I loved Mr Shiner's list - cracked me up
I think reasons include not just attention to detail and anticipating problems and their solutions, but an attitude. Women are generally more able to say "sorry, my mistake, won't happen again" (esp when it's NOT my fault) and take responsibilty in that way, understanding that during reh/tech there sometimes needs to be a scapegoat as much as a pin, and we just let stuff roll and keep moving.
I've always been taught a great attitude for SMs is a cross between benevolent dictator and mom. Makes sense to me...(and Radar is a great analogy - we have to know everything before it happens, anticipate the problems, and take the flack when someone else drops the ball.)
