What was Howard Hughes’ IQ?
He set a 352 mph landplane speed record in 1935 and flew around the world in 1938: the flights are on record, an IQ score is not.
No IQ test result has been published for Howard Hughes, and no sourced IQ figure circulates for him. The documented record is a 352 mph landplane speed record in 1935, a round-the-world flight in 1938 and the founding of Hughes Aircraft in 1932. A Howard Hughes IQ score is therefore an inference, as of November 2026.
Howard Hughes’ estimated IQ
- Math and aeronautical engineering courses at Caltech, after Fessenden School in 1921 and a brief stint at the Thacher School, according to Wikipedia’s biography.
- The Hughes H-1 Racer, designed by Hughes and Richard Palmer and built by Glenn Odekirk, set a world landplane speed record of 352 mph at Santa Ana, California, on September 13, 1935, per the Smithsonian National Air and Space Museum.
- A Los Angeles to Newark record flight in the H-1 on January 19, 1937, in 7 hours, 28 minutes and 25 seconds at an average of 332 mph (Smithsonian).
- A flight around the world completed on July 14, 1938, in about 91 hours in a Lockheed 14 Super Electra, almost four days faster than Wiley Post’s 1933 record, per Wikipedia.
- The Harmon Trophy (1936, 1938), the 1938 Collier Trophy, a 1939 Congressional Gold Medal and induction into the National Aviation Hall of Fame in 1973 (Wikipedia).
This is an inference from engineering and flying results, not from a test. Wikipedia lists no completed degree (Rice University, left in 1924; Caltech courses), and an inherited fortune paid for much of the work, so the range is lower in confidence than for degree holders. It matches Henry Ford’s band rather than the highest business ranges.

What an IQ of 130–150 actually means
Set the claim aside for a moment. If someone genuinely scored in this range, here is what that would represent.
| Score range | Classification | Share of people | What it indicates |
|---|---|---|---|
| 85 – 114 | Average | ~68% | The range most people fall into. |
| 115 – 129 | Above average | ~13.6% | Roughly one person in seven. |
| 130 – 144 | Gifted | ~2% | The threshold most high-IQ societies use. |
| Above 144 | Highly gifted | ~0.1% | Figures above this range are extrapolated from the curve rather than measured. |
Percentages are approximate and describe a normal distribution. The same number means different things on tests with different standard deviations.
Thirty questions gives you a measured position on this exact scale — your score, your percentile and the ability breakdown behind it.

Who was Howard Hughes? Howard Robard Hughes Jr. was born on December 24, 1905, in Houston and died there on April 5, 1976, according to Wikipedia. His father founded the Hughes Tool Company in 1909, and after his father died in 1924, Hughes inherited 75% of the family fortune; on his 19th birthday he was declared an emancipated minor with full control of his money. He attended Fessenden School in Massachusetts in 1921, took math and aeronautical engineering courses at Caltech, and dropped out of Rice University in 1924.
What did Howard Hughes build and fly? In 1932 he founded the Hughes Aircraft Company. The Smithsonian National Air and Space Museum records that the H-1 Racer, designed by Hughes and Richard Palmer and built by Glenn Odekirk, set a world speed record of 352 mph at Santa Ana, California, on September 13, 1935, and flew from Los Angeles to Newark in 7 hours, 28 minutes and 25 seconds on January 19, 1937.
On July 14, 1938, Wikipedia says, Hughes completed a flight around the world in about 91 hours in a Lockheed 14 Super Electra with a crew of four, beating the 1933 record of 186 hours by almost four days.
Was Howard Hughes a genius? “Genius” is a label, not a score. His documented honors are the Harmon Trophy (1936 and 1938), the 1938 Collier Trophy, a Congressional Gold Medal in 1939 and the Octave Chanute Award in 1940, and he produced the films The Racket (1928), Hell’s Angels (1930) and Scarface (1932).

Why no figure circulates
Following a claim back to its first appearance is the part almost nobody does — and it is what most people are actually asking.
Howard Hughes IQ score searches lead to no number. No IQ test result for Howard Hughes appears in Wikipedia’s biography or in the Smithsonian’s record of his H-1 Racer, and no source behind this page states a figure. A number found in a forum thread, including a thread that turns up for “Howard Hughes IQ Reddit,” is opinion: it names no examiner, test or date. For how circulating numbers form, see where celebrity IQ numbers come from.
What is Howard Hughes’ estimated IQ if he was never tested? The honest answer is a range inferred from documented achievement, 130–150 here. That matches Henry Ford (130–150), sits just below Jeff Bezos (145–155) and overlaps Elon Musk (140–150). On the usual scale (mean 100, SD 15) a 130 is about the 98th percentile and a 150 about the 99.96th.
Did Howard Hughes have a high IQ? Nothing published shows it as a measured fact. The reputation rests on results anyone can check: a landplane speed record, a transcontinental record and a round-the-world flight. For how wealth and measured intelligence relate, see the IQ of billionaires, and for pilots as a group, the average IQ of pilots.

The sources behind our estimate
The figures that circulate for Howard Hughes, what we were able to confirm, and where the two diverge.
People search for a Howard Hughes IQ score and for “Howard Hughes IQ Reddit” threads. No page that states a specific figure for him was found.
No IQ score appears in Wikipedia’s biography of Hughes or in the Smithsonian’s record of the H-1 Racer, and no source behind this page names a test, examiner or date for one. A number quoted in a forum post would be opinion, not a result.
With no circulating figure to audit, the range is the only number on the page. It matches Henry Ford’s 130–150 and sits just below Jeff Bezos’s 145–155, and it rests on a record of designing and flying aircraft, not on a measurement.

Howard Hughes — frequently asked
What was Howard Hughes’ IQ?
No IQ test result for Howard Hughes has been published, and no sourced IQ figure circulates for him. This site’s estimated range, inferred from his documented record, is 130–150 on a scale with mean 100 and SD 15. The record includes a 352 mph landplane speed record in 1935 and a round-the-world flight in 1938.
What is Howard Hughes’ IQ score?
Howard Hughes’ IQ score is not documented. No test name, examiner or date is attached to any number quoted for him, so any score is unsourced. His documented record, from Caltech engineering courses to the H-1 Racer and Hughes Aircraft, supports an estimate of 130–150, not a score.
Is there a Howard Hughes IQ number on Reddit?
A figure for Howard Hughes found in a Reddit thread or any forum is opinion: a post names no examiner, test or date. No IQ test result for him appears in Wikipedia’s biography, the Smithsonian’s H-1 Racer record or any source used for this page.
Did Howard Hughes have a high IQ?
No published source shows it as a measured fact. The reputation rests on checkable results: a 352 mph landplane speed record in 1935, a Los Angeles to Newark record in 1937 and a round-the-world flight in about 91 hours in 1938. Those support a high estimate, 130–150 here, not a score.
Was Howard Hughes a genius?
“Genius” is a label, not a score, and no test result supports or refutes it. The documented record is engineering study at Caltech, an aircraft he co-designed that set a 1935 speed record, a 1938 world flight and the Harmon, Collier and Congressional Gold Medal honors.
What did Howard Hughes study?
Howard Hughes took math and aeronautical engineering courses at Caltech and attended Rice University before dropping out in 1924, per Wikipedia. Wikipedia’s biography lists no completed degree, which is why this site’s range for him is lower in confidence than for degree holders.
How does Howard Hughes’ estimated IQ compare with Elon Musk’s or Henry Ford’s?
This site rates Howard Hughes at 130–150, Elon Musk at 140–150 and Henry Ford at 130–150, so the ranges overlap and no ranking is supported. All three are inferred from documented achievement, not tests, and none is a measured IQ.
How does my IQ compare with Howard Hughes?
You can find out in about fifteen minutes. The IQ Metrics assessment is 30 questions, scored on the same 100-mean scale used throughout this page, so your result and the estimate above are at least expressed in the same units — one measured, one inferred. Once you have a number, the leaderboard shows where it would sit, and how we score and norm it explains the benchmarking.
