"they have not yet learned to shoot", very true but not through a fault of their own.

Shotgun shooting instruction lags behind other sport teaching. The approach that is the most frequently applied is to teach the basics of safety, get the pupil on the stand and let him have a go at full speed clays. The cycling equivalent would be to put someone on a racing bike and let him have his first try in traffic.

If instructors approached shooting in the way that cycling is taught to adult non cyclists, ie start with a balance bike, which lets the pupil discover equilibrium, then move on to slow riding pedal bikes, etc, in other words a layered gradual teaching method, then we would see positive results.

I am convinced that instruction deficiency is partly responsible for the failure to attract new shooters.
