Nobel affiliations
University of Edinburgh Nobel laureates: the official names
The Nobel Prize API lists three individual laureates with an Edinburgh prize affiliation—not an alumni list and not a university IQ ranking.
Begin investigation 02EstimateDid any Nobel laureate publish a real IQ score?
The official prize list is not an IQ table. Listicles invent 160s because the public wants a number.

How IQ Is Estimated for Presidents Without Test Scores
No U.S. president has taken a published IQ test. Here is the method behind the numbers—and what it cannot do.
Begin investigation 02EstimateBarack Obama's IQ Estimate: The Ages 18-26 Evidence
Columbia, a thesis on nuclear disarmament, published writing, and community organizing. What the biographical record supports—and what it does not.
Begin investigation 03EstimateDonald Trump's IQ Estimate: The Ages 18-26 Evidence
Fordham, a family-connected Wharton transfer, no honors, and no intellectual output. The thinnest academic record of the three modern presidents.
Begin investigation 04EstimateJoe Biden's IQ Estimate: The Ages 18-26 Evidence
A 1.9 GPA, bottom-of-class law school ranking, a plagiarism incident, and a failed course. The clearest negative academic signal of the three modern presidents.
Begin investigation 05Historical estimateJames Garfield’s IQ: the Simonton 2006 2C number
Garfield’s displayed IQ in this atlas is 152—Table 1 column II-C—not a classroom test.
Begin investigation 06Historical estimateWho has the highest presidential IQ on Simonton 2C?
John Quincy Adams is 175 on Table 1 II-C. That is the top of a historiometric ranking, not a test leaderboard.
Begin investigation 07Historical estimateJefferson vs Lincoln vs Kennedy: three Simonton 2C numbers
Jefferson 160, Lincoln 150, Kennedy 160 (159.8). Same table, same caveats, three integers.
Begin investigation 08EstimateWhy Trump, Obama, and Biden are not on Simonton 2006
The paper stops at George W. Bush. Later presidents get labeled informal estimates—not a fake extra 2C column.
Begin investigation 09Historical estimateThe scholar-president IQ myth
Degrees and books are not IQ tests. Wilson’s doctorate and Adams’s 175 sit on different kinds of evidence.
Begin investigationHawking and physicists
What was Stephen Hawking’s IQ?
This atlas displays 160 as an informal circulating estimate. No published administered score was found.
Begin investigation 02EstimateEinstein, Hawking, Feynman: three physicists, three evidence grades
160 disputed, 160 informal, 125 reported. None is a verified adult Full Scale IQ in this atlas.
Begin investigation 03Official measureWhy Stephen Hawking did not win a Nobel Prize
No medal, no IQ implication. Nobel rules and physics evidence are not an intelligence ranking.
Begin investigationWhat 160 means
What does a 160 IQ mean on the scale?
About the 99.997th percentile on a mean-100, SD-15 model—roughly 1 in 31,000 at or above. That is statistics, not Einstein.
Begin investigation 02Disputed claimWhy the internet says genius = 160
Pop culture glued genius to 160. Test publishers did not. Einstein listicles did the rest.

Follow the famous number back through the evidence—and watch the trail disappear.
Begin investigation 02Historical estimateCan U.S. Presidents Be Ranked by IQ?
A published model exists for early presidents, but its numbers are estimates—not test results.
Begin investigation 03Research estimateWhat Does a State IQ Estimate Measure?
The Pesta 2022 values are published research composites built from NAEP and PIAAC—not statewide IQ tests.

HLO, Learning Poverty, minimum proficiency, and HCI+ answer different questions.
