This is a deeper question than it sounds. The "point" of a modern IQ test is to identify cognitive deficits to target interventions. It's abused widely among non-practitioners as a ranking of intelligence, which it is not.

I think it's widely used in research as a marker of intelligence (and for good reason - correlates really well with cognitive abilities).

		I don't think we have to hash this out, because "marker of intelligence" and "ranking of intelligence" are not the same thing. A rank implies a reliable scale, which IQ doesn't provide. (It's also just fine if we disagree about this --- researchers do too!)
