update: I forgot to post my amended picture:
Steven Pinker’s latest apology for behavioral genetics is in this weekend’s NYT Magazine. There are two things to pay attention to. 1) he’s right about personal genome sequencing: regardless of whether it’s correct, or the results can be properly interpreted for people, people are going to do it, and for all kinds of reasons, good and bad, and this is in itself something that will change behavior–call it proximate causality for individual behaviors. And the comparison with astrology, sorcery and other forms of readouts about your fate should probably be taken more seriously, especially by anthropologists, rather than used as a dismissal of genetic essentialism or determinism. 2) genetics seems to have become so confused with heritability that the claims about “what genes cause” have become incoherent; scales are routinely mixed up, which is what results in the manic fantasizing about why we conserve one gene or another (“gene so-and-so is correlated with baldness, therefore baldness must have conferred an advantage on our distant ancestors by serving as an effective way to deflect light before mirrors were invented” etc). As a result, our ability to argue about the roles that distant causality play versus those that proximate causality play have been compromised. Oh, and one other thing, There is no mention at all of epigenetics… is that deliberate, I wonder, or does it represent troubling ignorance on Pinker’s part?
and btw, I will note that our category for genetics at SM is “Race, genetics” which (and I’m not blaming anyone here) is interesting.
