I actually don't have any problems with Yang Hai. Although his interwebs presence is more recent, he was practicing and teaching and doing his thing for a long time before it became cool. Like everyone else, he got what he got and that's what his understanding is. What he does is not necessarily what I'm looking for, but at least he really learned from someone at some point and practices whatever that is.
It's a bit of a sidetrack, but this is a silly thread, anyways, so anything is fair game-- the Dunning Kruger effect isn't a real thing. More specifically, the method of statistical analysis they used provides the same results when applied to randomly generated sets of numbers, so their data analysis is actually kind of meaningless. Beyond that, even if the numbers were good, their analysis is kind of forced. Like, they interpreted it as "the less you know, the more you think you know", but the exact same data could have been interpreted as "people like to think of themselves as 'normal'". So, as I like to say, people who believe in the Dunning-Kruger Effect are the best examples of it.
