Edit: We have tentatively decided to go to the fallback meetup topic and will meet in the courtyard as normal.

We'll be meeting to hang out and take turns singing songs. Singing is purely optional, and you don't have to be a good singer to take a turn. There will probably be at least one smartphone available for looking up lyrics.

In case of inclement weather, we plan to talk about weather forecasts and event planning - and, more generally, about making plans given uncertainty and about communicating uncertainty to decision-makers.

Upcoming meetups:

• Oct. 04: Availability Heuristic
• Oct. 11: Fun and Games
