Good thoughts! I think there is much more nuance as I disagree with some of your points:
> I believe that impostor syndrome is a lack of overconfidence in one's abilities - that implies that you have the the ability to assess competence --
I think that competence in an ability is not perfectly synchronized with ability-assessment-competence.
I think ability-assessment-incompetence can result in both under- and overconfidence, before accounting for a self-esteem bias. Being underconfident is also an incorrect self-assessment, which doesn't imply ability-assessment-competence.
> If you lacked the ability to assess competence in yourself, then you likely would not have impostor syndrome.
Here I disagree the most. I think impostor syndrome can be the result of ability-assessment-incompetence, somewhat detached from their true competence in the actual abilities involved.
