Research on biased information seeking demonstrates that after decisions, people show a preference for supporting rather than conflicting information (confirmation bias). In a laboratory study (N = 86 German undergraduates), we examined the interactive effects of different decision types and gender on the confirmation bias. Our study revealed that women showed less confirmation bias when the decision concerned themselves and their mate (interdependent decision) compared to a decision concerning only themselves (independent decision). In contrast, men showed less confirmation bias when they made an independent compared to an interdependent decision. Results were discussed in terms of self-construal differences between men and women leading to different motivations (defense vs. accuracy) during the information seeking depending on the decision type.
