Mottizens sometimes use terms with obscure origins that can be confusing to newcomers. This is an attempt to provide a brief explanation of what these terms mean and where they came from to help anyone new to the community.
50 Stalins: A style of commentary which pretends to criticize something while actually praising it, e.g. “critiquing” Stalinist Russia by suggesting that it is not Stalinist enough and it should have even more Stalins. The term was coined by Scott Alexander in Reactionary Philosophy in an Enormous, Planet-sized Nutshell (2013).
Chinese Robber Fallacy: A dishonest argument that uses a generic problem to attack a specific person or group, even when the other groups have the problem just as much, e.g. complaining about the problem of Chinese robbers without providing evidence that Chinese people are more likely to be robbers than other groups. It was first described by blogger Alyssa Vance in 2015.
CultureWarRoundup / CWR: A splinter community of the Motte that lives at the subreddit /r/CultureWarRoundup, founded primarily by users who felt that the Motte's moderation policies were too strict. It has very little moderation.
Effective Altruism / EA : A philosophical and social movement that aims to use evidence and reason to do the most good possible. It has a lot of overlap with the rationalist community and LessWrong and experienced much of its early growth on LessWrong.
Human Biodiversity / HBD: A viewpoint that holds that there are socially relevant differences between groups of people that are genetic in origin. Most controversially, HBD advocates generally maintain that the observed differences between the average intelligence of people of different races originate in genetics.
Ideological Turing Test / ITT: An exercise where you try to pretend to hold an opposing ideology convincingly enough that outside observers can't reliably distinguish you from a true believer. It was first described by economist Bryan Caplan in 2011.
LessWrong: A discussion forum founded by AI theorist Eliezer Yudkowsky in 2009. The forum focuses on cognitive biases, rationality, artificial intelligence, and other topics. It is the primary nexus for the so-called “rationalist community.” LessWrong could be considered an ancestor forum to the Motte, since Scott Alexander blogged there before founding Slate Star Codex and this community originated in the subreddit for Slate Star Codex.
Lizardman's Constant: The share of the population (around 4%) who gives absurd responses in opinion polls (such as saying that lizardmen run the world); perhaps a combination of trolls, people who don't understand the question, people who just want to agree with the pollster, and people who are completely apathetic to the poll. It was coined by Scott Alexander in Lizardman's Constant is 4% (2013).
Motte and Bailey fallacy: A dishonest form of argument where one conflates two positions, one easy to defend but with limited implications (the motte) and another hard to defend but with far-reaching implications (the bailey). The fallacy was named after a kind of castle. It was coined by the philosopher Nicholas Shakel in 2005 and popularized by Scott Alexander via Social Justice and Words, Words, Words (2014) and All in All, Another Brick in the Motte (2014). The motte-and-bailey fallacy is the namesake of the Motte; in this community, we would like people to only hold positions that they can defend.
Neoreaction / NRx: A right-wing political philosophy whose signature viewpoint is that monarchy is a better form of government than democracy. Its most famous advocate is the blogger Curtis Yarvin, aka Mencius Moldbug. The neoreactionary movement first grew on LessWrong, although they were always a very small faction there.
Prior: A term from Bayesian Statistics that essentially means one's belief about something before they take new evidence into account. To say that one's prior is X is essentially to say that one's belief is X. To say that one has "adjusted their priors" is essentially to say that one has changed one's mind to some degree about the topic at hand based on the evidence presented; in theory this is done by applying Bayes' theorem.
Quokka: A kind of Australian macropod. They have no natural predators and are therefore not particularly fearful. Some people, beginning with a 2020 Twitter thread by “Zero HP Lovecraft”, who believe rationalists are too trusting or naive compare rationalists to Quokkas.
Rationalist: An online community of people originally formed around the blog Overcoming Bias, founded in 2006 by economist Robin Hanson and AI theorist Eliezer Yudkowsky; the discussion forum LessWrong, founded in 2009 by Yudkowsky; and the blog Slate Star Codex, founded in 2013 by Scott Alexander. The rationalist community is generally focused on cognitive bias and reason. Because the Motte originated in the subreddit for Slate Star Codex, it could be considered part of a rationalist “diaspora.”
rDrama: A humorous forum about Internet drama. Originally the subreddit /r/drama, the community now lives at rdrama.net. The Motte forked the code they use to run their site when we moved from Reddit to this website in 2022 because it was a proven example of a Reddit community successfully moving offsite and had many of the features we wanted.
Red Tribe / Blue Tribe / Gray Tribe: Terms used to describe different cultural groups in America. The terms were coined by Scott Alexander in I Can Tolerate Anything Except the Outgroup (2014). They are sometimes used interchangeably with the concepts of Republicans (Red Tribe) and Democrats (Blue Tribe), but in their original conception, Red Tribe (or Blue Tribe) meant something more precisely stated as “the sorts of people likely to be Republicans (or Democrats), regardless of their actual political views.” For example, a vegan Harvard graduate who lives in Manhattan and loves musical theater is part of the Blue Tribe even if he is actually politically conservative. The Gray Tribe is a sub-tribe of the Blue Tribe characterized by things like working in STEM fields and often having libertarian-ish politics.
Scissor Statement: A highly controversial statement that reliably provokes arguments. Coined by Scott Alexander in Sort By Controversial (2018), a work of fiction in which scissor statements are generated by a machine learning system trained on Reddit comments.
Slate Star Codex / SSC / Astral Codex Ten / Scott Alexander: Scott Alexander is a psychiatrist who lives in the Bay
Area. He blogged from 2013-2020 at Slate Star Codex and since 2021 at Astral Codex Ten. The Motte was created as a subreddit in 2019 as the home for a weekly "culture war roundup" thread that was hosted on the subreddit for SSC until then. The culture war roundup threads were removed from /r/slatestarcodex at Scott Alexander’s request. Scott Alexander’s writings are a major influence on the norms of this community. His blog and the community around it are generally considered part of the rationalist community. Scott Alexander was a popular writer at LessWrong before founding SSC and the community around SSC has a lot of overlap with LessWrong.
SneerClub: A community of people critical of the rationalist community, including the Motte, that lives at the subreddit /r/SneerClub.
Steelman: The strongest possible form of an opposing argument; the opposite of a strawman.
TheSchism: A splinter community of the Motte founded in 2020 that lives at the subreddit /r/TheSchism.
Weakman: A weak argument that someone has actually made (so it’s not a strawman). A poor form of argument is to choose the weakest argument that someone has actually made in favor of a position and argue against that while ignoring stronger arguments for that position.
