Genuine, but From the Wrong Book: Keynes on the Long Run

In the long run we are all dead is a real Keynes quotation, so it belongs in the genuine column — with one correction. It is from A Tract on Monetary Reform (1923), not from The General Theory of Employment, Interest and Money (1936), which is where it is most often placed. The misattribution matters because the two books are doing different things: the 1923 Tract is about monetary policy and the folly of waiting passively for prices to adjust, and the line is a jab at economists who offer only the promise that the storm will eventually pass. Detached from that setting, the sentence is frequently misread as Keynes dismissing the future or endorsing short-term recklessness, which reverses his meaning. Genuine quotation, correct author, wrong source, and a distorted interpretation — all in one very famous line.

Fabricated: Einstein and Compound Interest

The line that compound interest is the eighth wonder of the world — sometimes extended with he who understands it, earns it; he who doesn't, pays it — is routinely credited to Albert Einstein. There is no reliable source for it. It does not appear in Einstein's published writings, letters or documented remarks, and quotation researchers have traced its attachment to his name only to the late twentieth century, decades after his death in 1955. Similar versions have at various times been pinned to Baron Rothschild and to Benjamin Franklin, with no better evidence. The mathematics of compound growth is real and important, but the memorable maxim about it is a modern invention that borrowed Einstein's authority. Treat any version of this line attributed to Einstein as fabricated unless someone can produce an actual source, which no one has.

Real, but Not Who You Think: 'It's the Economy, Stupid'

It's the economy, stupid is a genuine phrase from Bill Clinton's 1992 presidential campaign, but it was not said by Clinton. It was written by James Carville, the campaign's chief strategist, as one of three points he posted on a sign at campaign headquarters in Little Rock to keep staff focused on their central message; the trio also included a note about change versus more of the same. It was an internal discipline device, never a public Clinton slogan, and the version that circulates has been smoothed from Carville's original wording. The common shorthand that credits the line to Clinton himself compresses a strategist's staff memo into a candidate's quotation — a textbook case of a phrase drifting toward the most famous name attached to the event that made it famous.

Popularised, Not Coined: 'No Such Thing as a Free Lunch'

There's no such thing as a free lunch is real and is genuinely associated with Milton Friedman, who used it as the title of a 1975 book and made it a slogan for opportunity cost. But he did not coin it. The phrase comes from the nineteenth- and early-twentieth-century American saloon practice of offering free food to paying drinkers, with the food's cost built into the drink prices — so the lunch was never actually free. It appears in print well before Friedman's career and features in Robert Heinlein's 1966 science-fiction novel The Moon Is a Harsh Mistress. The accurate credit is that Friedman popularised it for economics; the frequent claim that he invented it is one of the discipline's most repeated attribution errors, and Friedman himself made no such claim.
