In a blog post we put out a few weeks ago, we discussed “blind hiring,” a trending new hiring practice that some employers are using to mitigate the effects of unconscious bias. Unconscious bias refers to the mental shortcuts and stereotypes we use unconsciously when judging situations and making decisions. While the concept of unconscious bias is widely accepted in psychology, many people may find it hard to believe that their everyday decisions are regularly influenced by unconscious bias.
Last summer we reacted to an interview with Laszlo Bock at Google who seemed to say that tests scores and grades were useless predictors for hiring decisions. We said that what constitutes information for hiring purposes at Google may well differ from what constitutes information for hiring elsewhere, and we pointed out that validating a selection tool after it has been used, and only for those who were selected will typically yield lower estimates of the usefulness of that tool.
