Damn if only this article actually explained why you see this effect from random data. Unfortunately it doesn't seem like they understand the maths enough to know. Does anyone fancy reading those papers and giving us a TL;DR?
They constructed a straw man and then bitched about the straw man. In effect, they proved Dunning Kruger.
Yeah - I kept looking for the meat of the argument. The graph of random data looks a little correlated and I’d love to know why.
That being said I loved the mercury/Glasgow explanation. Anecdotally I see that all the time.
