Frank regretfully missed an important deadline at work. his boss, george, thinks to himself, "frank missed that deadline because he is lazy; i really need to crack down on him more." this is an example of what kind of attribution?

I believe the answer is: internal attribution

Internal attribution refers to a situation when an individual use personal reason to explain the situation that happen to them.

This type of reasoning tend to be extremely subjective and resulted in biased interpretation that does not represent the truth.
