How was Einstein's IQ rated?

// Albert Einstein - IQ //

There Einstein never one during his lifetime IQ After completing the test, experts subsequently estimated his IQ to be around 160 to 180.

The physicist Albert Einstein (1879 - 1955) is known for the development of the theory of relativity, which many in school have heard of. He is considered one of the greatest physicists of all time. The exact IQ (= Intelligence quotient) this man is unknown as he never took the test in his lifetime.

IQ estimate

A normal intelligence quotient (IQ) is between 85 and 115 (on the Stanford-Binet scale). Only about 1% of the people in the world have an IQ of 135 or more.
In 1926 the psychologist Dr. Catherine Morris Cox - supported by Dr. Lewis M. Terman, Dr. Florence L. Goodenaugh and Dr. Kate Gordon - a study of "the greatest men and women" who lived between 1450 and 1850 to estimate what their IQ might have been. The resulting IQs were based largely on the level of cleverness and intelligence each individual displayed before they reached the age of 17.

By the way: The contemporary writer Marilyn vos Savant (* 1946) has the highest IQ ever measured with 228.

Einstein's intelligence

Einstein was one of the greatest minds of all time, and the questions on an IQ test are trivial compared to the problems he solved, one of which, general relativity, was probably the most extraordinary cognitive leap in human history.
He wasn't a withdrawn, contemplative genius either - contemporary reports say his mind was agile and quick, and that he often solved problems on the spot.
However, it is still controversial whether the conventional IQ tests are an appropriate measure of intelligence at all.
Eugene Wigner (1902-1995) a Hungarian-American physicist and Nobel Prize winner, once said:

“I've known a lot of intelligent people in my life. I knew Planck, von Laue and Heisenberg. Paul Dirac was my brother-in-law; Leo Szilard and Edward Teller were among my closest friends; and Albert Einstein was a good friend too. But none of them had such a quick and sharp mind as John von Neumann. I have often noticed this in the presence of these men, and no one ever contradicted me. "

Von Neumann had all the characteristics that we associate with an extraordinary IQ: he could multiply 8-digit numbers in his head, mastered ancient Greek at the age of three, etc.
But Einstein's mind was different. He seemed to be walking in a field beyond what the rest of us inhabit. Einstein had a unique, penetrating, and original mind (and, if the autopsy results are to be believed, a structurally unusual brain). See also what we know about Albert Einstein's brain.
