If people are aware of their hidden biases, they can monitor and attempt to ameliorate hidden attitudes before they are expressed through behavior. This compensation can include attention to language, body language and to the stigmatization felt by target groups.

Common sense and research evidence also suggest that a change in behavior can modify beliefs and attitudes. It would seem logical that a conscious decision to be egalitarian might lead one to widen one's circle of friends and knowledge of other groups. Such efforts may, over time, reduce the strength of unconscious biases.

It can be easy to reject the results of the tests as "not me" when you first encounter them. But that's the easy path. To ask where these biases come from, what they mean, and what we can do about them is the harder task.

Recognizing that the problem is in many others — as well as in ourselves — should motivate us all to try both to understand and to act.
