What is a person using the IQ score for?
If the score is used as a general predictor for one's future job related financial success, they tend to be fairly accurate for IQs below 100, but not at all reliable for IQs above 100 (where 100=average).
Also for IQs below 100, they are useful in determining what kind and how much services/aid is necessary.
Used as a means of judging a person, however, they are entirely useless.
IQ test results provide narcissistic supply to some people so I guess they have some usefulness in a very limited way.
I've known several brilliant people who were too dumb to come in out of the rain.
