When a supervisor evaluates the performance of an employee and shows a tendency to assign too much credit to the employee for his or her successes and too much blame to the employee for his or her failures,this is a demonstration of the ______.

A) fundamental attribution error
B) actor-observer difference
C) the halo effect
D) the similar-to-me effect

The fundamental attribution error is a cognitive bias that involves attributing other people's behaviors to internal factors (such as their personality or abilities) rather than considering external factors (such as situational or contextual variables). In this case, the supervisor is exhibiting this bias by attributing the employee's successes to their abilities and failures to their shortcomings, rather than considering external factors that might have contributed to them.
