Last week I confidently cited Mark Twain on historyâs tendency to rhyme. The line felt perfect. Short and profound, very Twain.
One problem: he never said it.
The quote appeared in 1970, sixty years after his death.
The irony? The misquote captured the truth better than Twainâs actual words.
Take the business worldâs favorite line:
âWhat gets measured gets managed.â
Peter Drucker said that, right?
No!
The phrase comes from journalist Simon Caulkin, who was summarizing a 1956 research paper by organizational researcher V.F. Ridgway. Ridgwayâs paper warned that obsessing over metrics could mess up how organizations actually work.
The full quote (which nobody remembers) is:
âWhat gets measured gets managed, even when itâs pointless to measure and manage it, and even if it harms the purpose of the organization.â
We kept the catchy part, threw out the warning, and stuck a famous name on it. A caution against metric fixation became its biggest cheerleader.
Same thing happens with investment advice. We remember the catchy version, forget the caveats.
Misquotes survive because they hold truths, even when the attribution is fiction. History does rhyme across cycles. Metrics do drive behavior. Theyâre wrong on attribution but right on insight. Thatâs why we keep using them despite knowing better.
đŹ What misquote are you still using anyway?
