Average IQ seemed insane to me. Thanks for dealing extensively with that objection.

With only 500 people responding to the IQ question, it is entirely possible that this is simply a selection effect. I.e. only people with high IQ test themselves or report their score while lower IQ people keep quiet.

Even I was disappointed by the correlations between P(significant man-made global warming) vs. e.g. taxation/feminism/etc. Most other correlations were between values, but this one was between one's values and an empirical question. Truly Blue/Green.

There's nothing necessarily wrong with this. You are assuming that feminism is purely a matter of personal preference, incorrectly I feel. If you reduce feminism to simply asking "should women have the right to vote" then you should in fact find a correlation between that and "is there such a thing as global warming", because the correct answer in each case is yes.

Not saying I am necessarily in favour of modern day feminism, but it does bother me that people simply assume that social issues are independent of fact. This sounds like "everyone is entitled to their opinion" nonsense to me.

What I find more surprising is that there is no correlation between IQ and political beliefs whatsoever. I suspect that this is simply because the significance level is too strict to find anything.

Given that LW explicitly tries to exclude politics from discussion (and for reasons I find compelling), what makes you expect differently?

With this, on the other hand, I agree completely.
