No matter how highly you think of your organization, chances are its members—including you—are biased in ways that harm both you and others. Decades of research tell us that systematic errors affect our judgments and decisions at work, as well as the way we interact with others. And some of these biases are unconscious, including racial, gender, and income discrimination. The consequences of such insidious biases can be quite costly to an organization, from leading it to hire or promote the wrong candidates to investing in less innovative ideas just because of who proposed them to crossing ethical boundaries.
