Psychogenic Index
This is a working collection of my observations on mass psychogenic illness and similar, related phenomena.
The focus of this blog is not to study certain cases, but instead the underlying patterns that allow such events to emerge: interpretation, attention, expectation, and their interaction within groups, specifically:
— the conditions under which symptoms become “contagious”
— the role of social and environmental context in symptom formation
— distinctions and overlaps between collective and individual psychogenic presentations
— the evolution of these phenomena in digital environments.
This is not a comprehensive account, but a working index. Updates are not regular.
