IQ of someone is not stable: it changes depending on how much you train to do it or the mental/psychological state you are in when you pass it. Thus it is not a sound scale to measure anything.
The fact that it is merely a ranking of people further push it in the realm of straight bullshit.

How can you possibly measure intelligence separately from the mental state of the person taking the test
