Selected academic fields by estimated intelligence

I am quite skeptical about the possibility of condensing the complexity of “intelligence” down to a single number “g”, but even if this were some kind of approximate metric for actual intelligence, I do not see how this type of “research” is of any use. It only seems to promote unnecessary social abrasion by letting those who belong to the more “intelligent” fields inhale too deeply of their own success and making the others feel less. It is at best misleading and at worst borderline eugenics.

Estimated by who? By some account on Twitter.

Estimated how? By GRE SDU score for graduates. That's better than I expected, except that there is no link to the source of the data, so there's no verifiability. (Note that teqsun linked to the actual source in a top-level comment here. Also note that the actual source ranks "Classical Language" as the second-highest field, which is a rather glaring exception from the impression given by the tweet.)

One dentist makes more than 10 philosophers. Who's intelligent now?
