I can't find much about prediction markets on SlatStarCodex except a 2016 review of Superforecasters which takes the view that :

Maybe all this stuff about probability calibration, inside vs. outside view, willingness to change your mind, and fighting cognitive biases is starting to sound familiar?

So maybe it was Hanson > Yud > Rationalist / EA culture, but Hanson likes to take credit for ideas much older than him. And we know the Rats rely on pop science and podcasts much more than research literature.

The futarchy paper is funny because Hanson had the idea in 2000 but took 13 years to publish it. That is a good sign that he kept getting a desk reject or "revise and resubmit." But were people reading his blog, a mix of Libertarian fringe writing, or specifically something by Yudkowsky or SlateScott?
