School Corporal Punishment is purported to serve seven main purposes.
The first purpose, and arguably the most important, is that it is meant to deter.
It is very difficult for ethical and practical reasons to study SCP scientifically but we can consider whether pain deters other activities, such as cycling.
The maximum penalty or cycling is quadriplegia for life.
Lesser penalties include slow death by mutilation and severe “road rash” and broken bones. Minor punishments include saddle soreness, excess fatigue, bruises and grazes.
Despite these very harsh penalties cyclists persist in cycling. We must conclude that neither death nor pain are effective deterrents.
No wonder the paddle, slipper, strap and cane all failed at school.
