Did Trump Take a Cognitive Test? Former President Boasted About His IQ

Rep. Ronny Jackson and 13 of his House Republican colleagues are calling on President Joe Biden to undergo the same cognitive test that his predecessor Donald Trump reportedly passed in 2018.

In a letter on Thursday, the 14 GOP representatives cited what they described as Biden's "mental decline and forgetfulness" and urged him to take the Montreal Cognitive Assessment (MOCA).

"We encourage you to follow the example set by President Trump by undergoing a cognitive test as soon as possible and immediately making the results available for the American people," the letter said.

Trump has frequently boasted about his intelligence quotient and criticized others, saying they had low IQ.

On January 6, 2018, Trump famously took to Twitter to declare himself "a very stable genius."

He wrote: "I went from VERY successful businessman, to top T.V. Star […] to President of the United States (on my first try). I think that would qualify as not smart, but genius…and a very stable genius at that!"

However, there was speculation about Trump's mental state throughout his presidency. In 2020, he sought to dismiss questions about his mental fitness by touting the results of a cognitive test.

"I proved I was all there because I aced it. I aced the test," Trump told Fox News' Sean Hannity on July 9, 2020, adding that he had taken the cognitive test at Walter Reed National Medical Center "very recently."

Trump went further, telling Hannity the doctors "were very surprised."

"They said, that's an unbelievable thing. Rarely does anybody do what you just did," he said.

When Trump made the comments to Hannity, it was not immediately clear what test he was referring to or when it had been administered. It later emerged that he was talking about taking MOCA in 2018.

MOCA is not a test of IQ but is designed to assess whether a person has cognitive impairments. The questions appear simple—such as asking the person to draw a clock showing 11.10—but they test for problems that might occur in the early stages of dementia, according to The New York Times.

Trump reportedly scored 30 out of 30 on MOCA but this gives no indication of his intelligence. Mensa, the high IQ society, accepts over 200 different tests to measure IQ, according to BBC News. The former president has never published results from a test measuring his IQ.

Psychiatrists told Newsweek in 2018 that it was important to note what MOCA did not test for.

"The fact that anybody gets a perfect score on the MOCA suggests that they are not having changes in cognitive function associated with early signs of dementia," said Columbia University psychiatrist Dr. Paul Appelbaum.

"It can be very reassuring in that regard. But it's important to recognize that that's all it tells you," Appelbaum said.

Newsweek has asked the office of former President Donald Trump for comment.
