Intelligence and religiousness in OKCupid dataset

Miron Zuckerman is updating his meta-analysis of the religion and intelligence relationship, and asked me to compute some extra analyses of the OKCupid dataset.

Results: http://rpubs.com/EmilOWK/intell_religion_OKCupid

Main findings

Cognitive ability is independent cause of the usual demographics.

Distribution of cognitive ability by religious stance x seriousness. Error bars = 95% confidence intervals.

Gays more religious than bisexuals? Weird. Female bisexuals less than heterosexual men? Smells of sampling bias, but maybe not.
