The evidence that most human traits are highly heritable — not just obvious physical traits, mind you, but cognitive and behavioral qualities and dispositions as well — is accumulating rapidly, and will soon be overwhelming. (In scientific terms it already is, but what is about to be overwhelmed is the nurturist and culturist dogma that has formed the foundation of the modern social sciences, and that has been the basis of half a century of completely ineffectual, and often disastrous, public policy.)

Charles Murray has called this an “unstoppable train” that would be arriving within the next three years. How long it will be before “race is a social construct” is replaced in public discourse by the far more plausible “societies are racial constructs” is anybody’s guess, but I’d say this item from the Boston Globe is a sign that the rails are beginning to vibrate.
