If the facts don't fit the theory, change the facts.

The earliest published attribution of this quote to Einstein found on google books is the 1991 book The Art of Computer Systems Performance Analysis by Raj Jain (p. 507), but no source to Einstein's original writings is given and the quote itself is older; for example New Guard: Volume 5, Issue 3 from 1961 says on p. 312 "Someone once said that if the facts do not fit the theory, then the facts must be changed", while Product engineering: Volume 29, Issues 9-12 from 1958 gives the slight variant on p. 9 "There is an age-old adage, 'If the facts don't fit the theory, change the theory.' But too often it's easier to keep the theory and change the facts." These quotes are themselves probably variants of an even earlier saying which used the phrasing "so much the worse for the facts", many examples of which can be seen in this search; for example, the 1851 American Whig Review, Volumes 13-14 says on p. 488 "However, Mr. Newhall may possibly have been of that causist's opinion, who, when told that the facts of the matter did not bear out his hypothesis, said 'So much the worse for the facts.'" The German idealist philosopher Johann Gottlieb Fichte circa 1800 did say "If theory conflicts with the facts, so much the worse for the facts." The Hungarian Marxist Georg Lukacs in his "Tactics and Ethics" (1923) echoed the same quotation.Albert Einstein

Those who cavalierly reject the Theory of Evolution as not being adequately supported by facts seem to forget that their own theory is supported by no facts at all.
Herbert Spencer
What are the facts? Again and again and again — what are the facts? Shun wishful thinking, ignore divine revelation, forget what "the stars foretell," avoid opinion, care not what the neighbors think, never mind the unguessable "verdict of history" — what are the facts, and to how many decimal places? You pilot always into an unknown future; facts are your single clue. Get the facts!
Robert A. Heinlein
Now, what I want is, Facts. Teach these boys and girls nothing but Facts. Facts alone are wanted in life. Plant nothing else, and root out everything else. You can only form the minds of reasoning animals upon Facts: nothing else will ever be of any service to them. This is the principle on which I bring up my own children, and this is the principle on which I bring up these children. Stick to Facts, sir!
Charles Dickens
Prentice: It's a fascinating theory, sir, and cleverly put together. Does it tie in with known facts?
Rance: That need not cause us undue anxiety. Civilizations have been founded and maintained on theories which refused to obey facts.Joe Orton
The day of manipulating a jury is absolutely gone, if there ever was such a day. Cases are won through preparation, dragging the facts into the courtroom. The lawyer excavates the facts, and the more he digs, the more certain is he to win; and then he can pound upon the facts and the emotional appeal-that's the way of persuasion. But to play clever with a jury when you don't have the facts leaves them cold. They resent it.
