Have you ever wondered what your IQ score is, and how you measure up to everyone else on the planet? You can take a test, of course, and find out.
What Is An IQ Score?
“IQ” stands for Intelligence Quotient. Standardized tests culminate answers through a series of questions and problems in various fields. These fields work together to give a cross-section of someone’s intelligence.
There are multiple classifications of IQ scores. Here are two of the most commonly used.
Current Wechsler (WAIS – IV, WPPSI – IV) IQ Classification
Stanford – Binet Fifth Edition (SB5) Classification
How Do We Figure Out An IQ Score?
Someone’s mental age score comes from taking an intelligence test. This score is then divided by the person’s chronological age. This figure is then multiplied by 100, and the result is the person’s IQ score.
The Smartest People Who Ever Lived
#1 – William James Sidis
The guy with the highest IQ score ever recorded is William James Sidis. His recorded score capped out between 250 and 300, though his actual intelligence could possibly have been higher.
Mr. Sidis was an American child prodigy, with immense mathematical and linguistic skills.
If you’ve ever heard of people talking about “Dark Matter,” you can thank Mr. Sidis for inciting the conversations with his postulations.
#2 – Terrance Tao
With an IQ score between 225 and 230, Mr. Terrance Tao, born in Adelaide Australia, exhibited tremendous intelligence at an early age. He was teaching older children how to spell and do mathematics when he was only 2 years old.
He was the youngest professor ever at UCLA.
#3 – Sir Isaac Newton
Isaac Newton was around before standardized intelligence tests were ranking “genius” and “average” for the world. But based on the intelligence displayed throughout his lifetime, his IQ score is estimated to be around 193.
Sir Isaac Newton was a major influencer in the world of mathematics and scientific thought for the 300 years following his discovery of gravity, and the writing of his book Philosophiæ Naturalis Principia Mathematica.
#4 –Albert Einstein
This man’s very name is synonymous with genius in most people’s minds. His clever quotes, famous “E=MC₂” formula, and personality helped to make him a darling for many.
And despite all the rumors, Einstein did not fail out of his math classes, but in fact had already mastered calculus by the age of 15.
#5 –Marilyn Vos Savant
Marilyn Vos Savant was once placed in the Guinness Book of World Records for having the highest IQ in her era. Varying tests have scored her IQ between 186 and 228, depending on a few different factors. She’s written a column called “Ask Marilyn” for Parade Magazine, and books coming out from those columns.
#6 – Stephen Hawking
Mr. Hawking had ALS, or Lou Gehrig’s disease, which caused him to lose voluntary control of his muscles – which is why he was in the wheelchair, and a speech-generating device so well-known in his talks on science, and those common pop culture references.
Mr. Hawking specialized in theoretical physics and cosmology.
#7 – Judit Polgar
Everybody knows chess players are the smart ones. Judit Pulgar is one of those amazing chess masters. In fact, she beat the famous Bobby Fischer at the age of 15, and became the youngest Grandmaster. It’s believed that her IQ score is approximately 170.
Judit became the International Master, and both of her sisters, also educated around chess in their home growing up, are Grand Masters.
#8 – Leonardo da Vinci
The famous painter, known for the Mona Lisa, the Last Supper, and the Vitruvian Man was also a great contributor to the world of science and innovations.
It’s estimated that the inventor of the flying machine driven by a man-powered rotor, and aerial screw – basically a helicopter – had an IQ score of about 220. That score would place him squarely in the top five smartest people who ever lived.
The Smartest People In The World
These amazingly brilliant people have made the world a better place through their various works in the mathematics and sciences. Some, like da Vinci, have added inventions that still influence our technology. Others, like Einstein and Newton, made discoveries that have changed the face of science and medicine throughout the generations after them.
