The trainee hiring bias described as appraisers hiring trainees from their own ethnic group is an example of which bias?

• A. Out-group bias
• B. In-group bias
• C. Confirmation bias
• D. Halo bias

Answer: (B)

In-group bias is at play here—the tendency to favor members of your own group. When appraisers hire trainees who share their ethnic background, they’re preferring people who are like them, which is the hallmark of in-group bias.

Out-group bias would involve bias against those outside the group, which is not what's described. Confirmation bias is about favoring information that supports preconceptions, not about who gets hired. Halo bias would involve letting an overall positive impression of someone influence judgments about their specific traits, which isn’t the scenario described.
