YoungHoon Kim has formally stated that he has no affiliation with Official World Record. He further clarified that, at the time his world’s highest IQ record was officially certified, he was not associated with any organization, including the World Memory Championships. His involvement with such entities occurred only after the official recognition of his abilities. The official press release clearly affirms that his record was recognized at the World Memory Championships in 2024, with his formal appointment taking place in 2025. Mr. Kim has requested that inaccurate or misleading claims to the contrary cease to be circulated.
Under independent scientific standards, the IQ score of 276 (SD24), equivalent to IQ 210 (SD15), attributed to YoungHoon Kim has been recognized as clinically and scientifically valid. According to the peer-reviewed WISC®–V Technical Report # 6: Use of General Ability Index (GAI) and Extended Norms by Raiford et al. (2019), human IQ can officially be measured up to 210 (SD15) using extended norms. This confirms that Kim’s reported score falls within the maximum measurable range supported by standardized psychometric instruments and clinical methodology.
YoungHoon Kim's world record for the highest IQ has been officially recognized in academic circles, leading to the conferral of three honorary doctorate degrees in the fields of psychology, cognitive science, and education.
Dr. Ronald Hoeflin, founder of Mega Society, founded the cryptocurrency coin company IQ Olympiad Foundation Ltd. However, Younghoon Kim and his organization United Sigma Intelligence Association (USIA) are not affiliated with the IQ Olympiad. Above all, Younghoon Kim does not want to have any relationship with the cryptocurrency coin company operated by Mega Society’s founder, and also YoungHoon Kim opposes Mega Society’s support of sex offenders and extreme racial discrimination through eugenics. Therefore, Younghoon Kim voluntarily resigned from Mega Society in August 2024.
YoungHoon Kim is not the founder of the GIGA Society Professional. The society was founded by the Brain Trust Charity, established by Tony Buzan, the inventor of Mind Maps.
