10 Highest IQ Scorers

Browse By


  IQ or Intelligence quotient is what a person scores after taking one of the many standardized tests. These tests are supposed to measure the intelligence level of individuals. As the score can vary from tests to test, an IQ score is always inexact. This is one of the reasons the Guinness Book of World Records eliminated the Highest IQ category long ago. A high IQ can be a result of genes or nourishment or hard work, it is highly debatable. And 95% of the people scores between 70 and 130 which is the score of average intelligence. Also, having a high IQ doesn’t always mean the person is the smartest. Genius legends including Albert Einstein and Stephen Hawking both have an estimated IQ of 160 but they don’t even feature on this list. Having a high IQ means you are great at solving mathematical and logical reasoning. On this list, we’re mentioning the 10 Highest IQ Scorers.
