Welcome to The Nonlinear Library, where we use Text-to-Speech software to convert the best writing from the Rationalist and EA communities into audio. This is: Less Wrong NYC: Case Study of a Successful Rationalist Chapter, published by Cosmos on the LessWrong. It is perhaps the best-kept secret on Less Wrong that the New York City community has been meeting regularly for almost two years. For nearly a year we've been meeting weekly or more. The rest of this post is going to be a practical guide to the benefits of group rationality, but first I will do something that is still too rare on this blog: make it clear how strongly I feel about this. Before this community took off, I did not believe that life could be this much fun or that I could possibly achieve such a sustained level of happiness. Being rational in an irrational world is incredibly lonely. Every interaction reveals that our thought processes differ widely from those around us, and I had accepted that such a divide would always exist. For the first time in my life I have dozens of people with whom I can act freely and revel in the joy of rationality without any social concern - hell, it's actively rewarded! Until the NYC Less Wrong community formed, I didn't realize that I was a forager lost without a tribe... Rationalists are still human, and we still have basic human needs. lukeprog summarizes the literature on subjective well-being, and the only factors which correlate to any degree are genetics, health, work satisfaction and social life - which actually gets listed three separate times as social activity, relationship satisfaction and religiosity. Rationalists tend to be less socially adept on average, and this can make it difficult to obtain the full rewards of social interaction. However, once rationalists learn to socialize with each other, they also become increasingly social towards everyone more generally. This improves your life. A lot. We are a group of friends to enjoy life alongside, while we try miracle fruit, dance ecstatically until sunrise, actively embarrass ourselves at karaoke, get lost in the woods, and jump off waterfalls. Poker, paintball, parties, go-karts, concerts, camping... I have a community where I can live in truth and be accepted as I am, where I can give and receive feedback and get help becoming stronger. I am immensely grateful to have all of these people in my life, and I look forward to every moment I spend with them. To love and be loved is an unparalleled experience in this world, once you actually try it. So, you ask, how did all of this get started...? Genesis, or a Brief History of Nearly Everything The origin of the NYC chapter was the April 24th, 2009 meetup that Robin Hanson organized when he came to the city for a prediction markets conference. Approximately 15 people attended over the course of the night, and we all agreed that we had way too much fun together not to do this on a regular basis. I handed out my business cards to everyone there, told them to e-mail me, and I would create a mailing list. Thus Overcoming Bias NYC was born. It was clear from the very beginning that Jasen Murray was the person most interested in seeing this happen, so he became the organizer of the group for the first year of its existence. At first the times and locations were impromptu, but in August Jasen made the brilliant move of precommitting to be at a specific time and place for a minimum of two hours twice per month. Because enough of us liked Jasen and wanted to hang out with him anyway, several people began showing up every time and a regular meetup was established. Going forward we tried a combination of social meetups, focused discussions and game nights. Jasen also attempted to shift coordination from the mailing list to the Meetup group, but Meetup is not a great mailing list and people were loathe to use multiple services. That now serves as our public face. In April 2010, Jasen departed to run the Visiting Fellows progra...
