Similar to personality typing, do you know (or care) what your alleged 'IQ' is?

I've never had mine tested, nor been interested in having it tested.

I know a subset of people crave to know it for themselves and about others, just like how people to crave to know their own personality type and that of others.

I don't even know how IQ is characterised other than being some sort of a number metric that allegedly has some kind of meaning.
