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.)

Data-based but in a relaxed, imaginative way that suits the goal. Management consulting ftw!https://twitter.com/PeteButtigieg/status/1224564353040625665 …

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

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): https://statmodeling.stat.columbia.edu/2020/02/01/forget-about-multiple-testing-corrections-actually-forget-about-hypothesis-testing-entirely/ … My attitude (new box in 2nd ed of my book):pic.twitter.com/TiP4n0TapN
