Adragon De Mello: IQ 400
In 1988, when Adragon De Mello graduated from the University of California, Santa Cruz, with a degree in computational mathematics at the age of 11, he was the youngest college graduate in the United States (a record he no longer holds).
Notably, the average IQ score falls between 85 and 115. A score above 140, meanwhile, is considered to be genius level.
The lowest IQ score is 0/200, but nobody in recorded history has officially scored 0. Any result below 75 points is an indicator of some form of mental or cognitive impairment.
Abilities change, but IQ scores tend to be very stable. However the intelligence ability is changing during the life, the IQ (intelligence quotient) does not. This measure is defined to have mean of 100 in each age group. So the average IQ e.g. in the age 5 is 100, and the same in the age 50.
The smartest person in the world was Isaac Newton, a true polymath whose brilliance never has been, nor ever will be, surpassed. Isaac Newton made tremendous advances, largely on his own, across many disciplines of physics and mathematics. He revolutionized gravitation, motion, optics, and co-invented calculus.
IQ tests are made to have an average score of 100. Psychologists revise the test every few years in order to maintain 100 as the average. Most people (about 68 percent) have an IQ between 85 and 115. Only a small fraction of people have a very low IQ (below 70) or a very high IQ (above 130).
One of the most well-known online exams available to you is Free-IQTest.net. It has 20 questions that will measure your IQ score accurately. After this test, you have to give your birth date since the test calculates your IQ score based on your age. This way, you may compare yourself to your peers.
In fact, the Chinese-Australian Terence Tao is the person with the highest IQ in the world at present. With an outstanding IQ of 230, Terence Tao was born on July 17, 1975 in Adelaide, Australia.
The average IQ in Australia is 98. Anything between 90 and 110 is average and anything over 140 is classed as genius Whether we can improve our IQ is still a hotly debated topic in psychology circles but new research shows it's a possibility.
Researchers have previously shown that a person's IQ is highly influenced by genetic factors, and have even identified certain genes that play a role. They've also shown that performance in school has genetic factors. But it's been unclear whether the same genes that influence IQ also influence grades and test scores.
We concluded that prolonged intensive training in creative problem-solving can lead to substantial and positive effects on intelligence during late adolescence (ages 18–19).
Albert Einstein likely never took an IQ test but is estimated to have a 160 IQ—but even that can't stand up to these masterminds.
But there once lived a person whose IQ was said to be between 250 and 300! William James Sidis, the most intelligent man to ever walk the Earth, was a child prodigy and an exceptional mathematician. He was a master at multiple dialects and a gifted author as well. But sadly, not many people have ever heard of him.
The cause of the IQ decline is due to environmental factors, and not genetics, said Ole Rogeburg, a senior research fellow at Ragnar Frisch Centre and co-author of the study on IQ scores, published in the Proceedings of the National Academy of Sciences journal.
Multiple studies have shown that while chess playing does improve cognitive, memory, and math skills, it doesn't necessarily translate into higher test scores. Research has produced mixed results on the effects of playing chess on test scores.
