I didn't see anything in the study (that I also skimmed tbh) that is clearly wrong, which makes me dismiss the results. It's just because I don't think this is evidence enough to change my priors. i.e. My gut tells me this is wrong and I don't buy it. The sample is 267 people, tiny enough that I'd expect an analysis to be done with a linear model with few features. They used 14 features, but had a pipeline to select "model (out of 3), feature set, and threshold for prediction". There's _so_ many degrees of freedom there that _by default_ I assume there's leakage. I'd love to see this paper replicated! It would be amazing if this were true. But if I had to bet on this, I wouldn't give more than 20% chance of being true.
