    I'm teaching a graduate class called "Network Epistemology" this semester. As an experiment, I'm going to do a twitter thread each week about what we're reading and some general reactions to it. (In order to remain on-brand, I'm already two weeks late with the first one.)

    Is there a good reference for empirical work on whether paying government officials higher salaries reduces corruption?

    are your rigidities nominal or real? when someone says "Phillips curve" how do you feel? does your model prove, with rigorous notation that recessions are people taking a vacation?

    PS/ Unfortunately he eventually says some silly things that betray some misunderstandings of game theory, proving that economists retain an edge in some ways even on remarkably clever people!

    that the important relations between individual nodes are binary ones, or ones that can be built up out of binary relations. (So an edge can represent affection, but not jealousy—at least not so easily.)" 2/2

    These companies rely, of course, on the Internet, which has made itself an essential part of daily life throughout the civilized world. Even humble and sometimes ancient pieces of infrastructure like telephones, electrical power and roads are naturally called networks now 3/4

    I was explaining Twitter to a senior colleague and how it differed from just any old text and images over the Internet and remembered this old piece of Internet wisdom about generative constraints. There are probably other good constraints we haven't thought of yet. 2/2

    Constraints in platforms add a lot of value. On Twitter things have to be short. On Wikipedia they have to be factual. On Instagram they have to be visual. 1/2

    One of the nice things about Andrew Gelman's blog is how benign posts routinely produce deep debates about foundations of statistics. This time, the concept of "calibration" (see comments): My attitude (new box in 2nd ed of my book):
