Roughly, there's two populations - those who apply what they learned in magic (microeconomics, essentially) to life and those that don't. The latter tend to spend way to much time on card games. The former start saying things like "this event is pretty low EV for me, i think I better study/write that paper/work on that project/etc. instead."

In any case, as people get better at Magic, they get better at thinking about the consequences of their actions within the game. This seems like a natural stepping stone to thinking about consequences in all situations, though the trick is getting people to generalize it.
