Have you read the thing? The author implies that the Symbol Digits Modalities Test measures cognitive ability, similarly to an IQ test, when in reality it's intended only to screen for impairment. They also call a Pearson correlation coefficient of 0.2 "strong".

Even the title is full of spin. The paper claims to unearth the "root" cause, when the whole thing is just predicated on the assertion that correlation = causation.

Would it surprise anyone to know that the author (pic related) is a social scientist?
