Alex Flint and I are doing a series of seminar/discussion events in Oxford, to which anyone from LW would be very welcome. Especially as the theme is Rationality & AI Risks!
They're being held at 5pm on Saturday in Exeter College, and will go on throughout November. We had over 10 people last Saturday discussing Heuristics and Biases, and plan to go onto Bayesianism this week. They'll probably last for about an hour, though we may decamp to the pub afterwards to continue discussion.
If you're in the area, you might also be interested in the other events run by the Oxford Transhumanist Society.
