It has its place if the scope is correct. In the case of IQ, like BMI, the scope is for an average over a population. The objections are only really valid for an individual because any one person can override the entire point of an IQ test. Taken over the course of hundreds, if not thousands of people, and split by various demographics, they can give you meaningful information because those little bumps that are so objectionable in an individual case are ironed out.

Consider the analogy of anecdotal evidence. A single anecdote is meaningless, as is applying an IQ test to one person. Build them up in a controlled manner, however, and you have something you can use.
