> Point me to where Luke denied that academia has any advantages over LW. If you're going to claim that LW is obviously not "the highest-quality relatively-general-interest forum on the web", it would help your case to provide an obvious counterexample (academic channels themselves are generally no...(read more)

The colloquial definition is "Useless but impressive and flatters my vanity".

The probabilistic definition is "Observable thing X signals quality A means P(A|X) > P(A)".

The economic definition is "Alice signals P to Bob by X if the net cost of X to Alice is outweighed by the benefits of Bob 'bel...(read more)

The definition of limit: "lim x -> a f(x) = c " means for all epsilon > 0, there exists delta > 0 such that for all x, if 0 < |x-a|<delta then |f(x) - c| < epsilon.

The definition of derivative: f'(x) = lim h -> 0 (f(x+h) - f(x))/h

That is, for all epsilon > 0, there exists delta > 0 such that f...(read more)

I'm open to coworking generally.

My ideal coworker is someone who is funny and interested in maths, physics and computer science. My plan would be to read books like Mathematics Form and Function or The Feynman Lectures on Physics and try to summarize / explain the content. For co working where I s...(read more)

You're accusing me of group selectionism? We might disagree on a point of terminology, but come on, I'm not a completely nutter. Anyway, my point in quoting the wikipedia article is that too much dishonest signalling makes signalling completely pointless ('weakens the integrity of the signalling sys...(read more)

No. I think that because lying is common in human society, a credible signal must be costly to liars.

Well I'm happy to use "costly signalling". I was under the impression that costly signalling was signalling. If it isn't costly, at least for potential fakes, then I'm not sure how it can serve as an explanation for behavior. Why should I signal when the fakes can signal just as easily? What is ther...(read more)

A rube is a sucker, someone easily deceived.The slogan means that potential signalling explanations shouldn't assume that the receiver of the signals is stupid.

Why not? Can't we regard evolutionary signalling as completely analogous to cognitive signalling, just as played by genes over a much longer time scale?
