Hi everyone. My plane is boarding for Aotearoa, so apologies for any errors or clumsy wording in this post.
When I was in high school, I took AP Psychology. A few weeks into the class, my teacher, Mr. Henderson, approached me to ask how I was doing in class. I said I didn’t think I was doing OK, that I was nervous about the AP exam, and that I was afraid I would fail it.

The Dunning-Kruger effect is basically this (though I’m paraphrasing a bit): People with lower skills, knowledge, and expertise tend to overestimate themselves, while those who are more skilled, knowledgeable, etc., tend to underestimate themselves. Some of this is hypothesized to be because incompetent people may be too incompetent to recognize that they are incompetent, while competent people are competent enough to realize they may not yet know everything and still need to learn and improve.
