The 10-Minute Mood Intervention: A specific writing practice, performed for just 5 to 10 minutes per day over 8 weeks, produces reductions in depressive symptoms that — in head-to-head trials — match or exceed the effects of starting-dose SSRIs. The practice has no side effects, costs nothing, requires no prescription, and shows effects that persist … Read more
The Personality Reading That Fits Everyone: If you give an entire room of people the same paragraph of vague personality description and ask each person to rate how accurately it describes them specifically, the average rating will be around 4.3 out of 5. This works whether the room contains skeptics, scientists, or astrology enthusiasts. The … Read more
The Two Stresses, and Why They Do Opposite Things: One of the most counterintuitive findings in modern neuroscience is that brief, acute stress — the kind that lasts minutes to hours — actually improves certain forms of memory and cognitive performance, while chronic stress sustained over weeks or months produces the opposite effect. The same … Read more
The Pace That Predicts Your Future: The speed at which an older adult walks across a hospital corridor — measured in nothing more sophisticated than meters per second — predicts their mortality risk, cognitive decline trajectory, and 10-year functional outcomes more accurately than most expensive medical tests. The threshold is 1.0 meters per second. Walking … Read more
The Most Profitable Default in the Modern Economy: The single feature responsible for more subscription revenue than any advertising campaign, any product improvement, or any pricing strategy is a small architectural choice present in nearly every consumer software service: the free trial that converts to paid subscription unless the user takes positive action to cancel. … Read more
The Stories You Read Are Lying By Omission: The most consequential statistical error in modern startup culture, in self-help literature, in investment advice, and in nearly every form of success-narrative journalism is not in the data presented. It is in the data that was never collected — the failures, the wash-outs, the businesses that closed … Read more
The Brain That Builds Self-Control Out of Saying No: The neural capacity to refuse, postpone, or override an impulse — the foundation of nearly every long-term personal achievement — is not a personality trait you were born with. It is a specific brain function, anatomically localised, biologically expensive, and measurably strengthened by repeated use. The … Read more
The Time Zone You Live in Twice a Week: Most adults experience the equivalent of a 2-to-3-hour time-zone shift every Friday evening — and an opposite shift every Sunday night. The shifts are not produced by travel. They are produced by the simple act of staying up late and sleeping in on weekends, then returning … Read more
The Nerve You Feed Through Your Mouth: One of the most consequential nerves in the human body — running from the brainstem through the chest and abdomen, governing parasympathetic tone, heart-rate variability, and the basic biology of recovery — is influenced by what you eat in ways modern medicine is still mapping. The nerve is … Read more
The Inheritance That Skips DNA: The children of Holocaust survivors show measurable biological signatures of their parents’ trauma — even though they themselves did not experience the original events, were often born years after liberation, and grew up in stable post-war environments. The signatures appear in stress-hormone profiles, cortisol receptor genes, and downstream metabolic and … Read more
