Not recognizing what the rules are or not understanding why they exist could be more easily confused with non-conformity, while recognizing the rules but failing to apply them is more apparently incompetent. Volitional non-conformity requires understanding of the rules and the ability to apply them, and it's not entirely obvious what constitutes understanding in this highly subjective matter. The aspect of opting in/out of acquiring the skills needed for conformity complicates things further.

Lots of late night computer screen time? That blue light is messing with sleep cycles. I used to think I'm a night owl myself but can adjust my sleep schedule at will if I just mind the lighting. These days I wake up at 2-4am.

Curiously all males in my family used to be late sleepers when young but effortlessly switched to rising early when their careers kicked off. They didn't have computers back then so maybe it was their social lives keeping them up late.

the question under discussion here is what actually is the placebo effect and how much of it can you attribute to psychosomatic factors and how much to just regression to the mean (aka natural healing).

In that case your opener is slightly polemical :)

But that doesn't mean that we couldn't or shouldn't ask questions about the placebo effect itself.

Agreed. The problem with nonintervention arms for studying the placebo effect is that there aren't clear incentives for adding them and they cost statistical power.

The placebo group is called such because it receives the placebo treatment, not because medical researchers think all improvement in it is attributable to the placebo effect. Results are reported as improvement in the treatment arm vs. the placebo arm, and never have I seen these differences explicitly reported as treatment effect vs. placebo effect, and I've read hundreds of medical papers. The real magnitude of the placebo effect is almost never of interest in these papers. Some professionals in the medical community could have such a misconception because of the usual lack of scientific training, but I'd like to think they are a small minority.

If the placebo effect is of real importance, I think a more significant problem would be the lack of use of active placebos that mimick side effects since most drugs have them and this is a potential source of breaking the blinding of RCTs.

Whatever the terminology, they should make the connection between the process of decision making and the science of decision making, which they don't seem to do. Medicine is like this isolated bubble where every insight must come from the medical community itself.

I found overcoming bias and became a rationalist during med school. Finding the blog was purely accidental, although I recognized the need for understanding my thinking, so I'm not sure what form this need would have taken given a slightly different circumstance.

We were taught bayes in the form of predictive values, but this was pretty cursory. Challenging the medical professors' competence publicly isn't a smart move careerwise, unless they happen to be exceptionally rational and principled, unfortunately.

Huh. My experience is somewhat similar to yours in the sense that I never was a big fan of memorization, and I'm glad that I could outsource some parts of the process to Anki. I also seem to outperform my peers in complex situations where ready made decision algorithms are not available, and outperformed them in the few courses in medschool that were not heavy on memorization. The complex situations obviously don't benefit from bayes too much, but they benefit from understanding the relevant cognitive biases.

The medical degree is a financial jackpot here in Finland, since I was actually paid for studying, and landed in one of the top 3 best paying professions in the country straight out of medschool. Money attracts every type, and the selection process doesn't especially favor rationalists, who happen to be rare. It just baffles me how the need for rationality doesn't become self evident for med students in the process of becoming a doctor, not to mention after that.

More apps for Android (5.0.2):

Alarm clock plus - probably the most feature rich alarm bell app. It allows for multiple alarms on different days with different tones, alarm labels, gently rising alarm, quick to set one time alarms and alarms that won't stop unless you solve a math problem which is useful for deep sleepers.

Clockwork Tomato - a fully customizable pomodoro timer.

Darker - pretty much the same as Night Mode, except that it also allows for color adjustment. Unfortunately Android doesn't seem to support dimming certain wavelengths and the color is just slapped over everything (the strength is adjustable), so the contrast isn't that great.

I think what sets the above mentioned ES File Explorer above others is the integrated networking capability, you can use cloud storage, FTP and LAN sharing with the same app.

FBReader with TTS Plugin - listen to .epub and .mobi formatted ebooks.

Libra - weight tracking with charts, weight loss goal tracking, statistics on weight change and excess/shortage of calories.

Pocket - put articles you find during browsing to a safe place for later reading. It has a browser extension on PC for Firefox and Chrome and sync capability. Also, it has a page flipping mode that allows reading articles as if you were reading an ebook, and inverted color rendering for night time reading.

Repligo PDF Reader - I think I've tried every pdf reader there is on Android, and this is the only one that can both reliably reflow text for easier readability and has inverted rendering. Also has a text-to-speech option.

Rittr Labs Push Ups, Sit Ups, Pull Ups and Squats - All of the four apps are separate but I haven't found a better app for automatically generated calisthenics workouts. These calculate the first workout sets based on your max repetitions and the next workout based on how people usually progress, which is further adjusted by telling the program whether the workout was too hard, just right or too easy. I'd recommend you give at least a day or two for recovery between workouts, for example have a different workout for each day with a four day rotation.

The whole point of the renormalization group is that lower level models aren't more accurate, the lower level effects average out.

I tried to read about RG but it went way over my head. Is the universe in principle inexplicable by lower level theories alone according to modern physics? Doesn't "averaging out" lose information? Are different levels of abstraction considered equally real by RG? Does this question even matter or is it in the realm of unobservables in the vein of Copenhagen vs MW interpretation?

EDIT: this is now pretty much retracted, see the following thread.

If the reductionist thesis is "we use multi-level models for computational reasons, but physical reality has only a single level", then what kind of evidence could support it against the thesis "we use multi-level models for computational reasons AND physical reality has multiple levels?"

Lower level models are more accurate than abstract models, and you can observe the consequences of this on multiple levels of abstraction. Therefore if physical reality has multiple levels then they must be incompatible and parallel in a very peculiar way. This makes the idea more complex and therefore less probable than the reductionist thesis.

Tabooing reality might make things a bit clearer.

I assume that by evolution you mean biological evolution specifically, since the general mechanics of any evolution can be accurately described in a few sentences after reading The Selfish Gene. People here could probably write a program in a couple of lines of code that fits the bill.

If you want to simulate biological evolution, the simplest form of it would be in the realm of bacteria, and I'd search books about bacteriology and bacterial evolution. Any introductory text in cell biology will describe how genes are copied and expressed and how mutations work. I predict you'll be painfully surprised by the complexity of the specifics.

Quality observational research is probably very difficult to do since you can't properly control for indirect cognitive benefits you get from learning a second language and I'd take any results with a grain of salt. You also can't properly control for confounding factors e.g. reasons for learning a second language. I think you'd need experimental research with randomization to several languages and this would be very costly and possibly inethical to set up.

I have without a question gotten a huge boost from learning English since there aren't enough texts in my native language about psychology, cognitive science and medicine that happen to be my main interests. My native language also lacks the vocabulary to deal with those subjects efficiently. I have also learned several memory techniques and done cognitive tests and training solely because of being fluent in English.

Much of the effect you attribute to training is likely just maturation of the brain. There's going to be a lot of natural improvement in cognitive functions until your son reaches his 20s.

That was a wonderfully clear introduction! I'd definitely want to see more posts on sleep since I think it's one of the most important, if not the most important aspect of optimizing cognitive performance.

I second Mirzhan_Irkegulov's disinterest in polyphasic sleep though, at least until several lower hanging fruits have been picked. Polyphasic sleep is likely to be excessively difficult to maintain by most people, even if it were a viable alternative. Since sleep is enormously important as you stated and likely interesting as it is to many people, your posts will have a greater positive impact if you explore the less niche venues first.

Most people in society follow the same sleeping patterns so I can't see why disabling circadian control at will would be extremely useful unless you do shift work or have to socialize at nights. Could expand on that? I think it's much easier to not get sleep deprived in the first place. Problems of shift work are increasingly mitigated by the internet as work is computerized and thus can be done by people on the sunny side of the planet while you sleep.

I fail to notice flaws in them I would notice with a sober mind, and when I do notice flaws I accept flaws I wouldn't normally accept. Since being in love feels so good, much of my thinking is dedicated to reinforcing my feelings through imagining situations with the person when they're not around and of course nothing in those situations ever goes wrong. This creates unrealistic expectations. I plan my life with them optimistically way further than I would plan my life in any other regard.

I don't know if being "in love" is a thing that actually exists

What do you mean? There's a word called love and there's a reality that people refer to with the word. Words are replaceable.

I'd like to know if it corresponds to an internal state that I have experienced.

The problem is the same hormonal process doesn't necessarily feel exactly the same in everyone's body. I think it would be more reliable to inspect your thoughts and your behavior towards the person and compare them to other people in love.

In particular, how does romantic love differ from friendship?

That's like asking how hot differs from cold, perhaps equally inexplicable, if you're asking about being in love. If you would've experienced it, you'd know. More reasonable people look mainly for friendship in their life partners and therefore might use the words love and friendship interchangeably. They probably wouldn't talk about being in love however.

As a data point I've been in love several times, also reciprocically. It hasn't made me happier on the whole, since the state makes me short sighted and neglect more lasting sources of happiness, and therefore I'm not seeking it anymore.

The standard quick-and-dirty method of predicting others seems to be "model them as slightly modified versions of you"

It certainly doesn't feel that way to me, but I might have inherited some autistic characteristics since there are a couple of autistic people in my extended family. Now that I've worked with people more, it's more like I have several basic models of people like "rational", "emotional", "aggressive", "submissive", "assertive", "polite", "stupid", "smart", and then modify those first impressions according to additional information.

I definitely try not to model other people based on my own preferences since they're pretty unusual, and I hate it when other people try to model me based on their own preferences especially if they're emotional and extroverted. I find that kind of empathy very limited, and these days I think I can model a wider variety of people than many natural extroverts can, in the limited types of situations where I need to.

The hippocampus is a relatively tiny structure in the human brain, and I would guess it's even proportionally smaller in the mouse brain.

Do you compare only the responses of the same person at different times

Yes. There's too much variation between persons. I also think there's variation between types of pain and variation depending on whether there are other symptoms. There are no objective specific referents but people who are in actual serious pain usually look like it, are tachycardic, hypertensive, aggressive, sweating, writhing or very still depending on what type of pain were talking about. Real pain is also aggravated by relevant manual examinations.
