Now there is no necessary connection between rationality and a sci-tech association, and the correlation in the world probably isn't that strong, but I'll believe most readers here are strongly sci-tech. And this post is surely right that as a man you'll get far more mileage out of the social status that goes with sci-tech, at least in many female eyes, than you will from your rationality. Rationality, after all, has pretty much zero, if not negative, social status in our society.
