I was pretty much always this way, except way more overconfident in conclusions and underconfident in myself. It took failing a lot and succeeding in bigger things to cure both of those even part-way. I got a big dose of Outside View when I hit college.

Of course, I didn't come pre-loaded with the formalism, but a lot of the time (definitely NOT all the time!) when I encountered the formalism it was 'okay, now I've seen that written out'.

Spock was an influence, but may have been more of a 'you too'.
