Ever wondered what the highest possible IQ is? The answer is 250! Do you think it is a big deal?
Then here are some quick facts: if you get a score of 110 in an IQ test, it is considered to be above average intelligence.
Albert Einstein is estimated to have an IQ between the range of 160-190 and Stephen Hawking is said to have 160, though none took the test.
What Is IQ?
In 1916, Lewis Madison Terman, an American psychologist, developed the intelligence quotient or IQ. He was employed by the United States Army and the first ever mass IQ test was conducted during World War I. According to Terman’s scale, people who score under 70 are “definite feeble-minded”; between 70 and 79, possibly have “borderline deficiency”; between 80 and 89 are considered dull. The average score is between 90 and 109, which is considered to be “normal”. A score between 110 and 119 shows superior intelligence; between 120 and 140 shows extreme intelligence; and a score over 140 is a sign of a true genius.

The mean of the normal distribution was arbitrarily placed at 100 when the test was conducted. This basically means if you score lower than 100, you are below average and above 100 the opposite. The standard deviation is taken to be 15, which makes IQ of 200 impossible. The numbers below hence are not accurate.
