It takes one bad apple to ruin it for the bunch, as they say.
That said, I lived and worked for a few years in a country where IQ tests were the norm for hiring people. When hiring for my own team (C++ devs), I did not use them as I found they were a very poor filter with both high false positives and high false negatives in terms of indicating whether or not you should hire a particular person.
