Mutz’s original article was called, “Status Threat, Not Economic Hardship, Explains the 2016 Presidential Vote,” and Morgan’s reply is called, “Status Threat, Material Interests, and the 2016 Presidential Vote” (it originall...

I didn’t think this still happened in 2018 . . . I opened my email to see 50 emails, from 50 different people, all with the same meaningless subject line. (In case you’re curious, it was “Re: Clerkships team.”) There was no initial email: All 50 of the messages were of the form, “Hey, this […] The post Reply-all loop appeared first on Statistical Modeling, Causa...

Mark Palko writes of the Ponzi threshold: “sometimes overhyped companies that start out with viable business plans see their valuation become so inflated that, in order to meet and sustain investor expectations, they have to come up with new and increasingly fantastic longshot schemes, anything that sounds like it might possibly pay off with lottery […] The post The Ponzi threshold and...

On Wednesday, STOC had a great complexity session and the best complexity paper of the conference, Cody Murray and Ryan Williams extending Ryan’s celebrated result separating NEXP from ACC0. Cody and Ryan show there are problems in quasipolynomial time (2poly log(n)) that do not sit in ACC0, a near exponential improvement from Ryan’s original work. The key insight shows that if NP has nk-size ...
