None of us is immune to bias. From our education systems to our justice systems, bias exists in many forms. Where does it originate and what can we do to prevent it? The answers aren’t simple. In this article by psychologist Jill Suttie, the root causes of bias are explored through the lens of researcher Jennifer Eberhardt’s new book, Biased. Suttie considers how our implicit bias is at times adaptive, and while it’s difficult to eliminate altogether, we can increase our awareness of its presence and better understand its impact in our interactions and institutions.
