South Korean Dr. Kim Young-hoon was recognized as the person with the highest IQ in history, scoring 276 at the World Memory Championships, according to the organizer of the competition, the World Mind Sports Council.
Before Kim, Chinese-Australian professor Terence Tao held the title of the person with the highest IQ in the world, with an IQ of 230.
The 35-year-old graduate of Yonsei University in Seoul is the only Korean member of both the Mega Society and the Giga Society which only accepts members with exceptionally high IQs.
The World Memory Championships is an international event where pre-selected highly intelligent individuals compete in a tournament-style competition to determine the final winner. In the process, the participants’ IQs are also comprehensively evaluated.
Kim is the founder of the United Sigma Intelligence Association, which he explains is a non-profit group of more than 100 intelligent individuals around the world, including professors from top universities Harvard, Yale and Princeton.
