Isaac Newton, who was born on Christmas day in 1642, is known for his work with gravity and calculus. He is often credited with inventing modern mathematics. His discoveries are still studied by scholars today, more than 350 years after he published his laws of motion.

Many people wonder if he took an IQ test today, what would his score be? Isaac Newton was very smart, but it is difficult to measure intelligence with an IQ score when someone lived hundreds of years ago. So, we can only estimate his IQ score. Luckily, many sources have tried to do just that.

Most people agree that Isaac Newton’s IQ score would be around 190 if he were to take an IQ test today.  This would make him smarter than 99.9% of the population. To put this in perspective, Albert Einstein is said to have only had an IQ score of 160, which is still higher than 99.9% of the general population and only less than 0.1% of all people who have lived on Earth.

Isaac Newton’s genius is even more impressive when you consider that he did not receive any education until the age of 12. He spent a great deal of time devoted to learning everything that he could get his hands on and taught himself nearly everything that he knew.

Newton was also known for his somewhat strange behavior, but this does not mean he was not smart. When others were arguing about things like religion and politics, Newton kept to himself. He was not interested in other people’s opinions but just wanted to focus on his work.

This seems to have helped him do his work well because he often came up with amazing discoveries by simply observing the world around him. For example, while reflecting on an apple falling from a tree, he realized that it happened the same way as the moon orbiting around Earth. This led him to realize that there must be a force pulling objects towards the ground, which we now know as gravity.

Since Newton’s time, science has developed much further and many people have been able to make great contributions of their own. But many still agree that Isaac Newton’s IQ score would still put him among the most intelligent people who have ever lived.

What is on an IQ test?

IQ tests mainly focus on measuring intelligence; however, they often do measure other skills as well.  The different types of IQ tests measure skills in these areas:

Verbal knowledge

This is the ability to understand words and meanings, including vocabulary. People who are strong in verbal knowledge tend to get higher scores on an IQ test.

Abstract reasoning

Abstract reasoning involves coming up with the relationships between objects or ideas even if there isn’t an immediately obvious connection between them. People who are strong in abstract reasoning skills tend to get high scores on an IQ test.

Spatial abilities

Spatial abilities involve visualizing and understanding spatial relationships, such as the difference between a taller and a shorter stick that represent a different line on a graph. These types of abilities also involve imagining how two-dimensional shapes would look in three dimensions or how to rotate an object without looking at it. People who are strong in spatial abilities tend to get high scores on an IQ test.


Memory involves the ability to remember words, numbers, and objects even after a short amount of time has passed. People who have good memories often do well on an IQ test.

Processing speed

Processing speed involves the ability to quickly and efficiently solve problems using information given to you. People who are good at processing speed often do well on an IQ tests.

Speed of information processing

This is the ability to understand and use new information as soon as it is presented, even if there isn’t enough time to carefully consider it. People who are good at speed of information processing often do well on an IQ test.

What are Average IQ Scores?

The average score on any IQ test is 100 with a range of anywhere from below 70 to above 130.  70 is often considered the cutoff for an intellectual disability.  Most people score somewhere around 100 on an IQ test, and almost everyone who takes a professionally administered IQ test scores below 200.

What Are Good Scores on an IQ Test?

When someone takes an IQ test, his score is compared with those of other people his age to see where he stands in comparison to his peers. For example, if he takes an IQ test and his score is higher than 98% of the people who took the same test with him, then his score would be classified as a high IQ (a score above 130).

If someone’s score is higher than 2 standard deviations above the average (meaning that less than 2% of people his age scored higher than he did), then his score would be classified as a very high IQ (a score above 145).

What Do IQ Scores Mean?

IQ scores are used to measure intelligence. However, most psychologists believe that there are other factors that influence intelligence, such as emotions and personality traits.

IQ scores can predict how well a person does in school. However, they aren’t the only factor that determines a person’s academic success. Other factors such as what his teachers think of him and whether he works hard also play a role.

IQ scores don’t measure other skills or talents that people have, such as musical ability, artistry, athletic skill, empathy, leadership ability, etc.

IQ scores are based on averages. This means that many people who get high IQ scores still have some weaknesses compared to other individuals with even higher IQ scores. For example, someone might score very highly on spatial abilities but lower than average on processing speed.

What Affects IQ Scores?

An IQ score is generally stable over a person’s lifetime. A person’s score doesn’t change much once he reaches adulthood, although scores can temporarily go up or down in certain situations (for example, if someone has an injury to the brain).

IQ scores are generally similar among members of the same family because they inherit many of the same genes that contribute to intelligence.

An individual’s environment has a lot of influence on his IQ. For example, people who are very poor or emotionally neglected often perform worse on IQ tests than other people. However, most psychologists believe that the largest influence on a person’s score is genetics rather than their environment.

IQ scores can go up and down over time because of new life experiences. When a person gets new information that he didn’t originally have or learns a skill, it can change his IQ score.
