Just FYI, Jonathan Haidt is not very conservative (if at all) either. Nor is Steven Pinker, who holds quite similar views. BTW, I am left liberal (although not American) and I agree with Pinker, Haidt and Jussim (in fact I very much enjoyed his articles on the topic that are quoted in the OP). I think many liberals in the U.S. should accept the fact that yes, men and women have different job preferences (regardless whether this is due to culture or nature, I think it's a mix of both), and there is nothing wrong with that. What is really important is that people, who really want to work in some field, can. And personally, I am not sure how many people who opposed The Google Memo I can actually consider to be leftists. To be on the left means to care first and foremost about underprivileged people, and almost no Google employee simply fits that category (maybe a cleaning lady or a security guard, but I am pretty sure they are outsourced).
