IQ is an immutable characteristic. And the behavioral disposition of an IQ bracket seems to be determined by genetics.
It seems to be all about "dick size" in today's world, not "brain size". Meritocracy is treated as a bygone of a "racist era"-- which is a ridiculous proposition because an unqualified person in a position of specialization will conclude in catastrophe.
The pyramid of IQ has seemingly been flipped over and is-somehow-balancing on it's peak, and to reach it's summit you have to climb up to it's base.
I don't know what my IQ is, nor do I care much about it. But I am not discounting it as a useful metric.
All I know for certain, is that what I don't know, far outweighs what I do know.
