Mass formation psychosis, also known as mass formation hysteria, is a controversial phenomenon that has gained widespread attention in recent times. It refers to a state in which a large number of individuals in a group become affected by a shared delusion or mental illness, leading to symptoms such as anxiety, paranoia, and even hallucinations. While the concept of mass formation psychosis has been recognized for many years, its validity as a distinct clinical entity is still a subject of debate among mental health professionals.
The term “mass formation psychosis” was first introduced in 2014 by Dutch psychologist and former professor of medical psychology at the University of Amsterdam, Dr. Jan van der Linden. According to van der Linden, mass formation psychosis occurs when a large group of people becomes intensely focused on a shared belief or idea, leading to a collective state of hypnosis and delusion. The concept was later popularized in a book titled “Virus Mania” by Dr. Claus Köhnlein and Dr. Karsten Münstedt, which claimed that mass hysteria can lead to the creation of false epidemics and public health scares.
There have been several high-profile examples of mass formation psychosis throughout history. One of the most well-known cases occurred in Salem, Massachusetts, in the late 17th century, when a group of young girls claimed to be possessed by witches, leading to a mass hysteria that resulted in the execution of 20 people. Another example is the so-called “Dancing Plague” that occurred in Strasbourg, France, in 1518, in which hundreds of people danced uncontrollably for days, possibly due to a combination of social and psychological factors.
While these historical cases are certainly intriguing, the validity of mass formation psychosis as a distinct clinical entity remains a subject of debate. Some experts argue that the phenomenon is simply a form of mass hysteria or groupthink, in which individuals become caught up in a shared belief or idea, leading to a temporary state of irrationality. Others suggest that mass formation psychosis may be a manifestation of underlying psychological or social factors, such as anxiety, stress, or trauma.
One of the key challenges in studying mass formation psychosis is the difficulty in defining and measuring the phenomenon. Unlike traditional psychiatric disorders, mass formation psychosis is not listed in the Diagnostic and Statistical Manual of Mental Disorders (DSM), the standard reference manual used by mental health professionals. This has led some experts to question whether mass formation psychosis is a distinct clinical entity, or simply a label for a complex set of psychological and social phenomena.
Despite these challenges, there is some evidence to suggest that mass formation psychosis may be a real and distinct phenomenon. In a recent study published in the Journal of Medical Internet Research, researchers analyzed the online behavior of individuals who believed in COVID-19 conspiracy theories and found that they were more likely to be susceptible to mass formation psychosis. Other studies have also suggested that certain social and psychological factors, such as group cohesion and social isolation, may contribute to the development of mass formation psychosis.
There have been several case studies of mass formation psychosis throughout history, some of which have become well-known examples of this phenomenon. These cases often involve groups of individuals becoming intensely focused on a shared belief or idea, leading to a collective state of hypnosis and delusion. Here are some examples of famous cases of mass formation psychosis:
Salem Witch Trials – In the late 17th century, a group of young girls in Salem, Massachusetts claimed to be possessed by witches, leading to a mass hysteria that resulted in the execution of 20 people. The girls exhibited symptoms such as convulsions, fits, and hallucinations, and accused several people in the community of witchcraft. The hysteria spread quickly, with many others in the community also claiming to have been bewitched. It is now believed that the hysteria was fueled by a combination of social and psychological factors, including religious fervor, group dynamics, and mass suggestion.
Dancing Plague of 1518 – In the summer of 1518, a strange phenomenon occurred in the town of Strasbourg, France. A woman named Frau Troffea began dancing in the streets, and soon others joined her. Within a week, hundreds of people were dancing uncontrollably in the streets, often until they collapsed from exhaustion or died. The phenomenon lasted for several months and is now believed to have been a form of mass hysteria, fueled by social and psychological factors such as stress, anxiety, and religious fervor.
The Mad Gasser of Mattoon – In 1944, the town of Mattoon, Illinois was gripped by a wave of hysteria after several people reported being attacked by a mysterious gas-wielding assailant. The reports led to a mass panic, with many people claiming to have seen or been attacked by the “Mad Gasser”. The hysteria was eventually traced to a combination of mass suggestion and a string of unrelated crimes, but the legend of the Mad Gasser lives on as an example of mass formation psychosis.
UFO Sightings – Throughout the 20th century, there have been several instances of mass hysteria related to sightings of unidentified flying objects (UFOs). In many cases, large groups of people reported seeing strange objects in the sky, and some even claimed to have been abducted by aliens. The phenomenon has been attributed to a combination of social and psychological factors, including a desire for attention and a fascination with science fiction.
COVID-19 Conspiracy Theories – In recent years, the COVID-19 pandemic has led to a surge in conspiracy theories and false information. Some individuals have become intensely focused on these beliefs, leading to a state of mass formation psychosis. For example, there have been cases of groups of people gathering in public spaces to protest against COVID-19 restrictions, often without masks or social distancing. These events have been fueled by a shared belief in COVID-19 conspiracy theories, and can be seen as a form of mass formation psychosis.
In conclusion, mass formation psychosis remains a controversial and poorly understood phenomenon. While there is some evidence to suggest that it may be a real and distinct clinical entity, more research is needed to understand the underlying psychological and social factors that contribute to its development. As with any psychiatric disorder, it is important for mental health professionals to remain open-minded and cautious when considering the diagnosis of mass formation psychosis, and to use a comprehensive and evidence-based approach when treating affected individuals.
