With so many intelligent people out there, it becomes quite a difficult task to determine the smartest one. However, in this article, we will discuss some of the most intelligent people on the planet and try to uncover the smartest person on earth in 2020.

1. Who is the Smartest Person on Earth 2020?

As we mentioned earlier, it’s quite challenging to determine the smartest person in the world. Some individuals may possess remarkable knowledge in certain areas or have exceptional creativity, whereas others may have remarkable problem-solving skills or critical thinking abilities. But when it comes to determining the smartest person on earth in 2020, we can take help from some of the most widely acknowledged IQ tests.

The Smartest Person on Earth 2020 According to IQ Tests

The Intelligence Quotient (IQ) test is one of the most popular standardized tests that measure human intelligence. Since the introduction of this test, it has been widely used to measure intelligence among adults worldwide. The highest possible score for an IQ test is 200, and only few people have ever scored above 190.

So, when we talk about the smartest person in the world, we can have a look at the people who have scored exceptionally high on IQ tests. According to the latest data, a man named Dr. Evangelos Katsioulis, who is a Greek psychiatrist, has an IQ score of 198, which is considered to be the highest score in the world.

Who is Dr. Evangelos Katsioulis?

Evangelos Katsioulis, born on August 19, 1976, is a Greek doctor, psychiatrist, and a member of the Hellenic Society of the History of Medicine. He has been widely recognized as one of the smartest individuals in the world, especially after he scored a remarkable 198 on an IQ test, which is an impressive feat.

Dr. Katsioulis has a deep interest in a variety of fields, including science, philosophy, and history. He has also been involved in the field of medical research and has published various papers in different medical journals.

2. Other Smartest People in the World

As we mentioned earlier, intelligence comes in different forms, and it would be unfair to compare individuals based on a single score, no matter how high that score is. There are many individuals in the world who have exceptional mental capabilities, and some of them are:

Stephen Hawking

Stephen Hawking was an English theoretical physicist and one of the greatest minds of the 20th century. He was known for his groundbreaking work on black holes and the origins of the universe. Despite being diagnosed with a rare motor neuron disease at a young age, Hawking’s curiosity and creativity did not stop him from making remarkable contributions to the field of science.
In his lifetime, he penned numerous books including “A Brief History of Time”, which became a best-seller worldwide.

Judit Polgar

Judit Polgar, born in Budapest, is a Hungarian chess player and is widely considered to be the greatest female chess player in history. At the age of just nine, she became the youngest player ever to be awarded the title of International Master.

She has defeated some of the greatest players in the world, including former World Champions Boris Spassky, Anatoly Karpov, and Garry Kasparov. She retired from professional chess in 2014, leaving behind a legacy that will be remembered for generations to come.

3. IQ and intelligence – Are they the same?

There is a popular misconception that IQ and intelligence are the same things. Intelligence is a broader term that encompasses a wide range of skills, including critical thinking, problem-solving, creativity, and memory skills.

On the other hand, IQ is a standardized test that is specifically designed to measure cognitive abilities, and hence, it is limited in its scope. While a high IQ score can be a sign of exceptional intelligence, it doesn’t always guarantee it.

4. How to Improve Your Intelligence

If you’re intrigued by intelligence and would like to improve it, there are a few things you can do:

  • Challenge Your Brain: The brain is like a muscle, and like any other muscle, it needs regular exercise to remain healthy. So, try new things, read books, work on puzzles, and keep testing your brain.
  • Stay Curious: Stay curious about the world around you, and keep asking questions. Curiosity is a great way to expand your horizons and improve your knowledge.
  • Sleep Well: Sleep is essential for the brain to function correctly. So, make sure you get at least 7-8 hours of sleep every night to help your brain perform at its best.
  • Take Care of Your Diet: Eating a healthy diet that is rich in nutrients can help boost your brainpower.
  • Learn a New Skill: Learning something new can help improve cognitive flexibility and boost creativity.
  • Stay Positive: A positive attitude can help reduce stress and improve cognitive abilities.

5. Conclusion

Intelligence is a fascinating topic, and there are many people in the world who possess remarkable mental capabilities. While IQ tests have been used to measure intelligence for many years, it’s important to remember that intelligence is a multifaceted concept that goes beyond a single test score.

We hope that this article has provided you with a deeper insight into the world of intelligence and some of the most intelligent people in the world.
