Daniel A. Yudkin and Jay Van Bavel describe the experiments they ran and the conclusions they reached about implicit bias.
“But implicit bias is not about bigotry per se. As new research from our laboratory suggests, implicit bias is grounded in a basic human tendency to divide the social world into groups. In other words, what may appear as an example of tacit racism may actually be a manifestation of a broader propensity to think in terms of “us versus them” — a prejudice that can apply, say, to fans of a different sports team. This doesn’t make the effects of implicit bias any less worrisome, but it does mean people should be less defensive about it.
Furthermore, our research gives cause for optimism: Implicit bias can be overcome with rational deliberation.”
