How do you measure how smart a celebrity is?
We scored three things: the level of the credential (doctorate beats bachelor’s), original work such as papers, patents and theorems, and how far the person went beyond entertainment. We did not use IQ numbers, because celebrity IQ claims are rarely documented.
1. Brian May: PhD in astrophysics
Brian May started his doctorate at Imperial College London in 1971, left to pursue music with Queen, and was awarded the PhD in 2007. His thesis was titled “A survey of radial velocities in the zodiacal dust cloud”.
He served as chancellor of Liverpool John Moores University from 2008 to 2013, and was a science team collaborator on NASA’s New Horizons mission to Pluto. The asteroid 52665 Brianmay is named after him, and he was knighted in the 2023 New Year Honours.
2. Mayim Bialik: PhD in neuroscience
Mayim Bialik earned a bachelor’s degree in neuroscience from UCLA in 2000 and a PhD in neuroscience in 2007. Her dissertation examined the hypothalamic regulation of behaviors in Prader-Willi syndrome.
She played neuroscientist Amy Farrah Fowler on The Big Bang Theory from 2010 to 2019, and has written several books and hosts a podcast on mental health.
3. Natalie Portman: Harvard psychology and published research
Natalie Portman graduated from Harvard in 2003 with a psychology degree. As a teenager she co-authored a science paper entered in the Intel Science Talent Search, and in 2002 she contributed to a published memory study using near-infrared spectroscopy.
She later spent six months taking graduate courses at the Hebrew University of Jerusalem, and won the Academy Award for Best Actress for Black Swan.
4. Danica McKellar: mathematician and author
Danica McKellar graduated summa cum laude in mathematics from UCLA in 1998. As an undergraduate she co-authored a paper whose results are now called the Chayes-McKellar-Winn theorem.
She has written several math books for middle-school and high-school girls, including Math Doesn’t Suck and Kiss My Math.
5. Hedy Lamarr: the film star who co-invented frequency hopping
Hedy Lamarr and composer George Antheil were granted U.S. patent 2,292,387 on August 11, 1942, for a secret communication system based on frequency hopping. The idea underlies later wireless technology.
Lamarr died in 2000. She received the Electronic Frontier Foundation Pioneer Award in 1997 and was inducted into the National Inventors Hall of Fame in 2014.
6. Lisa Kudrow: biology graduate and headache researcher
Lisa Kudrow studied biology at Vassar College and planned to follow her father, Dr. Lee Kudrow, a headache specialist. She worked for him for eight years and received a research credit on a study of cluster headache in left-handed people, published in Cephalalgia in 1994.
She then became famous as Phoebe Buffay on Friends, and she returned as Valerie Cherish in the third season of The Comeback in 2026.
7. Dolph Lundgren: chemical engineer turned action star
Dolph Lundgren studied chemical engineering at Washington State University, Clemson University and the Royal Institute of Technology in Stockholm, then earned a master’s in chemical engineering at the University of Sydney in 1982.
In 1983 he won a Fulbright Scholarship to MIT but left after two weeks to act. He speaks Swedish and English fluently and has lead roles in more than 80 action films.
8. Jodie Foster: Yale graduate and French speaker
Jodie Foster was valedictorian of the French division of her school, the Lycée Français de Los Angeles, in 1980. She graduated magna cum laude from Yale in 1985 and received an honorary Doctor of Fine Arts from Yale in 1997.
She is fluent in French and led the French-language film Vie privée in 2025. She has won two Oscars, for The Accused and The Silence of the Lambs.
9. Mira Sorvino: Harvard honors and Mandarin
Mira Sorvino graduated from Harvard magna cum laude in 1989 with a degree in East Asian studies, after a year as an exchange student in Nanjing studying Mandarin.
She won the Academy Award for Best Supporting Actress for Mighty Aphrodite in 1995, served as a United Nations Goodwill Ambassador for combating human trafficking from 2009 to 2012, and made her Broadway debut in Chicago in September 2025.
10. Conan O’Brien: Harvard Lampoon president
Conan O’Brien was valedictorian at Brookline High School in 1981, then graduated from Harvard in 1985 magna cum laude in history and literature. He served as president of the Harvard Lampoon.
He hosted the 97th Academy Awards on March 2, 2025, and received the 2025 Mark Twain Prize for American Humor.
Who was removed from the list, and why?
We dropped Quentin Tarantino, James Franco, Ben Stein and the earlier claims of IQ scores for Tarantino and Lundgren. Their ranking relied on IQ numbers or on degree claims we could not verify against current records. Brian May, Danica McKellar and Hedy Lamarr join because their achievements are documented.
