Scientists have conducted detailed research on IQ scores:

• Below 85: Very low IQ.
• 85 - 115: Average IQ.
• 115 - 130: Intelligent.
• 130 - 145: Very intelligent.
• Above 145: Genius or near-genius level.

Top 10 People with the Highest IQs on the Planet

Many individuals worldwide possess extraordinary intelligence. They come from different backgrounds and pursue various careers. However, they all share one common trait: having the highest IQs in the world.

He authored four books on anatomy and astronomy. Additionally, he was fluent in eight languages: Greek, French, Russian, German, Hebrew, Turkish, Armenian, and Vendergood (a language he created himself).

After graduating from Harvard, William became a mathematics professor at Rice University. However, he left his teaching career after being mocked by students as a "child professor."

Later in life, he became entangled in legal troubles due to his involvement in socialist movements and passed away at the age of 46. Despite his troubled later years, with an IQ estimated between 250 and 300, William is still remembered as one of the most intelligent people in world history.

Despite this, Da Vinci remains a renowned genius across multiple fields. In 1509, he was one of the first to theorize why the sky appears blue. His visionary ideas included inventions far beyond his era, such as tanks, humanoid robots, computers, and flying machines.

Though he did not construct these devices himself, his futuristic concepts were groundbreaking. Among the top three individuals with the highest IQs in history, Da Vinci is the only one with an illustrious legacy of achievements.

Position 4: Terence Tao

Terence Tao is the most outstanding mathematician of his time. He is an Australian-American of Chinese descent and has an IQ ranging from 220 to 230.

At the age of 24, he became a professor of mathematics at the University of California (Los Angeles, USA) and became the youngest person to be recognized as a professor there. At the same time, he also participated in scientific research, and made great contributions to analysis related to the Kakeya hypothesis and luminous mapping.

In 2005, Terence Tao and Allen Knutson won the Levi L. Conant Prize of the American Mathematical Society. Then in 2006 at the 25th International Congress of Mathematicians in Madrid, he was one of the youngest people, the first professor from the University of California to win the Fields Medal (award for contributions to Mathematics by young mathematicians).

Position 5: Marilyn Savannah

Marilyn vos Savant was once recognized by Guinness as the person with the highest IQ on the planet at 228 and is the only woman on this list. Some people think that her IQ rank should be higher than Terence Tao, this is still controversial. She was born in 1946 in Missouri (USA), her parents are of German and Italian descent.

Marilyn vos Savant was once noticed by scientists and asked to participate in research programs, but she refused. She studied at the University of Washington but dropped out after 2 years and did not graduate.

Marilyn pursued a career in securities and real estate but was unsuccessful and turned to writing. After marrying Dr. Robert K. Jarvik - one of the inventors of the artificial heart used in medical surgery, her life became more private.

It can be said that compared to the characters with the highest IQ in the world, Marilyn's life is not as glorious as people often imagine.
