Good observation. I used to work in finance and noticed this, too. Whenever explaining anything from the area of economics, the last people to grasp the concept were people who studied economics - because they have had their heads filled with a lot of bullshit concepts during their edumakation, preventing them to see things for what they were, because there were just too many (mostly bogus) concepts getting in their way.

To be fair they were followed by people like lawyers and psychologists, who thought they understand and know everything and were mostly a pain in the ass to deal with.

I had the easiest time with people unsullied by "higher education" or people from computer science or engineering backgrounds.

Actually it's quite fun to watch. Even highly intelligent and knowledgeable gold bugs and Austrian economists are taking their time in understanding Bitcoin and are only slowly, one by one coming around. And that's the worthwhile minority of economists. The guys who swallowed all of that Keynesian stuff? I gather they'll be among the "laggards" which adopt BTC, together with my grandmother and my autistic nephew.
