Albert Einstein? George Bernard Shaw? Stuart Chase? S. I. Hayakawa? Robert Anton Wilson? Minot Judson Savage? Donald Kennedy? Percy Williams Bridgman? Anonymous?

Question for Quote Investigator: We are often admonished to use common sense, but a wit once pointed out the drawback of relying on this simple guideline:
Common sense is what tells you the world is flat.
This expression has been attributed to physicist Albert Einstein, playwright George Bernard Shaw, English professor S. I. Hayakawa, economist Stuart Chase, writer Robert Anton Wilson, and others. I am skeptical because I have not seen a solid citation. Would you please explore this topic.
Reply from Quote Investigator: QI has found no substantive evidence supporting the attribution to Albert Enstein who died in 1955. Einstein received credit many years later in 1990.

Below are details for selected citations in chronological order.
In 1866 “The Suburban Magazine” of London, England printed an article without a byline titled “Common Sense” which highlighted the dangers of relying on common sense:1
It must not, however, be forgotten while dwelling on the praises of common sense, that men actuated by its principles, and adhering to its conditions, according to their lights, have been led into grave errors. Such doctrines as, that the sun goes round the earth, and not the earth round the sun—that the world is flat, and similar scientific absurdities, have been maintained by those who, in times past, adhered to what they saw and believed to be true, and denied all assertions to the contrary.
In 1872 “The Morning Advertiser” of London printed the following passage without a byline:2
Common sense, in this uncommon sense, convinces us that the world is flat, and that the sun, moon, and stars are our satellites, which get up in the East and go down again In the West every twenty-four hours; and an infinite deal more stuff of this kind which Science has demonstrated to be false and absurd.
In 1884 Unitarian minister Minot Judson Savage published the book “Beliefs About Man” which contained a concise version of the saying:3
… as Huxley has said, common-sense is only another name for “common ignorance.” It needs to be supplemented, now and again, by a little sense that is not so common. Common-sense teaches us, even to-day, that the world is flat. It taught that for thousands of years, and it took a great while to argue into the common-sense of the crowd the belief which is now established beyond question.
In 1923 Dr. Harry Roberts published an article in “The Western Daily Press” of Bristol, England which contained the following:4
Common sense says the world is flat: science says it is spherical. Common sense came to the natural conclusion that the sun moved round the earth: science found that the earth moved round the sun; and got its ambassador executed for saying so.
In 1924 George Bernard Shaw published the play “Saint Joan”, and he wrote the following in the preface. Shaw’s comments did not match the saying under examination, but they were thematically related:5
In the Middle Ages people believed that the earth was flat, for which they had at least the evidence of their senses: we believe it to be round, not because as many as one per cent of us could give the physical reasons for so quaint a belief, but because modern science has convinced us that nothing that is obvious is true, and that everything that is magical, improbable, extraordinary, gigantic, microscopic, heartless, or outrageous is scientific.
In 1940 Edward Kasner and James Newman published “Mathematics and the Imagination” which contained the following:6
Good common sense makes it plain that the earth is flat and stands still, that the Chinese and the Antipodeans walk about suspended by their feet like chandeliers …
In 1948 Stuart Chase published “The Proper Study of Mankind: An Inquiry into the Science of Human Relations” which contained the following:7
Common sense tells us that the world is flat, that the sun goes around the earth, that heavy bodies always fall faster than light bodies. The practical man, that paragon of common sense, was once defined by Disraeli as “one who repeats the errors of his forefathers.”
In 1949 S. I. Hayakawa published “Language in Thought and Action”, and Hayakawa credited a version of the saying to Stuart Chase:8
Citizens of a modern society need, therefore, more than ordinary “common sense” — which was recently defined by Stuart Chase as that which tells you that the world is flat. They need to be scientifically aware of the powers and limitations of symbols, especially words, if they are to guard against being driven into complete bewilderment by the complexity of their semantic environment.
In 1957 K. C. Ingram published “Talk That Gets Results: Key To Success and Harmony with Others”. Ingram credited the saying to Chase:9
If scientists did not think of the novel and the unusual we would have few of the great inventions that have revolutionized our everyday life during recent times. As Stuart Chase noted, ‘Common sense is what tells you the world is flat.’ Franklin’s idea about electricity was screwball.
In 1962 Robert T. Oliver published “The Healthy Mind in Communion and Communication” which credited another version of the saying to Chase:10
STUART CHASE has described common sense as the faculty which “tells us the world is flat.”
In 1966 Robert A Golde published “Thinking With Figures in Business” which provided an anonymous attribution for the saying:11
As some wag noted, “Common sense is what tells you the world is flat!” Furthermore, each discipline seems to develop its own kind of common sense. What is obvious to a doctor is not at all obvious to a businessman, and what is perfectly clear to a businessman may be incomprehensible to an engineer.
In 1974 the periodical “Green Egg” printed a review of the book “Principia Discordia”. The review reprinted several sayings from the book:12
It contains many inspirational and uplifting epigrams such as: “Bullshit makes the flowers grow and that’s beautiful.” “When in doubt, fuck it. When not in doubt…get in doubt.” “Common sense is what tells you that the world is flat.” “It is my firm belief that it is a mistake to hold firm beliefs.”
In 1979 “The Sacramento Union” of California printed the following which credited the saying to a government official:13
… Food and Drug Administration chief Donald Kennedy warns that even though common sense suggests the tiny chemical traces are harmless, “common sense also tells us that the world is flat.”
In 1990 Robert Anton Wilson published “Quantum Psychology: How Brain Software Programs You and Your World”. Wilson attributed the saying to Einstein:14
That’s why Einstein had to remind us, “Common sense tells us the earth is flat.”
In 1997 Adam Przeworski and Fernando Limongi published an article in the journal “World Politics: A Quarterly Journal of International Relations”, and the authors attributed the saying to George Bernard Shaw:15
Yet common sense would indicate that in order to strengthen democracy we should strengthen democracy, not support dictatorships. And, even if G. B. Shaw warned that “common sense is that which tells us that the world is flat,” the lesson of our analysis is that this time it is the best guide.
In 1998 Stephen Booth published “Precious Nonsense”, and he attributed the saying to physicist Percy Williams Bridgman:16
Common sense is wrong. After all, as the physicist Percy Bridgman observed more than half a century ago, common sense is something that tells us the world is flat.
In 2000 Vincent Fu published the compilation “Quote This!!!” which contained the following entry:17
Common sense is what tells you that the world is flat.
-Anonymous
In conclusion, the saying evolved over time. The originator remains anonymous. Different phrasings have distinct nuances. Minot Judson Savage employed a concise instance in 1884.
The attribution to Albert Enstein is unsupported. Einstein received credit in 1990 which was many years after his death. The attribution to George Bernard Shaw is unsupported. Shaw received credit in 1997 which was many years after his death. Also, Shaw wrote a thematically related remark in 1924. Stuart Chase employed an instance in 1948, but the saying was already in circulation.
