interesting discussion. but regarding 99%, I know of no environmental manipulation which can explain that much of individual differences. it's not just about reliability, it's also about explaining all the variance - two different things.

if the memes cause effects in the presence of certain trivial traits caused by genes then that issue is solved, isn't it? the genes work as predictors like the study thinks, but don't actually do much of anything.
