In a post last week, @ATabarrok suggests we think of misinformation as an equilibrium outcome. In Ch 8 of Hidden Games, we do. Here's a short rundown.

Warning: for the sake of brevity, I'm using econ jargon.

Lately, everyone's been asking me how to recycle correctly.

The answer is, it depends and is really, really complicated, but here are two simple rules that, while imperfect, are probably an improvement over your current habits. #1 Don't recycle:

- Anything dirty, especially if it has food waste on it
- Anything that's not 100% recyclable

Recycling these things causes recyclers to throw out entire batches of recycling. When in doubt, leave it out.

Here's what we make sure to do. Image #1: communicate the public good ("avoid spreading coronavirus; do your part to keep our community safe").

The goal is to activate people's (not-necessarily-conscious) concern for their reputation.

New newsletter discussing insights from game theory on political spin.

Summary in this thread. Based on ongoing work with @moshe_hoffman 1/12 What are common features of spin? Why are they so common?

I'll illustrate with examples from recent political "debates" on social and mainstream media. Though such spin shows up in many other contexts (e.g., dating profiles, scientific research). 2/12
