I'm not an academic, so I'm curious, are papers like this just for fun or are they intended to actually contribute to our understanding of the world? Because I can't help but think that the methodology in the paper is dubious. Do we just the guy because he is a professor? I suppose ideally the reputation system is such that if it is revealed someone is just making things up they'll get booted out.
Not trying to hate on it, it was just an odd paper so it had me wondering.
