The Wisdom Audit, part 9 of 9. Seven audit posts and twenty sayings come down to one scoreboard and a protocol you can run yourself.
Across the last seven posts I’ve been running famous sayings against published research. The goal was never contrarianism; being reflexively against proverbs is just as lazy as being reflexively for them. The point was narrower: these sayings are load-bearing. People make career, money, relationship, and health decisions on their authority, and almost nobody has checked their references.
Now the references are checked. Here’s everything on one page.
The scoreboard

| Practice makes perfect | 1550s | England | Proverb tradition | Fails |
| No pain, no gain | 2nd century; 1982 | Judea; US | Ben Hei Hei; Jane Fonda | Fails |
| Curiosity killed the cat | 1598 as “care”; 1868 as “curiosity” | England | Jonson, mutated | Fails |
| Opposites attract | 1950s formalization | US | Robert Winch | Fails |
The final tally across 21 entries comes to 4 holds, 1 mostly holds, 5 conditional, 6 split, and 5 fails. Roughly half of inherited wisdom survives contact with the data, which is exactly the hit rate that makes a saying dangerous: it is often enough right to earn trust, and often enough wrong to spend it badly.
Finding one: the corpus hedges
Three direct contradiction pairs showed up in just these twenty sayings. Leap contradicts hesitate, bold contradicts safe, and birds of a feather contradicts opposites attract. Every proverb has a counterproverb.
This is the structural problem with folk wisdom, and it’s worth stating precisely: a body of advice that asserts both directions can never be wrong, and therefore can never be informative. Whatever happened to you, a saying predicted it, and the survivors quote the one that fit. Each saying is testable. The corpus is not. It functions less like a knowledge base and more like a horoscope with better production values.
The practical implication is simple: any time you hear a proverb deployed as an argument, ask what the counterproverb is. If one exists, the proverb was never evidence. It was a vibe with seniority. (This is an observation about these twenty sayings, which I tested. I make no claim about all proverbs everywhere; that would take a far bigger sample than mine.)
Finding two: transmission distorts, in one direction
This sample contained three documented mutations.
- Care killed the cat became curiosity killed the cat between 1598 and 1868. A warning about anxiety became a warning against inquiry, the one trait the memory and learning research says to cultivate.
- An ad slogan acquired a fake Chinese pedigree. Fred Barnard coined “one look is worth a thousand words” to sell advertising space in 1921, and by 1927 had inflated it to ten thousand and labeled it a Chinese proverb, because he understood that provenance sells.
- Two narrow 1967 lab studies became a universal law of communication. Mehrabian’s single-word experiments turned into “93 percent of communication is nonverbal,” a claim the author himself disowns.
The direction is consistent: the version that survives is the more repeatable one, not the more accurate one. Sayings are optimized by retelling, and retelling selects for punch. Accuracy doesn’t compound. Catchiness does.
The audit protocol
Twenty sayings was enough to extract the method. Here are five questions, in order, for the next piece of inherited advice that reaches you.
1. Who said it, and what were they selling? Barnard was selling ad space. Fonda was selling workout tapes. Lance was selling less government. The anonymous French peasants behind “Rome wasn’t built in a day” were selling nothing, and theirs passed clean. Provenance isn’t proof, but a sales motive is a flag.
2. Is it description or prescription? In this sample, sayings that describe how the world behaves (people pair by similarity, projects take a decade, plans run late) aged far better than sayings that prescribe how you should behave (practice more, endure pain, will harder). Description gets tested against reality every day. Prescription gets repeated in locker rooms.
3. Does a counterproverb exist? If yes, neither one is evidence. Find the variable that decides between them; it’s usually a single variable such as reversibility, downside, or competence parity.
4. Operationalize it. “Practice makes perfect” is unfalsifiable. “Deliberate practice explains most of the variance in expert performance” is falsifiable, and false. If a saying can’t be rewritten as a measurable claim, it isn’t advice. It’s mood.
5. Find the base rate before the anecdote. The base rate is how often the outcome actually happens across everyone who tried, not just the people you heard about. Every saying survives on its highlight reel. The chickens data, the founder returns data, and the IPO age data all say the same thing: the denominator is where the truth lives, and sayings never mention the denominator.
Closing the audit
I started this series because I kept catching inherited one-liners running as silent policy in my own decisions, and I wanted to know which ones deserved the job. The answer turned out to be about half, and rarely the loudest ones.
The ones that survived tend to be old, anonymous, descriptive, and unglamorous. The ones that failed tend to be motivational, monetized, and catchier than their evidence. Your inheritance of advice arrived unaudited. Twenty entries are now checked, and the protocol is above for the rest.
The next time a saying tells you what to do, ask it for its sources. It’s remarkable how few of them have any.
