Integration, by itself, has not been shown to produce dramatic changes in attitudes and behavior. But many studies show when people work together in a structured environment to solve shared problems through community service, their attitudes about diversity can change dramatically.

By including members of other groups in a task, children begin to think of themselves as part of a larger community in which everyone has skills and can contribute. Such experiences have been shown to improve attitudes across racial lines and between people old and young.

There also is preliminary evidence that unconscious attitudes, contrary to initial expectations, may be malleable. For example, imagining strong women leaders or seeing positive role models of African Americans has been shown to, at least temporarily, change unconscious biases.
