Mounk didn't read the hoaxers writeup carefully enough to be a reliable judge; he gleefully tweeted two papers from the hoax that were rejected everywhere they were submitted, as evidence of the important problem the hoax uncovered --- this despite the fact that the hoaxers did in fact provide an accounting of what got accepted where (even though their writeup at the beginning of the piece misrepresented that accounting).

From what Pinker wrote, who knows if he even read it?
