And there's also no discernible difference between seeing a psychotherapist and spending the same amount of time talking to a randomly selected college professor from another field. It's just talking to anyone that helps you get better, apparently.

Unless this has been tested for random people other than just college professors, there's a stronger case for saying that talking to a person of a certain intelligence and education level helps you get better. And I suspect that it doesn't generalise to "talking to anyone that helps you get better" but I haven't looked into it.

(I'm sure there are other factors, but I'm just going by what was said about college professors.)
