Among my friends interested in rationality, effective altruism, and existential risk reduction, I often hear: "If you want to have a real positive impact on the world, grad school is a waste of time. It's better to use deliberate practice to learn whatever you need instead of working within the confines of an institution."
While I'd agree that grad school will not make you do good for the world, if you're a self-driven person who can spend time in a PhD program deliberately acquiring skills and connections for making a positive difference, I think you can make grad school a highly productive path, perhaps more so than many alternatives. In this post, I want to share some advice that I've been repeating a lot lately for how to do this:
- Find a flexible program. PhD programs in mathematics, statistics, philosophy, and theoretical computer science tend to give you a great deal of free time and flexibility, provided you can pass the various qualifying exams without too much studying. By contrast, sciences like biology and chemistry can require time-consuming laboratory work that you can't always speed through by being clever.
- Choose high-impact topics to learn about. AI safety and existential risk reduction are my favorite examples, but there are others, and I won't spend more time here arguing their case. If you can't make your thesis directly about such a topic, choosing a related more popular topic can give you valuable personal connections, and you can still learn whatever you want during the spare time a flexible program will afford you.
- Teach classes. Grad programs that let you teach undergraduate tutorial classes provide a rare opportunity to practice engaging a non-captive audience. If you just want to work on general presentation skills, maybe you practice on your friends... but your friends already like you. If you want to learn to win over a crowd that isn't particularly interested in you, try teaching calculus! I've found this skill particularly useful when presenting AI safety research that isn't yet mainstream, which requires carefully stepping through arguments that are unfamiliar to the audience.
- Use your freedom to accomplish things. I used my spare time during my PhD program to cofound CFAR, the Center for Applied Rationality. Alumni of our workshops have gone on to do such awesome things as creating the Future of Life Institute and sourcing a $10MM donation from Elon Musk to fund AI safety research. I never would have had the flexibility to volunteer for weeks at a time if I'd been working at a typical 9-to-5 or a startup.
- Organize a graduate seminar. Organizing conferences is critical to getting the word out on important new research, and in fact, running a conference on AI safety in Puerto Rico is how FLI was able to bring so many researchers together on its Open Letter on AI Safety. It's also where Elon Musk made his donation. During grad school, you can get lots of practice organizing research events by running seminars for your fellow grad students. In fact, several of the organizers of the FLI conference were grad students.
- Get exposure to experts. A top 10 US school will have professors around that are world-experts on myriad topics, and you can attend departmental colloquia to expose yourself to the cutting edge of research in fields you're curious about. I regularly attended cognitive science and neuroscience colloquia during my PhD in mathematics, which gave me many perspectives that I found useful working at CFAR.
- Learn how productive researchers get their work done. Grad school surrounds you with researchers, and by getting exposed to how a variety of researchers do their thing, you can pick and choose from their methods and find what works best for you. For example, I learned from my advisor Bernd Sturmfels that, for me, quickly passing a draft back and forth with a coauthor can get a paper written much more quickly than agonizing about each revision before I share it.
- Remember you don't have to stay in academia. If you limit yourself to only doing research that will get you good post-doc offers, you might find you aren't able to focus on what seems highest impact (because often what makes a topic high impact is that it's important and neglected, and if a topic is neglected, it might not be trendy enough land you good post-doc). But since grad school is run by professors, becoming a professor is usually the most salient path forward for most grad students, and you might end up pressuring yourself to follow that standards of that path. When I graduated, I got my top choice of post-doc, but then I decided not to take it and to instead try earning to give as an algorithmic stock trader, and now I'm a research fellow at MIRI. In retrospect, I might have done more valuable work during my PhD itself if I'd decided in advance not to do a typical post-doc.
That's all I have for now. The main sentiment behind most of this, I think, is that you have to be deliberate to get the most out of a PhD program, rather than passively expecting it to make you into anything in particular. Grad school still isn't for everyone, and far from it. But if you were seriously considering it at some point, and "do something more useful" felt like a compelling reason not to go, be sure to first consider the most useful version of grad that you could reliably make for yourself... and then decide whether or not to do it.
Please email me (email@example.com) if you have more ideas for getting the most out of grad school!
When you think of "ultimatums", what comes to mind?
Manipulativeness, maybe? Ultimatums are typically considered a negotiation tactic, and not a very pleasant one.
But there's a different thing that can happen, where an ultimatum is made, but where articulating it isn't a speech act but rather an observation. As in, the ultimatum wasn't created by the act of stating it, but rather, it already existed in some sense.
Some concrete examples: negotiating relationships
I had a tense relationship conversation a few years ago. We'd planned to spend the day together in the park, and I was clearly angsty, so my partner asked me what was going on. I didn't have a good handle on it, but I tried to explain what was uncomfortable for me about the relationship, and how I was confused about what I wanted. After maybe 10 minutes of this, she said, "Look, we've had this conversation before. I don't want to have it again. If we're going to do this relationship, I need you to promise we won't have this conversation again."
I thought about it. I spent a few moments simulating the next months of our relationship. I realized that I totally expected this to come up again, and again. Earlier on, when we'd had the conversation the first time, I hadn't been sure. But it was now pretty clear that I'd have to suppress important parts of myself if I was to keep from having this conversation.
"...yeah, I can't promise that," I said.
"I guess that's it then."
"I guess so."
I think a more self-aware version of me could have recognized, without her prompting, that my discomfort represented an unreconcilable part of the relationship, and that I basically already wanted to break up.
The rest of the day was a bit weird, but it was at least nice that we had resolved this. We'd realized that it was a fact about the world that there wasn't a serious relationship that we could have that we both wanted.
I sensed that when she posed the ultimatum, she wasn't doing it to manipulate me. She was just stating what kind of relationship she was interested in. It's like if you go to a restaurant and try to order a pad thai, and the waiter responds, "We don't have rice noodles or peanut sauce. You either eat somewhere else, or you eat something other than a pad thai."
An even simpler example would be that at the start of one of my relationships, my partner wanted to be monogamous and I wanted to be polyamorous (i.e. I wanted us both to be able to see other people and have other partners). This felt a bit tug-of-war-like, but eventually I realized that actually I would prefer to be single than be in a monogamous relationship.
I expressed this.
It was an ultimatum! "Either you date me polyamorously or not at all." But it wasn't me "just trying to get my way".
I guess the thing about ultimatums in the territory is that there's no bluff to call.
It happened in this case that my partner turned out to be really well-suited for polyamory, and so this worked out really well. We'd decided that if she got uncomfortable with anything, we'd talk about it, and see what made sense. For the most part, there weren't issues, and when there were, the openness of our relationship ended up just being a place where other discomforts were felt, not a generator of disconnection.
Normal ultimatums vs ultimatums in the territory
I use "in the territory" to indicate that this ultimatum isn't just a thing that's said but a thing that is true independently of anything being said. It's a bit of a poetic reference to the map-territory distinction.
No bluffing: preferences are clear
The key distinguishing piece with UITTs is, as I mentioned above, that there's no bluff to call: the ultimatum-maker isn't secretly really really hoping that the other person will choose one option or the other. These are the two best options as far as they can tell. They might have a preference: in the second story above, I preferred a polyamorous relationship to no relationship. But I preferred both of those to a monogamous relationship, and the ultimatum in the territory was me realizing and stating that.
This can actually be expressed formally, using what's called a preference vector. This comes from Keith Hipel at University of Waterloo. If the tables in this next bit doesn't make sense, don't worry about it: all important conclusions are expressed in the text.
First, we'll note that since each of us have two options, a table can be constructed which shows four possible states (numbered 0-3 in the boxes).
This representation is sometimes referred to as matrix form or normal form, and has the advantage of making it really clear who controls which state transitions (movements between boxes). Here, my decision controls which column we're in, and my partner's decision controls which row we're in.
Next, we can consider: of these four possible states, which are most and least preferred, by each person? Here's my preferences, ordered from most to least preferred, left to right. The 1s in the boxes mean that the statement on the left is true.
The order of the states represents my preferences (as I understand them) regardless of what my potential partner's preferences are. I only control movement in the top row (do I insist on polyamory or not). It's possible that they prefer no relationship to a poly relationship, in which case we'll end up in state 2. But I still prefer this state over state 1 (mono relationship) and state 0 (in which I don't ask for polyamory and my partner decides not to date me anyway). So whatever my partners preferences are, I've definitely made a good choice for me, by insisting on polyamory.
This wouldn't be true if I were bluffing (if I preferred state 1 to state 2 but insisted on polyamory anyway). If I preferred 1 to 2, but I bluffed by insisting on polyamory, I would basically be betting on my partner preferring polyamory to no relationship, but this might backfire and get me a no relationship, when both of us (in this hypothetical) would have preferred a monogamous relationship to that. I think this phenomenon is one reason people dislike bluffy ultimatums.
My partner's preferences turned out to be...
You'll note that they preferred a poly relationship to no relationship, so that's what we got! Although as I said, we didn't assume that everything would go smoothly. We agreed that if this became uncomfortable for my partner, then they would tell me and we'd figure out what to do. Another way to think about this is that after some amount of relating, my partner's preference vector might actually shift such that they preferred no relationship to our polyamorous one. In which case it would no longer make sense for us to be together.
UITTs release tension, rather than creating it
In writing this post, I skimmed a wikihow article about how to give an ultimatum, in which they say:
"Expect a negative reaction. Hardly anyone likes being given an ultimatum. Sometimes it may be just what the listener needs but that doesn't make it any easier to hear."
I don't know how accurate the above is in general. I think they're talking about ultimatums like "either you quit smoking or we break up". I can say that expect that these properties of an ultimatum contribute to the negative reaction:
- stated angrily or otherwise demandingly
- more extreme than your actual preferences, because you're bluffing
- refers to what they need to do, versus your own preferences
So this already sounds like UITTs would have less of a negative reaction.
But I think the biggest reason is that they represent a really clear articulation of what one party wants, which makes it much simpler for the other party to decide what they want to do. Ultimatums in the territory tend to also be more of a realization that you then share, versus a deliberate strategy. And this realization causes a noticeable release of tension in the realizer too.
"Either you quit smoking or we break up!"
"I'm realizing that as much as I like our relationship, it's really not working for me to be dating a smoker, so I've decided I'm not going to. Of course, my preferred outcome is that you stop smoking, not that we break up, but I realize that might not make sense for you at this point."
Of course, what's said here doesn't necessarily correspond to the preference vectors shown above. Someone could say the demanding first thing when they actually do have a UITT preference-wise, and someone who's trying to be really NVCy or something might say the sceond thing even though they're actually bluffing and would prefer to . But I think that in general they'll correlate pretty well.
The "realizing" seems similar to what happened to me 2 years ago on my own, when I realized that the territory was issuing me an ultimatum: either you change your habits or you fail at your goals. This is how the world works: your current habits will get you X, and you're declaring you want Y. On one level, it was sad to realize this, because I wanted to both eat lots of chocolate and to have a sixpack. Now this ultimatum is really in the territory.
Another example could be realizing that not only is your job not really working for you, but that it's already not-working to the extent that you aren't even really able to be fully productive. So you don't even have the option of just working a bit longer, because things are only going to get worse at this point. Once you realize that, it can be something of a relief, because you know that even if it's hard, you're going to find something better than your current situation.
More thoughts on the break-up story
One exercise I have left to the reader is creating the preference vectors for the break-up in the first story. HINT: (rot13'd) Vg'f fvzvyne gb gur cersrerapr irpgbef V qvq fubj, jvgu gjb qrpvfvbaf: fur pbhyq vafvfg ba ab shgher fhpu natfgl pbairefngvbaf be abg, naq V pbhyq pbagvahr gur eryngvbafuvc be abg.
An interesting note is that to some extent in that case I wasn't even expressing a preference but merely a prediction that my future self would continue to have this angst if it showed up in the relationship. So this is even more in the territory, in some senses. In my model of the territory, of course, but yeah. You can also think of this sort of as an unconscious ultimatum issued by the part of me that already knew I wanted to break up. It said "it's preferable for me to express angst in this relationship than to have it be angst free. I'd rather have that angst and have it cause a breakup than not have the angst."
I think that ultimatums in the territory are also connected to what I've called Reveal Culture (closely related to Tell Culture, but framed differently). Reveal cultures have the assumption that in some fundamental sense we're on the same side, which makes negotiations a very different thing... more of a collaborative design process. So it's very compatible with the idea that you might just clearly articulate your preferences.
Note that there doesn't always exist a UITT to express. In the polyamory example above, if I'd preferred a mono relationship to no relationship, then I would have had no UITT (though I could have bluffed). In this case, it would be much harder for me to express my preferences, because if I leave them unclear then there can be kind of implicit bluffing. And even once articulated, there's still no obvious choice. I prefer this, you prefer that. We need to compromise or something. It does seem clear that, with these preferences, if we don't end up with some relationship at the end, we messed up... but deciding how to resolve it is outside the scope of this post.
Knowing your own preferences is hard
Another topic this post will point at but not explore is: how do you actually figure out what you want? I think this is a mix of skill and process. You can get better at the general skill by practising trying to figure it out (and expressing it / acting on it when you do, and seeing if that works out well). One process I can think of that would be helpful is Gendlin's Focusing. Nate Soares has written about how introspection is hard and to some extent you don't ever actually know what you want: You don't get to know what you're fighting for. But, he notes,
"There are facts about what we care about, but they aren't facts about the stars. They are facts about us."
And they're hard to figure out. But to the extent that we can do so and then act on what we learn, we can get more of what we want, in relationships, in our personal lives, in our careers, and in the world.
(This article crossposted from my personal blog.)
Previously, I talked about the mystery of pain and pleasure, and how little we know about what sorts of arrangements of particles intrinsically produce them.
Up now: should FAI researchers care about this topic? Is research into the information theory of pain and pleasure relevant for FAI? I believe so! Here are the top reasons I came up with while thinking about this topic.
An important caveat: much depends on whether pain and pleasure (collectively, 'valence') are simple or complex properties of conscious systems. If they’re on the complex end of the spectrum, many points on this list may not be terribly relevant for the foreseeable future. On the other hand, if they have a relatively small “kolmogorov complexity” (e.g., if a ‘hashing function’ to derive valence could fit on a t-shirt), crisp knowledge of valence may be possible sooner rather than later, and could have some immediate relevance to current FAI research directions.
Additional caveats: it’s important to note that none of these ideas are grand, sweeping panaceas, or are intended to address deep metaphysical questions, or aim to reinvent the wheel- instead, they’re intended to help resolve empirical ambiguities and modestly enlarge the current FAI toolbox.
1. Valence research could simplify the Value Problem and the Value Loading Problem. If pleasure/happiness is an important core part of what humanity values, or should value, having the exact information-theoretic definition of it on-hand could directly and drastically simplify the problems of what to maximize, and how to load this value into an AGI.
2. Valence research could form the basis for a well-defined ‘sanity check’ on AGI behavior. Even if pleasure isn’t a core terminal value for humans, it could still be used as a useful indirect heuristic for detecting value destruction. I.e., if we’re considering having an AGI carry out some intervention, we could ask it what the expected effect is on whatever pattern precisely corresponds to pleasure/happiness. If there’s be a lot less of that pattern, the intervention is probably a bad idea.
3. Valence research could help us be humane to AGIs and WBEs. There’s going to be a lot of experimentation involving intelligent systems, and although many of these systems won’t be “sentient” in the way humans are, some system types will approach or even surpass human capacity for suffering. Unfortunately, many of these early systems won’t work well— i.e., they’ll be insane. It would be great if we had a good way to detect profound suffering in such cases and halt the system.
4. Valence research could help us prevent Mind Crimes. Nick Bostrom suggests in Superintelligence that AGIs might simulate virtual humans to reverse-engineer human preferences, but that these virtual humans might be sufficiently high-fidelity that they themselves could meaningfully suffer. We can tell AGIs not to do this- but knowing the exact information-theoretic pattern of suffering would make it easier to specify what not to do.
5. Valence research could enable radical forms of cognitive enhancement. Nick Bostrom has argued that there are hard limits on traditional pharmaceutical cognitive enhancement, since if the presence of some simple chemical would help us think better, our brains would probably already be producing it. On the other hand, there seem to be fewer a priori limits on motivational or emotional enhancement. And sure enough, the most effective “cognitive enhancers” such as adderall, modafinil, and so on seem to work by making cognitive tasks seem less unpleasant or more interesting. If we had a crisp theory of valence, this might enable particularly powerful versions of these sorts of drugs.
6. Valence research could help align an AGI’s nominal utility function with visceral happiness. There seems to be a lot of confusion with regard to happiness and utility functions. In short: they are different things! Utility functions are goal abstractions, generally realized either explicitly through high-level state variables or implicitly through dynamic principles. Happiness, on the other hand, seems like an emergent, systemic property of conscious states, and like other qualia but unlike utility functions, it’s probably highly dependent upon low-level architectural and implementational details and dynamics. In practice, most people most of the time can be said to have rough utility functions which are often consistent with increasing happiness, but this is an awfully leaky abstraction.
My point is that constructing an AGI whose utility function is to make paperclips, and constructing a sentient AGI who is viscerally happy when it makes paperclips, are very different tasks. Moreover, I think there could be value in being able to align these two factors— to make an AGI which is viscerally happy to the exact extent it’s maximizing its nominal utility function.
(Why would we want to do this in the first place? There is the obvious semi-facetious-but-not-completely-trivial answer— that if an AGI turns me into paperclips, I at least want it to be happy while doing so—but I think there’s real potential for safety research here also.)
7. Valence research could help us construct makeshift utility functions for WBEs and Neuromorphic AGIs. How do we make WBEs or Neuromorphic AGIs do what we want? One approach would be to piggyback off of what they already partially and imperfectly optimize for already, and build a makeshift utility function out of pleasure. Trying to shoehorn a utility function onto any evolved, emergent system is going to involve terrible imperfections, uncertainties, and dangers, but if research trends make neuromorphic AGI likely to occur before other options, it may be a case of “something is probably better than nothing.”
One particular application: constructing a “cryptographic reward token” control scheme for WBEs/neuromorphic AGIs. Carl Shulman has suggested we could incentivize an AGI to do what we want by giving it a steady trickle of cryptographic reward tokens that fulfill its utility function- it knows if it misbehaves (e.g., if it kills all humans), it’ll stop getting these tokens. But if we want to construct reward tokens for types of AGIs that don’t intrinsically have crisp utility functions (such as WBEs or neuromorphic AGIs), we’ll have to understand, on a deep mathematical level, what they do optimize for, which will at least partially involve pleasure.
8. Valence research could help us better understand, and perhaps prevent, AGI wireheading. How can AGI researchers prevent their AGIs from wireheading (direct manipulation of their utility functions)? I don’t have a clear answer, and it seems like a complex problem which will require complex, architecture-dependent solutions, but understanding the universe’s algorithm for pleasure might help clarify what kind of problem it is, and how evolution has addressed it in humans.
9. Valence research could help reduce general metaphysical confusion. We’re going to be facing some very weird questions about philosophy of mind and metaphysics when building AGIs, and everybody seems to have their own pet assumptions on how things work. The better we can clear up the fog which surrounds some of these topics, the lower our coordinational friction will be when we have to directly address them.
Successfully reverse-engineering a subset of qualia (valence- perhaps the easiest type to reverse-engineer?) would be a great step in this direction.
10. Valence research could change the social and political landscape AGI research occurs in. This could take many forms: at best, a breakthrough could lead to a happier society where many previously nihilistic individuals suddenly have “skin in the game” with respect to existential risk. At worst, it could be a profound information hazard, and irresponsible disclosure or misuse of such research could lead to mass wireheading, mass emotional manipulation, and totalitarianism. Either way, it would be an important topic to keep abreast of.
These are not all independent issues, and not all are of equal importance. But, taken together, they do seem to imply that reverse-engineering valence will be decently relevant to FAI research, particularly with regard to the Value Problem, reducing metaphysical confusion, and perhaps making the hardest safety cases (e.g., neuromorphic AGIs) a little bit more tractable.
As part of a broader project of promoting rationality, Raelifin and I had some luck in getting media coverage of rationality-informed approaches to probabilistic thinking (1, 2), mental health (1, 2), and reaching life goals through finding purpose and meaning (1, 2). The media includes mainstream media such as the main newspaper in Cleveland, OH; reason-oriented media such as Unbelievers Radio; student-oriented media such as the main newspaper for Ohio State University; and self improvement-oriented media such as the Purpose Revolution.
This is part of our strategy to reach out both to mainstream and to niche groups interested in a specific spin on rationality-informed approaches to winning at life. I wanted to share these here, and see if any of you had suggestions for optimizations of our performance, connections with other media channels both mainstream and nice, and any other thoughts on improving outreach. Thanks!
Irrationality is ingrained in our humanity. It is fundamental to who we are. This is because being human means that you are implemented on kludgy and limited wetware (a human brain). A consequence of this is that biases ↓ and irrational thinking are not mistakes, persay, they are not misfirings or accidental activations of neurons. They are the default mode of operation for wetware that has been optimized for purposes other than truth maximization.
If you want something to blame for the fact that you are innately irrational, then you can blame evolution ↓. Evolution tends to not to produce optimal organisms, but instead produces ones that are kludgy ↓, limited and optimized for criteria relating to ancestral environments rather than for criteria relating to optimal thought.
A kludge is a clumsy or inelegant, yet surprisingly effective, solution to a problem. The human brain is an example of a kludge. It contains many distinct substructures dating from widely separated periods of evolutionary development ↓. An example of this is the two kinds of processes in human cognition where one is fast (type 1) and the other is slow (type2) ↓.
There are many other characteristics of the brain that induce irrationality. The main ones are that:
- The brain is innately limited in its computational abilities and so it must use heuristics ↓, which are mental shortcuts that ease the cognitive load of making a decision.
- The brain has a tendency to blindly use salient or pre-existing responses to answers rather than developing new answers or thoroughly checking pre-existing solutions ↓.
- The brain does not inherently value truth. One of the main reasons for this is that many of the biases can actually be adaptive. An example of an adaptive bias is the sexual over perception bias ↓ in men. From a truth-maximization perspective young men who assume that all women want them are showing severe social-cognitive inaccuracies, judgment biases, and probably narcissistic personality disorder. However, from an evolutionary perspective, the same young men are behaving in a more optimal manner. One which has consistently maximized the reproductive success of their male ancestors. Another similar example is the bias for positive perception of partners ↓.
- The brain acts more like a coherence maximiser than a truth maximiser, which makes people liable to believing falsehoods ↓. If you want to believe something or you are often in situations in which two things just happen to be related then your brain is often by default going to treat them as if they were right ↓.
- The brain trusts its own version of reality much more than other peoples. This makes people defend their beliefs even when doing so is extremely irrational ↓. It is also makes it hard for people to change their minds ↓ and to accept when they are wrong ↓
- Disbelief requires System 2 thought ↓. This means that if system 2 is engaged then we are liable to believe pretty much anything. System 1 is gullible and biased to believe. It is system 2 that is in charge of doubting and disbelieving.
One important non-brain related factor is that we must make use of and live with our current adaptations ↓. People cannot reconform themselves to fulfill purposes suitable to their current environment, but must instead make use of pre-existing machinery that has been optimised for other environments. This means that there is probably never going to be any miracle cures to irrationality because eradicating it would require that you were so fundamentally altered that you were no longer human.
One of the first major steps on the path to becoming more rational, is the realisation that you are not only by default irrational, but that you are always fundamentally comprimised. This doesn't mean that improving your rationality is impossible. It just means that if you stop applying your knowledge of what improves rationality then you will slip back into irrationality. This is because the brain is a kludge. It works most of the time, but in some cases its innate and natural course of action must be diverted if we are to be rational. The good news is that this kind of diversion is possible. This is because humans possess second order thinking ↓. This means that they can observe their inherent flaws and systematic errors. They can then through studying the laws of thought and action apply second order corrections and from doing so become more rational.
The process of applying these second order corrections or training yourself to mitigate the effects of your propensities is called debiasing ↓. Debiasing is not a thing that you can do once and then forget about. It is something that you must either be doing constantly or that you must instill into habits so that it occurs without volitional effort. There are generally three main types of debaising and they are described below:
- Counteracting the effects of bias - this can be done by adjusting your estimates or opinions in order to avoid errors due to biases. This is probably the hardest of the three types of debiasing because to do it correctly you need to know exactly how much you are already biased. This is something that people are rarely aware of.
- Catching yourself when you are being or could be biased and applying a cogntive override. The basic idea behind this is that you observe and track your own thoughts and emotions so that you can catch yourself before you move to deeply into irrational modes of thinking. This is hard because it requires that you have superb self-awareness skills and these often take a long time to develop and train. Once you have caught yourself it is often best to resort to using formal thought in algebra, logic, probability theory or decision theory etc. It is also useful to instill habits in yourself that would allow this observation to occur without conscious and volitional effort. It should be noted that incorrectly applying the first two methods of debiasing can actually make you more biased and that this is a common conundrum and problem faced by beginners to rationality training ↓.
- Understanding the situations which make you biased so that you can avoid them ↓ - the best way to achieve this is simply to ask yourself: how can I become more objective? You do this by taking your biased and faulty perspective as much as possible out of the equation. For example, instead of taking measurements yourself you could get them taken automatically by some scientific instrument.
- Bias - refers to the obstacles to truth which are produced by our kludgy and limited wetware (brains) working exactly the way that they should. ↩
- Evolutionary psychology - the idea of evolution as the idiot designer of humans - that our brains are not consistently well-designed - is a key element of many of the explanations of human errors that appear on this website.
- Slowness of evolution- The tremendously slow timescale of evolution, especially for creating new complex machinery (as opposed to selecting on existing variance), is why the behavior of evolved organisms is often better interpreted in terms of what did in fact work ↩
- Alief - an independent source of emotional reaction which can coexist with a contradictory belief. For example, the fear felt when a monster jumps out of the darkness in a scary movie is based on the alief that the monster is about to attack you, even though you believe that it cannot.
- Wanting and liking - The reward system consists of three major components:
- Liking: The 'hedonic impact' of reward, comprised of (1) neural processes that may or may not be conscious and (2) the conscious experience of pleasure.
- Wanting: Motivation for reward, comprised of (1) processes of 'incentive salience' that may or may not be conscious and (2) conscious desires.
- Learning: Associations, representations, and predictions about future rewards, comprised of (1) explicitpredictions and (2) implicit knowledge and associative conditioning (e.g. Pavlovian associations). ↩
- Heuristics and biases - program in cognitive psychology tries to work backward from biases (experimentally reproducible human errors) to heuristics (the underlying mechanisms at work in the brain). ↩
- Cached thought – is an answer that was arrived at by recalling a previously-computed conclusion, rather than performing the reasoning from scratch. ↩
- Sympathetic Magic - humans seem to naturally generate a series of concepts known as sympathetic magic, a host of theories and practices which have certain principles in common, two of which are of overriding importance: the Law of Contagion holds that two things which have interacted, or were once part of a single entity, retain their connection and can exert influence over each other; the Law of Similarity holds that things which are similar or treated the same establish a connection and can affect each other. ↩

Notes on decisions I have made while creating this post
(these notes will not be in the final draft):
- This post doesn't have any specific details on debiasing or the biases. I plan to provide these details in later posts. The main point of this post is convey the idea in the title.
I recently encountered something that is, in my opinion, one of the most absurd failure modes of the human brain. I first encountered this after introspection on useful things that I enjoy doing, such as programming and writing. I noticed that my enjoyment of the activity doesn't seem to help much when it comes to motivation for earning income. This was not boredom from too much programming, as it did not affect my interest in personal projects. What it seemed to be, was the brain categorizing activities into "work" and "fun" boxes. On one memorable occasion, after taking a break due to being exhausted with work, I entertained myself, by programming some more, this time on a hobby personal project (as a freelancer, I pick the projects I work on so this is not from being told what to do). Relaxing by doing the exact same thing that made me exhausted in the first place.
The absurdity of this becomes evident when you think about what distinguishes "work" and "fun" in this case, which is added value. Nothing changes about the activity except the addition of more utility, making a "work" strategy always dominate a "fun" strategy, assuming the activity is the same. If you are having fun doing something, handing you some money can't make you worse off. Making an outcome better makes you avoid it. Meaning that the brain is adopting a strategy that has a (side?) effect of minimizing future utility, and it seems like it is utility and not just money here - as anyone who took a class in an area that personally interested them knows, other benefits like grades recreate this effect just as well. This is the reason I think this is among the most absurd biases - I can understand akrasia, wanting the happiness now and hyperbolically discounting what happens later, or biases that make something seem like the best option when it really isn't. But knowingly punishing what brings happiness just because it also benefits you in the future? It's like the discounting curve dips into the negative region. I would really like to learn where is the dividing line between which kinds of added value create this effect and which ones don't (like money obviously does, and immediate enjoyment obviously doesn't). Currently I'm led to believe that the difference is present utility vs. future utility, (as I mentioned above) or final vs. instrumental goals, and please correct me if I'm wrong here.
This is an effect that has been studied in psychology and called the overjustification effect, called that because the leading theory explains it in terms of the brain assuming the motivation comes from the instrumental gain instead of the direct enjoyment, and then reducing the motivation accordingly. This would suggest that the brain has trouble seeing a goal as being both instrumental and final, and for some reason the instrumental side always wins in a conflict. However, its explanation in terms of self-perception bothers me a little, since I find it hard to believe that a recent creation like self-perception can override something as ancient and low-level as enjoyment of final goals. I searched LessWrong for discussions of the overjustification effect, and the ones I found discussed it in the context of self-perception, not decision-making and motivation. It is the latter that I wanted to ask for your thoughts on.
I have noticed I often wish "Damn I wish someone had made an app for that" and when I search for it I can't find it. Then I outsource the search to facebook or other people; and they can usually say - yes, its called X. Which I can put down to an inability to know how to search for an app on my part; more than anything else.
With that in mind; I wanted to solve the problem of finding apps for other people.
The following is a list of apps that I find useful (and use often) for productive reasons:
This list is long. The most valuable ones are the top section that I use regularly.
Other things to mention:
Internal storage - I have a large internal memory card because I knew I would need lots of space. So I played the "out of sight out of mind game" and tried to give myself as much space as possible by buying a large internal card.
Battery - I use anker external battery blocks to save myself the trouble of worrying about batteries. If prepared I leave my house with 2 days of phone charge (of 100% use). I used to count "wins" of days I beat my phone battery (stay awake longer than it) but they are few and far between. Also I doubled my external battery power and it sits at two days not one (28000mA + 2*460ma spare phone batteries)
Phone - I have a Samsung S4 (android Running KitKat) because it has a few features I found useful that were not found in many other phones - Cheap, Removable battery, external storage card, replaceable case.
Screen cover - I am using the one that came with the phone still
I carry a spare phone case, in the beginning I used to go through one each month; now I have a harder case than before it hasn't broken.
MicroUSB cables - I went through a lot of effort to sort this out, it's still not sorted, but its "okay for now". The advice I have - buy several good cables (read online reviews about it), test them wherever possible, and realise that they die. Also carry a spare or two.
Restart - I restart my phone probably most days when it gets slow. It's got programming bugs, but this solution works for now.
These sit on my screen all the time.
Data monitor - Gives an overview of bits per second upload or download. updated every second.
CpuTemp - Gives an overlay of the current core temperature. My phone is always hot, I run it hard with bluetooth, GPS and wifi blaring all the time. I also have a lot of active apps.
Mindfulness bell - My phone makes a chime every half hour to remind me to check, "Am I doing something of high-value right now?" it sometimes stops me from doing crap things.
Facebook chat heads - I often have them open, they have memory leaks and start slowing down my phone after a while, I close and reopen them when I care enough.
Facebook - communicate with people. I do this a lot.
Inkpad - its a note-taking app, but not an exceptionally great one; open to a better suggestion.
Ingress - it makes me walk; it gave me friends; it put me in a community. Downside is that it takes up more time than you want to give it. It's a mobile GPS game. Join the Resistance.
Maps (google maps) - I use this most days; mostly for traffic assistance to places that I know how to get to.
Camera - I take about 1000 photos a month. Generic phone-app one.
Assistive light - Generic torch app (widget) I use this daily.
Hello - SMS app. I don't like it but its marginally better than the native one.
Sunrise calendar - I don't like the native calendar; I don't like this or any other calendar. This is the least bad one I have found. I have an app called "facebook sync" which helps with entering in a fraction of the events in my life.
Phone, address book, chrome browser.
GPS logger - I have a log of my current gps location every 5 minutes. If google tracks me I might as well track myself. I don't use this data yet but its free for me to track; so if I can find a use for the historic data that will be a win.
Fit - google fit; here for multiple redundancy
S Health - Samsung health - here for multiple redundancy
Fitbit - I wear a flex step tracker every day, and input my weight daily manually through this app
Basis - I wear a B1 watch, and track my sleep like a hawk.
Rescuetime - I track my hours on technology and wish it would give a better breakdown. (I also paid for their premium service)
Voice recorder - generic phone app; I record around 1-2 hours of things I do per week. Would like to increase that.
Narrative - I recently acquired a life-logging device called a narrative, and don't really know how to best use the data it gives. But its a start.
How are you feeling? - Mood tracking app - this one is broken but the best one I have found, it doesn't seem to open itself after a phone restart; so it won't remind you to enter in a current mood. I use a widget so that I can enter in the mood quickly. The best parts of this app are the way it lets you zoom out, and having a 10 point scale. I used to write a quick sentence about what I was feeling, but that took too much time so I stopped doing it.
Stopwatch - "hybrid stopwatch" - about once a week I time something and my phone didn't have a native one. This app is good at being a stopwatch.
Callinspector - tracks ingoing or outgoing calls and gives summaries of things like, who you most frequently call, how much data you use, etc. can also set data limits.
Powercalc - the best calculator app I could find
Night mode - for saving batter (it dims your screen), I don't use this often but it is good at what it does. I would consider an app that dims the blue light emitted from my screen; however I don't notice any negative sleep effects so I have been putting off getting around to it.
Advanced signal status - about once a month I am in a place with low phone signal - this one makes me feel better about knowing more details of what that means.
Ebay - To be able to buy those $5 solutions to problems on the spot is probably worth more than $5 of "impulse purchases" that they might be classified as.
Cal - another calendar app that sometimes catches events that the first one misses.
ES file explorer - for searching the guts of my phone for files that are annoying to find. Not as used or as useful as I thought it would be but still useful.
Maps.Me - I went on an exploring adventure to places without signal; so I needed an offline mapping system. This map saved my life.
Wikipedia - information lookup
Youtube - don't use it often, but its there.
How are you feeling? (again) - I have this in multiple places to make it as easy as possible for me to enter in this data
Play store - Makes it easy to find.
Gallery - I take a lot of photos, but this is the native gallery and I could use a better app.
In no particular order;
Facebook groups, Yahoo Mail, Skype, Facebook Messenger chat heads, Whatsapp, meetup, google+, Hangouts, Slack, Viber, OKcupid, Gmail, Tinder.
They do social things. Not much to add here.
AnkiDroid - Anki memoriser app for a phone.
MyFitnessPal - looks like a really good app, have not used it
Fitocracy - looked good
I got these apps for a reason; but don't use them.
Not on my front pages:
These I don't use as often; or have not moved to my front pages (skipping the ones I didn't install or don't use)
S memo - samsung note taking thing, I rarely use, but do use once a month or so.
Drive, Docs, Sheets - The google package. Its terrible to interact with documents on your phone, but I still sometimes access things from my phone.
bubble - I don't think I have ever used this
Compass pro - gives extra details about direction. I never use it.
(ingress apps) Glypher, Agentstats, integrated timer, cram, notify
TripView (public transport app for my city)
Convertpad - converts numbers to other numbers. Sometimes quicker than a google search.
ABC Iview - National TV broadcasting channel app. Every program on this channel is uploaded to this app, I have used it once to watch a documentary since I got the app.
AnkiDroid - I don't need to memorise information in the way it is intended to be used; so I don't use it. Cram is also a flashcard app but I don't use it.
First aid - I know my first aid but I have it anyway for the marginal loss of 50mb of space.
Triangle scanner - I can scan details from NFC chips sometimes.
MX player - does videos better than native apps.
Zarchiver - Iunno. Does something.
Pandora - Never used
Soundcloud - used once every two months, some of my friends post music online.
Barcode scanner - never used
Diskusage - Very useful. Visualises where data is being taken up on your phone, helps when trying to free up space.
Swiftkey - Better than native keyboards. Gives more freedom, I wanted a keyboard with black background and pale keys, swiftkey has it.
Google calendar - don't use it, but its there to try to use.
Sleepbot - doesn't seem to work with my phone, also I track with other methods, and I forget to turn it on; so its entirely not useful in my life for sleep tracking.
My service provider's app.
AdobeAcrobat - use often; not via the icon though.
Wheresmydroid? - seems good to have; never used. My phone is attached to me too well for me to lose it often. I have it open most of the waking day maybe.
Uber - I don't use ubers.
Terminal emulator, AIDE, PdDroid party, Processing Android, An editor for processing, processing reference, learn C++ - programming apps for my phone, I don't use them, and I don't program much.
Airbnb - Have not used yet, done a few searches for estimating prices of things.
Heart rate - measures your heart rate using the camera/flash. Neat, not useful other than showing off to people how its possible to do.
Basis - (B1 app), - has less info available than their new app
BPM counter - Neat if you care about what a "BPM" is for music. Don't use often.
Sketch guru - fun to play with, draws things.
DJ studio 5 - I did a dj thing for a friend once, used my phone. was good.
Facebook calendar Sync - as the name says.
Dual N-back - I Don't use it. I don't think it has value giving properties.
Awesome calendar - I don't use but it comes with good reccomendations.
Battery monitor 3 - Makes a graph of temperature and frequency of the cores. Useful to see a few times. Eventually its a bell curve.
urbanspoon - local food places app.
Gumtree - Australian Ebay (also ebay owns it now)
Printer app to go with my printer
Car Roadside assistance app to go with my insurance
Virgin air entertainment app - you can use your phone while on the plane and download entertainment from their in-flight system.
Two things now;
What am I missing? Was this useful? Ask me to elaborate on any app and why I used it. If I get time I will do that anyway.
P.S. this took two hours to write.
P.P.S - I was intending to make, keep and maintain a list of useful apps, that is not what this document is. If there are enough suggestions that it's time to make and keep a list; I will do that.
I don't usually submit articles to Discussion, but this news upset me so much that I think there is a real need to talk about it.
A leading scientific publisher has retracted 64 articles in 10 journals, after an internal investigation discovered fabricated peer-review reports linked to the articles’ publication.
The cull comes after similar discoveries of ‘fake peer review’ by several other major publishers, including London-based BioMed Central, an arm of Springer, which began retracting 43 articles in March citing "reviews from fabricated reviewers". The practice can occur when researchers submitting a paper for publication suggest reviewers, but supply contact details for them that actually route requests for review back to the researchers themselves.
Types of Misconduct
We all know that academia is a tough place to be in. There is constant pressure to 'publish or perish', and people are given promotions and pay raises directly as a result of how many publications and grants they are awarded. I was awarded a PhD recently so the subject of scientific honesty is dear to my heart.
I'm of course aware of misconduct in the field of science. 'Softer' forms of misconduct include things like picking only results that are consistent with your hypothesis or repeating experiments until you get low p-values. This kind of thing sometimes might even happen non-deliberately and subconsciously, which is why it is important to disclose methods and data.
'Harder' forms of misconduct include making up data and fudging numbers in order to get published and cited. This is of course a very deliberate kind of fraud, but it is still easy to see how someone could be led to this kind of behaviour by virtue of the incredible pressures that exist. Here, the goal is not just academic advancement, but also obtaining recognition. The authors in this case are confident that even though their data is falsified, their reasoning (based, of course, on falsified data) is sound and correct and stands up to scrutiny.
What is the problem?
But the kind of misconduct being mentioned in the linked article is extremely upsetting to me, beyond the previous types of misconduct. It is a person or (more likely) a group of people knowing full well that their publication would not stand up to serious scientific scrutiny. Yet they commit the fraud anyway, guessing that no one will actually ever seriously scrutinize their work and it will take it at face value due to being present in a reputable journal. The most upsetting part is that they are probably right in this assessment.
Christie Aschwanden wrote a piece about this recently on FiveThirtyEight. She makes the argument that cases of scientific misconduct are still rare and not important in the grand scheme of things. I only partially agree with this. I agree that science is still mostly trustworthy, but I don't necessarily agree that scientific misconduct is too rare to be worth worrying about. It would be much more honest to say that we simply do not know the extent of scientific misconduct, because there is no comprehensive system in place to detect it. Surveys on this have indicated that as much as 1/3 of scientists admit to some form of questionable practices, with 2% admitting to downright fabrication or falsification of evidence. These figures could be widely off the mark. It is, unfortunately, easy to commit fraud without being detected.
Aschwanden's conclusion is that the problem is that science is difficult. With this I agree wholeheartedly. And to this I'd add that science has probably become too big. A few years ago I did some research in the area of nitric oxide (NO) transmission in the brain. I did a search and found 55,000 scientific articles from reputable publications with "nitric oxide" in the title. Today this number is over 62,000. If you expand this to both the title and abstract, you get about 160,000. Keep in mind that these are only the publications that have actually passed the process of peer review.
I have read only about 1,000 articles total during the entirety of my PhD, and probably <100 in the actual level of depth required to locate flaws in reasoning. The problem with science becoming too big is that it's easy to hide things. There are always going to be fewer fact-checkers than authors, and it is much harder to argue logically about things than it is to simply write things. The more the noise, the harder it becomes to listen.
It was not always this way. The rate of publication is increasing rapidly, outstripping even the rate of growth in number of scientists. Decades ago publications played only a minor role in the scientific process. Publications mostly had the role of disseminating important information to a large audience. Today, the opposite is true - most articles have a small audience (as, in people with the will and ability to read them), consisting of perhaps only a handful of individuals - often only the people in the same research group of institutional department. This leads to the problem where it is often seen that many publications actually receive most of their citations from people who are friends or colleagues of the authors.
Some people have suggested that because of the recent high-level cases of fraud that have been uncovered, there is now increased scrutiny and fraud is going to be uncovered more rapidly. This may be true for the types of fraud that already have been uncovered, but fraudsters are always going to be able to stay ahead of the scrutinizers. Experience with other forms of crime show this quite clearly. Before the article in nature I had never even thought about the possibility of sending reviews back to myself. It simply never occurred to me. All of these considerations lead me to believe that the problem of scientific fraud may actually get worse, not better, over time. Unless the root of the problem is attacked.
How Can it be Solved?
So how to solve the problem of scientific misconduct? I don't have any good answers. I can think of things like "Stop awarding people for mere number of publications" and "Gauge the actual impact of science rather than empty metrics like number of citations or impact factor." But I can't think of any good way to do these things. Some alternatives - like using, for instance, social media to gauge the importance of a scientific discovery - would almost certainly lead to a worse situation than we have now.
A small way to help might be to adopt a payment system for peer-review. That is, to get published, you pay a certain amount of money for researchers to review your work. Currently, most reviewers offer their services for free (however they are sometimes allocated a certain amount of time for peer-review in their academic salary). A pay system would at least give an incentive for people to rigorously review work rather than simply trying to optimize for minimum amount of time invested in review. It would also reduce the practice of parasitic submissions (people submitting to short-turnaround-time, high-profile journals like Nature just to get feedback on their work for free) and decrease the flow volume of papers submitted for review. However, it would also incentivize a higher rate of rejection to maximize profits. And it would disproportionately impact scientists from places with less scientific funding.
What are the real options we have here to minimize misconduct?
From the costs of rationality wiki:
Becoming more epistemically rational can only guarantee one thing: what you believe will include more of the truth . Knowing that truth might help you achieve your goals , or cause you to become a pariah. Be sure that you really want to know the truth before you commit to finding it; otherwise, you may flinch from it.
The reason that truth seeking is often seen as being integral to rationality is that in order to make optimal decisions you must first be able to make accurate predictions. Delusions, or false beliefs, are self-imposed barriers to accurate prediction. They are surprise inducers. It is because of this that the rational path is often to break delusions, but you should remember that doing so is a slow and hard process that is rife with potential problems.
Below I have listed three scenarios in which a person could benefit from considering the costs of truth seeking. The first scenario is when seeking a more accurate measurement is computationally expensive and not really required. The second scenario is when you know that the truth will be emotionally distressing to another person and that this person is not in an optimal state to handle this truth. The third scenario is when you are trying to change the beliefs of others. It is often beneficial if you can understand the costs involved for them to change their beliefs as well as their perspective. This allows you to become better able to actually change their beliefs rather than to just win an argument.
Scenario 1: computationally expensive truth
We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Yet we should not pass up our opportunities in that critical 3%. – Donald Knuth
If optimization requires significant effort and only results in minimal gains in utility, then it is not worth it. If you only need to be 90% sure that something is true and you are currently 98% sure that it is, then it is not worth spending some extra effort to get to 99% certainty. For example, if you are testing ballistics on Earth then it may be appropriate to use Newtons laws even though they are known to be inexact in some extreme conditions. Now, this does not mean that optimization should never be done. Sometimes that extra 1% certainty is actually extremely important. What it does mean is that you should be spending your resources wisely. The beliefs that you do make should lead to increased abilities to anticipate accurately. You should also remember occams Razor. If you are committing yourself to a decision procedure that is accurate, but slow and wasteful then you will probably be outcompeted by others who spend their resources on more suitable and worthy activities.
Scenario 2: emotionally distressing truth
Assume for a moment that you have a child and that you have just finished watching that child fail horribly at a school performance. If your child then asks you, while crying, how the performance was. Do you tell them the truth in full or not? Most people would choose not to and would instead attempt to calm and comfort the child. To do otherwise is not seen as rational, but is instead seen as situationally unaware, rude and impolite. Obviously, some ways of telling the truth are worse than others. But, overall telling the full truth is probably not going to be the most prudent thing to do in this situation. This is because the child is not in an emotional state that will allow them to handle the truth well. The truth in this situation is unlikely to lead to improvement and will instead lead to further stress and trauma which will often cause future performance anxiety, premature optimization and other issues. For these reasons, I think that the truth should not be expressed in this situation. This does not mean that I think the rational person should forget about what has happened. They should instead remember it so that they can bring it up when the child is in an emotional state that would allow them to be better able to implement any advice that is given. For example, when practicing in a safe environment.
I want to point out that avoiding the truth is not what I am advocating. I am instead saying that we should be strategic about telling potentially face-threatening or emotionally distressing truths. I do believe that repression and avoidance of issues that have a persistent nature most often tends to lead to exacerbation or resignation of those issues. Hiding from the truth rarely improves the situation. Consider the child if you don't ever mention the performance because you don't want to cause the child pain then they are still probably going to get picked on at school. Knowing this, we can say that the best thing to do is to bring up the truth and frame it in a particular situation where the child can find it useful and come to be able to better handle it.
Scenario 3: psychologically exhausting truth
If we remember that truth seeking involves costs, then we are more likely to be aware of how we can reduce this cost when we are trying to change the beliefs of others. If you are trying to convince someone and they do not agree with you, this may not be because your arguments are weak or that the other person is stupid. It may just be that there is a significant cost involved for them to either understand your argument or to update their beliefs. If you want to convince someone and also avoid the illusion of transparency, then it is best to take into account the following:
- You should try to end arguments well and to avoid vitriol - the emotional contagion heuristic leads people to avoid contact with people or objects viewed as "contaminated" by previous contact with someone or something viewed as bad—or, less often, to seek contact with objects that have been in contact with people or things considered good. If someone gets emotional when you are in an argument, then you are going to be less likely to change their minds about that topic in the future. It is also a good idea to consider the peak-end rule which basically means that you should try to end your arguments well.
- If you find that someone is already closed off due to emotional contagion, then you should try a surprising strategy so that your arguments aren't stereotyped and avoided. As elizer said here:
The first rule of persuading a negatively disposed audience - rationally or otherwise - is not to say the things they expect you to say. The expected just gets filtered out, or treated as confirmation of pre-existing beliefs regardless of its content.
- Processing fluency - is the ease with which information is processed. You should ask yourself if your argument worded in such a way that it is fluent and easy to understand?
- Cognitive dissonance - is a measure of how much your argument conflicts with the other persons pre-existing beliefs? Perhaps, you need to convince them of a few other points first before your argument will work. People will try to avoid cognitive dissonance. Therefore, it is better to start off with shared arguments and in general to minimise disagreements. It is often the sounder strategy to modify and extend pre-existing beliefs.
- Inferential distance - is about how much background information that they need access to in order for them to understand your argument?
- Leave a line of retreat - think about whether they can admit that they were wrong without also looking stupid or foolish? In winning arguments there are generally two ways that you can go about it. The first is to totally demolish the other persons position. The second is to actually change their minds. The first leaves them feeling wrong, stupid and foolish which is often going to make them start rationalizing. The second just makes them feel wrong. You win arguments the second way by seeming to be reasonable and non face threatening. A good way to do this is through empathy and understanding the argument from the other persons position. It is important to see things as others would see them because we don't see the world as it is; we see the world as we are. The other person is not stupid or lying they might just in the middle of what I call an 'epistemic contamination cascade' (perhaps there is already a better name for this). It is when false beliefs lead to filters, framing effects and other false beliefs. Another potential benefit from viewing the argument from the other persons perspective is that it is possible that you may come to realise that your own is not as steadfast as you once believed.
- Maximise the cost of holding a false belief - ask yourself if there are any costs to them if they continue to hold a belief that you believe is false? One way to cause some cost is to convince their friends and associates of your position. The extra social pressure may help in getting them to change their minds.
- Give it time and get them inspecting their maps rather than information that has been filtered through their map. It is possible that there are filtering and framing effects which mean that your arguments are being distorted by the other person? Consider a depressed person: you can argue with them, but this is not likely to be overly helpful. THis is because it is likely that while arguing you will need to contradict them and this will probably lead to them blocking out what you are saying. I think that in these kinds of situations what you really need to do is to get them to inspect their own maps. This can be done by asking "what" or "how does that make you" type of questions. For example,“What are you feeling?”,“What’s going on?” and“What can I do to help?”. There are two main benefits to these types of questions over arguments. The first is that it gets them inspecting their maps and the second is that it is much harder for them to block out the responses since they are the ones providing them. This is a related quote from Sarah Silverman's book:
My stepfather, John O'Hara, was the goodest man there was. He was not a man of many words, but of carefully chosen ones. He was the one parent who didn't try to fix me. One night I sat on his lap in his chair by the woodstove, sobbing. He just held me quietly and then asked only, 'What does it feel like?' It was the first time I was prompted to articulate it. I thought about it, then said, "I feel homesick." That still feels like the most accurate description--I felt homesick, but I was home. - Sarah Silverman
- Remember the other-optimizing bias and that perspectival types of issues need to be resolved by the individual facing them. If you have a goal to change another persons minds, then it often pays dividends to not only understand why they are wrong, but also why they think they are right or at least unaware that they are wrong. This kind of understanding can only come from empathy. Sometimes it is impossible to truly understand what another person is going through, but you should always try, without condoning or condemning, to see things as they are from the other persons perspective. Remember that hatred blinds and so does love. You should always be curious and seek to understand things as they are, not as you wish them, fear them or desire them to be. It is only when you can do this that you can truly understand the costs involved for someone else to change their minds.
If you take the point of view that changing beliefs is costly. Then you are less likely to be surprised when others don't want to change their beliefs. You are also more likely to think about how you can make the process of changing their beliefs easier for them.
Some other examples of when seeking the truth is not necessarily valuable are:
- Fiction writing and the cinematic experience
- When the pragmatic meaning does not need truth, but the semantic meaning does. An example is "Hi. How are you?" and other similar greetings which are peculiar because they look the same as questions or adjacency pairs, but function slightly differently. They are like a kind of ritualised question in which the answer is normally pre-specified or at least the detail of the answer is. If someone asks: "How are you" it is seen as aberrant to answer the question in full detail with the truth rather than simply with fine, which may be a lie. If they actually do want to know how you are, then they will probably ask a follow up question after the greeting like "so, is everything good with the kids".
- Evolutionary biases which cause delusions, but may help in perspectival and self confidence issues. For example, the sexual over perception bias from men. From a truth-maximization perspective young men who assume that all women want them are showing severe social-cognitive inaccuracies, judgment biases, and probably narcissistic personality disorder. However, from an evolutionary perspective, the same young men are behaving more optimally. That is, the bias is an adaptive bias one which has consistently maximized the reproductive success of their male ancestors. Other examples are the women's underestimation of men's commitment bias and positively biased perceptions of partners
tldr: this post posits that truth seeking should be viewed as an optimization process. This means that it may not always be worth it.
This is the first in a series of posts I am putting together on a personal blog I just started two days ago as a collection of my musings on astrobiology ("The Great A'Tuin" - sorry, I couldn't help it), and will be reposting here. Much has been written here about the Fermi paradox and the 'great filter'. It seems to me that going back to a somewhat more basic level of astronomy and astrobiology is extremely informative to these questions, and so this is what I will be doing. The bloggery is intended for a slightly more general audience than this site (hence much of the content of the introduction) but I think it will be of interest. Many of the points I will be making are ones I have touched on in previous comments here, but hope to explore in more detail.
This post is a combined version of my first two posts - an introduction, and a discussion of our apparent position in space and time in the universe. The blog posts may be found at:

What's all this about?
This blog is to be a repository for the thoughts and analysis I've accrued over the years on the topic of astrobiology, and the place of life and intelligence in the universe. All my life I've been pulled to the very large and the very small. Life has always struck me as the single most interesting thing on Earth, with its incredibly fine structure and vast, amazing history and fantastic abilities. At the same time, the vast majority of what exists is NOT on Earth. Going up in size from human-scale by the same number of orders of magnitude as you go down through to get to a hydrogen atom, you get just about to Venus at its closest approach to Earth - or one billionth the distance to the nearest star. The large is much larger than the small is small. On top of this, we now know that the universe as we know it is much older than life on Earth. And we know so little of the vast majority of the universe.
There's a strong tendency towards specialization in the sciences. These days, there pretty much has to be for anybody to get anywhere. Much of the great foundational work of physics was done on tabletops, and the law of gravitation was derived from data on the motions of the planets taken without the benefit of so much as a telescope. All the low-hanging fruit has been picked. To continue to further knowledge of the universe, huge instruments and vast energies are put to bear in astronomy and physics. Biology is arguably a bit different, but the very complexity that makes living systems so successful and so fascinating to study means that there is so much to study that any one person is often only looking at a very small problem.
This has distinct drawbacks. The universe does not care for our abstract labels of fields and disciplines - it simply is, at all scales simultaneously at all times and in all places. When people focus narrowly on their subject of interest, it can prevent them from realizing the implications of their findings on problems usually considered a different field.
It is one of my hopes to try to bridge some gaps between biology and astronomy here. I very nearly double-majored in biology and astronomy in college; the only thing that prevented this (leading to an astronomy minor) was a bad attitude towards calculus. As is, I am a graduate student studying basic cell biology at a major research university, who nonetheless keeps in touch with a number of astronomer friends and keeps up with the field as much as possible. I quite often find that what I hear and read about has strong implications for questions of life elsewhere in the universe, but see so few of these implications actually get publicly discussed. All kinds of information shedding light on our position in space and time, the origins of life, the habitability of large chunks of the universe, the course that biospheres take, and the possible trajectories of intelligences seem to me to be out there unremarked.
It is another of my hopes to try, as much as is humanly possible, to take a step back from the usual narratives about extraterrestrial life and instead focus from something closer to first principles. What we actually have observed and have not, what we can observe and what we cannot, and what this leaves open, likely, or unlikely. In my study of the history of the ideas of extraterrestrial life and extraterrestrial intelligence, all too often these take a back seat to popular narratives of the day. In the 16th century the notion that the Earth moved in a similar way to the planets gained currency and lead to the suppositions that they might be made of similar stuff and that the planets might even be inhabited. The hot question was, of course, if their inhabitants would be Christians and their relationship with God given the anthropocentric biblical creation stories. In the late 19th and early 20th century, Lowell's illusory canals on Mars were advanced as evidence for a Martian socialist utopia. In the 1970s, Carl Sagan waxed philosophical on the notion that contacting old civilizations might teach us how to save ourselves from nuclear warfare. Today, many people focus on the Fermi paradox - the apparent contradiction that since much of the universe is quite old, extraterrestrials experiencing continuing technological progress and growth should have colonized and remade it in their image long ago and yet we see no evidence of this. I move that all of these notions have a similar root - inflating the hot concerns and topics of the day to cosmic significance and letting them obscure the actual, scientific questions that can be asked and answered.
Life and intelligence in the universe is a topic worth careful consideration, from as many angles as possible. Let's get started.
