For six days in August 1973, four bank employees were held at gunpoint in a vault beneath Norrmalmstorg square in Stockholm. When it was finally over, they wouldn’t testify against the men who’d held them. One of them, a 23-year-old named Kristin Enmark, said she’d been more frightened of the police.
A psychiatrist advising that police operation had a tidy explanation ready. He decided the hostages had caught something, and the name he gave it — Stockholm syndrome — outlived everyone in the vault. It’s now the standard shorthand for any victim who seems loyal to the person hurting them. There’s just one problem with it. As a medical diagnosis, it has never existed.
The short version
- The term comes from a six-day siege at Kreditbanken on Norrmalmstorg, Stockholm, in August 1973.
- Psychiatrist Nils Bejerot coined it from outside the vault, to explain why the hostages sided with the robber over the police.
- A 2008 review of the actual evidence found 12 mostly-anecdotal papers, no agreed definition, and no entry in any diagnostic manual.
- Hostage Kristin Enmark has spent fifty years saying the obvious: she feared a reckless police assault and acted to survive.
Six Days in the Vault
On 23 August 1973, an escaped convict named Jan-Erik Olsson walked into Kreditbanken, pulled a gun, and took four employees hostage. His first demand was oddly specific: bring me Clark Olofsson, a well-known criminal he’d met in prison. The police obliged. For six days the two men and their captives lived in the bank’s vault while negotiators stalled and the country watched it on television. It ended when police drilled through the ceiling and dropped tear gas in. Everyone came out alive. What stuck in the public memory afterwards wasn’t the robbery. It was that the hostages had seemed to be on the wrong side — wary of the police, protective of the men with the gun.
Where the Diagnosis Came From
The explanation came from Nils Bejerot, a psychiatrist and criminologist advising the police from the command post outside. Watching the hostages defend their captors, he cast the loyalty as a pathology, a bond that had hijacked their judgement. It was a neat story, and neat stories travel. Within a few years “Stockholm syndrome” had jumped from one Swedish bank to films, headlines, and eventually the whole true-crime industry. The one thing it never picked up along the way was evidence.
What the Evidence Actually Says
In 2008 a team led by Namnyak went looking for that evidence and published the result in Acta Psychiatrica Scandinavica, under a title that gives away the ending: “Stockholm syndrome: psychiatric diagnosis or urban myth?” They searched the major databases and came back with twelve papers, “mostly case reports,” thick with “ambiguity in the use of the term” and, the line that matters most, “no validated diagnostic criteria.” The condition, they wrote, “is not described in any international classification system.” No DSM. No ICD. Their read was that the resemblance between famous cases probably owes more to how the press writes them up than to any shared disorder in the victims.
The Woman the Label Was Built On
The sharpest problem with the diagnosis is the case that named it. Kristin Enmark hasn’t gone quiet in the fifty years since; she has said, again and again, that her behaviour in the vault was rational. She thought the police were gambling with four lives. She trusted the men who could actually see her over the marksmen who couldn’t. “I wasn’t in love,” she has said. “I was a 23-year-old woman who survived six terrifying days in a bank vault.” The political scientist Cecilia Åse, who went back over the episode in 2015, puts it harder still: the syndrome, she argues, was “created from scratch to make allowances for the fact that these women acted rationally in this situation” — a way of turning the state’s failure to protect them into a disorder of the women it failed.
So What’s Real?
None of this means captives never bond with the people controlling them. They can, and that bond has been studied seriously. Trauma bonding was actually measured, and it rests on identifiable conditions; the reasons people stay with someone who harms them have decades of research behind them. The trouble isn’t the phenomenon. It’s the packaging: a messy, one-off human reaction stamped with a clinical-sounding name no manual ever accepted. What the evidence supports looks less like a switch that flips in every hostage and more like the slow, deliberate loyalty built inside a group organised around one charismatic leader.
Frequently Asked Questions
Is Stockholm syndrome a real medical diagnosis?
No. It doesn’t appear in the DSM or the ICD, and a 2008 systematic review found no validated diagnostic criteria for it. Researchers treat it as poorly defined and propped up by a handful of anecdotal cases rather than real study.
Where does the term “Stockholm syndrome” come from?
From a six-day bank siege at Kreditbanken in Stockholm in August 1973. Nils Bejerot, a psychiatrist advising the police, used it to explain why the four hostages seemed loyal to the robber holding them instead of to the authorities.
Did the hostages actually bond with their captor?
Kristin Enmark, one of the four, has always said her behaviour was rational — she feared the police assault more than the robbers and did what kept her alive. The scholar Cecilia Åse argues the “syndrome” was invented to explain away that reasonable fear as a psychological disorder.
