The author, Bessel van der Kolk, helped discover the condition and lobby for its inclusion in the DSM, and the brief forays into that history are the best part of the book. Like so many things, PTSD feels self-evident once you know about it. But this took decades of conceptual work by people like van der Kolk, crystallizing some ideas and hacking away at others until they ended up with something legible to the Establishment. Before that there was nothing. It was absolutely shocking how much nothing there was. As soon as the APA officialy recognized PTSD as a diagnosis in 1980, Bessel and his friends applied for a grant from the VA to study it. The grant was rejected on the grounds that (actual quote from the rejection letter) "it has never been shown that PTSD is relevant to the mission of the Veterans Administration". So the first step in raising awareness of PTSD was – amazingly – convincing the US military that some people might get PTSD from combat. After the military relented, the next step was convincing everyone else. PTSD was temporarily pigeonholed as "the thing veterans get when they come back from a war". The next push was convincing people that civilian trauma could have similar effects. It was simple to extend the theory to sudden disasters like fires or violent crimes. But van der Kolk and his colleagues started noticing that a history of child abuse, and especially childhood sexual abuse, correlated with a lot of psychiatric problems later on.

This is 'post-empirical' science, where truth no longer matters, and it is potentially very dangerous. It's not difficult to find recent examples. On 8 June 2019, the front cover of New Scientist magazine boldly declared that we're 'Inside the Mirrorverse'. Its editors bid us 'Welcome to the parallel reality that's hiding in plain sight'. […] [Some physicists] claim that neutrons [are] flitting between parallel universes. They admit that the chances of proving this are 'low', or even 'zero', but it doesn't really matter. When it comes to grabbing attention, inviting that all-important click, or purchase, speculative metaphysics wins hands down. These theories are based on the notion that our Universe is not unique, that there exists a large number of other universes that somehow sit alongside or parallel to our own. For example, in the so-called Many-Worlds interpretation of quantum mechanics, there are universes containing our parallel selves, identical to us but for their different experiences of quantum physics. These theories are attractive to some few theoretical physicists and philosophers, but there is absolutely no empirical evidence for them. And, as it seems we can't ever experience these other universes, there will never be any evidence for them. As Broussard explained, these theories are sufficiently slippery to duck any kind of challenge that experimentalists might try to throw at them, and there's always someone happy to keep the idea alive. Is this really science? The answer depends on what you think society needs from science. In our post-truth age of casual lies, fake news and alternative facts, society is under extraordinary pressure from those pushing potentially dangerous antiscientific propaganda – ranging from climate-change denial to the anti-vaxxer movement to homeopathic medicines. I, for one, prefer a science that is rational and based on evidence, a science that is concerned with theories and empirical facts, a science that promotes the search for truth, no matter how transient or contingent. I prefer a science that does not readily admit theories so vague and slippery that empirical tests are either impossible or they mean absolutely nothing at all. As always, a single quote doesn't do the argument justice, so go read the article. But I think this captures the basic argument: multiverse theories are bad, because they're untestable, and untestable science is pseudoscience. Many great people, both philosophers of science and practicing scientists, have already discussed the problems with this point of view. But none of them lay out their argument in quite the way that makes the most sense to me. I want to do that here, without claiming any originality or special expertise in the subject, to see if it helps convince anyone else. II. Consider a classic example: modern paleontology does a good job at predicting dinosaur fossils. But the creationist explanation – Satan buried fake dinosaur fossils to mislead us – also predicts the same fossils (we assume Satan is good at disguising his existence, so that the lack of other strong evidence for Satan doesn't contradict the theory). What principles help us realize that the Satan hypothesis is obviously stupid and the usual paleontological one more plausible? One bad response: paleontology can better predict characteristics of dinosaur fossils, using arguments like "since plesiosaurs are aquatic, they will be found in areas that were underwater during the Mesozoic, but since tyrannosaurs are terrestrial, they will be found in areas that were on land", and this makes it better than the Satan hypothesis, which can only retrodict these characteristics. But this isn't quite true: since Satan is trying to fool us into believing the modern paleontology paradigm, he'll hide the fossils in ways that conform to its predictions, so we will predict plesiosaur fossils will only be found at sea – otherwise the gig would be up! A second bad response: "The hypothesis that all our findings were planted to deceive us bleeds into conspiracy theories and touches on the problem of skepticism. These things are inherently outside the realm of science." But archaeological findings are very often deliberate hoaxes planted to deceive archaeologists, and in practice archaeologists consider and test that hypothesis the same way they consider and test every other hypothesis. Rule this out by fiat and we have to accept Piltdown Man, or at least claim that the people arguing against the veracity of Piltdown Man were doing something other than Science. A third bad response: "Satan is supernatural and science is not allowed to consider supernatural explanations." Fine then, replace Satan with an alien. I think this is a stupid distinction – if demons really did interfere in earthly affairs, then we could investigate their actions using the same methods we use to investigate every other process. But this would take a long time to argue well, so for now let's just stick with the alien. A fourth bad response: "There is no empirical test that distinguishes the Satan hypothesis from the paleontology hypothesis, therefore the Satan hypothesis is inherently unfalsifiable and therefore pseudoscientific." But this can't be right. After all, there's no empirical test that distinguishes the paleontology hypothesis from the Satan hypothesis! If we call one of them pseudoscience based on their inseparability, we have to call the other one pseudoscience too! A naive Popperian (which maybe nobody really is) would have to stop here, and say that we predict dinosaur fossils will have such-and-such characteristics, but that questions like that process that drives this pattern – a long-dead ecosystem of actual dinosaurs, or the Devil planting dinosaur bones to deceive us – is a mystical question beyond the ability of Science to even conceivably solve. I think the correct response is to say that both theories explain the data, and one cannot empirically test which theory is true, but the paleontology theory is more elegant (I am tempted to say "simpler", but that might imply I have a rigorous mathematical definition of the form of simplicity involved, which I don't). It requires fewer other weird things to be true. It involves fewer other hidden variables. It transforms our worldview less. It gets a cleaner shave with Occam's Razor. This elegance is so important to us that it explains our vast preference for the first theory over the second. A long tradition of philosophers of science have already written eloquently about this, summed up by Sean Carroll here: What makes an explanation "the best." Thomas Kuhn ,after his influential book The Structure of Scientific Revolutions led many people to think of him as a relativist when it came to scientific claims, attempted to correct this misimpression by offering a list of criteria that scientists use in practice to judge one theory better than another one: accuracy, consistency, broad scope, simplicity, and fruitfulness. "Accuracy" (fitting the data) is one of these criteria, but by no means the sole one. Any working scientist can think of cases where each of these concepts has been invoked in favor of one theory or another. But there is no unambiguous algorithm according to which we can feed in these criteria, a list of theories, and a set of data, and expect the best theory to pop out. The way in which we judge scientific theories is inescapably reflective, messy, and human. That's the reality of how science is actually done; it's a matter of judgment, not of drawing bright lines between truth and falsity or science and non-science. Fortunately, in typical cases the accumulation of evidence eventually leaves only one viable theory in the eyes of most reasonable observers. The dinosaur hypothesis and the Satan hypothesis both fit the data, but the dinosaur hypothesis wins hands-down on simplicity. As Carroll predicts, most reasonable observers are able to converge on the same solution here, despite the philosophical complexity.

"Not interested," I said, preparing to slam the door in his face. "Please," said the acolyte. Before I could say no he'd jammed a wad of $100 bills into my hand. "If this will buy a few moments of your time." It did, if only because I stood too flabbergasted to move. Surely they didn't have enough money to do this for everybody. "There is no everybody," said the acolyte, when I expressed my bewilderment. "You're the last one. The last unenlightened person in the world." And it sort of made sense. Twenty years ago, a group of San Francisco hippie/yuppie/techie seekers had pared down the ancient techniques to their bare essentials, then optimized hard. A combination of drugs, meditation, and ecstatic dance that could catapult you to enlightenment in the space of a weekend retreat, 100% success rate. Their cult/movement/startup, the Order Of The Golden Lotus, spread like wildfire through California – a state where wildfires spread even faster than usual – and then on to the rest of the world. Soon investment bankers and soccer moms were showing up to book clubs talking about how they had grasped the peace beyond understanding and vanquished their ego-self.

Link: https://slatestarcodex.com/2013/09/12/the-life-cycle-of-medical-ideas/ I. About five years ago, an Italian surgeon with the unlikely name of Dr. Zamboni posited the theory that multiple sclerosis was caused by blockages in venous return from the brain causing various complicated downstream effects which eventually led to the immune system attacking myelinated cells. The guy was a good surgeon, nothing about the theory contradicted basic laws of biology, and no one else had any better ideas, so lots of people got excited. As far as I can tell, the medical community responded exactly one hundred percent correctly. They preached caution, urging multiple sclerosis patients not to develop false hope. But at the same time, they quickly launched studies investigating Zamboni's experiments and used newly gathered data to test the theory. All the results that came back made the idea look less and less likely, so that to my understanding by now it is pretty much discredited. Having successfully spent hundreds of thousands of dollars to empirically disconfirm Zamboni's hypothesis, we can now reflect at leisure on the reasons it was kind of dumb and we should have realized it all along.

Link: https://slatestarcodex.com/2019/10/30/new-atheism-the-godlessness-that-failed/ Thucydides predicted that future generations would underestimate the power of Sparta. It built no great temples, left no magnificent ruins. Absent any tangible signs of the sway it once held, memories of its past importance would sound like ridiculous exaggerations. This is how I feel about New Atheism. If I were to describe the power of New Atheism over online discourse to a teenager, they would never believe me. Why should they? Other intellectual movements have left indelible marks in the culture; the heyday of hippiedom may be long gone, but time travelers visiting 1969 would not be surprised by the extent of Woodstock. But I imagine the same travelers visiting 2005, logging on to the Internet, and holy @#$! that's a lot of atheism-related discourse what is going on here? My first forays onto the Internet were online bulletin boards about computer games. They would have a lot of little forums about various aspects of the games, plus two off-topic forums. One for discussion of atheism vs. religion. And the other for everything else. This was a common structure for websites in those days. You had to do it, or the atheism vs. religion discussions would take over everything. At the time, this seemed perfectly normal. In 2005, a college student made a webpage called The Church Of The Flying Spaghetti Monster. It was a joke based on the idea that there was no more scientific evidence for God or creationism than for belief in a flying spaghetti monster. The monster's website received tens of millions of visitors, 60,000 emails ("about 95 percent" supportive), and was covered in The New York Times, The Washington Post, and The Daily Telegraph. Six publishing companies entered a bidding war for the rights to the spaghetti monster's "gospel", with the winner, Random House, offering an $80,000 advance. The book was published to massive fanfare, sold over 100,000 copies, and was translated into multiple languages. Putin's thugs broke up a pro-Flying-Spaghetti-Monster demonstration in Russia. At the time, this seemed perfectly normal.

For the first time in history, the title actually understates the article, which argues that incentives can be surprisingly useless: Economists have somehow managed to hide in plain sight an enormously consequential finding from their research: Financial incentives are nowhere near as powerful as they are usually assumed to be. The article starts with some surprising facts. Increased taxes on the rich don't make rich people work much less. Salary caps on athletes don't decrease athletic performance. Increased welfare doesn't make poor people work less. Decreased job opportunities in one area rarely cause people to move elsewhere. Then it presents a neat chart showing that most people believe others would respond to an incentive, but deny responding to that incentive themselves. For example, 60% of people say a Medicaid program with no work requirement would prevent many people from seeking work, but only 10% of people say they themselves would stop seeking work with such a program.

Link: https://slatestarcodex.com/2019/10/24/highlights-from-the-comments-on-pnse/ (original post) Alex M writes: I think one of the main problems with the current state of rationalism (and many other fake "sciences" such as economics or sociology) is fuzzy thinking and lack of falsifiable empirical testing. So somebody claims to be "enlightened." Does a smart person take that at face value? Of course not. Once you just start believing random shit, you're no better than a superstitious primitive cargo-cult. You have to TEST all claims. For example, I don't just take it at face value that economics is a real science just because a bunch of IYIs tell me so. I analyze economist predictions, see that their track record of successful predictions is atrocious, and then make the totally RATIONAL choice to discard my priors and treats economics as the laughable hocus-pocus that it is – because when you genuinely have an accurate view of reality, it doesn't collapse under scrutiny. We should treat mystical claims exactly the same way. So somebody claims to be enlightened? Fine. How can they substantiate it? Can they do things that unenlightened people can't, like clairvoyance, predicting the future, or sending messages through the collective subconscious in order to significantly impact world events? Do you see what I'm saying? Enlightenment should have some objectively quantifiable impact beyond just having a different internal narrative that is completely subjective and unprovable.

Link: https://slatestarcodex.com/2019/10/23/indian-economic-reform-much-more-than-you-wanted-to-know/ From a recent Charter Cities Institute report: From India's independence from the British Raj in 1947 to the early 1990s, the country's economic policy was largely socialist. In the 1980s some early steps were taken to open the Indian economy to increased trade, reduce controls over industry, and set a more realistic exchange rate. In 1991, more widespread economic reforms were introduced. These reforms included the end of government monopolies over certain sectors of the economy, reductions in barriers to entry for new firms, increased foreign investment was allowed, and tariffs and other barriers to trade were reduced or eliminated. After liberalization, exports increased substantially, and various service sector industries saw significant growth. India's growth has not just been good for the more educated segment of the population. Datt, Ravallion, and Murgai (2016) argue that India has made substantial progress in reducing the incidence of absolute poverty, and that this trend exists in both urban and rural areas. Historically higher rates of rural poverty have been converging with urban rates of poverty, and the overall poverty rate has been declining at an accelerating rate in the post-1991 reform era. In the 1970s over 60 percent of Indians were living in extreme poverty. As of 2011, only 20 percent of the population lived in extreme poverty. Between 2005 and 2016, an estimated 271 million Indians rose out of multidimensional poverty, which accounts for various health, education, and living standard indicators rather than just income (UNDP and OPHI 2018). Infant mortality has fallen from 161.4 deaths per 1,000 births in 1960 to just 32 deaths per 1,000 births in 2017, and India should soon converge with the world average if the current trend continues. Life expectancy has also improved dramatically, rising from 41 years in 1960 to nearly 69 years today.

Link: https://slatestarcodex.com/2019/10/21/the-pnse-paper/ I've mentioned this a few times, but it's worth going over in detail. The full title is Clusters Of Individual Experiences Form A Continuum Of Persistent Non-Symbolic Experiences In Adults by Jeffery Martin, with "persistent non-symbolic experience" (PNSE) as a scientific-sounding culturally-neutral code word for "enlightenment". Martin is a Reiki practitioner associated with the "Center for the Study of Non-Symbolic Consciousness", so we're not getting this from the most sober of skeptics, but I still find the project interesting enough to deserve a look. Martin searched various religious and spiritual groups for people who both self-reported enlightenment and were affiliated with "a community that provided validity to their claims". He says he eventually found 1200 such people who were willing to participate in the study, but that "the data reported here comes primarily from the first 50 participants who sat for in-depth interviews…based on the overall research effort these 50 were felt to be a sufficient sample to represent what has been learned from the larger population". Although Martin says he tried to get as much diversity as possible, the group was mostly white male Americans. Martin's research was mostly qualitative, based on in-depth interviews, so we're mostly going with his impressions. But his impression was that most people who self-described as enlightened had similar experiences, which could be be plotted on:

Link: https://slatestarcodex.com/2019/10/16/is-enlightenment-compatible-with-sex-scandals/ Last year I reviewed The Mind Illuminated, a meditation guide by Buddhist teacher Upasaka Culadasa. Last month, Culudasa's Buddhist community accused him of cheating on his wife with prostitutes for many years. Culadasa doesn't seem to agree with the exact details of the accusations, but he also doesn't seem to deny that there was something in that general category of thing. What can this teach us about enlightenment? Culadasa has been meditating and studying Buddhism for over forty years and trained under some of the greatest teachers of his generation. I don't know if he's claimed to "be enlightened" in so many words, but he's written books that describe how to reach enlightenment and that assert you can do it in a few years if you follow his advice, which sounds a lot like claiming enlightenment by implication. Other self-proclaimed enlightened Buddhist teachers seem to respect him and treat him as being at around their level. And if Culudasa wasn't enlightened, there's a long list of other Buddhist masters with similar misdeeds. The Atlantic points out that three of the four great founders of American Zen "caused major public sex scandals"; the fourth, Shunryu Suzuki, was spotless, but his successor Richard Baker caused a major public sex scandal. The two most famous US teachers of Tibetan Buddhism, Chongyam Trungpa and Sogyal Rinpoche, both caused major public sex scandals. Trungpa's immediate successor Ösel Tendzin caused a particularly horrifying major public sex scandal, and the current head of Shambhala Buddhism, Sakyong Rinpoche, also caused a major public sex scandal. These teachers were among the most accomplished of our time. Many were officially certified as enlightened by
