Living Fossils 20 implied HN points 11 Mar 26
  1. The most reliable psychology comes from explicit, quantitative, testable models—like laws of learning and signal detection—that make precise predictions and connect to other sciences.
  2. Thinking about how minds evolved and work in real environments explains many supposed “biases” and shows family and kinship profoundly shape behavior. Simple heuristics are often fast, frugal, and adaptive rather than errors.
  3. Psychology needs clear, specific, and measurable claims that fit with other disciplines; vague or unfalsifiable ideas lead to error, so healthy skepticism and rigor matter.
Astral Codex Ten 14453 implied HN points 09 Jul 25
  1. Our brains don’t see the world directly. Instead, they create models based on our senses, which can sometimes be wrong, like seeing colors in an illusion.
  2. The 'self' we think of is more of a model our brain uses to organize thoughts and actions. This model isn't always accurate and doesn't always match up with what's actually happening in our minds.
  3. Experiences like trance or altered states can shift our perception of control. When someone is hypnotized, they might feel like they're no longer in control, showing how our mental models can change and influence our reality.
Webworm with David Farrier 11301 implied HN points 05 Feb 24
  1. With the rise of AI-generated content and misinformation, we are losing the ability to distinguish reality from fiction on social media.
  2. Our online experiences are increasingly filled with unrealistic and manipulated images and stories that shape our perceptions.
  3. There is a growing concern that the blurred lines between reality and non-reality online are impacting important real-world decisions and behaviors.
Atlas of Wonders and Monsters 339 implied HN points 17 Jan 26
  1. The Sun can look pale, moon-like, and surprisingly painless to stare at when it sits behind a thin, translucent layer of cloud; the solar disc can still appear well defined even though its brightness is much reduced.
  2. There is no widely accepted name for this common-but-unremarked phenomenon, so ordinary search terms return noisy or unrelated results; short candidates that work best include "pale sun," "overcast sun," or "filtered sun."
  3. Both scientific studies and painters have noted similar muted-sun effects—science uses phrases like "filtered sun" or "sharp-edged sun" while art sometimes depicts dull, moonlike discs—but the effect is lightly studied and not an established concept, so broader use and shared photos could help a canonical name emerge.
Uncharted Territories 6682 implied HN points 20 Apr 23
  1. Maps can distort our perception of the world due to the 2D representation of a 3D sphere
  2. Many countries and regions on maps appear different in size and proximity than in reality
  3. Different map projections can show completely different relationships between regions

Fake Noûs 194 implied HN points 17 Jan 26
  1. Perceptual experiences can directly justify beliefs without needing further reasons, so conscious appearances stop the regress rather than forcing an infinite chain or vicious circularity.
  2. You needn't first prove a method's reliability before using it; basic belief-forming methods (like perception, memory, and reasoning) can be rational starting points, and some epistemic circularity is acceptable for knowing they work.
  3. We are directly aware of external objects through perception, so we don't have to infer that impressions are mere signs of things — direct perception provides immediate justification for beliefs about the world.
Wrong Side of History 436 implied HN points 02 Dec 25
  1. Many Americans have a negative view of Britain, often based on exaggerated stories and online videos. They may think Britain is chaotic, even though it's generally safer than many American cities.
  2. Short-form videos online have changed how people see Britain, showing negative images that create a gloomy impression. This differs from the more positive views that came from British cultural exports like movies and music.
  3. The proliferation of decline-themed content on social media feeds into these negative perceptions. It's important to recognize that much of what people see doesn't paint the full picture of life in Britain.
Eucatastrophologist 1218 implied HN points 01 Feb 24
  1. Different perspectives exist and disagreements are normal, it's important to be aware of popular trends of thinking
  2. The demon of demythologisation is about interpreting the world in a fixed way, stripping away mystery

  1. The world is described as a place filled with engineered plagues and masks as symbols of love.
  2. There is a critique on society where the rich thrive and the poor are content with their circumstances.
  3. The text raises the idea that intelligence is now manufactured to serve human needs.
Fake Noûs 224 implied HN points 29 Nov 25
  1. Perception gives direct, non-inferential awareness of external objects when a perceptual experience assertively represents the world and that representation is roughly satisfied and non-accidentally caused by the object.
  2. Perceptual experiences are internal states that have representational content, qualitative character, and a forceful feeling of presence; they are the vehicles that present the external world to us and are what differ in hallucinations or illusions.
  3. Treating experiences as the objects of awareness rather than as the vehicles of awareness is a mistake that leads to indirect realism, skepticism, or idealism; correctly understood, experiences enable direct awareness of real external things.
Fake Noûs 129 implied HN points 27 Dec 25
  1. Positing sense data creates a serious location problem: they can’t plausibly be in your head, at the external object, wherever they appear, or in a separate “phenomenal space” without contradictions or conflicts with physics.
  2. Percepts often appear indeterminate (e.g. vague colors or unreadable distant text), yet nothing can truly have indeterminate properties, so we can’t be directly aware of mind-dependent objects that exactly match these indeterminate appearances.
  3. The better view is that perception directly presents ordinary physical objects and properties, while our perceptual states sometimes represent those objects imprecisely rather than revealing separate sense-data entities.
Fake Noûs 165 implied HN points 13 Dec 25
  1. Many standard objections confuse appearance with ontology: apparent size changes, a stick looking bent, or double vision can be explained by physical factors like angular size, refraction, or distortion and don’t prove we perceive non-physical intermediaries.
  2. Hallucinations and illusions don’t show that normal perception is of mental images: hallucinations aren’t genuine awareness, and what justifies belief in perception is that things seem to be a certain way, not evidence of mental objects.
  3. Causal delays and debates about qualities like color don’t defeat direct realism: colors can be treated as physical spectral properties, and time lags mean we see objects as they were rather than seeing only mental entities.
The Free Mind 1611 implied HN points 07 Mar 23
  1. People want to believe lockdown was for the greater good, even when evidence of manipulation is clear.
  2. Cognitive dissonance can make us deny, minimize, or rationalize uncomfortable truths.
  3. Lockdown may have influenced how people perceived the severity of Covid risk, based on government actions.
lifeboat 786 implied HN points 06 Dec 23
  1. The color of water can be a blend of various colors like bronze, blue, umber, pink, gold, and silver.
  2. Different cultures and languages may perceive and name colors differently, affecting how we see and describe the world.
  3. Words and language can both reveal and limit our understanding of the world, especially when it comes to describing the ever-changing colors of water.
The Memory Palace 139 implied HN points 30 Apr 24
  1. Memory shouldn't be judged the same way as perception. Just because we can't remember everything perfectly doesn't mean our memory is faulty.
  2. Instead of thinking about memory accuracy, we should look at how well a memory represents something. This means we can accept changes in how memories are formed and recalled.
  3. Unique aspects of memories, like 'authenticity,' might not be the best standard to evaluate them. Instead, we should focus on how memories succeed in representing our experiences in various ways.

UX Psychology 218 implied HN points 30 Mar 23
  1. Research indicates that people generally prefer curved lines over straight or angular ones due to associations with grace and gentleness.
  2. Preference for curves is not just psychological, but has roots in our perception of safety and nurture, related to our evolutionary past.
  3. In design, understanding people's preference for curved lines can help create more visually appealing and effective products, but individual factors like personality and culture also play a role.
Desk Notes by Charles Schifano 109 implied HN points 27 Jun 25
  1. People used to ask for directions more often, but now everyone has maps on their phones. This change means fewer chances for random, friendly interactions in public.
  2. There’s a balance between being aware of risks in the world and being open to meeting new people. Too much caution can make you miss out on connections.
  3. It's important to not let fear take over your life. While you should be aware of dangers, focusing only on risks can stop you from enjoying life fully.
polymathematics 39 implied HN points 02 May 24
  1. A strong identity is colorful and rich, making life more enjoyable. It's important to explore different interests and keep a record of experiences, but identity shouldn't be fragile or too dependent on others' opinions.
  2. Sometimes we feel possessive over our ideas or hobbies, but we shouldn't let that dictate our feelings of self-worth. Remember, our identity is not defined by how others see us or what they think about our work.
  3. Focusing on what truly matters to us in the long term helps keep our identity grounded. We should prioritize doing what we love and building connections with creative, curious people, regardless of outside recognition.
