Erika’s new caller continued, “Not that I think we deserve all the blame. Our son would have talked to us if he hadn’t been hanging out with a bad crowd. All of his friends just act without thinking. I guess their parents raised them differently, but I wish they didn’t affect my son so much. Especially his new best friend. He gets good grades, but I think that’s because the teachers take it easy on him, or that he cheats well.”
The caller’s statement indicates that she is affected by attribution bias in believing that her son’s friend does not succeed at school because of his abilities, but rather because of external factors.
