IQ is an acronym for "intelligence quotient". It is a score derived from various standardized tests designed to measure people's intelligence. French psychologist, Alfred Binet developed the concept first in 1905 by constructing an IQ test. His reason behind inventing the IQ test was to test the knowledge for children in order to find out which of them would require additional academic help. Today, the test is used regularly and is based on a model of the Stanford Binet Intelligence scale. Using the IQ tests for decades now, finding the score in the world is not impossible.

People With the Highest IQs

Although there isn't enough data available on the score in the world by an individual, there is information on the person, or should I say, persons. So what is this high number yet? Here are our top 2 finalists.

Marilyn Vos Savant
The score in the world ever recorded is of Marilyn Vos Savant who scored 228 in the test. Savant is an American magazine columnist, author, playwright, and lecturer. Her name has been enlisted in the Guinness World Records for being able to receive such an astounding score. She writes a column, Ask Marilyn for the Sunday edition of the Parade Magazine and solves her readers' queries on a wide range of topics and puzzles.

Kim Ung-Yong
Our other finalist to hold the highest score in the world title is Kim Ung-Yong from Korea. Kim showed extraordinary intellectual abilities since he was 6 months old. At the age of 3, Kim could read Korean, English, German, and Japanese fluently, and by age 6, he was able to solve calculus problems which he saw on television. He was the first kid to have been invited to NASA by the U.S. at the age of 7. He finished his Ph.D. in Physics before he was 15. In the year 2010, Kim made his way to the Guinness World Records for being able to receive a score of 210.

Of course, apart from these famous people, there are others who have made scored incredible scores. Christopher Michael Langan who lives in Missouri, US has a score of 195, Philip Emeagwali born in Nigeria has a score of 190, and the world chess champion Garry Kasparov has a score of 190. Quite impressive, aren't they?

Highest IQ Country

Collecting information on the highest IQ possible of various countries require lot of time, resources, and so much more. Plus, conducting IQ tests worldwide would be something of a "herculean" task. That is why scientists use an approximate value by acquiring average scores of neighboring nations.

The Scoring System

Modern scoring is based on various standardized tests which are specifically designed to evaluate a person's intelligence. These scores are used for various purposes; right from predicting educational achievements, to special needs, job, or income. Scientists study the world's score and reveal a number of qualities and predictions based on it. This score is used to test a person's abilities to make decisions, like a test before entering a company for a job. Scores of tests like intelligence quotients are also considered. The score range and intelligence classification is a standardized way to measure any individual's intellect, however the category names may vary. To understand the calculating process, a general reference table is mentioned below.

120 - 129High Intelligence
110 - 119Superior Intelligence

35 - 50Moderate Mental Disability
20 - 35Severe Mental Disability

When you put your mind to it, you can actually achieve anything. And that same theory applies here as well. IQ tests and the scoring methods/techniques have been in continuous debate, as to which influences the scores, nature or nurture. But, one thing is for sure, as long as our civilization has brilliant minds like Savant and Ung-Yong, who's to know what will come next. The highest score for a person and country will keep going further as both nature and nurture play equal parts.
