Maladaptive learning, being bullied into certain behaviors makes you worse at others.

You learn a task like washing dishes but also a behavior like focusing only on outward appearance or letting other considerations go to the wayside to complete visually obvious tasks - the result may be using short cuts like improper cleaning methods which result in sickness (cleaning only the visible dirt) but also could lead to a culture of hiding faults (why do our guns look so clean but misfire so often, why are these reports filled in neatly and completely but ikey information is often wrong or fabricated)

The army and others try moving away from it but of course it's hard getting the changes through to people because when the army experts say 'stop hazing it's making us worse' everyone that was hazed says 'I was hazed and I'm the best possible version of myself!!!' or 'This is just liberal nonsense making us weak!'
