No one officially has a 400 IQ, as standard tests have limits, but the claim is often linked to Adragon De Mello, who graduated college at age 11 with a projected 400 IQ, though this score is disputed and not from a standard test. Actual high IQs are around 200-225, with figures like Marilyn vos Savant and Christopher Hirata holding high, record-setting scores, but 400 is considered outside the realm of reliable testing and human possibility.

Among them, several names and their extremely high IQ scores are worth mentioning:

  • Adragon de Mello (400),
  • Ainan Celeste Cawley (263),
  • Michael Kearney (200-325),
  • William James Sidis (200-300),
  • Kim Ung-Yong (200 to 210),
  • Sho Yano (200),

Bearing these caveats in mind, it is generally believed that the highest IQ score ever recorded is that of William James Sidis, who is believed to have had an IQ of between 250 and 300.
