Appropriately enough just today Big Questions Online has a story about why some people are more willing to confront prejudice than others. Here’s a key section:

Obviously, there are a number of factors involved here, but one of them, they say, is how we think about personality. Those of us who hold an “incremental” view of personality—who believe it is malleable and can change over time—are more likely to confront prejudice than those who believe people have fixed personality traits—what’s called the “entity” view.

And then they provide a link to the study. Well worth reading.
