Relation of confidence and problem solving ability My personal experiences have shown me multiple times that by only boosting my confidence in my ability to solve a problem,  without gaining any additional knowledge, I was able to solve it!

My question is, has this been studied that to what extent our confidence in our abilities can help us to find a solution for a problem?

If so, can you please provide a link?

A brief Google search show cases where this occurred. For example, it seems that a study on medical students showed a significant relationship between confidence and ability after training, although not before training (Clanton et al., 2014). This being said, the Dunning-Kruger effect always comes to mind when such questions come up…
