People with the Highest IQ in the world

I know you are already expecting to see names like the legendary Stephen Hawking, or the great Albert Einstein on the list as they are famously recognized for their high IQ. You are not short from your expectation. But, However, when it comes to Intelligence Quotient or “IQ”, and who possesses the highest of it, you will be surprised to see who comes at number one. It has over the years become a topic of discussion to try and measure someone’s intelligence. Most people believe that some of these super intelligent people are born with the ability, others are of the opinion that these people had to work really hard as they grow older. But, whichever it is, one thing is for sure, they are the smartest ones amongst us.

The average IQ is 100, any above that is considered a genius. So, who are the people with the highest IQ? Let’s find out…

We sure can’t talk about IQ and not make mention of one of the greatest minds of our time, Stephen Hawking. He was a professor, a theoretical physicist, and a renowned writer. He authored the book “A Brief History of Time” which sold more than 10 million copies globally. Stephen Hawking was the Mohammed Ali when it comes to the study of black holes. It was his area of specialization before his death in 2018. Stephen Hawking, before his death, had struggled with mycotrophic Lateral Sclerosis (ALS), a sickness that made him incapable of moving any part of his body. However, his condition didn’t stop him for doing what he loved the most, physics, which saw him become a symbol of knowledge and intelligence in the field, an honor he so rightly deserved!

16. Albert Einstein (IQ- 160-190)

This man needs no introduction. His name alone sounds like a synonym to genius. Albert Einstein comes next as the person with the highest IQ. He is of the greatest minds in history and has shaped the future of science during his time. Einstein was honoured with a Nobel Prize for his discovery of the law of photoelectric effect. He also invented the theory of relativity.
Einstein was truly a genius, and calculating his IQ gave researchers a bit of a problem so they had to rely on estimating his test score by analyzing his papers thoroughly. You have to be at some god-level of genius to have scientists and researchers go through all that just to prove how smart you are!
