Curiosity is something that always interests me. I have written about it in the past, but was drawn to looking at it again recently. There are several theories about what curiosity is and how it works; Curiosity Drive Theory, Optimal Arousal Theory, Incongruity Theory and probably more. They all deal with different aspects of what curiosity is.
Drive Theory considers that curiosity is part of a human need to reduce the discomfort felt when we are uncertain about somemthing.
Incongruity Theory suggests that we seek to resolve incongruity (differences) between something that happens and our existing understanding. So if something happens that doesn’t match our preconceived ideas of what should happen, we become curious and want to understand it.
