Cathy has long believed that all her supervisors are cranky and disagreeable individuals. According to the confirmation bias, after being transferred to a new department, what will Cathy most likely do on her first day in the new supervisor's department?

She will look for negative behavior from her supervisors.

Confirmation bias is when a person (unconsciously or consciously) automatically searches for information that supports their previous beliefs or knowledge. In Cathy's case, she has had a history of all of her supervisors being negative people. She will then expect her new supervisors to also be negative, falling into confirmation bias.
