Scott Alexander reports on a 1990s Buddhist sun miracle in Bangkok that closely resembles the famous 1917 Fatima miracle, suggesting sun miracles may be a specific psychological phenomenon related to meditation practices rather than divine intervention. Longer summary

Scott Alexander discusses a newly discovered 1990s Buddhist sun miracle in Bangkok that closely parallels the famous 1917 Fatima sun miracle in Portugal, where crowds reported seeing the sun spin and change colors. At the Dhammakaya Temple, 20,000 people witnessed similar phenomena during a ceremony, with testimonies describing the sun rotating, shifting colors, and displaying visions of their sect's founder. Scott argues this Buddhist case - occurring in an 'uncontaminated' religious context - strengthens the theory that sun miracles are a particular psychological/illusory phenomenon rather than divine intervention or simple suggestion, possibly related to kasina meditation practices. The post includes a call for Thai-speaking researchers to investigate further. Shorter summary

Scott explains the Buddhist claim that 'life is suffering' through a temperature analogy: just as cold is merely the absence of heat, joy is merely less suffering, with nirvana being 'absolute zero suffering' rather than a neutral state. Longer summary

Scott explores the Buddhist claim that 'life is suffering' by explaining it through an analogy with temperature: just as scientifically there is only heat (with cold being merely the absence of heat), Buddhists claim there is only suffering (with joy being merely less suffering than baseline). The post addresses the common objection that Buddhism seems to reject life's good experiences, explaining that nirvana isn't a gray neutral state but rather 'absolute zero suffering' - more blissful than ordinary happiness, just as absolute zero is colder than room temperature. Scott connects this to previous discussions about jhanas, meditation, and the symmetry theory of valence, where irregularity in brain activity corresponds to suffering. Shorter summary

Scott explores reader responses to his Fatima miracle post, finding the most promising explanation in Buddhist fire kasina meditation practices that produce similar visual phenomena, while remaining uncertain about how 70,000 untrained people could achieve advanced meditative states instantly. Longer summary

Scott discusses reader responses to his previous post about the Fatima sun miracle, exploring new theories and evidence. The most promising explanation connects the phenomenon to 'fire kasina' meditation, a Buddhist practice of staring at bright lights that produces similar visual effects including spinning, color changes, and complex imagery. He examines the parallel case of Iranians seeing Ayatollah Khomeini's face in the moon in 1978, analyzes various videos of modern sun miracles (concluding they're camera artifacts), interviews a Medjugorje witness, and engages with Ethan Muse's counterarguments about the miracle being an objective phenomenon. Scott also addresses philosophical questions about miracles and Bayesian reasoning, ultimately remaining uncertain but slightly less confused than before, with fire kasina providing the best but still imperfect explanation. Shorter summary

Scott analyzes misophonia through new research and personal experience, suggesting it might be maintained by complex emotional and social networks rather than pure sound sensitivity. Longer summary

Scott discusses misophonia, a condition where people are extremely intolerant of certain sounds, through the lens of new research suggesting it's not just about sensory sensitivity. He explores evidence showing misophonia persists in deaf people, depends heavily on context, and is often worse with close relations. Through his personal experience with the condition, he proposes that misophonia might be sustained by a complex network of anger, social context, and identity, rather than pure sensory overload. He connects this to his previous work on trapped priors, suggesting the condition persists because these networks prevent normal updating of emotional responses. Shorter summary

Daniel Böttger proposes a new theory of consciousness as recursive reflections of neural oscillations, explaining qualia and suggesting experimental tests. Longer summary

This guest post by Daniel Böttger proposes a new theory of consciousness, describing it as recursive reflections of neural oscillations. The theory posits that qualia arise from the internal processing of information within oscillating neural patterns, which can reflect on themselves. The post explains how this theory accounts for various characteristics of qualia and consciousness, and suggests ways to test the theory using EEG source analysis. Shorter summary

Scott Alexander explores various explanations for why some people don't respond to 'woo' practices, questioning whether non-responders are defective or if woo itself might be ineffective or even harmful. Longer summary

Scott Alexander discusses the concept of 'woo' (alternative wellness and spirituality practices) and explores different possibilities for why some people might not respond to these practices. He presents four possibilities: 1) Woo is universally great but harder for some people due to being 'dissociated from bodily experiences', 2) Different people process emotions differently and woo works better for some than others, 3) Woo treats a specific defect of storing emotions in the body, and 4) Woo correlates with a specific defect but doesn't actually help. Scott provides evidence and counterarguments for each possibility, drawing on psychological theories, cross-cultural observations, and personal anecdotes. He concludes by highlighting the difficulty in determining whether practices like woo are helpful coping mechanisms or potentially harmful risk factors for mentally unhealthy individuals. Shorter summary

Scott Alexander explores whether people can be honestly mistaken about their own experiences, presenting counterexamples and attempting to reconcile them with the idea that we can't be wrong about our immediate subjective experiences. Longer summary

Scott Alexander discusses the concept of whether people can be honestly wrong about their own experiences. He initially asserts that people can't be wrong about their own experience, only lying or telling the truth. However, he then explores several counterexamples and edge cases that challenge this view. These include instances of hunger not being consciously felt, time perception on drugs, a woman claiming to be enlightened but unaware of her thoughts, optical illusions, and psychedelic experiences. Scott attempts to reconcile these examples with his initial assertion by differentiating between subjective experiences and underlying realities. He concludes by acknowledging the difficulty in maintaining his original position, while still feeling that there's something fundamentally true about the idea that we can't be wrong about our immediate experiences.

Scott Alexander summarizes comments debating the reality and implications of jhanas, a meditative state of extreme bliss. Longer summary

Scott Alexander reviews and summarizes comments on his previous post about jhanas, a meditative state of extreme bliss. He discusses the debate over whether jhanas are real, how they compare to other pleasures like sex, whether they can substitute for other pleasures, what science says about them, and whether pursuing jhanas is good or bad. The post includes many quotes from commenters sharing their own experiences with jhanas and opinions on the topic. Shorter summary

Scott Alexander examines the Buddhist concept of jhana, a blissful meditative state, through Nick Cammarata's experiences, exploring its implications for understanding pleasure and reinforcement. Longer summary

Scott Alexander discusses the concept of jhana, a state of extreme bliss achieved through meditation in Buddhism. He focuses on Nick Cammarata's experiences with jhana, describing it as incredibly pleasurable yet non-addictive. The post explores the paradox of jhana being more pleasurable than sex but less reinforcing, challenging conventional models of reward and pleasure. Scott also mentions the Qualia Research Institute's approach to understanding these phenomena and poses discussion questions about the nature of pleasure, reinforcement, and decision-making in relation to jhana. Shorter summary

Scott reviews 'Rhythms Of The Brain', exploring the nature and potential significance of brain waves in neuroscience and consciousness. Longer summary

Scott reviews 'Rhythms Of The Brain' by Gyorgy Buzsaki, exploring the nature and potential significance of brain waves. He discusses why brains produce oscillations, the characteristics of these waves, their possible functions, and speculates on their relationship to consciousness and spiritual experiences. The review concludes with thoughts on how the absence of brain-wave equivalents in AI might affect their development of consciousness or selfhood. Shorter summary

Scott explores the connection between the Dark Room Problem in neuroscience, meditative jhanas, and theories of beauty, suggesting that intense focus on regular stimuli can produce extreme bliss. Longer summary

Scott Alexander discusses the Dark Room Problem in neuroscience and its connection to meditative states known as jhanas. He explores the idea that sitting quietly in a dark room, or focusing intently on a single stimulus, can lead to extreme bliss. This perspective, shared by Andrés Gómez Emilsson, suggests that regularity, predictability, and symmetry in stimuli can produce intense pleasure when one can concentrate deeply enough. The post compares this to theories of beauty and discusses how it might explain the appeal of music and other forms of art. Shorter summary

The review critically examines and then steelmans Robert Wright's claims about meditation and enlightenment in 'Why Buddhism Is True', concluding with personal reflections on meditation's effects. Longer summary

This review of Robert Wright's 'Why Buddhism Is True' explores the book's central claim that meditation can free us from evolutionary illusions and lead to enlightenment. The reviewer initially presents a critical view, questioning whether Wright's version of enlightenment might lead to a nihilistic state. However, the review then steelmans Wright's arguments, suggesting that meditation could potentially lead to a more morally aware state by strengthening 'calm passions' and removing craving and aversion. The reviewer concludes by sharing personal experiences from a meditation retreat that align with Wright's more optimistic vision, while acknowledging the subjective nature of these experiences. Shorter summary

Scott Alexander examines a theory proposing that depression, anxiety, and trauma are characterized by low precision of sensory evidence, leading to overreliance on negative priors. Longer summary

Scott Alexander discusses a paper by Van der Bergh et al. that proposes a unified theory of negative emotionality, including depression, anxiety, and trauma. The theory suggests that these conditions are characterized by a processing style that assigns unusually low precision to sensory evidence, leading to an overreliance on negative priors. Scott explores the implications of this theory, including its support for various psychotherapies, somatic therapies, and meditation. He also discusses potential pharmacological interventions and how this model ties together various concepts in psychiatry and predictive processing. Shorter summary

A fictional story about the last unenlightened man's resistance and eventual enlightenment in a world where everyone else has achieved enlightenment. Longer summary

This post is a fictional story about a man who resists enlightenment in a world where everyone else has achieved it through a movement called Golden Lotus. The protagonist becomes the last unenlightened person and is confined to a small area to protect him from enlightenment. He develops his own practice of 'samsara' to counteract the enlightenment efforts. Over time, he gains disciples who want to learn samsara, but it turns out to be a ruse to gradually lead him towards enlightenment. The story ends with the protagonist finally becoming enlightened, realizing that his resistance and attempts to teach samsara were part of his path to enlightenment all along. Shorter summary

Scott Alexander examines skeptical and supportive comments on claims of enlightenment, arguing that evidence for such states is comparable to other accepted mental phenomena. Longer summary

This post discusses the comments on a previous article about Persistent Non-Symbolic Experience (PNSE) or 'enlightenment'. Scott Alexander addresses skepticism towards claims of enlightenment, comparing it to other mental states and discussing the evidence for its existence. He argues that the evidence for enlightenment-like states is as strong as for many other accepted mental phenomena. The post also explores different perspectives on enlightenment, including potential criticisms and alternative explanations, as well as personal accounts from individuals with meditation experience. Shorter summary

Scott Alexander reviews a study on 'enlightenment', finding it involves internal changes in self-perception and cognition, often without noticeable external effects. Longer summary

Scott Alexander reviews a paper by Jeffery Martin on Persistent Non-Symbolic Experience (PNSE), a scientific term for enlightenment. The study interviewed 50 self-reported 'enlightened' individuals, finding common experiences like changes in sense of self, cognition, and perception. Notably, these internal changes often didn't affect external behavior significantly. The paper highlights discrepancies between participants' self-reported experiences and observable reality, such as claims of no stress contradicted by physical signs. Scott appreciates the paper for providing a minimalist account of enlightenment, suggesting it's more about altered internal experience than drastic personality changes or superhuman abilities. Shorter summary

Scott Alexander examines the compatibility of enlightenment with sex scandals, using recent Buddhist teacher scandals as a starting point for broader questions about consciousness and social conditioning. Longer summary

Scott Alexander discusses the recent sex scandal involving Buddhist teacher Culadasa and explores its implications for the concept of enlightenment. He notes that many prominent Buddhist teachers, despite claims of enlightenment, have been involved in similar scandals. The post questions whether enlightenment is compatible with such behavior, and examines various theories about why these scandals occur. Scott suggests that meditation might 'dissolve social conditioning' without necessarily replacing it with compassion. He draws parallels to other consciousness-altering practices and wonders if there are advantages to our usual state of consciousness that these practices might disrupt. Shorter summary

Scott reviews a paper proposing that psychedelics work by relaxing priors in the brain, potentially treating mental illness but also risking side effects. Longer summary

This post reviews a paper by Friston and Carhart-Harris that uses predictive coding theory to explain the effects of psychedelic drugs. The authors argue that psychedelics 'relax' priors in the brain, allowing for new perspectives and potential therapeutic benefits. They suggest this mechanism could help treat most mental illnesses by allowing patients to break free from maladaptive priors. The post discusses the theory's implications, including potential downsides like HPPD and increased belief in pseudoscience. It also mentions connections to meditation and prior work by other researchers. Shorter summary

Scott Alexander reviews 'The Mind Illuminated', a Buddhist meditation guide by Culadasa, praising its clarity while questioning some of its optimistic claims about meditation progress and risks. Longer summary

This post reviews 'The Mind Illuminated', a guide to Buddhist meditation by Culadasa. The book divides meditation into ten stages, focusing on concentration meditation. It presents a model of the mind based on 'subminds' and consciousness as a shared space, similar to global workspace theory. The author praises the book's clarity and care in explaining concepts, but questions some of its optimistic claims about the speed of attaining meditative mastery. The review compares Culadasa's approach to other meditation teachers, particularly regarding the potential risks of meditation like the 'Dark Night'. Overall, the reviewer finds Culadasa's optimism justified, likening meditation to a beneficial practice with fewer side effects than many medications. Shorter summary

Scott Alexander uses the Jewish legend of the Chamber of Guf as a metaphor for subconscious thoughts, exploring its implications for behavior, OCD, and self-defeating thoughts. Longer summary

Scott Alexander discusses the concept of the Chamber of Guf, a Jewish legend about a pit of proto-souls, and uses it as a metaphor for subconscious thoughts. He explores how this relates to behavior selection in the brain, the effects of dopamine on thought patterns, and various forms of OCD. The post delves into how anxiety can affect thought selection, leading to conditions like Gay OCD, and suggests that similar processes might be behind self-defeating thoughts. Scott also touches on how meditation might allow direct access to this subconscious realm of thoughts. Shorter summary

Scott Alexander examines Vinay Gupta's ideas on enlightenment, comparing them with other sources and discussing the challenges of interpreting mystical experiences from a scientific viewpoint. Longer summary

Scott Alexander discusses Vinay Gupta's views on enlightenment, comparing them to other sources like 'Mastering The Core Teachings Of The Buddha'. He notes similarities in descriptions of meditation and consciousness across different sources, but also highlights Gupta's assertion that everyone experiences enlightenment differently based on their cultural context. The post explores the challenges of understanding enlightenment from a scientific perspective and the potential relativism of mystical experiences. Scott also touches on the concept of the Bayesian brain and how it might relate to enlightenment experiences. He expresses skepticism about claims linking Western alchemical traditions to Eastern enlightenment practices and concludes with Gupta's personal account of achieving a state of no internal dialogue through meditation. Shorter summary

Scott Alexander explores meditative states as feedback loops, discussing jhanas from Buddhist practice and why most people don't experience runaway emotional feedback in everyday life. Longer summary

Scott Alexander discusses meditative states as feedback loops, referring to his previous post 'Going Loopy'. He explains that people don't usually enter runaway emotional feedback loops due to their inability to concentrate for long periods. The post then explores the concept of jhanas, advanced meditative states described in Leigh Brasington's book 'Right Concentration'. The first jhana is described as an intense state of pleasure achieved through concentration meditation. Brasington explains this state as a positive feedback loop of pleasure, similar to audio feedback but with pleasant sensations. Scott suggests that other jhanas might work similarly, with the fourth jhana being a state of ultimate calm achieved through a feedback loop of calmness. The post concludes by noting that non-meditators can't achieve these states because they lack the necessary concentration skills to maintain self-referentiality. Shorter summary

Scott Alexander reviews 'Mastering The Core Teachings Of The Buddha', a practical guide to Buddhist meditation that details the stages of insight and debunks common myths about enlightenment. Longer summary

Scott Alexander reviews 'Mastering The Core Teachings Of The Buddha' by Daniel Ingram, an emergency physician who claims to have achieved enlightenment. The book provides a practical, no-nonsense approach to Buddhist meditation, detailing the stages of insight and their effects. It breaks down Buddhism into three teachings: morality, concentration, and wisdom. The review explores the book's explanation of meditation techniques, the stages of insight (including the challenging 'Dark Night of the Soul'), and the nature of enlightenment. Scott also discusses the book's debunking of common myths about enlightenment and questions why one would pursue this path given its potential difficulties. The review concludes by drawing parallels between the book's descriptions of meditation experiences and concepts from cognitive science. Shorter summary

Scott Alexander hypothesizes that mystical experiences, hallucinations, and paranoia might be linked to an overactive pattern-matching faculty in the brain. Longer summary

Scott Alexander explores the relationship between mysticism, pattern-matching, and mental health. He suggests that hallucinations, paranoia, and mystical experiences might all be related to an overactive pattern-matching faculty in the brain. The post begins by discussing how the brain's failure modes differ from computers, then explains top-down processing and pattern matching using visual examples. It then connects these concepts to hallucinations, paranoia, and mystical experiences. Scott proposes that certain practices like meditation, drug use, and religious rituals may strengthen the pattern-matching faculty, leading to experiences of universal connectedness or enlightenment. He acknowledges that this hypothesis doesn't explain all aspects of mystical experiences and their benefits. Shorter summary
