Identity styles and hypothesis-testing strategies.

The author investigated the manner in which individuals with different identity styles evaluate information relevant to a trait hypothesis-testing task. Identity style refers to how individuals seek, process, evaluate, and use self-relevant information. In a sample of U.S. college students, the participants with normative identity styles displayed confirmatory biases that served to protect and preserve the hypothesis being evaluated. The students with informational identity styles also used confirmation-biased hypothesis-testing strategies. The participants with diffuse-avoidant styles did not discriminate between confirmatory and disconfirmatory information.
