How did it get its name?
The term can be traced back to Swedish criminologist and psychiatrist Nils Bejerot, who advised police in a standoff during a bank robbery in the Swedish capital in August 1973. During the standoff, some of the hostages appeared to side with the hostage-takers and against the police, a phenomenon Bejerot called “Norrmalmstorg syndrome”. Internationally, it became known as Stockholm syndrome.
Bejerot’s daughter, Susanne says her father - who died in 1988 - never thought the term would gain such traction worldwide. “He didn’t understand that it would become such a big thing,” she said.
What happened during that bank robbery?
On August 23, 1973, convicted thief Jan-Erik Olsson, 32, tried to rob a bank in downtown Stockholm while on furlough from prison. Police responded quickly, and a standoff ensued.
Olsson, armed with a submachine gun, took four bank employees hostage and demanded 3 million kronor, a bulletproof vest and a getaway car. He also demanded that his former jail mate, Clark Olofsson, be released from prison and brought to the bank. Authorities agreed.
The drama played out on live television in Sweden as police tried to persuade Olsson and Olofsson to surrender. Even Prime Minister Olof Palme got involved in the negotiations.
At one point, a hostage, Kristin Enmark, told Palme over the telephone that she was afraid of the police, not of the two criminals. She appealed to authorities to meet their demands. Enmark later said she had developed a bond with Olofsson, whom she saw as the guarantor of her safety.
Two police officers were injured with gunshot wounds during the standoff, which ended on August 28 when police, using tear gas, stormed the bank, arrested Olsson and Olofsson and freed the hostages.
What are other examples of Stockholm Syndrome?
One of the most well-known cases happened the following year, 1974, when Patty Hearst, the 19-year-old granddaughter of a wealthy newspaper magnate was kidnapped in the United States by the Symbionese Liberation Army, an unknown armed revolutionary group.
Two months later, questions concerning Hearst’s ties to her captors — and the notion of Stockholm syndrome — arose after Hearst declared her allegiance to the SLA, denounced her family and posed for a photograph carrying a weapon in front of the SLA flag. She was arrested in 1975 and was sentenced to seven years in prison. US President Jimmy Carter commuted her sentence in 1979. She was later pardoned by President Bill Clinton.
Stockholm syndrome has also been applied in the context of victims of domestic violence or childhood sexual abuse who develop connections with their abusers.
Real or myth?
Stockholm syndrome isn’t listed as a diagnosis by the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders or the International Statistical Classification of Diseases and Related Health Problems. Some experts question whether it’s a psychological condition at all or just a survival strategy — rational choices made by some people as they face extreme danger.
In the US some law enforcement experts have said the phenomenon is rare and overpublicised by the media. But it still features frequently in popular culture, including books, films and music, and has entered the English lexicon as an informal term for people who forge unexpected bonds with others who treat them badly.
Stockholm syndrome inspired movies like the 2013 thriller Labor Day with Kate Winslet, Josh Brolin and Gattlin Griffith, and the 2018 film Stockholm with Ethan Hawke and Noomi Rapace. The latter recounted the failed 1973 bank heist. It’s also the title of songs by bands including One Direction, Muse and Blink-182.
