They're judging intelligence off of IQ?

That's terrible. IQ is only a measure of 'school learning,' which women have historically been dissuaded from. Although this has largely changed, I would still question the validity of basing anything on IQ that IQ was not meant to measure...such as varying intelligences between sexes.
And yes, they DO need to say what they mean by intelligence. Because, frankly, there are a myriad models of what intelligence and learning means. Right brain, left brain, multiple intelligences, tabula rasa, and all the rest.
This is particularly sad after having studied a bit about the process of learning for my museum classes.
