Writers rule on The Simpsons, not the actors, he says. The result is a show packed with references to art, literature, pop culture, politics and science.

“When that many smart people produce a television show, it’s bound to make some startling ‘predictions’,” he says.

Another possible factor at play: “The law of truly large numbers,” a concept presented by Harvard mathematicians Frederick Mosteller and Persi Diaconis in their 1989 paper Methods for Studying Coincidences.

“With a large enough sample, any outrageous thing is apt to happen,” the law states. The Simpsons is the longest-running scripted TV series in history.

For fans looking for answers outside conventional logic, Dr Bernard Beitman, author of Connecting With Coincidence, offers the existence of the “psychosphere,” our mental atmosphere that is essentially “group mind in action.”

“Under the right conditions, we can know things that we don’t know we know, and we can sometimes predict events,” says Beitman, a former chairman of the psychiatry department at the University of Missouri.

Below are some coincidences from The Simpsons, and how they can (or can’t) be explained.

September 11th, 2001

Predicted: 1997
Happened: 2001

In The City of New York vs Homer Simpson, a moment alludes to the 9/11 attacks on the World Trade Centre in New York City, and not even Jean could explain it.

“There is a frame where there’s a brochure that says New York at $9 a day, and behind the nine are the twin towers … it looks like ‘9/11’. That one is a completely bizarre, strange thing,” he says.

In 2010, Bill Oakley, an executive producer on the show at the time, told The New York Observer: “$9 was picked as a comically cheap fare,” he says. “And I will grant that it’s eerie, given that it’s on the only episode of any series ever that had an entire act of World Trade Centre jokes.”

Disney acquires 21st Century Fox

Predicted: 1998
Happened: 2017

The most recent prediction to come true was Disney’s $52 billion deal for 21st Century Fox, announced in December. In When You Dish Upon a Star, there’s a sign that reads “20th Century Fox, a division of Walt Disney Co”.

Jean says this was in line with the writers’ forward-thinking process. The deal “was just another one,” he says. “It happens. There’s always mergers. It seemed logical, you know?”

The Higgs boson particle

Predicted: 1998
Happened: 2012

At first glance, this might seem like the freakiest Simpsons prophecy: Homer, striving to be the next great inventor, standing at a chalkboard on which a complex equation is scrawled.

The equation is a just a hair off what would become the Higgs boson particle, or “God particle,” which was discovered in 2012, decades after it was first presumed to exist.

“That equation predicts the mass of the Higgs boson,” Simon Singh, author of The Simpsons and Their Mathematical Secrets, told the Independent in 2015. “If you work it out, you get the mass of a Higgs boson that’s only a bit larger than the nano-mass of a Higgs boson actually is.”

But it can be explained to some degree: “The Higgs boson was written into the script by David Cohen, who’s one of the people with a math background on this show,” Jean says. “What he put in was a plausible guess at that time. So it wasn’t like totally out of left field.”

The Trump presidency

Predicted: 2000
Happened: 2016

While this prediction might seem amazing, it’s actually one of the show’s most logical prognoses, Jean says: “There’s a category I would call ‘plausible predictions’, which Trump would fall under.

“People have somewhat forgotten, but he was talking about running for president then,” he says.

In a 2016 interview with The Hollywood Reporter, writer Dan Greaney says the joke was intended as a warning: “That just seemed like the logical last stop before hitting bottom. It was pitched because it was consistent with the vision of America going insane.”

Super Bowl XXVI, XXVII and XXVIII

Predicted: 1992, 1993, 1994
Happened: 1992, 1993, 1994

The show predicted the NFL champions three years in a row (in an episode that was all about predictions). And yes, all three were just lucky guesses, Jean says.

In Lisa the Greek (1992) Homer and Lisa bond over sports gambling. Lisa has discovered a knack for predicting football winners, which Homer happily cashes in on. Lisa tells Homer that if the Washington Redskins defeat the Buffalo Bills in the Super Bowl, she would still love him. If they don’t, she won’t.

Washington wins, and all is well between them. Three days after the episode aired, Washington beat Buffalo 37-24.

The episode was reworked in 1993 and 1994 with the new Super Bowl-bound teams, the Dallas Cowboys and the Buffalo Bills both years. Lisa went with Dallas. In 1993, Dallas won 52-17. In 1994, Dallas won 30-13.

1994 was the last time The Simpsons altered the episode, and the last time Buffalo made a Super Bowl appearance. – New York Times
