false symmetry

At an Overcoming Bias meetup group I went to a couple weeks ago, several people claimed that learning how to think rationally has helped them get ahead in life. My instinct is that this is probably true, but it doesn’t seem to me that rationality enthusiasts are statistically better off than irrational folk.

Of course, I’m personally interested in understanding how I can use rational thinking to get ahead, in personal and professional life, but I haven’t seemed to be able to inductively reason how I might go about this. Any ideas?
