Historical scientist IQ estimate
Updated by TestYourIQ Research Desk. This page summarizes public evidence and treats celebrity IQ figures as estimates unless an official score is publicly documented.
What was Stephen Hawking's IQ?
Stephen Hawking's IQ is often estimated at around 160, though no public official record confirms the number. The estimate reflects his scientific stature more than a published test document.
Why does the estimate persist?
Hawking's work in cosmology, black hole physics, and mathematical reasoning makes him an obvious target for IQ speculation. The estimate persists because his public intellectual profile matches what people imagine a very high IQ scientist to look like.
Bottom line
The strongest version of the claim is that Stephen Hawking's IQ is commonly estimated around 160, but the number remains an estimate, not a publicly documented score.
Sources and references
These references support the biographical and contextual claims on this page. The IQ figure itself should still be read as an estimate unless the subject has a public, verified score on record.
