I noticed the use of the word „unlearn“, for overcoming behavior you got used to, but which isn’t exactly helpful or productive.
So you learned something wrong, then you un-learn it, and then you learn something else.
Of course, this doesn’t work in any way. First, you’ll hardly forget what you learned and thought was smart to do. Second, if you really un-learned something, you could again learn the behavior you wanted to stripe off, since you’d have forgotten it. Third, in fact „un-learning“ simply means learning, how to do things better, and changing your behavior. Only if you had internalized some behavior so it had become kind of unconscious, I could imagine that un-learning would be the correct term.
But in most cases, the word is just being used to make common learning processes sound more substantial and somehow special.
