The IQs Of All Of Your Favorite U.S. Presidents

The President of the United States is supposed to be a brilliant leader, evaluator, diplomat, and economist. But, are the presidents really all that smart? Here are your favorite presidents’ IQs based on a variety of studies that have been conducted over the years. These studies make estimates on a number of factors including previously published assessments of IQ as well as intellectual brilliance and openness to experience, both believed to be important to intelligence.

Calvin Coolidge

Calvin Coolidge first started out of a lawyer in Massachusetts and became the governor of the state. Coolidge was a quiet man, and he was also one of the smartest people who set foot in the White House.

Someone visiting the White House bet Coolidge he could make Coolidge say more than two words. Coolidge simply responded to the better, “You Lose.” Even though many people thought Coolidge was stupid because he was quiet, he was actually just soft-spoken and very thoughtful. His IQ is estimated to have been a perfect 130, meaning he wasn’t at genius level, but he was almost there.

Ronald Reagan

Ronald Reagan is known famously for being the poster child and president for the Republican party. His presidency focused heavily on his brain child, which was labeled “Reaganomics.” His economic policy focused on a tax rate reduction, control of money supply, and reduction in government spending. He also ended the Cold War with Russia and tore down the Berlin Wall to eliminate the USSR.

Ronald Reagan is one of the most well-loved presidents in the modern era and had one of the highest approval ratings. At the end of his administration, Ronald Reagan’s approval rating was a shocking sixty-eight percent, which was the same as Franklin D. Roosevelt and Bill Clinton. Well, who wouldn’t like the guy who has a 131.9 IQ?

Richard Nixon


Richard Nixon had many devoted fans, but was also one of the most disliked presidents of all time. Richard Nixon is best remembered for his involvement in the Watergate scandal, when he and other Republicans hacked into the Democratic headquarters located at the Watergate hotel in Washington D.C.

Nixon focused heavily on trying to end the space race in the 1970s which was part of the heavily intense time called the Cold War. The Space Race was an attempt by the United States to reach the moon first and to venture out into space before the Russians. Nixon made it his mission to limit funding for the Space Administration, even though his IQ was a high 132.6.

George W. Bush

The Yale-educated man was the second son to become the American president after his father, with the first having been John Quincy Adams. Bush, the 43rd president, served from January 20, 2001 – January 20, 2009. He holds the interesting distinction of ranking among the most popular and the most unpopular of all the U.S. presidents in history.

Bush’s IQ is likely somewhere around 139, according to an analysis of factors.

George Washington

George Washington was the first president of the United States and is known today for being an amazing battle strategist. He is credited with the thought behind the Battle of Yorktown and with the win of the American Revolution. But, what was his IQ?

When it comes to IQs, there are some numbers which you should know. Anything above 140 is considered a genius, while anything between 120 and 140 is said to belong to a person with superior knowledge. Washington’s IQ is said to have fallen at around 140, based on historical views, meaning he was quite the smarty.

Lyndon Johnson

Some people loved Lyndon Johnson and some people absolutely despised Lyndon Johnson, but that’s just how the 1960s were. Johnson was the president in power during the tumultuous Vietnam war and escalated the United State’s involvement. The Vietnam War is still a sore spot for many Americans who have polarizing views on the subject.

Lyndon B. Johnson, or LBJ, assumed the role of president after JFK’s tragic death. LBJ was in favor of a law-and-order type of view on crime. Some experts have estimated Johnson’s IQ to be somewhere right around 140.

Abraham Lincoln

Abraham Lincoln is one of the most well thought of and respected presidents. He is considered the ultimate abolitionist and the reason for the end of slavery. Abraham Lincoln’s free thinking and revolutionary ideas proved he had some smarts about him.

Abraham Lincoln’s intelligence is not only proven by what he did in his presidency but also his capabilities to fight for what he wants. Abraham Lincoln failed the bar exam and even worked as a boat man before landing a law job. Lincoln was shot too soon before proving what he could do with his 140 IQ level.

George H. W. Bush

The late father of George W. Bush made quite a name for himself and the rest of the new and reformed Republican party. Bush Sr. and his administration made a deficit in the United State’s economy by increasing taxes for the working class. This went against Republican values, and was a huge loss for Bush.

The economy under Bush went into a growing recession which prompted voters to vote for Bill Clinton in the 1992 election. Even though Bush’s IQ was allegedly around 143, it didn’t help his presidency.

Teddy Roosevelt

Theodore Roosevelt served as the 26th president of the United States and is still remembered for his wise words and sayings. Teddy Roosevelt is known for breaking up the trusts and monopolies of the railroad companies to help working-class citizens. He is also recognized for perfecting and preserving thousands of acres of land for national parks around the country.

Andrew Jackson

Andrew Johnson, the 17th president of the United States, served from 1865 to 1869. He was vice president at the time of the assassination of Abraham Lincoln.

Andrew Jackson was born poor and he had always thought of the government as being corrupt. This is why one of his policies was an investigation into the corruption of the government and the “witch hunt” of Cabinet offices and departments. His estimated IQ is a high number — 145.


FDR, or Franklin Delano Roosevelt, is considered the genius behind modern economics and the recreation of the American economy after the Great Depression. FDR’s biggest claim to fame is his New Deal, which created public jobs, like the Empire State Building and Tennessee Valley Authority to give working-class Americans jobs. FDR also repealed prohibition, which many can thank him for!

Although his presidency was marked by controversy, Clinton is remembered for signing the Family and Medical Leave Act of 1993, and also for leading a policy of fiscal conservatism that helped to reduce the deficit.
