Research on affective memory shows that positive experiences don't just feel better — they're encoded more durably than negative ones.
Fading Affect Bias is a cognitive pattern where negative emotions attached to memories decay faster than positive ones.
Two dietary levers consistently linked to elevated IGF-1 are red meat consumption and dietary calcium intake, with calcium especially relevant in a bone-tissue context.
Red meat, dairy products, and dietary calcium are all associated with higher circulating IGF-1 levels.
The Facial Action Coding System provides a systematic mapping between discrete facial muscle activations and emotional expressions, developed by Paul Ekman.
Robert Greene notes that extroverts generally outnumber introverts in the population, making outward-facing energy the statistical default in most rooms.
Investors routinely misjudge what their money managers will do because they model the manager's incentives as if they were the investor's incentives. They are not.
When behavior is wrong, do not lecture the people — redesign the structure. Federal Express discovered its crews were falsifying shipment paperwork; the cause was a shift-pay scheme that rewarded behavior orthogonal to the goal.
Notes have a type and a type has a home. Episodic events go to daily notes as raw 'what happened' logs. Semantic knowledge gets distilled into atomic cards in a Cards/ folder.
Promotion-based memory files feel rigorous but quietly stop working. Recall-count gates never pass, events pile up as logs without ever being distilled, and the file becomes a tomb of unloved entries.
XML's value lies in its ability to represent deeply nested, hierarchical data through matched opening and closing tags.
Because experiential knowledge cannot be packaged in words, a teacher cannot hand it to a student.
Anders Ericsson's deliberate practice research is routinely misquoted as 'just put in the hours.' But hours only count when they carry targeted experiential feedback — naive repetition produces experience without producing experiential
Propositional knowledge — what you can read, hear, or memorize — is real and useful, but it cannot bridge the gap to performance.
Evolutionary radiation is defined simply as an increase in taxonomic diversity — and it directly causes elevated rates of speciation.
Evolutionary radiation — the rapid explosion of new species from a single lineage — is triggered by three mechanisms: specialisation into narrow parameters, colonisation of a new realised niche, and adaptation to new conditions.
The defining feature of the modern condition is a velocity mismatch: cultural and technological change now outruns biological evolution by orders of magnitude.
Evolutionary mismatch names the gap when previously adaptive alleles are no longer favored in a new environment.
Robert Greene argues that progress has not eliminated our ancient emotions or replaced our irrational wiring; it has merely shifted the surface forms they take.
Evolution's true currency is reproduction, not survival. A trait that actively damages your chances of living can still sweep through a population if it boosts mating success.
The word 'authenticity' gets misused as a synonym for expressing feelings or being true to a brand.
Most people chase competition because proven demand feels safe — there are success cases, established metrics, clear customers. But proven demand and saturated supply are two sides of the same coin.
Naval's framework flips the usual logic: competition is not a signal of a good market — it's a signal that you're copying what others are already doing. Copying adds supply to an existing pool, which drives prices toward commodity returns.
Shackleton's reputation isn't built on discovery or speed - it's built on what he could do when everything had already gone wrong.
Although the erector spinae is named for its role in extending the spine, it is also responsible for flexion and lateral flexion.
The erector spinae attaches from the sacrum all the way up to cervical vertebra C2, making it one of the longest continuous muscle groups in the human body.
Enzymes are specialized proteins that function as biological catalysts, accelerating chemical reactions without being consumed in the process.
The existence of the enteric nervous system shows that evolution repeatedly favors semi-autonomous modules that can handle local decisions without round-tripping to a central controller.
The enteric nervous system is a vast network of neurons embedded in the lining of the gastrointestinal tract that controls digestion largely on its own.
People who achieve the most durable success in competitive domains are almost always those who 'would do it for free' — and this isn't sacrifice, it's the mechanism by which results compound.
