. Have some news coming here in a few months...

Any guesses on the news?

Tutoring? Put up flyers and sign up for wyzant (they take 40% at first, going down to 20% after you log many hours with them, which really sucks, but they're the only popular online marketplace for tutors).

Long shot again:

Any LW NYCers have a room available for <$1,000 per month that I (a friendly self-employed 23-year-old male) might be able to move into within a week or two? Or leads on a 1br/studio for <$1400? I could also go a bit above those prices if necessary.

PM me if so and I'll send more details about myself. I'm also staying with some friends in NYC right now so we could meet up anytime.

I recommend you read The Motivation Hacker for techniques to get yourself to do what you know you should be doing, but can't bring yourself to do. I especially recommend Beeminder, especially this approach to using it.

If you want to make games, start doing it now. It's entirely possible for a single person to make great indie games. Working on that would also build skills that are useful for all 4 of the preferred careers you named.

It's okay if you find CS classes boring; the real test is whether you find working on real projects (such as your own indie games) boring.

Having lots of portfolio pieces will also help with finding a job.

2gothgirl420666
Yeah, I am already working on my own games. I worked on one for two hours earlier today. My eternal problem is that I can only think big. When I was a little kid I would constantly envision these 1000-page epics I was going to write, type about seven pages or so, and then get bored and start a new project the next week. I constantly try to come up with ideas for small, fun little games that I could realistically make by myself in a few months but I can never come up with anything that appeals to me even a little. My current project seems like it will take a few years to complete and it will in all probability never see the light of day since I have never actually completed a game before. This is the most irrational habit I have and I hate it but I don't know how to stop. EDIT: I typed this out in the hopes that somehow the act of writing it down and LW users commenting on it would kick my brain into realizing how irrational it was being, and it worked exactly as planned. I will start working on a small project starting tomorrow. Thanks guys.

there have also been a few huge disaster-threads recently that really damaged my personal affect regarding this community. When everybody in The Rationality Club (tm) starts acting like children, defect-defecting on each other and statusmongering and basically looking indistinguishable from my Facebook feed

I'm curious, which threads are you referring to?

3moridinamael
I found a lot of behavior in the White Lies thread to be disappointing, not in content but in tone and how people were treating each other. I think it affected me so much that I've been reading other threads recently with a bad taste in my mouth, because I frankly can't point to any other threads and say "this one was also a nightmare" but it just feels like the level of civility across the community took a big hit, or maybe my faith took the hit and it's coloring my reading.

I think complement can mean both too. E.g. red and green are complementary colors, whereas the sets "red" and "not-red" are complements).

1Tedav
My sense of the word complement is that if two things are complements, they sum to 1, or some equivalent. A is the complement of ~A because P(A or ~A) = 1 Red and green are considered to be complementary colors because together they contain all primary colors of pigments. [although, that is based on the societal understanding that the primary colors are Red, Yellow and Blue. This is actually incorrect. For pigments, the primary colors are really Magenta, Yellow, and Cyan. For light, they are Red, Green, and Blue.]

Improve the ergonomics of your computer situation:

  • Better chair
  • Better desk
  • Keyboard without a numpad so that the mouse doesn't need to be so far out
  • Bigger monitors/multiple monitors
  • If your computer is at all slow or annoying-to-use, consider whether better hardware could help that (and thus reduce the stress of using it). E.g. getting an SSD could decrease load times if you find those problematic

Buy nice clothes

4hodmt160

Strongly seconding the SSD recomendation. I can't think of anything else that's given so much enjoyment for the money. A SSD dramatically increases perceived performance of a computer beyond what you'd expect from benchmarks. Adding extra ram can hide the latency of a mechanical HD by caching, but it does nothing for worst case performance, and worst case performance is highly salient. I'd much rather use a low spec PC with a SSD than a high spec PC with a mechanical HD. Predictably mediocre performance feels faster than high average performance with high variance.

I'm still really happy with buying a massage cushion (not this one but about this type and price). I bought it shortly after I got my first job, and wanted one, noticed it wasn't too expensive (per massage), and went for it. It's a nice treat that still feels luxurious and indulgent, so I also desire other indulgent things less. Plus, I named mine "Adulthood" since I could buy it because I was an adult and my money was mine to do with as I wished. Thus my roommates and I were prone to say things like:

Lukeprog's How to Beat Procrastination is a good instructional for building any kind of habit. Personally none of it really stuck for me until I read Nick Winter's The Motivation Hacker though (it has basically the same information as Luke's post, it just stuck with me more).

Beeminder is also a good way to pre-commit (mentioned in both Luke's post and The Motivation Hacker) to things in order to combat impulsiveness. I recommend this approach to using beeminder in order to also increase expectancy. Impulsiveness and expectancy are two of the components in ... (read more)

It looks like my initial post was mainly about the 'meaning' part of Lukeprog's suggestions for 'Increasing Value' - so, at the least, it seems like I'm at least partly on the right track.
PECOS-970

Precommitment is an interesting aspect of game theory that ties in well with lukeprog's how to beat procrastination.

0findis
Yep. The most common model that yields a rational agent who will choose to restrict zir own future actions is beta-delta discounting, or time inconsistent preferences. I've had problem sets with such questions, usually involving a student procrastinating on an assignment; I don't think I can copy them, but let me know if you want me to sketch out how such a problem might look. Actually, maybe the most instrumental-rationality-enhancing topics to cover that have legitimate game theoretic aspects are in behavioral economics. Perhaps you could construct examples where you contrast the behavior of an agent who interprets probabilities in a funny way, as in Prospect Theory, with an agent who obeys the vNM axioms.
somervta120

please cover the difference between precommitment and saying out loud (Or even believing) "I precommit not to succumb to blackmail/let the AI out of the box". This is one of the most common mistakes I've seen, even on LW

PECOS-910

Second, you make the things you want to do aversive by telling yourself to do them and then not doing them.

I think this is really important. It also fits into the procrastination equation by decreasing expectancy.

PECOS-990

Since you said in another comment your area of interest is medicine, you could study statistics (and work on statistics problem sets during boring lectures -- problem sets are just a type of puzzle that also build more useful skills besides keeping your brain busy).

That's an excellent suggestion! My statistics skills definitely need some polishing.

Can you explain this? I always thought of game theory as being like calculus, and not about human values (like this comment says).

0James_Miller
You solve games by having solution criteria . Unfortunately, for any reasonable list of solution criteria you will always be able to find games where the result doesn't seem to make sense. Also, there is no set of obviously correct and complete solution concepts. Consider the following game: Two rational people simultaneously and secretly write down a real number [0,100]. The person who writes down the highest number gets a payoff of zero, and the person who writes down the lowest number gets that as his payoff. If there is a tie they each get zero. What happens? The only "Nash equilibrium" (the most important solution concept in all of game theory) is for both players to write down 0, but this is a crazy result because picking 0 is weakly dominated by picking any other number (expect 100). Game theory also has trouble solving many games where (a) Player Two only gets to move if Player One does a certain thing, (b) Player One's strategy is determined by what he expects Player Two would do if Player Two gets to move, and (c) in equilibrium Player Two never moves.

It sounds like some of these emotional issues could be helped by working through the exercises in a book like The Feeling Good Handbook, which has been shown to be about as effective as therapy for treating depression. Make sure you actually write out the exercises, don't just read them or think about them, you have to actually write for them to be effective.

PECOS-920

The Feeling Good Handbook has good evidence as a treatment for depression and could help you to identify and address your automatic thoughts caused by negative feedback.

The purpose of that suggestion is to protect against dictionary attacks. Agreed that the advice "should not contain any word in any language" is overly strict (better advice would be "should not simply be one or two words in some language").

Regardless, password recipes are a solution for the problem of coming up with a different password for different services. Even using the technique in the comic to remember phrases like "correct horse battery staple", it would be difficult to remember a different password for dozens of services compared to just remembering a single password recipe.

PECOS-9-10

I like the approach of password recipes to have a unique password for each service without needing to memorize very much.

"memory wiping" might not be the best term for it, since the memory is still in there, just really hard to access, but it's definitely a real effect.

I've also personally used hypnosis to achieve the effects on friends of mine (who I'm certain weren't just pretending), as well as to many strangers on omegle (who could have been pretending, but based on what I know about hypnosis I doubt they were).

PECOS-9-10

I think that a lot of Derren Brown's stuff, while not exactly fake, is done by hypnotizing them off-camera.

So he either hypnotizes them and finds out some information then wipes the memory of them telling him the information, or he hypnotizes them and gives a post-hypnotic suggestion that they will make a specific choice (but not remember being hypnotized to make the choice).

6Protagoras
Can you cite any evidence that hypnotism can have such effects on memory? As I understand it, the research on hypnotism largely indicates that such effect as it has is no more than you would expect from the fact that people are far more deferential to authority and inclined to do what they're told to do than they realize. Wiping memories and post-hypnotic suggestion were, I though, confined to fictional hypnotism.

Unless peirce is interested in going back to the clubs, that sounds like it could make the activity even better (from a getting-over-social-anxiety perspective).

Part of what such exercises are about is demostrating yourself that you have agency. If you lose control over the situation in a way that you didn't expect beforehand and people disapprove of you in that way it doesn't encourage yourself to see your own agency.

Depending on peirce's psychology, doing something in a club and being thrown out might be analogue to cautiously stepping out of your house after staying there for months for fear of spiders and ending up covered in tarantulas.

So I could set up a commitment contract stating I must do each of these activities until my anxiety has decreased to half of its initial level by the end of a certain date.
