Before controlling for different factors, the article compares people with IQs of 100 with people with IQs of 120 or 130, and finds a pretty big difference. Then, after the controlling, it compares people with IQs of 105 with people with IQs of 110 and draws a conclusion. Seems like a cheat to me.

The article doesn't cite the original, so I'll have to search for it.

ETA: true, you don't need an IQ of 130 to become a dermatologist, but that doesn't mean you'll get there with an IQ OF 98, either. Doctors' IQs, as a group, are higher than average (google it).
