Twin studies bear this out. It is sometimes suprising how similar twins separated at birth are, even though they had very different cultural upbringings.  So E.O. Wilson's rejection of tabula rasa was correct, and the "International Committee Against Racism" was over-the-top, cocksure and wrong.

Yet if you search the Internet for E.O. Wilson you'll find many writings about how he was a bad man, how he promoted "scientific racism."

The modern (mostly American) movement to reject inconvenient truths and replace them with desires (for that is my best description of what is going on) is naturally detrimental and destructive and is the root cause of America's slow but inexorable downfall.
