Mass psychogenic illness
From The Art and Popular Culture Encyclopedia
"Society appears to be subject, every now and then, to periods of moral panic. A condition, episode, person or group emerges to become defined as a threat to societal values and interests."--Folk Devils and Moral Panics (1972) by Stanley Cohen
"Contagion is so powerful that it forces upon individuals not only certain opinions, but certain modes of feeling as well. Contagion is the cause of the contempt in which, at a given period, certain works are held--the example of "Tannhauser" may be cited--which, a few years later, for the same reason are admired by those who were foremost in criticising them."--The Crowd: A Study of the Popular Mind (1895) by Gustave Le Bon
"Hitler understands how to raise this instinct to the power of a collective psychosis. He knows that the hate-lust is more easily inflamed in the presence of a visible and tangible enemy. That is why he has incited the Nazi fury against the Jews."--Mark My Words ! (1978) by Mark Goulden
"Orson Welles first gained wide American notoriety on the 1938 War of the Worlds radio broadcast of H. G. Wells's novel of the same name. Adapted to sound like an actual news broadcast, it caused panic and even mass hysteria. Welles and his biographers subsequently claimed he was exposing the gullibility of American audiences in the tense preamble to the Second World War."--Sholem Stein
Mass hysteria, also called collective hysteria, mass psychogenic illness, or collective obsessional behavior, is the sociopsychological phenomenon of the manifestation of the same or similar hysterical symptoms by more than one person. A common manifestation of mass hysteria occurs when a group of people believe they are suffering from a similar disease or ailment.
Mass hysteria typically begins when an individual becomes ill or hysterical during a period of stress. After this initial individual shows symptoms, others begin to manifest similar symptoms, typically nausea, muscle weakness, fits or headache.
The features of mass hysteria include no plausible cause found, ambiguous symptoms, rapid escalation of cases - often spread by line of sight - and rapid remission of symptoms. Demographically, cases are higher in females and those with greater use of medical services. Other factors that contribute to the severity of the symptoms and spread are protective clothing worn by emergency services and mistaken or misleading investigations.
Sightings of religious miracles are often attributed to mass hysteria.
The earliest studied cases linked with epidemic hysteria are the dancing manias of the Middle Ages, including St. John's dance and tarantism. These were supposed to be associated with spirit possession or the bite of the tarantula. Those with dancing mania would dance in large groups, sometimes for weeks at a time. The dancing was sometimes accompanied by stripping, howling, the making of obscene gestures, or even (reportedly) laughing or crying to the point of death. Dancing mania was widespread over Europe.
Between the 15th and 19th centuries, instances of motor hysteria were common in nunneries. The young ladies that made up these convents were sometimes forced there by family. Once accepted, they took vows of chastity and poverty. Their lives were highly regimented and often marked by strict disciplinary action. The nuns would exhibit a variety of behaviors, usually attributed to demonic possession. They would often use crude language and exhibit suggestive behaviors. One convent's nuns would regularly meow like cats. Priests were often called in to exorcise demons.
18th to 21st centuries
W. H. Phoon, Ministry of Labour in Singapore, gives a case study of six outbreaks of MPI in Singapore factories between 1973 and 1978. They were characterized by (1) hysterical seizures of screaming and general violence, wherein tranquilizers were ineffective (2) trance states, where a worker would claim to be speaking under the influence of a spirit or jinn and (3) frightened spells: some workers complained of unprecedented fear, or of being cold, numb, or dizzy. Outbreaks would subside in about a week. Often a bomoh (medicine man) would be called in to do a ritual exorcism. This technique was not effective and sometimes seemed to exacerbate the MPI outbreak. Females and Malay people were affected disproportionately.
Especially notable is the "June Bug" outbreak: In June 1962, a peak month in factory production, 62 workers at a dressmaking factory in a textile town in the Southern United StatesTemplate:Efn experienced symptoms including severe nausea and breaking out on the skin. Most outbreaks occurred during the first shift, where four fifths of the workers were female. Of 62 total outbreaks, 59 were women, some of whom believed they were bitten by bugs from a fabric shipment, so entomologists and others were called in to discover the pathogen, but none was found. Kerchoff coordinated the interview of affected and unaffected workers at the factory and summarizes his findings:
- Strain – those affected were more likely to work overtime frequently and provide the majority of the family income. Many were married with children.
- Affected persons tended to deny their difficulties. Kerchoff postulates that such were "less likely to cope successfully under conditions of strain."
- Results seemed consistent with a model of social contagion. Groups of affected persons tended to have strong social ties.
Kerchoff also links the rapid rate of contagion with the apparent reasonableness of the bug infestation theory and the credence given to it in accompanying news stories.
Stahl and Lebedun describe an outbreak of mass sociogenic illness in the data center of a university town in the United States Midwest in 1974. Ten of 39 workers smelling an unconfirmed "mystery gas" were rushed to a hospital with symptoms of dizziness, fainting, nausea and vomiting. They report that most workers were young women either putting their husbands through school or supplementing the family income. Those affected were found to have high levels of job dissatisfaction. Those with strong social ties tended to have similar reactions to the supposed gas, which only one unaffected woman reported smelling. No gas was detected in subsequent tests of the data center.
Mass hysteria affected schools in Berry, Alabama, and Miami Beach in 1974, with the former episode taking the form of recurring itches, and the latter initially triggering fears of poison gas (it was traced back to a popular student who happened to be sick with a virus).
A wide variety of symptoms were manifested, including headache, dizziness, impeded respiration, weakness/adynamia, burning sensations, cramps, retrosternal/chest pain, dry mouth and nausea. After the illness had subsided, a bipartisan Federal Commission released a document, offering the explanation of psychogenic illness. Radovanovic of the Department of Community Medicine and Behavioural Sciences Faculty of Medicine in Safat, Kuwait, reports:
This document did not satisfy either of the two ethnic groups. Many Albanian doctors believed that what they had witnessed was an unusual epidemic of poisoning. The majority of their Serbian colleagues also ignored any explanation in terms of psychopathology. They suggested that the incident was faked with the intention of showing Serbs in a bad light but that it failed due to poor organization.
Rodovanovic expects that this reported instance of mass sociogenic illness was precipitated by the demonstrated volatile and culturally tense situation in the province.
The Tanganyika laughter epidemic of 1962 was an outbreak of laughing attacks rumored to have occurred in or near the village of Kanshasa on the western coast of Lake Victoria in the modern nation of Tanzania, eventually affecting 14 different schools and over 1,000 people.
On the morning of Thursday 7 October 1965, at a girls' school in Blackburn in England, several girls complained of dizziness. Some fainted. Within a couple of hours, 85 girls from the school were rushed by ambulance to a nearby hospital after fainting. Symptoms included swooning, moaning, chattering of teeth, hyperpnea, and tetany. Moss and McEvedy published their analysis of the event about one year later. Their conclusions follow. Their conclusion about the above-average extraversion and neuroticism of those affected is not necessarily typical of MPI:
- Clinical and laboratory findings were essentially negative.
- Investigations by the public health authorities did not uncover any evidence of pollution of food or air.
- The epidemiology of the outbreak was investigated by means of questionnaires administered to the whole school population. It was established that the outbreaks began among the 14-year-olds, but that the heaviest incidence moved to the youngest age groups.
- By using the Eysenck Personality Inventory, it was established that, in all age groups, the mean E [extraversion] and N [neuroticism] scores of the affected were higher than those of the unaffected.
- The younger girls proved more susceptible, but disturbance was more severe and lasted longer in the older girls.
- It was considered that the epidemic was hysterical, that a previous polio epidemic had rendered the population emotionally vulnerable, and that a three-hour parade, producing 20 faints on the day before the first outbreak, had been the specific trigger.
- The data collected were thought to be incompatible with organic theories and with the compromise theory of an organic nucleus.
Another possible case occurred in Belgium in June 1999 when people, mainly schoolchildren, became ill after drinking Coca-Cola. In the end, scientists were divided over the scale of the outbreak, whether it fully explains the many different symptoms and the scale to which sociogenic illness affected those involved.
A possible outbreak of mass psychogenic illness occurred at Le Roy Junior-Senior High School in 2011, in upstate New York, US, in which multiple students began having symptoms similar to Tourette syndrome. Various health professionals ruled out such factors as Gardasil, drinking water contamination, illegal drugs, carbon monoxide poisoning and various other potential environmental or infectious causes, before diagnosing the students with a conversion disorder and mass psychogenic illness.
Starting around 2009, a spate of apparent poisonings at girls' schools across Afghanistan began to be reported; symptoms included dizziness, fainting and vomiting. The United Nations, World Health Organization and NATO's International Security Assistance Force carried out investigations of the incidents over multiple years, but never found any evidence of toxins or poisoning in the hundreds of blood, urine and water samples they tested. The conclusion of the investigators was that the girls were experiencing a mass psychogenic illness.
In August 2019 the BBC reported that schoolgirls at the Ketereh national secondary school (SMK Ketereh) in Kelantan, Malaysia, started screaming, with some claiming to have seen 'a face of pure evil'. Simon Wessely of King's College Hospital, London, suggested it was a form of 'collective behaviour'. Robert Bartholomew, an American medical sociologist and author, said, "It is no coincidence that Kelantan, the most religiously conservative of all Malaysian states, is also the one most prone to outbreaks." This view is supported by Afiq Noor, an academic, who argues that the stricter implementation of Islamic law in school in states such as Kelantan is linked to the outbreaks. He suggested that the screaming outbreak was caused by the constricted environment. In Malaysian culture burial sites and trees are common settings for supernatural tales about the spirits of dead infants (toyol), vampiric ghosts (pontianak) and vengeful female spirits (penanggalan). Authorities responded to the Kelantan outbreak by cutting down trees around the school.
Outbreaks of mass psychogenic illness "have been reported in Catholic convents and monasteries across Mexico, Italy and France, in schools in Kosovo and even among cheerleaders in a rural North Carolina town".
Episodes of mass hysteria have not been infrequent in Nepalese schools, at times even leading to the temporary closure of those schools involved. A unique phenomenon of "recurrent epidemic of mass hysteria" was reported from a school of Pyuthan district of western Nepal in 2018. After a 9-year-old school girl developed crying and shouting episodes, other children of the same school were seen to also become affected in rapid succession, resulting in 47 affected students (37 females, 10 males) in the same day. Since 2016, similar episodes of mass psychogenic illness have been occurring every year at the same school. This is seen as a rather atypical case of recurrent mass hysteria.
In July 2022 reports of up to 15 girls showing unusual symptoms such as screaming, trembling, and banging their heads came up from a government school in Bageshwar, Uttarakhand, India. Mass psychological illness has been suggested as a possible cause.
In late 2022 and early 2023, thousands of students, mostly girls, in numerous schools in Iran were initially believed to have been poisoned in various and undetermined manners by unidentified perpetrators and numerous arrests were made. On 29 April, 2023, the Iranian Intelligence Ministry released the findings of a comprehensive investigation which concluded that the reported illnesses were not caused by any toxic substances. Instead they were suggested to have been due to a variety of reasons including exposure to a variety of non-toxic substances, mass hysteria, and malingering.
Terrorism and biological warfare
Bartholomew and Wessely anticipate the "concern that after a chemical, biological or nuclear attack, public health facilities may be rapidly overwhelmed by the anxious and not just the medical and psychological casualties." Additionally, early symptoms of those affected by MPI are difficult to differentiate from those actually exposed to the dangerous agent.
The first Iraqi missile hitting Israel during the Persian Gulf War was believed to contain chemical or biological weapons. Though this was not the case, 40% of those in the vicinity of the blast reported breathing problems.
Right after the 2001 anthrax attacks in the first two weeks of October 2001, there were over 2300 false anthrax alarms in the United States. Some reported physical symptoms of what they believed to be anthrax.
Also in 2001, a man sprayed what was later found to be a window cleaner into a subway station in Maryland. Thirty-five people were treated for nausea, headaches and sore throats.
Beginning in 2016, some staff stationed at the US embassy in Cuba reported medical symptoms that initially were attributed to "sonic attacks", and later to other unknown weaponry. The symptoms were dubbed "Havana syndrome" by the media. The following year, some US government employees in China reported similar symptoms. Eventually, similar reports came from US government employees and their families around the globe, including in Washington DC. Due to lack of evidence of actual attack and other factors, some scientists suggested the alleged symptoms were psychogenic in nature.
Seven U.S. intelligence agencies headed by the CIA spent years reviewing thousands of possible cases of Havana syndrome and preparing a report. On March 1, 2023, the House Intelligence Committee released an unclassified version of the report, titled an "Intelligence Community Assessment". Politico summarized the results by saying, "The finding undercuts a years-long narrative, propped up by more than a thousand reports from government employees, that a foreign adversary used pulsed electro-magnetic energy waves to sicken Americans."
Children in recent refugee families
Refugee children in Sweden have been reported to fall into coma-like states on learning their families will be deported. The condition, known as resignation syndrome (Template:Lang-sv), is believed to only exist among the refugee population in the Scandinavian country, where it has been prevalent since the early part of the 21st century. Commentators state "a degree of psychological contagion" is inherent to the condition, by which young friends and relatives of the affected individual can also come to have the condition.
In a 130-page report on the condition, commissioned by the government and published in 2006, a team of psychologists, political scientists and sociologists hypothesized that it was a culture-bound syndrome, a psychological illness endemic to a specific society.
This phenomenon has later been called into question, with children witnessing that they were forced, by their parents, to act in a certain way in order to increase chances of being granted residence permits.vAs evidenced by medical records, healthcare professionals were aware of this scam, and witnessed parents who actively refused aid for their children, but remained silent. Later, Sveriges Television, Sweden's national public television broadcaster, were severely critiqued by investigative journalist Janne Josefsson for failing to uncover the truth.
After the rise of a popular breakthrough YouTube channel in 2019 where the presenter exhibits extensive Tourette's-like behavior, there was a sharp rise in young people referred to clinics specializing in tics, thought to be related to social contagion spread via the Internet, and also to stress from eco-anxiety and the COVID-19 pandemic. The authors of an August 2021 report found evidence that social media was the primary vector for transmission and that it predominantly affects adolescent girls, declaring the phenomenon the first recorded instance of "mass social media–induced illness" (MSMI).
