And if you have too many free parameters, you get overfitting.

OK, but that sounds like a bit of a hybrid to me. You're talking about
generalisation *and* analysis. I was referring to generalisation purely as a way
of classifying roughly, with some acceptable error, e.g. "apples are edible". In
addition, I'm assuming that the generalisation is at a subconscious level, or a
mechanism that the mind employs more or less implicitly. Your generalisation
methods sound more conscious and explicit.
