What if something works even if the arguments are unscientific? Example: How to get an apple from high up in the tree where I can't reach? My theory is that if I knock them with a baseball bat they fall because they are afraid of baseball bats and don't want to be hit. I have tested it and it works. A physics teacher I know disagrees, and a biologist disagrees.

What if psychology has such things that just work even if the theory is wrong? The trauma healing layman psychology industry might have a method that works for some people, so that they get into a better mental state.
