Find us on level 2. For this month bring along a suggestion of a book you want more people to read. Come along to our regular monthly pub meetup to talk all things math, science, technology, engineering, thinking, growth, reasoning and beliefs. If you are an aspiring rationalist, a nerd, geek, scientist or just a quiet thinker - we can't wait to meet you to share ideas, discuss, debate, learn and grow together. If you are interested in our rationality dojos, ask us about them in person. See you there! Also, while you are at it - bring a friend along too! We usually get ~15 attendees through various advertising avenues.

WHEN: 20 August 2017 03:30:00PM (+1000)

WHERE: Henley Club, Melbourne

Melbourne rationality dojo, 20 August at the Henley Club in central CBD, Melbourne.


Reacting to evidence and surprises.. Drawing on psychology research, and practical application inspired by the CFAR workshops, we discuss how to improve the accuracy of pour view of the world and create habits to achieve our goals.

This will be a lightly facilitated group discussion, so wear your thinking caps. As always, we may draw on the content in the Less Wrong Sequences and top books in relevant fields. If you'd like to think ahead - and sound smarter ;-) - see section 1 of http://www.rationality.org/resources/rationality-checklist


  • An inquiring mind, and observations you may have on the topic.
  • Perhaps a snack or drink to share. (Bonus points for healthy choices.)
  • Interested friends.


3:30pm to 6:30pm (and then optional dinner). Come early to catch up, and the meeting proper begins at 4pm sharp.

At about 6:30pm some of us generally head for dinner nearby, and you are welcome to join us.


The Henley Club Level 1, 8 Rankins Lane, Melbourne CBD https://goo.gl/maps/vmFL6JeKQSD2

It's down a lane (off Little Bourke, near Elizabeth) and one flight up a stairwell. If you have trouble, text or call Adam on 0412 064 542.


The Less Wrong Melbourne Rationality Dojos are a chance to polish your planning, motivational, critical thinking and other rationality skills. We welcome new members who are interested in exploring rationality. We're "aspiring rationalists" and always open to learn.

WHEN: 14 August 2017 06:15:00PM (-0700)

WHERE: 1769 15th St, San Francisco, CA 94103-3333, United States

We’ll be meeting to give and listen to very short talks!

We’ll do 7-minute lightning talks with 3 additional minutes allowed for questions. We’ll also limit the number of programming-related talks to no more than half of all talks, in order to promote variety.

A talk doesn’t have to be formal, planned, or even something that you’d expect someone to Give A Talk About; it can be as simple as telling the group about something you find interesting or cool. In the past, we’ve had people talk about topics like: how complicated the process of organizing fresh food for airplane flights is, their experience volunteering for a local political campaign, a video game they were designing and writing, and many others.

We don't expect any sort of preparation or practice for these kinds of talks. They're very casual and the expectations are low. If your talk isn't great, it's okay because we'll just move on to another one in a few minutes. If it helps, think of it this way: you're just being given the conversational floor for a few minutes, in a slightly more organized way than usual.

For help getting into the building, please call (or text, with a likely-somewhat-slower response rate): 301-458-0764.


We meet and start hanging out at 6:15, but don’t officially start doing the meetup topic until 6:45-7 to accommodate stragglers. Usually there is a food order that goes out before we start the meetup topic.

About these meetups:

The mission of the SF LessWrong meetup is to provide a fun, low-key social space with some structured interaction, where new and non-new community members can mingle and have interesting conversations. Everyone is welcome.

We explicitly encourage people to split off from the main conversation or diverge from the topic if that would be more fun for them (moving side conversations into a separate part of the space if appropriate). Meetup topics are here as a tool to facilitate fun interaction, and we certainly don’t want them to inhibit it.

We will be meeting at the residence of one of the meetup regulars to talk about cooking, and also cook (and then eat). There may also be some knife sharpening at the beginning of the meetup.

  1. Pasta buffet
  2. Taco salad buffet
  3. Asian cooking (rice, stir-fry, chickpea patties)
  4. Other

...and tells us the menu will be chosen based on votes and volunteers to bring ingredients for and/or things that complement a menu option.


Take the metro to the Prince Georges Plaza metro stop, or park in the metro garage there.

As you come up the metro escalators, you will be facing a traffic circle, and Belcrest Road. Go around the circle, continue, and take a right on the next street (Belcrest Road); the building entrance will be on your right. Call or email Richard Bruns ([firstname][lastname] at gmail) so he can let you in or send someone to do so, or tailgate behind someone else.

WHEN: 10 August 2017 07:00:00AM (-0400)

WHERE: 2920 Ch de la Tour, Montréal, QC

Meetup Event: https://goo.gl/XRHGS6

Location: room 3195, Pavillon André-Aisenstadt, Université de Montréal

Being able to correct the behavior of an AGI will be the discussion of our next AI Safety meeting. Basically we want to know if we can design a utility function that accepts human intervention (even though it might interfere with its other goals). More specifically, we will discuss the 3 papers below. All results are by necessity about simple toy models. They are meant to direct future research.

Here's a short description of each paper. I recommend you read as much as you can in this order.

Corrigibility (https://intelligence.org/files/Corrigibility.pdf): This sets up the problem and discusses issues with the most obvious approaches.

The Off-Switch Game (https://people.eecs.berkeley.edu/~dhm/papers/off_switch_AAAI_ws.pdf): If the AI is uncertain about the users utility function and treats any action by the user as information about this utility (as in the case of inverse reinforcement learning), then the AI may be amenable to correction. A more exact statement (with caveats) is found in this paper.

Safely Interruptible Agents (http://intelligence.org/files/Interruptibility.pdf): Similar to the previous paper but with a different approach and focus. They ask whether it's possible to interrupt an AI without damaging it's learning (i.e. will it learn as if it never gets interrupted). As above they show this is possible in the case of an uncertain AI. They even manage to show an example of an ideal 'perfect' intelligence for which this is true.
