Frequently Asked Questions

No matter who has the lowest IQ in the world, people always care about genius minds, and that is why we have created this list of the people with the highest IQ scores. We hope you now know what is the highest IQ score ever recorded until now, and if you have some questions, consider reading the FAQ section below to see our answers to the most common queries.

What Is IQ of Bill Gates?

Bill Gates’ IQ is estimated to be around 157 which is very low compared to other people on this list of the highest IQ in the world. This estimate is based on his exceptional performance on the SAT exam during his time as a student. A score of 157 is considered to be in the top 0.1% of all scores. It demonstrates Gates’ strong abilities in math, critical reasoning, and problem-solving, and definitely not how intelligent he is.

What Ethnicity Has The Highest IQ Scores?

While IQ can vary significantly within all groups, some research has indicated that Ashkenazi Jews, on average, tend to score higher than other ethnicities. Their average is generally considered to be around 107-115. However, socioeconomic environments must also be taken into account. Nevertheless, outstanding individuals can be found among all ethnicities.

Does IQ Increase With Age?

IQ scores have a propensity to rise slightly during childhood and teenage years as different parts of the brain develop but that won’t give you the highest IQ in the world. However, starting in our late 20s, the prefrontal cortex begins ageing, potentially causing IQ to decline very gradually. On the other hand, life experiences and knowledge accumulated with age can compensate for natural cognitive changes to an extent.

Can IQ Be Improved?

While IQ was once thought to be fixed, some studies indicate it may be possible to boost scores. Regular practice of skills like logic games, math problems, and memory exercises can help strengthen and expand neural pathways in the brain. However, most experts concur that IQ elevations following training may not hold permanently.

At What Age Is Your Brain The Sharpest?

Generally, the brain reaches its intellectual peak sometime during the early to mid-20s. This corresponds with the prefrontal cortex reaching full maturation, allowing for optimal reasoning, planning, and abstract thought. Skills learned during these years tend to be retained best. However, mental agility also remains high through around age 30.
