I listened to "The Demographics of Liberalism" on NPR, and noted a striking similarity between Phillip Longman's conclusions and those of Steve Sailer's Baby Gap research.

More from Longman in USA Today.

The main difference between Sailer and Longman appears to be their audiences.

While you're chewing on that, I wanted to pose a question: what could tax policy do to promote "eugenic" (for lack of a better word) reproductive trends? (Partial inspiration for this question.)
