Mindtrix Writing that takes a full page, not a card
Mindtrix gives you one idea a minute. These are the ideas that need longer than a minute: the evidence behind them, the parts that are contested, and what to do differently on Monday.
Every topic in the Mindtrix library is built from short cards, because that is what fits into a morning. But a card can only carry a claim. It can't carry the argument around the claim: how strong the evidence is, who disagrees, what the finding does not imply, and what would have to be true for the whole thing to be wrong.
Field Notes is where that part lives. Each piece is a single topic followed all the way down, usually between one and two thousand words, with the actual studies and books at the bottom so you can decide for yourself whether we represented them fairly.
Growth mindset isn't positive thinking
What Dweck's research actually showed, why "yet" became a slogan, and the meta-analysis that shrank the effect without killing the idea.
Why your brain resists evidence that contradicts you
Motivated reasoning is not stupidity. It is what thinking looks like when a conclusion is part of who you are, and there is one move that reliably loosens it.
The money skills nobody teaches you
Compounding, fees, and the two behavioral habits that separate people who build wealth from people who earn well and keep nothing.
You can't repay sleep debt on the weekend
Six hours a night doesn't feel bad — that's the finding. What controlled sleep-restriction studies showed about accumulation, and how little one long night restores.
Habits don't take 21 days — they take a context
The 21-day rule is a misquote from a 1960 book about plastic surgery. What a 96-person study found, and why the cue matters more than repetition.
How to read a study without being fooled
What the replication crisis actually measured, why small samples exaggerate, and how a "fifty percent higher risk" can mean three in a hundred instead of two.
Why prices never come back down
Inflation is a rate, not a level. Sticky wages, shrinkflation, money illusion, and the reason central banks aim at two percent instead of zero.
Stoicism isn't about not feeling things
The dichotomy of control is not indifference. What Epictetus and Seneca actually claimed, where the gym-mirror version goes wrong, and what the evidence supports.
How these are written
One claim per section, stated plainly, then the reasoning. Where a finding has been replicated weakly or debated, we say so in the text rather than in a footnote. Where we give a number, it comes from a named source you can open yourself.
