The Brightest U.S. Presidents Ranked By IQ Score

Could there be some criteria for smartness and intelligence that entitles one to become the president? Do one have to exhibit above-average intellect to be allowed to lead

a nation? Maybe yes, and perhaps not. There could never be a definite answer to such queries. However, as they say, the more, the merrier; we wouldn’t mind having a leader who’s blessed with the best of both worlds. And, nowadays it is possible to measure the intelligence level of any individuals, including our leaders.

A University of California at Davis psychologist and researcher, Dean Simonton, did exactly what we wanted to know at a time when the nation hasn’t completely overcome the election vibes. Simonton quantified the intelligence quotient (I.Q.) of U.S. presidents. To do this, Simonton used various factors, including “openness”, “intellectual brilliance”, etc., and was able to get a clear picture of our leaders’ smartness level. We have collected the accurate data of American presidents’ I.Q.s after the age of 18.

For your information, around 70% of the people in the world have an I.Q. ranging between 85 and 115. And, for running a country, one definitely would need more than that.

Some U.S. President scored higher than others…and surprisingly there are U.S. President that we had no idea were as intelligent as they were rated. Some who we thought were clearly much smarter than others were indeed completely not whatsoever. Find out who of these U.S. Presidents is the smartest of all.

Ulysses S. Grant – IQ Score: 120

As per Simonton’s research, Grant had the lowest I.Q. among all the U.S. president elected prior to 2006. Ulysses Grant was the 18th U.S. president (1869-1877). During his youth, his classmates mocked him a lot and called him a Useless guy. Grant always struggled to fit into school and wasn’t interested in studied at all. However, he chose to join the hardest and most demanding of all professions, the Military. After graduating from West Point, he joined the Army and served with distinction. Grant was a courageous soldier and reached the position of a Commanding General. Before becoming the U.S. president, Grant led the Union Army’s Vicksburg campaign to regain control of the Mississippi River and played a fundamental role in winning the Civil War. During his presidential tenure, Grant achieved many significant milestones.

For instance, during Reconstruction, Grant cooperated with the Radical Republicans with the sole aim of protecting the Black community. He also worked hard to reestablish the public credit and in the rebuilding of the U.S. Navy, which lagged behind other powerful navies in the world, such as Spain. Born and raised in Ohio, Ulysses Grant possessed exceptional skills and could handle horses incredibly well. This skill helped him a lot throughout his military career. Unfortunately, Grant’s entire presidential run was marred by corruption rumors. He couldn’t stop the great depression of the late 1880s, which resulted in making many people bankrupt, including Ulysses Grant himself.

Joe Biden IQ Score: 124

Joe Biden is the newly elected president of the United States. Biden has a Bachelor of Arts degree from the University of Delaware. The U.S.’s 46th president is a double major in History and Political Science and later earned a law degree from Syracuse University. However, he wasn’t one of the brightest students in the class and was even suspected of indulging in plagiarism in college. He chose to focus more on his political career and didn’t work much in the private sector. Therefore, there aren’t many achievements of Biden to measure his skill level.

In fact, Biden has spent almost half a century in politics. Biden faced one of the worst tragedies of anyone’s life when his first wife and two of his four kids, an infant daughter and an adult son Beau, died of brain cancer. Joe Biden has served as a civil servant since 1972. He is the 5th youngest U.S. Senator in the U.S. history and the longest-serving Senator for Delaware.

George W. Bush – IQ Score: 124.88

George W Bush is the 2nd son of a U.S. President to occupy the Oval Office. John Quincy Adams was the first such president, who became the president in 1825. Presidency seems to be a tradition that runs in the Bush family. Another rule is sending kids to a boarding school. So, following this tradition, George Bush was also sent to a boarding school. However, initially, his academic career was quite challenging. In many of his interviews, Bush narrated how a straight C-student eventually became one of the most successful presidents in U.S. history.

As a president, Bush’s biggest challenge was addressing terrorism. It was during his regime when the unfortunate attack on the World Trade Center occurred, an incident commonly referred to as 9/11. In response to the terrorist attacks in September, Bush established the Department of Homeland Security in 2001 and initiated the War on Terror in Afghanistan. he also signed the much controversial Patriot Act and made it into law. The Patriot Act allowed surveillance of suspected terrorists.

In modern times, President George Bush’s first term is regarded as the most consequential in the U.S. history. The U.S., along with its coalition partners, launched the war against global terrorism. Still, he received immense criticism over the Iraq War and his administrative actions during the devastating Hurricane Katrina. Bush had to deal with mean memes, endless jokes, and media trials throughout his tenure, but he never complained about it.

(tie) Andrew Johnson – IQ score: 125.65

Andrew Johnson was the seventeenth U.S. President who led the nation from 1865 to 1869. Johnson was born and raised in a lower-middle-class household and, therefore, couldn’t afford to receive formal education and became a tailor. Luckily, he got married to Eliza, the daughter of a famous shoemaker, who was well-educated and helped him learn mathematics and improve his writing skills. However, he still wasn’t as skilled to make a favorable and lasting decision as a president. Before becoming the president, Johnson occupied several key positions, including the Governor of Tennessee. Johnson was a Democrat who supported states’ rights and was the only Southern Senator during the Civil War who remained loyal to the Union Army.

After Abraham Lincoln was assassinated, Johnson became the president, an incident that occurred just six weeks after he was inaugurated as the Vice President. John was the first president in the U.S. to be impeached, and his policies sharply contrasted those of his predecessor. Johnson allowed Southern states to create their civil governments, due to which many freed slaves lost most of their civil liberties. Johnson also opposed the provision of rights for African-Americans. His presidential tenure is regarded as among the worst in American history.

 (tie) Zachary Taylor – IQ score: 125.65

Zachary Taylor isn’t the smartest president on this list. However, we do believe that he was an interesting study. Taylor was revered by the public and declared a National War Hero as he played a key role in battles like the Mexican War. He served in the U.S. Army for about four decades before becoming the 12th president of America in 1849. During his tenure, slavery and Southern secession were the most prominent national issues.

Zachary Taylor led the troops against Native Americans and studied the main elements of their warfare style as well as how to defeat the competition. Taylor served as the commander of U.S. troops in five battles, including the Mexican-American War, and won all five. He was a courageous soldier who defied orders and pushed the undefeated forces to as far south as Mexico.

As much as Taylor’s career in the military was successful, his brief presidency was beset with various problems. The most perplexing of them was the controversial issue of extending slavery into the newly acquired Mexican areas. It wouldn’t be wrong to state that he was elected because of his successes as the commander. However, as a president, he couldn’t deliver much. One reason could be that he was in office only for sixteen months and died of Cholera. However, in such a short time, Taylor tried his best to keep slavery out of California, Mexico, and Utah’s developing states.

James Buchanan – IQ score: 125.93

James Buchanan was the fifteenth president of America (1857-1861). He started his political career as a Federalist party member. However, being a savvy businessman, he quickly identified that the Federalists had no future. Hence, he chose to become a Democrat. Buchanan is referred to as one of the worst presidents ever to rule America primarily because of his ignorance towards vital issues like the Southern states’ secession, slavery, and most importantly, the establishment of the Confederacy. Historians claim that his ignorance brought America to civil war.

Buchanan was a lawyer and had amazing oratory skills. From 1814 to 1816 he served in the Pennsylvania legislature, from 1821 and 1831 in the House of Representatives, and in the U.S. Senate from 1834 to 1845. Buchanan was also part of Andrew Jackson’s presidential administration. He was a talented politician with incredible professional integrity and skills.

Buchanan had immense legal knowledge and was apt at balancing differing coalition agendas. If his presidential tenure wasn’t marred with so many complex issues, he might have become the most successful president of the U.S. The problem with the era was that there were too many forces trying to tear the country apart during the late 1850s.

Andrew Jackson – IQ score: 126.25

The early-to-mid-1850s was a difficult period for America. It was the most troubled time in U.S. history. Andrew Jackson, the 7th president of America, and his successor James Buchanan became presidents during this turbulent time and had to deal with various controversial issues. Jackson’s presidential tenure is a lesson for all politicians as it is an example of how bad decisions keep haunting us even after we are gone.

Jackson was a wealthy plantation farmer and commanded troops during several key conflicts, and based on his recurrent military successes. He is mostly remembered as a president who supported slavery and opposes the abolitionist movement. However, historians’ views on Jackson were quite positive in comparison to other presidents during that time. That’s because he promoted democratic principles. One of Jackson’s most memorable achievements, something that no other president could achieve after him, was that he paid off the national debt completely.

Jackson is fondly remembered as the people’s president. There are several remarkable achievements of Andrew Jackson apart from making Americans a debt-free nation. Such ass he destroyed the Second Bank of the United States, laid the foundation of the Democratic Party, supported institutional policies and individual liberty, which forced the Native Americans to migrate.

William Howard Taft – IQ score: 126.9

William Howard Taft is the best example of the importance of work ethics, honesty, and dedication. Taft achieved so much during his tenure (1909-1913), which many other presidents couldn’t. When he was a student, his teachers didn’t think that he would go far in his career as he wasn’t too brilliant. However, his parents always motivated Taft and pushed him to improve and excel in whatever field he chose. That’s why Taft was able to emerge as a topper in law school and finished second in a class of 121 students. Later on, he developed a greater interest in working as a lawyer. Taft served as a lawyer, local and federal judge, the U.S. solicitor general, and the U.S. secretary of war. He was the 27th president of the United States and served only one term. However, he later occupied another pivotal position in the country, the Chief Justice of America. His presidential tenure is remembered for his trust-busting efforts, empowering the Interstate Commerce Commission to determine railroad rates, supporting constitutional amendments to mandate a federal income tax, and enabling people to elect the senators directly. Through his reforms, Taft managed to address progressive democratic, economic, and social welfare goals.

Gerald Ford – IQ score: 127

Gerald Ford, the 38th president of America, was all set to go to law school soon after completing his bachelor’s. However, due to his impressive career in college-level football, many NFL teams offered him lucrative contracts. Nonetheless, Gerald Ford decided to study law, and law remained his first and foremost priority. He also worked as an assistant football coach.

Ford’s vice presidency was full of scandals and controversies. He was roped in after Vice President Spiro Agnew resigned. And when President Richard Nixon also resigned, Ford stepped up and occupied the position. He served as the American president between 1974 and 1977. That particular phase of American history was marked with rising inflation, unemployment, and the Vietnam War. It was a challenging era, and along with that, Ford experienced assassination attempts not once but twice.

It is a fact that despite inheriting a plethora of challenges, Ford remained as upright, honest, and straightforward as he was before becoming the president. He was a staunch supporter of equal rights to all and worked for promoting education for children with special needs. Gerald Ford remained the president for 895 days, which is the shortest duration for a president who didn’t die in office in American history. Some of his notable achievements as a president include signing the Helsinki Accords, cutting the inflation rate by half, and getting nearly 4 million people employed.

Calvin Coolidge – IQ score: 127.1

The 30th president of America, Calvin Coolidge, was a man of few words. He believed in acting rather than speaking, and many even referred to him as the Silent Cal. Coolidge believed that “The words of a president have an enormous weight and ought not to be used indiscriminately.” Coolidge served America as president between 1923 and 1929. He was a conservative Republican who believed in limiting the scope and size of the federal government. Coolidge was among the most progressive presidents as he fully supported the Suffrage movement.

After becoming the president, Coolidge immediately implemented measures to reduce taxes and federal spending. He is one of the few presidents who left office with a budget deficit and smaller national debt than his predecessors. One of the most significant achievements of Coolidge was the signing of the Immigration Act. Through this act, he imposed restrictions on immigrants from southern and eastern Europe. When America dealt with economic issues, Coolidge made significant tax changes to boost the economy, supported racial equality, and brought together the nation. He is still counted among the few very popular presidents in America.

Harry Truman – IQ score: 127.55

Harry Truman was America’s 33rd president. He remained in the office from 1945 to 1953. An interesting fact is that president Truman never got a college degree and was blind in one eye. His path to the presidency was rather unconventional. He cheated in a vision test to enter the military. After his troops achieved consecutive successes in World War I, the countrymen noticed the amazing leadership qualities that he possessed.

Truman served as the vice president for President Franklin Roosevelt in 1945 for just 82 days. After the demise of Roosevelt, Truman took office. He wasn’t too experienced in political or foreign relations, but historians declared his presidential tenure as “near great.” Truman’s policies were entirely different from Roosevelt’s as he implemented an internationalist foreign policy.

The most impactful event that occurred during Truman’s presidency was the atomic bombing against Japan. In fact, Truman was the one who decided to use the atomic bomb to end World War II. Then he also helped in the rebuilding of Europe after the war was over. His role in the downfall of the Soviet Union cannot be neglected. His foreign policy helped American counter Soviet actions successfully. It wouldn’t be wrong to claim that the Truman Doctrine set the framework of how the U.S. should conduct itself in the post-war world.

Lyndon B. Johnson – IQ score: 127.83

When Lyndon B. Johnson, fondly remembered as LBJ, was just 12-years-old when he declared that he would become America’s president one day. LBJ dreamed big, as he had seen his parents struggle to make ends meet and closely experienced how inflation affected low-income households. Johnson wanted to become successful and worked tirelessly to achieve his goals.

His primary goal was to enter the White House and occupy the country’s most influential president position. However, the circumstances under which LBJ managed to achieve his goal were anything but normal. He was sworn in as the country’s 36th president after the assassination of John F. Kennedy.

After becoming the president, LBJ launched an ambitious array of progressive reforms to create a Great Society for the nation. He developed programs that had a lasting impact on the American health care, economic, and education sector. He launched programs like Head Start and Medicare and signed the Civil Rights Act and the Voting Rights Act. However, despite several remarkable achievements, his legacy was marred by LBJ’s inability to lead the nation out of the Vietnam War quagmire. He decided to retire in 1969 after serving one term.

Herbert Hoover – IQ Score: 129.78

Herbert Hoover had a flair for business management from the beginning. He couldn’t get into Stanford, something that he regretted. Hoover had studied geology at school and managed football and baseball teams. He also did laundry for fellow students as a side business. After finishing college, Herbert Hoover started working as a mining engineer in Australia. He was involved in the country’s gold mining industry as a financier, investor, speculator, and mining-related developmental works manager. He also delivered lectures at Universities. Many of you must have heard about the Hoover Institution, the conservative research organization. Interestingly, it was founded by Hoover as a library. Today it is an influential organization that strongly promotes conservative ideology. Through his gold mining business, Hoover became quite rich and earned worldwide fame.

Although a successful businessman, Hoover wasn’t a successful president. The 31st president of the U.S. was an unpopular public figure. He occupied the office during 1929-1933 when America was going through the Great Depression. We cannot blame him for the country’s devastating economic condition back in 1929 when the financial crisis broke out. Yet, his legacy as a president is linked with it.

Ronald Reagan – IQ Score: 130

Ronald Reagan once said that his parents always taught him to remain impartial when making decisions, always be good to others, and maintain a sense of faith. Reagan was the 40th president of America and remained in office from 1981 to 1989. His road to the White House was very unusual as he first earned success and fame as an actor and then became the president. Reagan was the president of the Screen Actors Guild and worked for General Motors as a motivational speaker. Reagan served two terms as the governor of California and tried his luck for the presidency several times before winning the office in 1981. Even though many of his policies were criticized, he stayed true to his values. He left the office with a massive 68% approval rating, which is the highest ever rating for a departing president in recent times.

Some of the notable achievements of president Ronald Reagan include cutting domestic discretionary spending and taxes, increasing military spending, and taking on the public-sector labor unions. He survived one assassination attempt and also stimulated the War on Drugs. The main pillars of his economic policy were the reduction in government spending, drop in the federal income tax, reduction in government regulation and capital gains tax, and tightening of the money supply to decrease the rate of inflation. His economic policy was nicknamed Reaganomics. There’s no doubt that even after so many years, Ronald Reagan continues to be one of the most popular and loved presidents in America’s history.

George H.W. Bush – IQ Score: 130.13

The 41st president George H.W. Bush studied in Ivy League school. Before graduating from Yale University’s enhanced program with a BA in economics, he served the Navy.

William McKinley – IQ Score: 130.18

William McKinley, the 25th president of America from 1897-1901, served as the subordinate of Rutherford B. Hayes during the Civil War. Interestingly, both of them eventually became the presidents of the country. If anyone wants to brush up on networking or mentorship skills, McKinley and Hayes are the perfect case studies. McKinley’s presidential tenure was quite successful, mainly because he had the full support of Hayes.

McKinley inherited a thriving economy. He initiated and ultimately won the Spanish-American War, which historians claim is the hallmark of his tenure. A significant achievement of William McKinley as president was gaining Guan, Puerto Rico, and the Philippines. McKinley also signed a resolution to annex Hawaii to the USA. McKinley’s primary focus during his presidency remained on the expansion of American industry, and he supported an increase in protective tariffs, the result of which was the Dingley Tariff Act. He also promoted the gold standard and rejected the expansionary free silver monetary policy. He advocated for Sound Money and believed that higher tariffs would help in restoring prosperity. McKinley strongly denounced class warfare advocates like Bryan, his opponent in the 1900 presidential election, and defeated him to occupy the presidency for another term.

James K. Polk – IQ Score: 130.2

The 11th president of the United States, James K. Polk, occupied the office from 1845 to 1849. He is known for adopting the strictest work ethics and was widely praised for his dedicated efforts. However, one thing that cannot be ignored is that he compromised his social life and personal health to achieve success. Polk was an extremely hard-working individual and one of the most impactful, effective, and influential presidents of the time. James Pol fulfilled every major policy promise he made to the public and prepared the nation to become a world power.

James K. Polk is known for expanding the U.S. territories via the Mexican-American War. He was the youngest successful candidate for the presidency during that time. In fact, throughout his presidency, the U.S. underwent massive territorial expansion with the Republic of Texas’s annexation, the Mexican Cession after American won the war, and the Oregon Territory. It would be fair to state that James Polk achieved enough success to last several lifetimes during his presidential tenure. He died only three months after exiting the White House.

Polk’s life and career are the perfect examples of how to balance work and life. He chose his cabinet minister wisely and employed a diplomatic approach in every aspect of running a government. He wrote once that all his efforts were driven towards compensating for the fact that he once was “the meager boy, with pallid cheeks, oppressed and worn with disease.”

Grover Cleveland – IQ Score: 130.95

Grover Cleveland was the 22nd and 24th president of the United States of America. His dedication towards making the country a better place was seen throughout both his terms as President.

His determination towards success could be seen when he could not afford college but could pass the Bar by studying on his own. He then went on to start his firm after working three years for someone else’s law firm.

He joined politics and soon became the mayor of Buffalo, New York, and later won the elections as Governor of New York. In the first four years of his presidential term, Cleveland was beloved by many. However, he still fell short during his second election and could not stay in office because of his campaign issues.

Compared to the other Presidents of hi generation, George Washington did not have an academic upbringing as he did not have any education further than elementary school. He still however became the first president of the United States in 1789 despite the fact that records have shown that he took the position with resistant as he just wanted to be a private individual after the American Revolution was fought and the colonies kicked out the King George and the British army.

This achievement proves that people do not need to have a degree to create history. He had an unfortunate childhood; his father passed away when he was in school; his family was poverty stricken, so he had to drop out of school to help out. However, Washinton was an intelligent kid; he had great knowledge of mathematics, drafting, making maps, and surveying, which ultimately led him to become a colonial surveyor at just seventeen years of age. He got a job at the colonial military, where he spent six years. He helped draft maps for the military at times of war with the French and Indians.

Franklin Pierce – IQ Score: 134.78

Pierce had a pretty easy life; his father was the military leader during the Revolutionary War, and that brought many benefits for his family and him. It was almost like he was a celebrity in New Hampshire. His family background easily got him into politics, which eventually led him to become the USA’s 14th president.

He did not earn a good reputation during his term. He did not live up to the people’s expectations, and historians refer to him as one of the worst presidents today. He had good intentions because he built up accountability in government sectors and wanted to start building railroads.  However, his achievements were overshadowed by initiatives that weren’t so liked by people.

However, he wasn’t just smart; he was a fighter. He fought with chronic illnesses throughout his life and never even thought about giving up or giving in. John F. Kennedy attended Princeton University for a short time but left Princeton due to his illness. Kennedy was reportedly a below-average student and was more interested in games and sports.

Donald J. Trump – IQ score: 156 (reported & self-proclaimed); ~125 (estimated)

Many articles have estimated Donald Trump’s I.Q. to be 156, making him smarter than almost 99 percent of the population. In fact this would make him the second smartest President in U.S. history. However, these are false claims and highly inaccurate reporting about one of the United States’ most controversial presidents in modern times. Trump’s I.Q. realistically ranges between 120-130.

Donald Trump is a graduate of the prestigious Wharton Business School at the University of Pennsylvania. However, he didn’t get an MBA degree, something that’s the USP of Wharton, but he earned a Bachelor of Science degree in Economics and Anthropology. An interesting fact is that Trump didn’t go through the normal admission procedure and was transferred to Wharton from the main university during his first year at Wharton. The admission conditions for such candidates are not as rigorous.

But, let’s not jump over to conclusions because not having a Wharton MBA degree doesn’t mean Trump is dumb. We cannot overlook the fact that Trump graduated from the University of Pennsylvania, which is an Ivy League school. Trump never shared his High School or College-related information, as he didn’t prepare the Dean’s List, which is why it is difficult to determine how he ended up at Wharton. What we do know is that he didn’t graduate with any honors. According to one of his classmates, Trump “was not first in the class. He was not known on campus for any reason at all. I have no memory of him whatsoever.”

John Quincy Adams – IQ Score: 168.75 (Highest)

John Quincy Adams is the most intelligent president of the U.S. ever. Adams was the 6th president of the U.S. between 1825 and 1829.

When he was studying at Harvard, he became romantically involved with a local female, a union that his parents opposed so that he focuses on his career. Adams did listen to their advice and eventually became the president of the country. Historians state that he is one of the country’s most productive presidents as he possessed exceptional diplomatic skills. With his efforts, the Treat of Ghent was settled, and the War of 1812 came to an end. He also purchased Florida from Spain.
