And its effective. When working with kids years ago in athletics, I encountered an 11-year-old boy who was under the assumption that the womens mile record should be faster than the mens. If people are raised with a grasp of reality like that, how can they possibly figure out what social codes, policies or politicians to support?
I remember in my youth when I got into some competitive sports, I was surprised to find such a gap in mens and womens track event times.
It had always been my experience that the girls ran much faster than me. Especially after the first 60 yards or so.
