What interested me was how much the study of drawing was relevant to rationality. Not only do you have to learn to observe reality (this is surprisingly hard), but you have to pretty much scrap your entire model of how you think drawing works. (Almost everything you will naturally gravitate towards is wrong). Most artists don't notice that they should be applying these lessons to the rest of their life, but I think the skills can generalize if attention is brought to that notion.

It seems to me that everything about drawing that makes it a good training ground for rationality is even more true of, say, long range precision rifle shooting. Also, evaluating your progress is easier because the metrics are more objective (targets don't lie) and your biases are more apparent (you can go so far as quantifying your biases by fractions of a centimeter and even giving them directionality in 3-dimensional space).

"Hey, can I shoot you?" is somewhat less appropriate as a conversational gambit, compared to "Can I draw you".

Your response misses the point. Obviously, I didn't have marksmanship in mind for helping you approach people on the subway. I believe the primary goal of this sequence was to explore how to improve general rationality through drawing, not merely better social skills through drawing. It is my contention that various shooting sports teach skills that are just as or more readily transferable to other domains that require rationality. Of course, I am willing to be corrected by Raemon as to his/her intention in writing this sequence.
