Apparently, the guy who invented IQ decided that your IQ is, basically, your mental age divided by your actual age, multiplied by 100.
My godfather's a shrink. He did my MBTI type and function tests, so I asked him how he'd go about estimating someone's mental age, and whether there was any particular test that was well-known or respected. In his opinion, it's linked to wisdom. He talked at length about it, so it's impossible to put everything he said here. But it was jolly interesting.
What do you think about it being linked to IQ? Do you think that raw intelligence is necessarily related to maturity and/or wisdom? (Here I'm thinking of someone I know who tests in IQ tests as a genius, but if he were a D&D character he'd have a single figure wisdom score). I find this interesting, because if the two ideas were originally supposed to be linked, then howcome IQ tests for many years haven't featured any social/emotional component? Surely that ought to be present, if we're testing something that's meant to be linked to maturity?
What do you think your closest family/friends would say about your mental age? What would you say? What sorts of things would you look at or consider, to figure it out?
Anything else you wanna add, that seems pertinent to you?
