Response bias or "response style" is the keyword for phenomena like these. "Extreme responding" or "extreme response style" are terms for gravitating away from the neutral option.
I don't know if there's research on whether this is correlated with overconfidence.
Thanks for the link! I was aware that this style exists, but the correlates are interesting. Seems that the "extreme/mild" style is correlated with:
The intelligence/education link seems obvious in hindsight, but that is an illusion because if someone told me the opposite conclusion, I would have a good "explanation" for that, too.
There is probably some relation to...
Epistemic Status: I am very uncertain about this topic, but think that, if anything, I may simply be mislabeling or misunderstanding some real signal.
I imagine that there may be aspects of a person's particular tendencies in judgmental forecasting that reveal something about their personality, such as their OCEAN (Big Five) measures or their Moral Foundations.
The following sequence of thoughts - "My life experiences indicate that I may be more conscientious than my OCEAN results suggest", "I remember selecting neutral for many answers that were likely related to conscientiousness", "One reason for why I selected neutral so often might be that I am underconfident about aspects of my personality, provided I have a track record of being underconfident, especially in judgmental forecasting" - led me to the question:
Could measures of overconfidence or underconfidence in judgmental forecasting be used to control for the effects of psychological survey participants gravitating away from or towards, respectively, the "neutral" option in surveys?
Relatedly, one might ask "Is over- or under- selecting the neutral option in psychological surveys an actual phenomenon?", "What occurs when there is no neutral option on a psychological survey versus when there is?", "How does under- or over- confidence in judgmental forecasting relate to under- or over- confidence in other facets of people's lives?
More generally, I suppose this intrigue might fall into the wider category of "reflections of cognitive biases or personality present in people's forecasts and forecasting tendencies". I would be content if people shared with me their thoughts on my above questions, or if people shared any resources they think would point me in a good learning direction (e.g., recommend I look into some line of research or work adjacent to these ideas). Thank you.
