Meetups Everywhere 2021: Times And Places
August 23, 2021 · Original source
Extra Info For Meetup Organizers: 1. If you’re the host, bring a sign that says “ACX MEETUP” and prop it up somewhere (or otherwise be identifiable). 2. Bring blank labels and pens for nametags. 3. Pass around a sign-up sheet where everyone gives their name and email address, so you can start a mailing list to make organizing future meetups easier. 4. If it’s the first meetup, people are probably just going to want to talk, and if you try to organize some kind of “fun” “event” it’ll probably just be annoying. 5. It’s easier to schedule a followup meetup while you’re having the first, compared to trying to do it later on by email. 6. In case people want to get to know each other better outside the meetup, you might want to mention reciprocity.io, the rationalist friend-finder/dating site. 7. To enable the RSVP system and send you email notifications for new RSVPs to your event, the LessWrong team created events and accounts for all the meetup organizers. You can claim your event and account by sending a message via the Intercom support chat in the bottom right corner of LessWrong, or by resetting your password with the email that you provided in the meetup organizer form.

Spring Meetups Everywhere 2023
April 10, 2023 · Original source
Many cities have regular Astral Codex Ten meetup groups. Twice a year, I try to advertise their upcoming meetups and make a bigger deal of it than usual so that irregular attendees can attend. This is one of those times.
Extra Info For Meetup Organizers: 1. If you’re the host, bring a sign that says “ACX MEETUP” and prop it up somewhere (or otherwise be identifiable). 2. Bring blank labels and pens for nametags. 3. Have people type their name and email address in a spreadsheet or in a Google Form (accessed via a bit.ly link or QR code), so you can start a mailing list to make organizing future meetups easier. 4. If it’s the first meetup, people are probably just going to want to talk, and if you try to organize some kind of “fun” “event” it’ll probably just be annoying. 5. It’s easier to schedule a followup meetup while you’re having the first, compared to trying to do it later on by email. 6. In case people want to get to know each other better outside the meetup, you might want to mention reciprocity.io, the rationalist friend-finder/dating site. 7. If you didn’t make a LessWrong event for your meetup, the LessWrong team did it for you using the email address you gave here. To claim your event, log into LW (or create an account) using that email address, or message the LW team on Intercom (chat button in the bottom right corner of lesswrong.com).

23: Room Temperature Superforecaster
August 01, 2023 · Original source
Sinclair Chen. Sinclair works at Manifold; she can be spotted at most Bay Area ACX meetups. I didn’t realize the degree to which she goes hard: “CFTC, if you are reading this, know that there is blood on your hands.” This is not exactly the message I would have written. But I think, as the Catholics like to say, that it comes from a vice which is the excess or perversion of a divine virtue, and I appreciate her for being the sort of person who’s like this, sort of.

3: At an ACX meetup, I was asked why journalists don’t cite prediction markets more often, ie “The new paper says there is a room temperature superconductor, but experts are skeptical, and the forecasting engine Metaculus says there is only a 10% chance it will replicate”. I didn’t have a good answer; do any journalists have an opinion on this?

Spring Meetups Everywhere 2025 - Call For Organizers
March 05, 2025 · Original source
There are ACX meetup groups all over the world. Lots of people are vaguely interested, but don't try them out until I make a big deal about it on the blog. Some people who try meetups out realize they love ACX meetups and start going regularly. Since learning that, I've tried to make a big deal about it on the blog twice annually, and it's that time of year again.
Organizing an ACX Everywhere meetup can be easy. Pick a time and a place (parks work well if you think there will be a lot of people, cafes or apartments work fine for fewer) and show up with a sign saying “ACX Meetup.” You don’t need to have discussion plans or a group activity. If you want to make the experience better for people, you can bring nice things like nametags, food and drinks, or games. Meetups Czar Skyler can reimburse you for the nametags, food, drinks, and other things like that.
Yes. If you run an existing ACX meetup group, just choose one of your meetings which you'd like me to advertise on my blog as the official meetup for your city, and be prepared to have a larger-than-normal attendance who might want to do generic-new-people things that day.

Fall Meetups Everywhere - Call for Organizers
August 06, 2025 · Original source
There are ACX meetup groups all over the world. Lots of people are vaguely interested, but don't try going to a meetup until I make a big deal about it on the blog. Since learning that, I've tried to make a big deal about it on the blog twice annually, and it's that time of year again.
People enjoy each other’s company and keep having meetups throughout the year. The form will ask you to pick a location, time, and date, and to provide an email address where people can reach you for questions. It will also ask a few short questions about how excited you are to run the meetup to help pick between multiple organizers in the same city. One meetup per city will be advertised on the blog, and people can email you if they have questions. Organizing an ACX Everywhere meetup can be easy. Pick a time and a place (parks work well if you think there will be a lot of people, cafes or apartments work fine for fewer) and show up with a sign saying “ACX Meetup.” You don’t need to have discussion plans or a group activity. If you want to make the experience better for people, you can bring nice things like nametags/markers, food/drinks, or games. Meetups Czar Skyler can reimburse you for the nametags, markers, food, and drinks. If you feel more ambitious, collect people’s names and emails if they’re interested in future meetups. You could do this with a pen and paper, or if you’re concerned about reading people’s handwriting you could use a QR code/bitly link to a Google Form. Here’s a short FAQ for potential meetup organizers: 1. How do I know if I would be a good meetup organizer? If you can put a name/time/date in a box on Google Forms and show up there, you have the minimum skill necessary to be a meetup organizer for your city, and I recommend you sign up. Don't worry, you signing up won't randomly take the job away from someone else. The form will ask people how excited/qualified they are about being an organizer, and if there are many options, I'll choose whoever I think is best. (Or whoever Meetup Czar Skyler thinks is best.) But a lot of cities might not have an excited/qualified person, in which case I would rather the unexcited/unqualified people sign up, than have nobody available at all. This spreadsheet shows the cities where someone has filled out the form, updated manually after a basic check. Lots of cities have existing meetup groups and we’ll probably prioritize them, but we always appreciate more options. Sometimes people assume their city is big enough that someone else will do it, nobody signs up before the announcement, and then afterwards people say they wish there was a meetup in their city. Beware the Bystander Effect! If you are the leader of your city’s existing meetup group, please fill in the form anyway and say so. 2. How will people hear about the meetup? You give me the information, and on August 24 (or so), I’ll post it on ACX. An event will also be created on LessWrong’s Community page. 3. When should I plan the meetup for? Since I’ll post the list of meetup times and dates around August 24, please choose sometime after that. Any day September 1st through October 31st is okay. I recommend a weekend, since it's when most people are available. You’ll probably get more attendance if you schedule for at least one week out, but not so far out that people will forget - so mid September or early October would be best. Check your local calendar for holidays where people might be busy: If you're in the US, that probably means avoid Labor Day and Halloween. 4. How many people should I expect? Last spring, meetups ranged from one person (just the organizer) to around two hundred. Meetups in big US cities (especially ones with universities or tech hubs) had the most people; meetups in non-English-speaking countries had the fewest. You can see a list of every city and how many people most of them got last time here. (If it’s blank, it means either no ACX Everywhere was run or we didn’t get a count of attendees in the post-event survey.`) Plan accordingly. 5. Where should I hold the meetup? A good venue should be easy for people to get to, not too loud, and have basic things like places to sit, access to toilets, and the option of acquiring food and water. City parks and mall common areas work well. If you want to hold the meetup at your house, remember that this will involve me posting your address on the Internet. 6. What should I do at the meetup? Mostly people just show up and talk. If you’re worried about this not going well, here are some things that can help: Have people indicate topics they’re interested in by writing something on their nametag

There's also a moderately-active Discord that you can join at https://discord.gg/vec [remove this bit] W7TfsPg , where I make the announcements as well. Notes: Guest parking should be along the road leading in (Black Birch Trail), parking to the right as you drive in. There is an Event Parking sign but it is not the most visible. There are disabled spaces directly in front of the Common House (100 Black Birch Trail). If we overflow the road, people can use the resident lots to the left and right.

Spring Meetups Everywhere 2026 - Call For Organizers
March 13, 2026 · Original source
There are ACX meetup groups all over the world. Lots of people are vaguely interested, but don’t try them out until I make a big deal about it on the blog. Some people who try meetups out realize they love ACX meetups and start going regularly. Since learning that, I’ve tried to make a big deal about it on the blog twice annually, and it’s that time of year again.
Organizing an ACX Everywhere meetup can be easy. Pick a time and a place (parks work well if you think there will be a lot of people, cafes or apartments work fine for fewer) and show up with a sign saying “ACX Meetup.” You don’t need to have discussion plans or a group activity. If you want to make the experience better for people, you can bring nice things like nametags, food and drinks, or games. Meetups Czar Skyler can reimburse you for the nametags, food, drinks, and other things like that, though reimbursements are likely going to go out slower than last year.
Yes. If you run an existing ACX meetup group, just choose one of your meetings which you’d like me to advertise on my blog as the official meetup for your city, and be prepared to have a larger-than-normal attendance who might want to do generic-new-people things that day.
Meetups Everywhere Spring 2026: Times & Places

Many cities have regular Astral Codex Ten meetup groups. Twice a year, I try to advertise their upcoming meetups and make a bigger deal of it than usual so that irregular attendees can attend and new readers can hear about the meetups. This is one of those times.
Contact: Tess Contact Info: rational[.]ottawa[@]gmail[.]com Time: Friday, May 22nd, 6:00 PM Location: The 2026 Spring ACX Meetups Everywhere in Ottawa will be on Friday, May 22nd, at 6pm! Location: The rooftop patio of the National Art Centre (NAC), 1 Elgin St. The patio can be accessed from the street via exterior stairs (which I will label with a yellow sign reading “ACX”), or by going through the NAC to the upper levels with exits to the rooftop patio. If there is any difficulty finding the meetup, go to the Equator Coffee just inside the entrance to the NAC, contact Tess, and someone will be down to collect you. If it rains on the 22nd, we will reconvene inside the NAC atrium (ground floor area with the colourful couches). Coordinates: https://plus.codes/87Q6C8F4+CH Group Link: https://www.lesswrong.com/groups/PB4YL2K54CzmQDtC4 (Attend a meetup for a link to our discord, where all the active online conversation takes place) Notes: Come on out to encounter ACX readers, and to find out what our Rational Ottawa weekly meetup group is like/is all about! Past years have seen attendance range from 1-2 dozen at these events, and I would expect that to continue. Please feel welcome to join us even if you’re not quite sure you fit the crowd, or feel awkward about doing meetups! Food to be provided at the event!
