It's hard to know what you don't know. Let's say, objectively you know 10 of 100 "facts" of Discipline X. But given you're a novice you believe the universe of X is say only 50 "facts." Naturally, from where you stand your 10 now doubled in value. So I would think the problem isn't the overestimation or overvalue per se. 10 is still 10. It's that you've underestimated the size of the X universe thus making your perception of the piece of pie feel bigger than it really is.
If that makes sense.
The key is to be aware that there are things you don't yet know, and not let your ignorance get the best of you.
