The official bi-annual London meetup for fans of the popular blog Astral Codex Ten (formerly Slate Star Codex) by American psychiatrist Scott Alexander. If you’re reading this, you’re invited! Please don’t feel like you “won’t be welcome” just because you’re new to the blog, demographically different from the average reader, or hate ACX and everything it stands for. You’ll be fine!

The meetup will be held at Newspeak House. There will be light refreshments and an ongoing unconference. Please please register on Eventbrite if you plan to go, because ACX has many fans in London and we need to know how many people are coming. If it is fully booked you won't be able to enter without a ticket. When registering you will have the option of making a donation, which will go towards catering and venue costs. £10 would be great.
