Franklin Pierce – 147.4
The 14th president of the United States was nothing short of a controversial head of state. He called the abolitionist movement “a fundamental threat to the unity of the nation.”Given this, it’s understandable that this Democratic president would sign the Kansas-Nebraska Act. With an IQ of 147.4, Franklin Pierce is just one point above the average president. This act effectively gave each state the power to decide how they felt about slavery.

John Tyler – 148
Following the death of William Henry Harrison, John Tyler became the 10th President of the United States. He was the first president to succeed a president who died in office. To put it another way, he was the first president who was not elected, and he served as the country’s leader from 1841 to 1845. Tyler delegated authority over slavery and a number of other issues to the states. He earned quite a number of enemies in Congress thanks to his passive stance, and he was dubbed “His Accidency.” John Tyler was extremely intelligent, with an IQ of 148. When you consider how long ago he was president, that’s even more impressive. During his term, he was also the subject of the first attempted impeachment, which failed. He negotiated treaties with China and the United Kingdom on international issues.
