Episodes

  1. Prospiracy Theories

    [Title from this unrelated story or this unrelated essay] Last week I wrote about how conspiracy theories spread so much faster on Facebook than debunkings of those same theories. A few commenters chimed in to say that of course this was true, the conspiracy theories had evolved into an...

  2. Meaningful

    [With apologies to Putnam, Pope, and all of you] Two children are reading a text written by an AI: The hobbits splashed water in each other’s faces until they were both sopping wet One child says to the other “Wow! After reading some text, the AI understands what water is!” The second child says...

  3. In Mod We Trust

    The Verge writes a story (an exposé?) on the Facebook-moderation industry. It goes through the standard ways it maltreats its employees: low pay, limited bathroom breaks, awful managers – and then into some not-so-standard ones. Mods have to read (or watch) all of the worst things people post on...

  4. Wage Stagnation: Much More Than You Wanted to Know

    [Epistemic status: I am basing this on widely-accepted published research, but I can’t guarantee I’ve understood the research right or managed to emphasize/believe the right people. Some light editing to bring in important points people raised in the comments.] You all know this graph: Median…

  5. Rule Thinkers In, Not Out

    Imagine a black box which, when you pressed a button, would generate a scientific hypothesis. 50% of its hypotheses are false; 50% are true hypotheses as game-changing and elegant as relativity. Even despite the error rate, it’s easy to see this box would quickly surpass space capsules, da Vinci...

  6. RIP Culture War Thread

    [This post is having major technical issues. Some comments may not be appearing. If you can’t comment, please say so on the subreddit.] I. I Come To Praise Caesar, Not To Bury Him Several years ago, an SSC reader made an r/slatestarcodex subreddit for discussion of blog posts here and related...

  7. My Plagiarism

    I was going back over yesterday’s post, and something sounded familiar about this paragraph: A very careless plagiarist takes someone else’s work and copies it verbatim: “The mitochondria is the powerhouse of the cell”. A more careful plagiarist takes the work and changes a few words around: “The...

  8. GPT-2 as Step Toward General Intelligence

    A machine learning researcher writes me in response to yesterday’s post, saying: I still think GPT-2 is a brute-force statistical pattern matcher which blends up the internet and gives you back a slightly unappetizing slurry of it when asked. I resisted the urge to answer “Yeah, well, your mom is…

  9. Do Neural Nets Dream of Electric Hobbits?

    Last week OpenAI announced its latest breakthrough. GPT-2 is a language model that can write essays to a prompt, answer questions, and summarize longer works. For example (bold prompt is human-written, all other text is the machine-generated response): Prompt: For today’s homework assignment,...

  10. The Proverbial Murder Mystery

    I. Chefs. Hundreds of them. Tall chefs, short chefs, black chefs, white chefs. I pushed forward through them, like an explorer hacking away at undergrowth. They muttered curses at me, but I was stronger than they were. I came to a door. I opened it. Sweet empty space. I shut the door behind me…

  11. Survey Results on SSRIs

    SSRIs are the most widely used class of psychiatric medications, helpful for depression, anxiety, OCD, panic, PTSD, anger, and certain personality disorders (Why should the same drug treat all these things? Great question!) They’ve been pretty thoroughly studied, but there’s still a lot we don’t...

  12. Respectability Cascades

    I. I don’t know much about gay history, but the heavily mythicized version of it I heard goes like this: At first open homosexuality was totally taboo. A few groups of respectable people with hilariously upper-class names like The Mattachine Society and The Daughters Of Bilitis quietly tried to...

  13. Book Review: Zero to One

    I. Zero To One might be the first best-selling business book based on a Tumblr. Stanford student Blake Masters took Peter Thiel’s class on startups. He posted his notes on Tumblr after each lecture. They became a minor sensation. Thiel asked if he wanted to make them into a book together. He did....

  14. Predictions for 2019

    At the beginning of every year, I make predictions. At the end of every year, I score them. So here are a hundred more for 2019. Rules: all predictions about what will be true on January 1, 2020. Any that involve polling will be settled by the top poll or average of polls on Real Clear Politics…

  15. Psychiat-List Now Up

    Lots of people have asked me to recommend them a psychiatrist or therapist. I’ve done a terrible job responding: it’s a conflict of interest to recommend my own group, and I don’t know many people outside of it. So now I’ve put together a list (by which I mostly mean blatantly copied a similar…

  16. 2018 Predictions: Calibration Results

    At the beginning of every year, I make predictions. At the end of every year, I score them. Here are 2014, 2015, 2016, and 2017. And here are the predictions I made for 2018. Strikethrough’d are false. Intact are true. Italicized are getting thrown out because I can’t decide if they’re true or…

  17. Highlights from the Comments on Kuhn

    Thanks to everyone who commented on the review of The Structure Of Scientific Revolutions. From David Chapman: It’s important to remember that Kuhn wrote this seven decades ago. It was one of the most influential books of pop philosophy in the 1960s-70s, influencing the counterculture of the…

  18. Kernel of Doubt: Testing Math Preference vs. Corn-Eating Style

    In 2010, Ben Tilly of the blog Random Observations wrote Analysis Vs. Algebra Predicts Eating Corn?, which said: I like learning about odd connections between disparate things. This probably is the oddest example that I know. Broadly speaking, mathematicians can be divided into those who like...

  19. Too Many People Dare Call it Conspiracy

    [Content warning: References to anti-Semitic and anti-Catholic canards] I feel deep affection for Gary Allen’s None Dare Call It Conspiracy, a bizarre screed about the Federal Reserve/Communist/Trilateral Commission plot for a one world government. From its ridiculous title to its...

  20. SSC Survey Results 2019

    Thanks to the 8,171 people who took the 2019 Slate Star Codex survey. Some of the links below will say 13,171 people took the survey, but that’s a bug – sometimes Google just adds 5,000 to things. You can: – See the questions for the SSC survey. – See the results from the SSC survey. I’ll be...

  21. Paradigms All the Way Down

    Related to: Book Review: The Structure Of Scientific Revolutions Every good conspiracy theorist needs their own Grand Unified Chart; I’m a particular fan of this one. So far, my own Grand Unified Chart looks like this: All of these are examples of interpreting the world through a combination of...

  22. Book Review: The Structure of Scientific Revolutions

    When I hear scientists talk about Thomas Kuhn, he sounds very reasonable. Scientists have theories that guide their work. Sometimes they run into things their theories can’t explain. Then some genius develops a new theory, and scientists are guided by that one. So the cycle repeats, knowledge...

  23. Preregistration of Investigations for the 2019 SSC Survey

    This post is about the 2019 SSC Survey. If you’ve read at least one blog post here before, please take the surveyif you haven’t already. Please don’t read on until you’ve taken it, since this post could bias your results. 1. Can we confirm or disconfirm different corn-eating profiles of…

  24. What Happened to 90s Environmentalism?

    0. Introduction I grew up in the 90s, which meant watching movies about plucky children fighting Pollution Demons. Sometimes teachers would show them to us in class. None of us found that strange. We knew that when we grew up, this would be our fight: to take on the loggers and whalers and...

  25. Please Take the 2019 SSC Survey

    Please take the 2019 Slate Star Codex Survey. The survey helps me learn more about SSC readers and plan community events. But it also provides me with useful informal research data for questions I’m interested it, which I then turn into interesting posts. My favorite from last year was Fight Me,...

  26. Beware the Man of One Study

    Aquinas famously said: beware the man of one book. I would add: beware the man of one study. For example, take medical research. Suppose a certain drug is weakly effective against a certain disease. After a few years, a bunch of different research groups have gotten their hands on it and done all...

  27. Fallacies of Reversed Moderation

    A recent discussion: somebody asked why people in Silicon Valley thought that only high-tech solutions to climate change (like carbon capture or geoengineering) mattered, and why they dismissed more typical solutions like international cooperation and political activism. Another person cited...

  28. Refactoring: Culture as Branch of Government

    Ribbonfarm likes to talk about refactoring, a conceptual change in how you see the world. I’m not totally sure I understand it, but I think it means things like memetics – where you go from the usual model of people deciding what ideas they want, to a weird and inside-out (but not objectively...

  29. Trump: A Setback for Trumpism

    Donald Trump has been called a setback for many things. America. The global community. The environment. Civil service. Civil society. Civility. Civilization. The list goes on. One might think he has at least been useful to his own cause. That he could at least claim to have benefited the ideas of...

  30. Diametrical Model of Autism and Schizophrenia

    One interesting thing I took from Evolutionary Psychopathology was a better understanding of the diametrical theory of the social brain. There’s been a lot of discussion over whether schizophrenia is somehow the “opposite” of autism. Many of the genes that increase risk of autism decrease risk of...

  31. Del Giudice on the Self-Starvation Cycle

    [Content note: eating disorders] Anorexia has a cultural component. I’m usually reluctant to assume anything is cultural – every mediocre social scientist’s first instinct is always to come up with a cultural explanation which is simple, seductive, flattering to all our existing prejudices, and...

  32. Book Review: Evolutionary Psychopathology

    I. Evolutionary psychology is famous for having lots of stories that make sense but are hard to test. Psychiatry is famous for having mountains of experimental data but no idea what’s going on. Maybe if you added them together, they might make one healthy scientific field? Enter Evolutionary...

  33. Book Review: The Mind Illuminated

    I. The Mind Illuminated is a guide to Buddhist meditation by Culadasa, aka John Yates, a Buddhist meditation teacher who is also a neuroscience PhD. At this point I would be more impressed to meet a Buddhist meditation teacher who wasn’t a neuroscience PhD. If I ever teach Buddhist meditation…

  34. Is Science Slowing Down?

    [This post was up a few weeks ago before getting taken down for complicated reasons. They have been sorted out and I’m trying again.] Is scientific progress slowing down? I recently got a chance to attend a conference on this topic, centered around a paper by Bloom, Jones, Reenen & Webb (2018)....

  35. The Economic Perspective on Moral Standards

    [Content warning: scrupulosity] I. “There is no ethical consumption under late capitalism”. I hear this from a bunch of people. Sometimes it is taken to its conclusion; no currently living person is morally acceptable. People who aren’t activists reorienting their entire lives around…

    more
  36. Preschool: Much More Than You Wanted to Know

    I. A lot of people pushed back against my post on preschool, so it looks like we need to discuss this in more depth. A quick refresher: good randomized controlled trials have shown that preschools do not improve test scores in a lasting way. Sometimes test scores go up a little bit, but these...

  37. Ketamine: An Update

    In 2016, I wrote Ketamine Research In A New Light, which discussed the emerging consensus that, contra existing theory, ketamine’s rapid-acting antidepressant effects had nothing to do with NMDA at all. I discussed some experiments which suggested they might actually be due to a related receptor,...

  38. SSRIs: An Update

    Four years ago I examined the claim that SSRIs are little better than placebo. Since then, some of my thinking on this question has changed. First, we got Cipriani et al’s meta-analysis of anti-depressants. It avoids some of the pitfalls of Kirsch and comes to about the same conclusion. This…

    more
  39. Marijuana: An Update

    [Originally to be titled “Marijuana: I Was Wrong”, but looking back I was suitably careful about everything, and my reward is not having to say that.] Five years ago, I reviewed the potential costs and benefits of marijuana legalization and concluded that there wasn’t enough evidence for a firm...

  40. Preschool: I Was Wrong

    Kelsey Piper has written an article for Vox: Early Childhood Education Yields Big Benefits – Just Not The Ones You Think. I had previously followed various studies that showed that preschool does not increase academic skill, academic achievement, or IQ, and concluded that it was useless. In fact,...

  41. My California Ballot

    These are my preliminary choices for California elected positions and ballot initiatives. Some of them are based on Ozy’s recommendations and the Berkeley EA and rationalist community’s recommendations. I agree with the latter’s note that because California ballot propositions are weird superlaws...

  42. Working with Google Trends

    [Epistemic status: low. You tell me if you think this works.] Commenter no_bear_so_low has been doing some great work with Google Trends recently – see for example his Internet searches increasingly favour the left over the right wing of politics or Googling habits suggest we are getting a lot…

    more
  43. Sort by Controversial

    [Epistemic status: fiction] Thanks for letting me put my story on your blog. Mainstream media is crap and no one would have believed me anyway. This starts in September 2017. I was working for a small online ad startup. You know the ads on Facebook and Twitter? We tell companies how to get them…

    more
  44. Nominating Oneself for the Short End of a Tradeoff

    I’ve gotten a chance to discuss The Whole City Is Center with a few people now. They remain skeptical of the idea that anyone could “deserve” to have bad things happen to them, based on their personality traits or misdeeds. These people tend to imagine the pro-desert faction as going around,...

  45. Cognitive Enhancers: Mechanisms and Tradeoffs

    [Epistemic status: so, so, so speculative. I do not necessarily endorse taking any of the substances mentioned in this post.] There’s been recent interest in “smart drugs” said to enhance learning and memory. For example, from the Washington Post: When aficionados talk about nootropics, they...

  46. The Chamber of Guf

    [I briefly had a different piece up tonight discussing a conference, but the organizers asked me to hold off on writing about it until they’ve put up their own synopsis. It will be back up eventually; please accept this post instead for now.] In Jewish legend, the Chamber of Guf is a pit where…

    more
  47. Anxiety Sampler Kits

    The best thing about personalized medicine is that it’s obviously right. The worst thing is we mostly have no idea how to do it. We know that different people respond to different treatments. But outside a few special cases like cancer, we don’t know how to predict which treatment will work for...

  48. Kavanaugh: A Probability Poll

    There’s some literature suggesting that people are more careful when they think in probabilities. If you ask them for a definite answer, they might give it and sound very confident, but if you encourage them to think probabilistically they might admit there’s more uncertainty. I wanted to look…

    more
  49. Nighttime Ventilation Survey Results

    Thanks to the 129 people who tried altering their nighttime carbon dioxide levels after my post on this, and who reported back to me. There was no difference between people who pre-registered for the study and people who didn’t, on any variable, so I ignored pre-registration. 126 people reported...

  50. Next Door in Nodrumia

    [Content note: attempt to consider real people’s real problems using angel-on-pinhead impractical reasoning and ideas] I. Imagine the state of nature, except for some reason there are cities. Some people in these cities play the drums all night and keep everyone else awake. The sleep-deprived...
