Probably the same level of data behind the article we're discussing.

If she had started the article with "I'm just basing this whole article on my own biases and no real data, but..." then we wouldn't really have much to argue about.

I think in this case the article is trying to shift the burden of proof. Why should it be on someone who's asking whether it's a meritocracy rather than on the folks who're repeating this claim? And if the answer is in the affirmative, let's have that discussion.

This isn't directed at you as such. Just that a lot of folks assume the burden of proof ought to be on the questioner(s) of this proposition rather than the proponent(s).
