.@Abebab Absolutely agree on that point! High heritability *within* groups does NOT imply mean diffs b/w groups are due to genetics

@WiringTheBrain@Abebab The higher the h2 within groups, the more likely that b/t-group diffs due to genes assuming G+E is the correct model1 reply 3 retweets 3 likes -

@pnin1957@Abebab No, not really. Mean diffs b/w pop'ns could be entirely environmental, even with high h2:pic.twitter.com/8IOFXV3ePi

@WiringTheBrain@Abebab Yes, they could be, but high h2 increases the probability that genes contribute to b/t-group diffs.2 replies 1 retweet 2 likes -

@WiringTheBrain@Abebab If H=90% but E explains group diff, then everyone in lower group must have worse envrment, which is rare outside lab1 reply 2 retweets 3 likes -

@WiringTheBrain@Abebab Perfectly disjoint distributions of envr effects exist only in lab, not between groups (within societies).3 replies 4 retweets 3 likes -

@smomara1@WiringTheBrain@Abebab I would bet anything that that difference is not 100% environmental.1 reply 0 retweets 2 likes
@WiringTheBrain as a complete aside, have you read that iq study from the 1970s? i have yet to track down anyone who has, except r. lynn.
