I think along these lines every time someone mentions the Dunning-Kruger effect, which is frequent these days on Hacker News. It reminds me of a funny aphorism I once heard about higher education:
First you get your Bachelor's Degree, and you think you know everything. Then you get your Master's Degree, and you realize you don't know anything. Finally, you get your Doctorate, and you realize that nobody knows anything.
Finding those patterns between disciplines is always a delight--there is a surprising amount of crossover between many fields of study and human behavior. Programming was where I first found that humility is very positively correlated with competence, and the same principle shows up in a lot of other places.
Slightly offtopic, but one of the things I love about software is that it's trained me to recognize patterns in everything. Abstract thinking is really useful.
And I've recognized the same tendency you mention in myself, and across a few different topics.
It makes me wonder when I wholeheartedly agree or disagree with something... maybe I'm just still on that journey.
