I'm all in when it comes to call bullshit on something. But because we (hackers) are used to boolean decisions, we are looking for counter-examples.
But these are just non-arguments when the finding is "In 9 out of 10 cases, ...". The anecdote is the 1 out of 10 case.
Let's try to question anything, and when it is suspicious - by all means, say so! But, I guess what the author is trying to say (beyond the whole Downvote discussion) is that we should try to reason and make a proper argument. Especially one that is not already addressed in the research.
