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 Albert Einstein's IQ?
Albert Einstein's IQ is most commonly estimated at around 160. The number is a retrospective estimate, not a public result from a modern standardized IQ test.
Why is that estimate so common?
Einstein became the cultural shorthand for genius. His role in transforming physics made people want a numerical expression of his intellectual status, and ~160 became the most common answer attached to that instinct.
That estimate is plausible as a historical shorthand, but it should still be framed as inferred, not verified.
Bottom line
A balanced conclusion is that Einstein's IQ is widely estimated around 160, but the real evidence lies in his scientific output, not in a surviving test 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.
