comment Is Decision Making/Theory/Analysis applicable to game design?
OK, I see. However, it that case there are many other psychological things - including feedback you get. So it's more in psychology of games and of learning, than pure decision-making. However I doubt if, from a general point of view, one can say something more than "it shouldn't be to obvious or too random, and one should learn something by reaction (of the environment or opponent) if the decision was good".

comment Is Decision Making/Theory/Analysis applicable to game design?
What do you mean by the decision making in game? Could you provide an example? But as a general comment, for practical issues in soft sciences most of the time practice beats theory. Maybe the latter can be an inspiration (e.g. I saw a paper on how to design a FPS level to make someone feel overwhelmed, when going back and forth in We don't go through Ravenholm in Half-Life 2; I cannot find it now though).

comment How similar are human brains within the same haplogroup?
And what do you want to compare? Different skills (e.g. verbal intelligence), different anatomy, different neurochemistry?

comment What stimulus features determine the psychophysical power law exponent?
@Jake It's not that unlikely that for some it's "so obvious, there is no point of writing a paper about it" and the others are not aware of that issue (anyway, it requires a certain proficiency in natural sciences), with not that many in between. But hey - maybe there is place for you to clarify. Are you writing a paper when you want to refer to material of the question that you asked?

comment What stimulus features determine the psychophysical power law exponent?
I don't know psychological papers on it. But well, it's fundamental stuff and the Nature does not care if psychologist know it or not. (Compare as if some guys used 2+2=5 claiming "hey, but there is no paper in our field disproving that".) I know some well more subtle papers (e.g. arXiv:1102.4101 when it is argued that a certain statistical relation in data-drive sociology is not necessary a power law). Also, I bet that most of mathematical psychologists know are very well aware of it. Sadly, I have doubts whether standard psychologists are enough educated.

Now I'm away from may books, but it should be is something like "Feynman lectures on physics" or, if you want something more specific, look at dimensional analysis (there you see very well that also the constrains change relations drastically).

comment What stimulus features determine the psychophysical power law exponent?
Well, it's a piece of any standard physics introduction that: you cannot compare different variables (e.g. what is more: one meter or one kilogram) unless you have relations between them. And both depending on the choice of variables, and of the constrains, you obtain vary different relations between "physical quantities". For example, take "heat" as a function of "electricity" - i takes no sense. Even if restrict ourselves to "heat" = energy generated per second (W), (I - current, U - voltage, R - resistance) then it can be W(U) = I U, W(U) = U^2/R, W(I) = I U, W(I) = R I^2, ...

Just of todays findings: "Cooooooooooooooollllllllllllll!!!!!!!!!!!!!! Using Word Lengthening to Detect Sentiment in Microblogs" (I haven't it yet, but its title is so charming that I didn't the urge to post it here).

comment When faced with a choice and trying to make a quick decision, are 2 options better than 3 or more options?
What do you mean by better? Faster to choose, with higher utility (how defined?), causing less doubts during the choice, causing less doubts after the choice...? And, what is the 3rd option (better, worse, different) for 2 others? (Otherwise a great question, BTW.)

comment Is religiousness a genetically heritable feature?
@Xurtio Answers can be improved. So just if you copy and paste your comment, it would be beneficial. Bear in mind that comments are to improve a question. For answers (also - partial) - there are... answers.

BTW: Do people with high agreeableness agree with more statements (positive or negative, or at least: positive) than ones with low agreeableness?

comment Why do humans have sex in private?
@Tiberiu-IonuțStan First, I know a bunch of illegal things (e.g. drinking in public in my country) that popular. Second, there is not a single issue I'm 100% sure about. If you are 100% sure, please consider putting your money where your mouth is and write an well-supported answer saying it's a cultural thing, not a biological one.

comment Why do humans have sex in private?
@Tiberiu-IonuțStan No, the question is not about law, obeying it etc. It is about a one or two layer deeper thing. Needless to say, there are many positive feedback loops.

Anyway, why so downvoted? While I'm not convinced, the answer is far from from being "not useful". (Perhaps a long time ago sex was dirty.)

@DavidWiner I'm not disgusted by pubic hair nor genitals (as long as they are clean, healthy, perhaps young - and for that traits your explanation works).
