Not having a gi (grips and friction), plays even a bigger role. But also Olympic judo is very different from old school judo, unfortunately becoming a sport It becomes all about optimizing for rules (relishing grips, no below body attacks, fall on your stomach when in trouble), not self-defense or fighting. Brazilian Jiu-Jitsu is also heading that way.
Nassim Taleb has done good work on this. "Cognitive Biases" are adaptive, rational heuristics or shortcuts that make sense in real-world conditions—especially under uncertainty, fat-tailed risks (where rare events dominate), survival pressures, and constraints like limited information or skin in the game.
Comparing it to GDP is misleading, it's the wrong denominator (GDP measures transactions, which have increased at higher rate but have nothing to do with base layer production input). Absolute global oil consumption has tripled (~32M → 102M bpd). Much of the efficiency gained is from deindustrialization, offshoring heavy industry, and the shift to low-energy services/tech — as part of GDP. Oil is now locked into the hardest-to-substitute uses transport, aviation, shipping, petrochemicals/plastics. Efficiency gains are there but oil is even more important today. Hypothetical: What would today's global economy and 8.2 billion people do if oil production suddenly returned to 1965 levels of just 32 million barrels per day?
@charliebilello Complexity leads to corruption. Harder to cheat in a simple system. On the bright side AI will completely change this useless industry.
@ihtesham2005 Universal memory advantage of the Zeigarnik effect failed to replicate, but the behavioral drive it creates—and its appearance under highly specific conditions—has held up (Ovsiankina Effect).
If we assume the point of investing is ultimately to improve your quality of life and the quality of life of those you most care about, investments that consistently add stress over long periods of time probably don’t make sense.
Money is traded for things or experiences that catalyze certain feelings. If your investments are generating the opposite spectrum of feelings, it might be time to reassess. It’s easy to miss the forest for the trees.
Money is a means, not an end.
And in the end, most things matter very, very little.
Do what helps you sleep at night and wake up with a low heart rate.
To me, those are the hallmarks of a world-class investor who gets the big picture.
