Marilyn vos Savant and the Highest IQ in History: When Genius Meets Misunderstanding

In 1985, a name emerged from nowhere: Marilyn vos Savant. Guinness World Records officially recognized her as the holder of the highest IQ in history, with an astonishing score of 228. A number that seemed unimaginable, far above Einstein’s (160-190), Stephen Hawking’s (160), and even Elon Musk’s (155). Yet, this woman destined to represent the pinnacle of human intelligence would soon experience something completely unexpected: being ridiculed worldwide for a seemingly trivial answer.

An extraordinary girl with the highest recorded IQ

At ten years old, Marilyn was not an ordinary girl. She had the ability to memorize entire books. She devoured all 24 volumes of the Encyclopedia Britannica. It was during this prodigious childhood phase that she set the intelligence record that would define her for life.

However, her path to success was not straightforward. She attended a regular public school, where her exceptional abilities did not attract much attention, especially because she was a girl. After two years at the University of Washington, she dropped out to help her family run their business. Life seemed to flow normally until public visibility completely changed her trajectory.

Invitations multiplied: appearances on the covers of prestigious magazines like New York Magazine and Parade Magazine, appearances on David Letterman’s Late Show. For a woman who loved writing, an extraordinary opportunity arose: a weekly column in Parade Magazine called “Ask Marilyn.” It was the dream she could have hoped for. She never imagined that the same space would bring her a storm of worldwide criticism.

The Monty Hall problem: when simple becomes incomprehensible

September 1990. A letter arrives at the editorial office containing a question that seemed almost trivial, addressed to TV host Monty Hall and his famous game show “Let’s Make a Deal.” The question was:

Imagine you’re participating in a TV quiz. In front of you are three closed doors. Behind one is a car, behind the other two are goats. You choose one door, say door number one. The host, who knows what’s behind each door, opens another door, revealing a goat. Now the host asks you: do you want to stick with your original choice or switch doors?

Marilyn’s answer was clear and confident: “Yes, you should switch.” Simply.

The reaction was devastating. Over ten thousand letters arrived. Nearly a thousand came from PhDs and people with advanced academic degrees. And 90% of them were convinced she was completely wrong. The criticisms were ruthless and, in some cases, personal: “You’re really the goat!”, “You were totally wrong, big time!”, and even sexist comments: “Maybe women see math problems differently than men.”

But was she really wrong?

Why 10,000 people were mistaken over a simple probability question

The key to understanding her answer lies in probability. Let’s examine the two possible scenarios:

Scenario 1: Suppose you chose the door with the car (probability: 1 in 3). In this case, the host reveals a goat. If you switch doors, you lose.

Scenario 2: Suppose you chose a door with a goat (probability: 2 in 3). The host is forced to reveal the other goat. If you switch doors, you win definitively.

The probability of winning by switching is therefore 2 in 3, or about 66.7%. Marilyn was right.

Why did so many people, including PhDs, fail to see this? Experts identify several reasons:

First, our brains tend to “reset” the situation when a new choice is presented. Mentally, many see the scene as if it restarts from scratch: two remaining doors, each with a 50% chance. This is a natural but systematic cognitive error.

Second, the small number of options (only three doors) paradoxically makes the problem harder to visualize than amplified versions of the same question. With a hundred doors, the solution would be obvious.

Finally, many simply assumed that each remaining door had a 50% chance of hiding the prize, without delving into the underlying logic.

The definitive proof: when science confirmed her intuition

Marilyn vos Savant was right, but academic validation came only later. MIT conducted computer simulations that mathematically confirmed her answer. The TV show MythBusters performed physical experiments to demonstrate it practically. Some academics who had publicly criticized her acknowledged their mistakes and apologized.

What fascinated observers was not only the result but the deeper meaning: a woman with the highest IQ in history saw beyond appearances, beyond what superficial numbers suggested. What was dismissed as a glaring mistake turned out to be a brilliant intuition supported by mathematics.

The story of Marilyn vos Savant and the Monty Hall problem remains a fascinating lesson on how pure intelligence does not always coincide with instant recognition, and how science ultimately has the task of validating what a brilliant mind perceives.
