It's fairly trivial, but related to Simpson's paradox, which isn't. There is a hidden assumption that's worth pointing out.

It was probably posted due to recent discussion of casual inference. Judea Pearl talks about it in The Book of Why.

you mean causal? though I'm intrigued about casual inference now that you mention it. would this be a branch of behavioral economics where actors investing only a little effort come to a different conclusion than those looking at it formally? Could this explain the wealth gap?

Yes, causal. :)
