face-palm Ah yes. Thanks.

I'm not sure I see your point. My reasoning was that if you meet the same person on average every thousand games in an infinite series of games, you'll end up meeting them an infinite number of times. Am I confusing the sample space with the event space?

If you have a strong discount factor, then even if you meet the same person infinitely often, your gain is still bounded above (summing a geometric series), and can be much smaller than winning your current round.

I seem to remember more elaborate techniques that I think were trying to capture genetic drift and selection, but I can't find them at the moment.

A quick google along the lines of "mathematical model meme propagation" does tend to pop up quite a few models. Here are two that seemed interesting: http://cogprints.org/531/1/mav.htm and http://cfpm.org/jom-emit/2000/vol4/kendal_jr&laland_kn.html

So, perhaps start with my references. Interesting models started in the 1970s, and there were three books on the topic in the early 1980s: * Lumsden, C. and Wilson, Edward O. (1981) Genes, Mind, and Culture. * Cavalli-Sforza, L. L. & Feldman, M. W. (1981) Cultural transmission and evolution: A quantitative approach. * Richerson, Peter J. and Boyd, Robert (1985) Culture and the evolutionary process. Since then the field has exploded. The article Mathematical Models for Memetics explains how this material relates to memetics.

Could you elaborate on that?

Consider the question: "Where did that viral video come from - why that video and not another video?" - That's the colloquial use of meme, but it's not a very useful question because the answer often "Random chance at the intersection of timing and relevance." Consider the different question "When did it become unacceptable for males to have intimate friendships with other men?" Looking at the source of that, including with other ideas supported its creation and continuance - is essentially the only useful aspect of analysis of memes.

Memetics consists of terminology and framework for cultural evolution. Cultural evolution covers a lot of hypotheses. For instance there's the hypothesis that the human brain swelled up to accommodate memes or the hypothesis that memes made humans sociable - since they need social contact between their hosts in order for them to reproduce - or they hypothesis that memes were implicated in the high frequency of speciation among our ancestors - just as songbirds speciate frequently. There's quite a lot of associated hypotheses - no doubt some are correct and some are not.

Thanks for this! I've really found it helpful.

I suppose part of my confusion came from reading in Eyesenck about the alarmingly large number of geniuses that scored as prodigies, but over a longitudinal study, ended up living unhappy lives in janitor-level jobs. Eyesenck deals with this by discussing correlations between intelligence and some more negative personality traits, but I would have expected great enough intelligence to invent routines to compensate for that. In any case, I think this points to my further being confused about how 'success' was being defined.

I'm also puzzled at the apparent disconnect between solving problems in one's own life and solving problems on paper.

The citations in this comment are new science, so please take them with at least a cellar of salt:

There are recent studies, especially into Wernicke's area, which seem to implicate alternate areas for linguistic processing : http://explore.georgetown.edu/news/?ID=61864&PageTemplateID=295 (they don't cite the actual study, but I think it might be here http://www.pnas.org/content/109/8/E505.full#xref-ref-48-1); and this study (http://brain.oxfordjournals.org/content/124/1/83.full) is also interesting.

In my own experience, self skepticism isn't sufficient. It's bloody useful of course, but it's also an exceptional time sink -- occasionally to the point where I'll forget to actually think of solutions to the problem.

Does anyone have any algorithms they use to balance self-skepticism with actually solving the problem?

Use more concentrated and in-depth self-skepticism for positions that affect more of your life. For example, I spend a great deal of time criticizing my own ethical beliefs because they significantly affect my actions.

Hi all,

Long time lurker, first time poster. I've read some of the Sequences, though I fully intend to re-read and read on.

I'm an undergrad at present, looking to participate in a trend I've been observing that's bring some of the rigor and predictive power of the hard sciences to linguistics.

I'm particularly interested in how language evolved, and under what physical/biological/computational constraints; What that implies about the neural mechanisms behind human behavior; and how to use those two to construct a predictive and quantitative theory of lingui... (read more)

I think, more to the point is the question of what functions the evolutionary processes were computing. Those instincts did not evolve to provide insight into truth, they evolved to maximize reproductive fitness. Certainly these aren't mutually exclusive goals, but to a certain extent, that difference in function is why we have cognitive biases in the first place.

Obviously that's an over simplification, but my point is that if we know something has gone wrong, and that there's conflict between an intelligent person's conclusions and the intuitions we've e... (read more)
