Heather Mac Donald joins City Journal associate editor Seth Barron to discuss the dubious scientific and statistical bases of the trendy academic theory known as "implicit bias." The implicit association test (IAT), first introduced in 1998, uses a computerized response-time test to measure an individual's bias, particularly regarding race.

Despite scientific challenges to the test's validity, the implicit-bias idea has taken firm root in popular culture and in the media. Police forces and corporate HR departments are spending millions every year reeducating employees on how to recognize their presumptive hidden prejudices.

Heather discusses the problems with implicit bias, the impact that the concept is having on academia and in the corporate world, and the real reasons for racial disparities in educational achievement and income levels.
