In psychology, Stockholm syndrome is a term used to describe a paradoxical psychological phenomenon wherein hostages express adulation and have positive feelings towards their captors that appear irrational in light of the danger or risk endured by the victims, essentially mistaking a lack of abuse from their captors as an act of kindness.  The FBI’s Hostage Barricade Database System shows that roughly 27% of victims show evidence of Stockholm syndrome. The syndrome is named after the Norrmalmstorg robbery of Kreditbanken at Norrmalmstorg in Stockholm, in which the bank robbers held bank employees hostage from August 23 to August 28, 1973. In this case, the victims became emotionally attached to their captors, and even defended them after they were freed from their six-day ordeal. The term "Stockholm Syndrome" was coined by the criminologist and psychiatrist Nils Bejerot, who assisted the police during the robbery, and referred to the syndrome in a news broadcast. It was originally defined by psychiatrist Frank Ochberg to aid the management of hostage situations.
- ... disagreement as to what factors characterize incidents that contribute to the development of Stockholm syndrome. Research has suggested that hostages may exhibit the condition in situations that feature captors who do not abuse the victim, a long duration before resolution, continued contact between the perpetrator and hostage, and a high level of emotion. In fact, experts have concluded that the intensity, not the length of the incident, combined with a lack of physical abuse more likely will create favorable conditions for the development of Stockholm syndrome.
- The following are viewed as the conditions necessary for Stockholm syndrome to occur.
- Hostages who develop Stockholm syndrome often view the perpetrator as giving life by simply not taking it. In this sense, the captor becomes the person in control of the captive’s basic needs for survival and the victim’s life itself.
- The hostage endures isolation from other people and has only the captor’s perspective available. Perpetrators routinely keep information about the outside world’s response to their actions from captives to keep them totally dependent.
- The hostage taker threatens to kill the victim and gives the perception of having the capability to do so. The captive judges it safer to align with the perpetrator, endure the hardship of captivity, and comply with the captor than to resist and face murder.
- The captive sees the perpetrator as showing some degree of kindness. Kindness serves as the cornerstone of Stockholm syndrome; the condition will not develop unless the captor exhibits it in some form toward the hostage. However, captives often misinterpret a lack of abuse as kindness and may develop feelings of appreciation for this perceived benevolence. If the captor is purely evil and abusive, the hostage will respond with hatred. But, if perpetrators show some kindness, victims will submerge the anger they feel in response to the terror and concentrate on the captors’ “good side” to protect themselves.
- In cases where Stockholm syndrome has occurred, the captive is in a situation where the captor has stripped nearly all forms of independence and gained control of the victim’s life, as well as basic needs for survival. Some experts say that the hostage regresses to, perhaps, a state of infancy; the captive must cry for food, remain silent, and exist in an extreme state of dependence. In contrast, the perpetrator serves as a 'mother' ﬁgure protecting the 'child' from a threatening outside world, including law enforcement’s deadly weapons. The victim then begins a struggle for survival, both relying on and identifying with the captor. Possibly, hostages’ motivation to live outweighs their impulse to hate the person who created their dilemma.
The FBI's theories about Stockholm Syndrome development are not, however, perfectly representative of the opinions of other psychologists who have studied the subject.
Stockholm syndrome is a psychological shift that occurs in captives when they are threatened gravely but are shown acts of kindness by their captors. Captives who exhibit the syndrome tend to sympathize with and think highly of their captors. When subjected to prolonged captivity, these captives can develop a strong bond with their captors, in some cases including a sexual interest.
According to the psychoanalytic view of the syndrome, this tendency might be the result of employing the strategy evolved by newborn babies to form an emotional attachment to the nearest powerful adult in order to maximize the probability that this adult will enable—at the very least—the survival of the child, if not also prove to be a good parental figure. This syndrome is considered a prime example for the defense mechanism of identification.
- Mary McElroy was kidnapped and held for ransom in 1934 and released by her captors unharmed. She described the incident as a positive one and, when her captors were apprehended and given harsh sentences (including one death sentence), McElroy defended them. According to reports, she suffered from feelings of guilt concerning the case which compromised her mental and physical health. She took her own life in 1940.
- Patty Hearst was kidnapped by the Symbionese Liberation Army in 1974. After two months in captivity, she actively took part in a robbery they were orchestrating. Her unsuccessful legal defense claimed that she suffered from Stockholm syndrome and was coerced into aiding the SLA. She was convicted and imprisoned for her actions in the robbery, though her sentence was commuted in February 1979 by President Jimmy Carter, and she received a Presidential pardon from President Bill Clinton on January 20, 2001 (among his last official acts before leaving office).
- Jaycee Lee Dugard was abducted at age 11 by Phillip & Nancy Garrido at a school bus stop in 1991 and was imprisoned at their residence for 18 years. In August 2009, Phillip brought Nancy & Jaycee (who was living under the alias "Alyssa") along with two girls that Garrido fathered with Jaycee during her captivity, to be questioned by Garrido's parole officer after he noticed some suspicious behavior. She did not reveal her identity when she was questioned alone. Instead, she told investigators she was a battered wife from Minnesota who was hiding from her abusive husband, and described Garrido as a "great person" who was "good with her kids". Dugard has since admitted to forming an emotional bond with Garrido with great guilt and regret.
An inverse of Stockholm syndrome called "Lima syndrome" has been proposed, in which abductors develop sympathy for their hostages. It was named after an abduction at the Japanese Embassy in Lima, Peru in 1996, when members of a militant movement took hostage hundreds of people attending a party in the official residence of Japan's ambassador. Within a few hours, the abductors had set free most of the hostages, including the most valuable ones, due to sympathy.
