I was going to post this in my reply in the hidden agenda thread, but thought I'd start a new thread instead.
I've been wondering lately, although I don't have any evidence to back it up at the moment - do type weaknesses necessarily remain weaknesses in the way they're portrayed, as the individual matures? i.e. would a healthy, mature individual of a given type, especially with some life experience behind them also, have better control over their weaknesses (for lack of a better way of describing it) as compared with the same individual before they'd reached that level of maturity?
I'm specifically thinking things like the super-ego functions - although they might not become "strong" in the same way as one's ego-functions are strong, do they become less of a problem as one gets older and matures, provided one is wise enough to learn from their mistakes?
