The Most Intelligent US Presidents and Their IQ Ratings

Bill Clinton

It appears that men possessing high intelligence quotients tend to show a propensity for unfaithfulness, as was clearly exhibited by Bill Clinton in one of the most notorious scandals in White House history.

Even though he possessed an impressive IQ of 159, he still found himself at the mercy of media scrutiny and public opinion. He attempted to refute the rumors of his clandestine affair with Monica Lewinsky, stating, “I did not have sexual relations with that woman.” Yet, Clinton’s towering intellect was not enough to fabricate a credible lie. In addition to the adulterous scandal, he also managed to misplace the nuclear launch codes for several months. It leaves us speechless.

Warren G. Harding

Warren Harding was notably one of the most celebrated presidents in the annals of American history. Nonetheless, his repute took a significant hit due to his association with ‘The Teapot Dome’ controversy. He caught in strife by permitting private oil corporations to indulge lucratively in oil and gas extraction in Wyoming, and inevitably, a noticeable amount of money streamed through the Presidential enclave. Clearly, he relished each shred of the bounty. Needless to mention, this episode consumed his previously untarnished stature.

Regarding his IQ score of 139.9, what became of it? Harding had a vision of an America where the economy reigned supreme, and wealth accumulated in abundance for the rich. He bolstered the economy while reducing public debt, but his reputation was tainted by scandal and dubious events in the Oval Office.

John F. Kennedy

JFK, reputed as one of America’s most intelligent presidents, boasted a titanic IQ of 159.8, making him extraordinarily remarkable. Not only was he known for delivering one of the most impactful speeches in history, but allegations also portrayed him as quite the charmer with women.

Some of his most renowned romances were with Marilyn Monroe and Jackie O. JFK jokingly described his presidential role saying, “the salary is decent, and the office is a stroll away.” He is most notably remembered for his insightful and thought-provoking quotes and speeches.

Ulysses S. Grant

Bear in mind that the standard Intelligence Quotient (IQ) typically varies from 85 to 115, prior to forming any evaluations. Considering this scale, Grant’s 130 IQ score is rather commendable. Nevertheless, it seemingly did not aid him in uncovering the Whiskey Ring scandal, hidden tax revenue, and various other issues that transpired during his tenure.

Remember, he ascended to become the 18th President of the United States of America, and served as the chief commander of the Union forces in the American Civil War. Even though his IQ score exceeded the average, he often struggled with accurately assessing people’s characters.

James Monroe

James Monroe, one of America’s founding fathers, led the country at a time when internal matters were a significant concern. Although Monroe’s IQ was a moderate 138.6, political scientist Fred Greenstein argued that he was a superior leader compared to some of his intellectually higher-ranking predecessors, such as John Adams.

The administration of Monroe managed to settle numerous problems, actively aiding the Missouri Compromise and bolstering national unity. In the year 1820, Monroe claimed a remarkable triumph over Rufus King from New York in a huge landslide, receiving 183 votes to King’s 34. Without question, he was a president who sparked beneficial reform for the betterment of his citizenry.

George W. Bush

Regrettably, Bush is often perceived as one of the less intellectually impressive American presidents. His performance did not reflect his notable IQ of 138.5.

Despite his reputation for being eloquent, his public speaking abilities were less than stellar and his speeches often didn’t make much sense. His academic record in high school may not have been impressive, but he was outstanding when it came to interacting with others. Surprisingly enough, he even served as the head cheerleader. Can you visualize George W. Bush waving pom-poms?

Andrew Johnson

Abraham Lincoln’s successor assisted the Union, but didn’t express strong support for granting voting rights to emancipated slaves. Johnson made history as the first US president to be impeached, following his implementation of the “black codes”, which suppressed recently liberated slaves. He staunchly objected to laws intended to safeguard these individuals. What a disappointment.

Despite Johnson’s fairly high IQ of 138.9, his thought processes were archaic and filled with prejudice, which was quite a disappointment. The White House made significant attempts to oust him, but unfortunately, couldn’t succeed in doing so. His term as president from 1865 to 1869 resulted in widespread discontent and disillusionment among the citizens.

Zachary Taylor

Cherries are abundant in Vitamin C, yet having an excess can be hazardous. Just look at the experience of Zachary Taylor, whose presidency was abruptly terminated following an overindulgence in these small red fruits during a 4th of July festivity in 1850.

Taylor’s indulgence certainly appears to have been his undoing – it led to his demise just 16 months into his presidency. His reputation is marked by his bravery during the Mexican-American War, yet neither his considerably high IQ of 139.8 nor his distinguished gallantry could shield him from the detrimental effects of overindulging in cherries.

James Buchanan

Despite James Buchanan’s impressive IQ of 139.6, his intellectual capability didn’t assist him in his presidential tenure. He failed to demonstrate the necessary insight and comprehension to resolve the conflict over slavery. His support for Dred Scott won him favor among the Southerners, but it enraged the Northerners, causing a chain reaction that ultimately led him to split his own party.

The 15th President of the United States, recognized for his role during the Civil War, was Buchanan. Regrettably, Buchanan was unsuccessful in romance, being the only President who remained unmarried throughout his life, thus maintaining the unique distinction as the strongest leader of the nation to stay a bachelor.

Andrew Jackson

Boasting an impressive intellectual quotient of 145, Andrew Jackson held a deep trust in the judgment of the “average person” to make the correct choices. His life aptly manifested the old adage that “what doesn’t kill you makes you stronger”, as he once endured a severe injury from a gunshot in the chest during a duel. Furthermore, Jackson utilized his high IQ in an interesting way – he dedicated considerable time teaching his pet parrot, Polly, to curse. In fact, the bird became so proficient in foul language that it had to be taken out from Jackson’s funeral due to its profanity.

William Howard Taft

Get to know William Howard Taft, the 27th U.S. President, boasting an IQ of 139.5. His resume not only includes presidential duties but also the position of Chief Justice, making him the sole individual to occupy both roles.

This extraordinary individual exemplified his IQ in the realm of politics, but also showed creativity by designing a customized bathtub that could fit four individuals of average size. Still, Taft didn’t seem particularly thrilled with his presidential duties. He once wrote, “I don’t recall ever being President.”

Gerald Ford

Serving as the 38th president of the United States, Ford boasted an impressive IQ of 140.4. He assumed the presidential role without being elected, a historic first, following Nixon’s resignation amid the notorious Watergate scandal. Even though his administration has often been met with indifference, it’s worth noting that Ford’s efforts aimed to restore faith among Americans after the Watergate debacle.

Apart from his commendable intelligence, Ford was one of the most illustrious sporting figures to occupy the Oval Office. His years spent engaging in football and skiing helped maintain his vigor and agility.

Calvin Coolidge

The 30th American president, Calvin Coolidge, boasted an impressive IQ of 141.6. Even though he was known for his reserved nature, his contributions to the United States were far from insignificant. Following the problematic tenure of President Harding, Coolidge stepped in as the ‘fixer’ and the advocate for middle-class citizens, helping to restore the nation’s belief in its government. He tidied up a great deal of chaos during his reign, which led to considerable public admiration by the end of his term.

This man earned his nickname “Silent Cal” for being laconic. A widely shared anecdote tells of a time when a woman seated next to Coolidge at a dinner party challenged him, saying, “I wagered today that I could coax you into speaking more than two words.” Coolidge’s unruffled response was, “You lose.” What a smooth riposte.

Harry S. Truman

Harry S. Truman, who was known for his assertiveness, served as President during significant periods of conflict, including World War II and the onset of the Cold War. He barely held the position of Vice President for a few weeks before he had to step up to the highest office due to Roosevelt’s unfortunate passing. Truman once confessed to journalists that he felt as if “the moon, the stars, and all the planets had fallen on me.”

During his tenure, Truman employed his impressive IQ of 139.8 to address issues concerning the A-bomb’s creation and escalating complexities with the Soviets. Truman’s authorization to drop atomic bombs on Hiroshima and Nagasaki marked one of the most critical junctures in American history.

Lyndon B. Johnson

Lyndon B. Johnson, who succeeded JFK, undoubtedly had a challenging role to step into. While his performance may not have lived up to some expectations, there is no denying his substantial and contentious impact on the history of American presidency.

There’s no denying that his intelligence quotient of 140.6 played a role in his choice to amplify America’s military involvement in Vietnam. Maybe seeking advice from Woodrow Wilson before endorsing such a move would have been wise. On a less serious note, Johnson was infamous for his unrepentant ‘bathroom interviews,’ ensuring that no reporter could interrupt his personal time. He also has a reported history of relieving himself in the White House’s parking lot.

Herbert Hoover

During Herbert Hoover’s presidency, he faced the devastating stock-market crash of 1929. Despite having an impressive IQ of 141.6, running the country during such a time was tremendously challenging. By the end of the decade, his popularity had dramatically declined as numerous Americans had lost their employment and homes.

The United States was in dire need of a leader capable of lifting them from the depths of the Depression, yet they were stuck with a man of little value. Hoover was at fault for withholding much-needed aid from distressed Americans, all under the guise of capitalism. Many Americans viewed Hoover’s time in office as a grim period of letdown and difficulty.

Ronald Reagan

Ronald Reagan, who served as the 40th U.S. president, held office for two terms. Prior to his presidency, he had a career as an actor and has reportedly had an IQ score of 141.9, which is considered average for individuals who have held presidential roles. His noteworthy campaign slogan, “peace through strength,” generated anticipation among citizens that he would fulfill his promise of restoring the “confident roar of American progress and growth.”

Nevertheless, the 1980s Iran Arms Scandal tarnished his esteemed reputation. Despite his initial denial of entering any transaction, he eventually confessed to trading missiles with Iran to secure the release of American captives. It’s incomprehensible how he disregarded the wellbeing of innocent people by dealing arms with a terrorist organization.

George H.W. Bush

If it’s true that the apple doesn’t fall far from the tree, then how would George H.W. Bush interpret his son’s leadership style? The first Bush might not be considered the most intellectually superior in the White House, but his achievements were indeed noteworthy.

Possessing an intelligence quotient of 143, Bush’s leadership approach aimed at transforming the United States into a more compassionate and milder nation. He also displayed his robust leadership by successfully tackling various problems, including Saddam Hussein’s attack on Kuwait and the turmoil in Cuba. Despite these efforts, however, they were insufficient to prevent his ousting from the White House.

William McKinley

Making an appearance on our roster is the United States’ 25th President, William McKinley, commanding our admiration with his impressive IQ of 143.4.

McKinley’s endorsement of the gold standard and his subsequent election into office revitalized the American economy. Under his management, industrial growth accelerated, eventually bringing an end to the Depression of the 1890s. Tragically, McKinley became the third U.S. president to be assassinated. His untimely demise prompted Congress to pass legislation charging the Secret Service with the responsibility of safeguarding the president.

James K. Polk

James K. Polk shares an identical IQ score of 143.4 with McKinley. Polk was regarded as one of the most effective leaders in the era prior to the Civil War. Even though he was viewed as an unlikely contender in the race for presidency, Polk proved to be an excellent choice. He initiated significant transformations in the United States through his handling of territorial conflicts, financial strategy, and banking affairs.

He broadened the boundaries of America, maintained peace with the United Kingdom, and was victorious in the Mexican-American War. Polk kept to his campaign vow of serving just a single term as president due to health deteriorations brought on by the strains of leading. It’s worth noting that a superior intelligence quotient does not necessarily equate to a strong ability to withstand severe stress and pressure.

Grover Cleveland

Grover Cleveland, an intriguing figure, once resided in the White House. With an impressive intelligence quotient of 144, it was quite remarkable that he was elected on two occasions. However, his term was not devoid of controversy.

Why does it seem as though IQ and controversy are so intertwined? Would you consider marrying your own daughter? If your immediate reaction is a firm “no,” we’re in agreement. However, this wasn’t an issue for Cleveland. He wed his 21-year-old daughter, whom he’d adopted when she was just 11. This made her the youngest first lady ever in history.

Richard Nixon

Richard Nixon is often considered one of the most contentious U.S presidents. Notwithstanding his significantly high IQ of 142.9, his presidency testifies to the fact that intelligence does not automatically lead to successful leadership in the Oval Office. He reportedly planned to murder a journalist who threatened to uncover his role in the notorious Watergate scandal by overly exposing him to LSD. Subsequent investigations into the Watergate scandal confirmed a direct link between Nixon and the intruders.

As a result, 69 government officials were accused, and a lot of individuals closest to Nixon fell. What about Nixon? He took necessary steps to escape impeachment, which involved stepping down from office in 1974.

Dwight Eisenhower

Dwight Eisenhower, known as the 34th American president, holds a cherished place in United States historical lore due to his immense popularity. The impressive IQ of 145.1 he boasted further uplifts his stature. Eisenhower’s widespread accomplishments, novel initiatives like founding NASA and the establishment of interstate highways, are a testament to his effective deployment of intelligence. Beyond his politic endeavors, he also expressed his talents as an ardent golfer and a dedicated artist, having produced more than 250 pieces of artwork during his lifetime.

The only issue he encountered within the confines of the White House was with the local squirrels. He was so aggravated by these animals that he demanded they be exterminated. Contrarily, the Secret Service, in a discreet alliance with the landscape maintenance team, devised a plan to capture and set free the squirrels in Rock Creek Park.

Benjamin Harrison

Sometimes referred to as “Little Ben” because of his noticeable lack of height, Benjamin Harrison served as the 23rd President of the United States. Despite his small stature, make no mistake about his influence – Harrison was instrumental in forming US foreign policy. Nevertheless, this witty man was plagued by a peculiar fear. Electricity was the sole factor that unsettled Mr. Harrison.

Even with his apprehensions, his presidential tenure facilitated progress in electrical conduction. Harrison was the one to suggest setting up electric lighting in the White House. Interestingly, despite this bold move, he was too afraid of the electricity flowing through them to actually switch the lights on himself.

George Washington

Introducing Sir George Washington, the inaugural President of the United States, who was gifted with an impressive IQ of 140. He is primarily known for his extraordinary military successes and his remarkable talent of taking over the dance floor.

Washington was also in charge of one of America’s most significant distilleries during his time. After his presidency, Washington found his time at his Mount Vernon residence quite mundane and hence opted to venture into the liquor industry, managing to produce 11,000 gallons of raw whiskey. Who knew he possessed such remarkable ability in the alcohol industry!

Martin Van Buren

Van Buren, the 8th US President, is known as the architect of the Democratic Party. Despite his impressive IQ of 146, he didn’t demonstrate the exceptional policymaking and exceptional leadership often associated with such intelligence. Earning the unflattering nickname “Martin Van Ruin” reveals much about his unsuccessful term. His successor, William Henry Harrison, didn’t fare much better. Both Van Buren and Harrison may have had commendable intellectual prowess, but their political contributions were lackluster, leaving the nation and its citizens profoundly disappointed.

Rutherford B. Hayes

An alternative “unexpected” contender is Rutherford B. Hayes, who is mostly recognized for his election rather than his tenure. It raises questions as to why he didn’t accomplish more, given his impressive IQ of 146.3. In 1876, Hayes emerged as a champion of the Civil War. Despite votes leaning towards Democrat Samuel Tilden, Hayes found himself lagging in the electoral vote. However, due to a loophole in the Constitution, he technically won the presidency. While he doesn’t receive much attention in the US, he is highly revered as a national hero in Paraguay.

His negotiations in a border conflict involving Argentina and Paraguay have made him greatly valued by the Paraguayans. The intervention of Hayes led to Paraguay regaining 60% of its territory.

William Henry Harrison

At the age of 67, William Henry Harrison became the oldest man to be elected president at that time, only to become the first American president to pass away while in office. Unfortunately, this is the achievement he is most ubiquitously remembered for. His tenure, cut short due to pneumonia, lasted merely 31 days.

Ironically, the president who served the shortest term gave the longest inaugural speech. Indeed, Harrison spoke for one hour and 45 minutes on a cold morning in March 1841. It is suspected that the extreme cold he experienced that day developed into the severe pneumonia that led to his death.

Franklin Pierce

Despite having an impressively high IQ of 147.4, Franklin Pierce didn’t turn out to be an extraordinary president. His reputation was rather tarnished due to his seeming lack of political capability. His endorsement of the Kansas-Nebraska Act primed the starting pistol for the Civil War, further adding to his negative portrayal.

It has been reiterated that having an exceptionally high IQ doesn’t correspond with exceptional performance in the White House. At this significant juncture in its history, the United States did not require his regressive political ideologies.

James A. Garfield

Even though James Garfield had an impressive IQ of 152.3, his presidency ended prematurely. The legacy left behind by the ex-USA President sadly lacks any noteworthy accomplishments or transformations. His high intelligence only indicated his potential in leadership, had he not been prematurely ousted from power.

Garfield’s service to America only lasted a total of six months and 15 days. Although still a part of the country’s history, one can’t avoid pondering the possibilities had his intelligence been employed more effectively.

John Tyler

John Tyler, who served as the 10th President of the United States, boasted an impressive IQ of 148. He assumed the role following the sudden and fatal term of Harrison. Tyler earned the unofficial nickname of “His Accidency” since there was no designated successor at the time of Harrison’s death. Ever the opportunist, Tyler cleverly arranged for a judge to administer his presidential oath.

His contribution towards incorporating Texas and connecting Florida to the Union stirred up the gradually escalating civil conflict. Ultimately, all Tyler demonstrated was that he was among those intelligent individuals with a distinct inclination towards conflict.

John Adams

John Adams, distinguished as an exceptional political thinker, is recognized for his vital role as America’s second president. As a core contributor to the foundation of the nation, Adams utilized his 155 IQ effectively in the formation of the Constitution. His pivotal role in concluding the Revolutionary War also made a significant impact on the course of US history.

John Quincy Adams, despite his father’s exceptional intelligence, demonstrated that he possessed superior mental and physical prowess. On the other side, John Adams Sr. passed away at the remarkable age of 90.

Millard Fillmore

Possessing an impressive IQ of 149, Millard Filmore unfortunately fell victim to his carnal desires. He grew besotted with Abigail Powers, to the point where he proposed marriage to her, a proposal she happily accepted. Yet it appears his attention was diverted more towards his romantic life rather than the issues of the nation, resulting in his presidential tenure plunging the country into the Civil War.

Similar to other highly intelligent presidents, Fillmore is recalled as one of America’s least successful leaders. Should we delve deeper into this complicated issue?

Franklin D. Roosevelt

There is no question that Franklin D. Roosevelt is among the most revered leaders in American history. The country is significantly indebted to him for his remarkable four-term presidency which was marked with monumental milestones such as his revolutionary “New Deal” reforms, various social initiatives, and his proficient guidance during World War II.

FDR’s remarkable legacy, accentuated by his impressive 150.5 IQ and numerous commendable achievements, can’t be disputed. However, his life wasn’t without controversy. One such scandal involved his wife’s social secretary, Lucy Mercer, with whom he had an extramarital affair, perhaps due to her irresistible charm.

Abraham Lincoln

Abraham Lincoln, with an estimated IQ of 150, was one of the most brilliant individuals of his time. Beyond his intelligence, he was also renowned for his notable achievements. In an era when obtaining an education was challenging, Lincoln’s journey from hardship to a significant political position was indeed extraordinary. His issuance of the Emancipation Proclamation in 1863 resulted in the liberation of numerous enslaved people.

His remarkable intelligence is evident in his Second Inaugural Address, which is also inscribed on the Lincoln Memorial in Washington DC. It states: “Without any ill will; with kindness for everyone; with conviction in the right, as God guides us to understand it, let us continue to carry out our responsibilities…”

Chester Arthur

Chester Arthur, recognized for having an exceptionally high IQ of 152.3, stands out for being one of the most intelligent US Presidents. This elevated IQ measure significantly contributed to his successful career as a lawyer and a public servant. He assumed the presidency after the tragic assassination of James Garfield.

Regrettably, Arthur’s tenure as president did not quite live up to expectations at that time. He appears to be recognized more for his accomplishments prior to his presidency than his time in office.

Theodore Roosevelt

Following the assassination of William McKinley, Theodore Roosevelt, at the tender age of 42, ascended to the presidency, becoming the youngest ever president in U.S. history. Roosevelt’s vigorous policies and charisma exerted a powerful presence in the political landscape.

With an impressive IQ of 153, do you have the courage to take on his intellectual prowess? Here’s a fascinating fact: Theodore Roosevelt was quite the pugilist during his tenure at Harvard University. His love for boxing was such that he carried on with this physical hobby even during his presidential term at the White House. An exemplary combination of superior intellect and excellent physical fitness, wouldn’t you say?

Woodrow Wilson

Introduce yourself to Woodrow Wilson, a pivotal personality who guided the US during the most significant war in global history. Wilson, boasting an astonishing IQ of 155.2, held his position from 1913 to 1921.

He championed global peace and continues to be regarded as one of the most eminent presidents in American history. His renowned “Fourteen Points” peace proposition and his essential involvement in the Treaty of Versailles negotiations have earned him notable recognition in historical records. Undoubtedly, his considerable intellectual capabilities greatly benefited his progressive thinking, competence, and practical method.

Jimmy Carter Jr.

Making the list of the most intelligent U.S. presidents is James Earl Carter, Jr., who is also a Nobel Peace Prize laureate. Boasting an IQ of 156.8, his ambitious aspirations of fostering a capable and empathetic nation were admirable, although arguably unattainable during his era.

He was a strong advocate for human rights, a deed for which we commend him. Yet, his unusually advanced intellect sometimes seemed somewhat bizarre. He professed to have witnessed UFOs following a conference in Georgia in 1976. What’s your take – could there be some truth to his alleged sighting?

James Madison

There’s no way we can overlook James Madison’s inclusion in this list. Acknowledged as the Father of the Constitution, Madison boasted an impressive IQ of 160. In addition, he held the position of Secretary of State during Jefferson’s tenure and made significant contributions that shaped the history of the United States.

Contrary to those who came after him, Madison modestly asserted that the Constitution wasn’t simply “born from a single mind,” but instead was “the product of numerous minds and multiple hands.” Our gratitude towards you, sir, is immeasurable.

Thomas Jefferson

Thomas Jefferson, credited with penning the Declaration of Independence, was one of the smartest American presidents, boasting an IQ of 160. After serving as the Foreign Minister to France, he developed such an appreciation for French food that he compelled his chef, who was only 19 at the time, to master the craft of French culinary arts.

Jefferson was known for throwing extravagant feasts brimming with French cuisine. Beyond his penchant for gourmet food, his high intelligence allowed him to step outside traditional norms and utilize his presidency to make significant positive impacts.

John Quincy Adams

John Quincy Adams clinched the title as the most intelligent President in the history of the United States. Boasting an impressive IQ of 175, he was capable of creating considerable progress. His progressive views on topics of slavery and freedom of expression should forever be acknowledged.

Despite being a notable individual, Adams wasn’t as impactful as he had the potential to be. Even though he was fluent in seven languages and had a highly intellectual mind, his penchant for daily skinny-dipping indulgence took precedence over tending to national concerns.

Barack Obama

Although the exact measure of Obama’s intelligence quotient is not specified, his two-term presidency witnessed considerable transformations. As the first African American President, Barack Obama displayed a unique blend of assertiveness and sensitivity which culminated in the elimination of ruthless terrorists, including Osama bin Laden. Obama relentlessly pursued global peace and the protection of his home country.

To the public, Obama was a welcome change following a series of preceding presidents. His authentic American identity and middle-class background resonated with many, contributing significantly to his efficacy as a leader, independent of his intellectual quotient.
