I think its a little more complicated than that.
When it comes to shooting guys tend to (and no, not all guys):
1. Have bad habits from doing it before
2. Already know because just like anything else that a "real man" should know - they know
3. Try to run before they can walk - skip the basics and go straight to what they want to do
I can say that of the people I teach, the females tend to make more progress.
