Scott Alexander announces that the adversarial collaboration contest will proceed, lists the registered teams, and introduces a new rule for proposing topics. Longer summary

Scott Alexander provides an update on the adversarial collaboration contest he previously announced. He lists seven teams that have registered so far, covering topics such as circumcision, incarceration, the simulation argument, abortion, critical learning periods, and eating meat. With more than five teams registered, Scott confirms that the contest will officially take place. He invites others to form teams in the comment section, with the caveat that only people with usernames A-M can propose topics, while those with names N-Z must accept existing proposals. This rule is an experiment to address the issue of participants preferring to propose their own topics rather than accepting others'. Shorter summary
