BACKGROUND · REMBRANDT, ARISTOTLE WITH A BUST OF HOMER, 1653 · THE MET, OPEN ACCESS

THE SHORT VERSION

  1. Fifteen famous lines checked. Six belong to somebody else, two are genuine, and six are real but trimmed or misquoted, including three well-known lines from film and fiction. One is an origin story with no source.
  2. There is no evidence Einstein said insanity is doing the same thing and expecting different results. The earliest versions found so far come from addiction-recovery groups in 1981, 26 years after he died.
  3. "Do one thing every day that scares you" is from a 1997 newspaper column by Mary Schmich of the Chicago Tribune. She has written that she has seen no evidence Eleanor Roosevelt said it.
  4. Sherlock Holmes never says "Elementary, my dear Watson" in Conan Doyle's stories, and nobody in Casablanca says "Play it again, Sam."

What we found

Our reading of the evidence on each of the 15 lines, with where it comes from. Open any row, look at the source, and make up your own mind.

Myth"Insanity is doing the same thing over and over and expecting different results" — Einstein

There is no substantive evidence that Einstein said it, and The Ultimate Quotable Einstein (Princeton University Press) lists it among lines misattributed to him. The earliest strong match Quote Investigator found is from October 1981: a Knoxville, Tennessee newspaper report of an Al-Anon meeting, where an attendee says "Insanity is doing the same thing over and over again and expecting different results." A Narcotics Anonymous pamphlet printed in November 1981 has a close version. By 1990 the line was being credited to Einstein, who died in 1955. In its first known setting it was about recovery, not physics.

SOURCE Quote Investigator, "Insanity Is Doing the Same Thing Over and Over Again…"

Myth"Everybody is a genius. But if you judge a fish by its ability to climb a tree…" — Einstein

No substantive evidence that Einstein said it, and it is not in The Ultimate Quotable Einstein. The earliest close match Quote Investigator found is in a 2004 self-help book, decades after Einstein died in 1955. The idea behind it is much older: An Educational Allegory, published in the Journal of Education in 1898 under the pen name "Aesop, Jr." and later identified as the work of the physicist Amos E. Dolbear, imagines a school where no animal could graduate unless it could "climb, swim, run, and fly at a certain prescribed rate".

SOURCE Quote Investigator, "Everybody is a Genius…", quoting Dolbear's An Educational Allegory (1898).

Myth"Do one thing every day that scares you" — Eleanor Roosevelt

It comes from Mary Schmich's column in the Chicago Tribune, 1 June 1997, the piece later circulated as Wear Sunscreen. In 2012 Schmich wrote that the line "is now widely attributed to Eleanor Roosevelt, though I have yet to see any evidence that she ever said it and I don't believe she did." What Roosevelt did write, in You Learn by Living (1960), is close in spirit: "You must do the thing you think you cannot do."

SOURCE Quote Investigator, "Do One Thing Every Day That Scares You", citing the Chicago Tribune (1 June 1997 and 2012) and You Learn by Living (1960).

Myth"Well-behaved women seldom make history" — Eleanor Roosevelt, or Marilyn Monroe

It is the historian Laurel Thatcher Ulrich, in her 1976 article "Vertuous Women Found": New England Ministerial Literature, 1668–1735, in American Quarterly. It closes her opening paragraph about pious women in early New England sermons: "Hoping for an eternal crown, they never asked to be remembered on earth. And they haven't been. Well-behaved women seldom make history." Her aim, she has written, was "neither to celebrate nor to lament their piety but to give them a history." Her 2007 book of the same title, she says, meant fewer people attributed the line to Eleanor Roosevelt or Marilyn Monroe.

SOURCE Laurel Thatcher Ulrich, "Why Well-Behaved Women Seldom Make History", BYU Studies 59:3.

Myth"Be yourself; everyone else is already taken" — Oscar Wilde

No substantive evidence that Wilde said it, and it is not in Ralph Keyes's collection The Wit & Wisdom of Oscar Wilde. The first strong match Quote Investigator found is an unattributed Usenet post from December 1999, almost a century after Wilde died in 1900. Wilde did write on the theme, differently, in De Profundis (published 1905): "Most people are other people."

SOURCE Quote Investigator, "Be Yourself. Everyone Else Is Already Taken".

Myth"If I had asked people what they wanted, they would have said faster horses" — Henry Ford

The Henry Ford museum says it "has never been satisfactorily traced to Henry Ford" and only begins to appear in the early 21st century. The earliest link to Ford that Quote Investigator found is a 1999 cruise-industry magazine, where a designer speculates about what Ford's customers would have wanted; the earliest direct attribution is a 2001 letter to Marketing Week. Ford died in 1947. We also searched his memoir My Life and Work on Project Gutenberg and found no "faster horse".

SOURCE The Henry Ford, "Henry Ford's Quotations"; Quote Investigator; My Life and Work (Project Gutenberg #7213), searched.

True"Genius is one percent inspiration and ninety-nine percent perspiration" — Edison

Fair to credit to him, though the numbers moved. In April 1898 The Ladies' Home Journal quoted him: "Two per cent. is genius and ninety-eight per cent. is hard work." The 1 and 99 version was credited to him in an Idaho newspaper in 1901, while Scientific American printed a 2 and 98 version on 27 December 1902. In 1932 a man who had worked in his laboratory quoted Edison referring to "what I have said, 'Genius is one per cent inspiration, ninety-nine per cent perspiration.'" The idea that genius is mostly perspiration was already in circulation in 1892.

SOURCE Quote Investigator, "Genius Is One Percent Inspiration…", citing The Ladies' Home Journal (1898), Scientific American (27 Dec 1902) and Harper's Magazine (1932).

True"The only thing we have to fear is fear itself" — Franklin D. Roosevelt

Real, and dated. It is from his first inaugural address, 4 March 1933. The whole sentence: "So, first of all, let me assert my firm belief that the only thing we have to fear is fear itself—nameless, unreasoning, unjustified terror which paralyzes needed efforts to convert retreat into advance."

SOURCE Franklin D. Roosevelt, Inaugural Address, 4 March 1933 (American Presidency Project).

Partly true"Blood, sweat and tears" — Churchill

He said it with a fourth word, in a different order. Churchill became Prime Minister on 10 May 1940. On 13 May 1940 he told his Cabinet, and then the House of Commons: "I have nothing to offer but blood, toil, tears and sweat." The shorter trio was already in use (a 1939 magazine article has "blood, sweat, and tears"), and in 1941 his American publisher chose Blood, Sweat and Tears as the title of his first volume of war speeches.

SOURCE International Churchill Society, "Blood, Toil, Tears and Sweat"; Hillsdale College Churchill Project (2018).

Partly true"Elementary, my dear Watson" — Sherlock Holmes

Both halves are Holmes's, but never together in Conan Doyle. We searched the four novels and five story collections on Project Gutenberg: Holmes says "Elementary," on its own once, in The Crooked Man, and "my dear Watson" dozens of times, but the two never meet. Quote Investigator found the exact phrase in a London newspaper in 1908, and it closes the 1929 film The Return of Sherlock Holmes.

SOURCE Conan Doyle's Holmes novels and stories (Project Gutenberg), searched; Quote Investigator, "Elementary, My Dear Watson".

Partly true"Play it again, Sam" — Casablanca

Nobody in the film says it. Ilsa says "Play it once, Sam. For old times' sake." and then "Play it, Sam. Play 'As Time Goes By.'" Rick later says "You played it for her, you can play it for me!" and "If she can stand it, I can! Play it!" Woody Allen used the misquote as the title of his 1969 Broadway play.

SOURCE Casablanca (1942): AFI's 100 Movie Quotes; Wikiquote; The Phrase Finder.

Partly true"Luke, I am your father" — The Empire Strikes Back

The line in the film is "No, I am your father." In a script copy online, Luke has just said "He told me enough! It was you who killed him." The shared version drops the "No", which only makes sense after Luke's line, and adds his name.

SOURCE The Empire Strikes Back (1980): ACMI; a script copy online (IMSDb).

Partly true"Money is the root of all evil" — the Bible

Two missing words change the meaning. 1 Timothy 6:10 in the King James Version reads: "For the love of money is the root of all evil: which while some coveted after, they have erred from the faith, and pierced themselves through with many sorrows." The verse is about loving money, not about money itself.

SOURCE 1 Timothy 6:10 (King James Version).

Partly true"Pride comes before a fall" — the Bible

Close, and trimmed. Proverbs 16:18 reads: "Pride goeth before destruction, and an haughty spirit before a fall." The saying fuses the two halves of the verse into one.

SOURCE Proverbs 16:18 (King James Version).

Myth"Blood is thicker than water" originally meant the opposite — the blood of the covenant beats the water of the womb

The reversal is the part with no source, not the proverb. The "covenant" reading appears in books from the 1990s and 2000s that cite no source for it. The saying itself is recorded long before those books. A sermon by the London minister William Jenkyn, printed in the early 1650s, introduces it as something everyone says: "Blood is thicker (we say) then water", before turning it to the blood of Christ, which he says should count for more than "a watery relation of nature". Scott uses it in the family sense: in Guy Mannering (1815) a character says "Weel, blude's thicker than water; she's welcome to the cheeses and the hams just the same." A related German saying, that kin-blood is not spoiled by water, appears in the beast epic Reinhart Fuchs of about 1180.

SOURCE Wikipedia, "Blood is thicker than water" (citing Jenkyn, 1653 edition, and the Oxford Dictionary of Proverbs); Scott, Guy Mannering (1815).

THE ARTICLE · 4 MIN

The first part of this series checked twenty-two quotations, from ancient writers to modern films. This one is mostly modern: scientists, presidents, businessmen and films, plus two lines of scripture.

Six of these fifteen lines belong to somebody else. Two are genuine. Six are real but have been trimmed, reordered or misquoted, including three well-known lines from film and fiction. And one is an origin story that has no source. Each line has its own verdict and source in the table; the sections below are about the patterns.

The name gets upgraded

The pattern from part one shows up again. A line starts somewhere less famous (a recovery-group meeting, a newspaper column, an online post, a journal article) and after years of repetition it picks up a famous name.

On this page, lines about how to think drift to Einstein, lines about courage and about women making history drift to Eleanor Roosevelt, a witty line about being yourself drifts to Oscar Wilde, and a line about innovation drifts to Henry Ford. An article on the Henry Ford museum’s website says he “has become a patron saint of the entrepreneur, a Paul Bunyan of the business world.” In two of these cases, the person who really wrote the line can still be named.

The Mary Schmich column is a clear example. Do one thing every day that scares you appeared in her Chicago Tribune column of 1 June 1997. By August 1997 the column was circulating without her name, retitled “Wear Sunscreen” and wrongly described as a graduation speech by Kurt Vonnegut. In 1999 it became the spoken-word song “Everybody’s Free (To Wear Sunscreen)”, which credited her. The line was later attributed to Eleanor Roosevelt, and in 2012 Schmich wrote that she had seen no evidence Roosevelt said it.

The film lines

The three screen and fiction lines follow a different pattern: the misquote carries its own context.

No, I am your father only makes sense after Luke’s line, and the shared version puts Luke’s name where the “No” was. Play it, Sam needs the song named. Elementary and my dear Watson are both Holmes’s words in Conan Doyle, just never in the same breath. In our reading, each misquote works on its own, which makes it easier to share, and in time it is the version people remember.

The quiet edits

The scriptural and political lines were not misattributed. They were trimmed, and the trim changed them.

The love of money is the root of all evil becomes money is the root of all evil, which is a different claim. Blood, toil, tears and sweat loses the toil. Pride goeth before destruction, and an haughty spirit before a fall is squeezed into one clause. In each case the missing words are the ones that made the sentence longer, and in the verse from Timothy they are the words that carried the meaning.

How to check one yourself

  • If it sounds exactly like the famous person, it is worth a second look. Several lines on this page ended up with a famous name that seemed to fit.
  • Look for the earliest version, and its date. A line first found in print in 2004 is hard to pin on someone who died in 1955.
  • For a film or book line, check the script or the text. Many are easy to search, and they usually settle it in a minute.
  • For scripture, read the whole verse. The shared version is often missing part of it.
  • Check the story about the saying, too. An origin story can need a source as much as the quotation does.
