social dynamics
You believe you contributed more than others did.
The egocentric bias leads you to overestimate your own input in collaborative efforts.
Researchers have found that in many partnerships, the sum of individual estimates of contribution consistently exceeds 100%. Because you have better access to your own internal struggle and effort than your partner's, you assume your work was more significant. You are an expert in your own exertion and a stranger to the work of others.
You are the center of your own effort.
