What we read
Ayahuasca
ego dissolution. Ayahuasca's effects are complex, altering brain activity and self-perception. It can lead to profound insights and ego dissolution, but also intense anxiety if not approached with surrender.
Laws & Causes
Laws describe, causes explain. Physical laws don't cause things; they describe relationships. Explanations require understanding the mechanical causes behind phenomena, not just the mathematical correlations.
All The Ghosts You Will Be
You are forgotten when your name is last spoken and your physical traces fade. This happens in stages: your name (nominal ghost), your likeness (figural ghost), your genes (genetic ghost), and your actions' ripple effects (ripple ghost).
Selfie Waves
four waves of selfies. Selfies evolved through four waves: unintentional resemblances, deliberate self-portraits, accessible photography, and finally, the cultural phenomenon of the modern selfie. The word 'selfie' itself emerged in Australia in 2002.
Did People Used To Look Older?
lifestyle changes and fashion illusion. People today are aging more slowly due to lifestyle, nutrition, and healthcare improvements. However, much of the perception that people used to look older is an illusion caused by changing fashion trends and our own shifting perspectives.
Do Chairs Exist?
Chairs don't exist as physical objects. They are abstract concepts or 'sortals' that describe arrangements of matter, not distinct entities.
The Future Of Reasoning
social reasoning. Reasoning evolved for social interaction, not individual truth-seeking. Our brains are programmed to justify conclusions, not find them. The future of reason lies in collective deliberation, not lone thinkers.
Illusions of Time
brain constructs time. Time feels distorted because our brains construct it. We perceive time differently based on how 'full' or 'empty' an experience is, and how many distinct memories we form as we age. Our sense of time is also shaped by conceptual comparisons and how we mentally categorize events, not just their objective duration.
The Odd Number Rule
Odd number rule is constant acceleration. Gravity causes objects to accelerate at a constant rate, meaning they travel 1, 3, 5, 7... times farther in each successive second. This 'odd number rule' is just math, not magic.
How Many Holes Does a Human Have?
7 through-holes. The human body has 7 through-holes, not counting millions of blind holes like pores. These 7 through-holes are the GI tract, and 4 connections to the nasal cavity (mouth, nostrils, tear ducts).
What Is The Scariest Thing?
The scariest thing is elevated carbon dioxide in the blood caused by an uncontrollable external threat. This triggers primal fear responses even in people without an amygdala.
I Watch 3 Episodes of Mind Field With Our Experts & Researchers
improved spatial memory. Playing video games for 10 days improved spatial memory and navigation skills, even causing physical changes in the hippocampus. The effect was significant compared to a control group that did not play games.
Mind Reading
Yes, but not perfectly. Yes, it's possible to reconstruct images from brain activity, but not perfectly. Reconstructions from viewing images were better than from memory, and dream reconstructions are still blurry blobs.
Behavior and Belief
superstitious beliefs. Humans are susceptible to superstitious beliefs, creating rituals to feel in control when faced with uncertainty. Even fake rituals can induce real psychological experiences by leveraging expectations and powerful symbols.
How to Talk to Aliens
misinterpretation. They don't know. The video explores the difficulty of creating a universally understandable message for extraterrestrials, using a randomized 'Arecibo message' experiment to show how human biases lead to misinterpretations.
Should I Die?
accepting death. Accepting death is powerful. It gives life passion and meaning, and can lead to greater self-awareness and honesty, rather than denying it through wealth, power, or life extension.
The Stanford Prison Experiment
personality over situation. The Stanford Prison Experiment's conclusion that situational factors alone cause evil is likely false. New research suggests personality traits are more influential than previously believed.
The Stilwell Brain
human neural network. They built a human neural network on a football field. It successfully recognized handwritten digits by having hundreds of people act as neurons, passing signals through layers.
Moral Licensing
Moral licensing. Moral licensing is the subconscious tendency to do something bad after doing something good. It's often driven by a desire to maintain a balanced moral scorecard, not conscious calculation.
The Origins of Disgust
Primates evolved disgust to avoid parasites. Studies show macaques avoid food on feces, even when it's a preferred treat like peanuts. Touching feces triggered a stronger aversion than visual or smell cues.
The Cognitive Tradeoff Hypothesis
memory loss for language. Humans sacrificed detailed short-term memory for language. This "Cognitive Tradeoff Hypothesis" explains why chimps outperform us on memory tasks, but we gained the ability to communicate complex ideas.
The Electric Brain
brain-computer interfaces. The brain is electric. We can hack it to control bodies, restore movement, and even read minds. Experiments show we can control cockroaches with electrodes, and humans can move robotic limbs with their thoughts.
Divergent Minds
Studying divergent minds reveals universal brain functions.. Divergent minds, like those of autistic savants and people with brain injuries, reveal universal truths about the brain. Studying differences helps us understand the norm, showing how specialized brain areas function and how the brain can adapt.
The Power of Suggestion
placebo effect. The power of suggestion can create real physical healing. A fake MRI machine, combined with belief and expectation, helped children with eczema, migraines, and ADHD improve their symptoms.
How to Make a Hero
Heroes can be made. Heroes can be made, not just born. Training can increase heroic action, but personality and background play a significant role. It's about taking action, even small steps, at personal risk.
Your Brain on Tech
3D video games improve spatial memory. Playing 3D video games can improve spatial memory and even change the shape of your hippocampus. Ten days of gaming improved maze navigation and memory recall by 30% compared to a control group.
Truth Serums and False Confessions
False confessions are common. Truth serums don't work reliably, often causing fabricated memories. Police interrogation techniques like 'fear-then-relief' can elicit false confessions. Brain-wave lie detection (P300 test) shows promise but faces ethical hurdles.
