Answer:
The answer is the actor-observer effect.
Step-by-step explanation:
This bias takes place when a person attributes their own outcomes to situational causes, and others' to internal causes. This is mot common with negative outcomes.
The actor-observer effect is thought to occur because we are directly observing the behaviour of others, while we can't do the same with ourselves (we can only observe our environment). For this reason, we focus more on other people's personal traits.
