I can totally accept the paper being wrong, but yeah this is how I feel. Fine to reject the claim, but if it's the word of a random commenter saying "trust me bro" vs that of researchers who published in nature and put all their evidence out there for everyone to see... I'm going with the latter (I'd even go with that were it not published).

Like at least make some critique about the study instead of: claims bullshit, refuses to elaborate, leaves.
