For starters, QAnon, like the painkiller abuse epidemic driven by the drug oxycodone, engulfs people who are most vulnerable to its content. An overwhelming proportion of QAnon followers arrested in connection with the Jan. 6 insurrection, for instance, have mental health problems, including bipolar disorder, schizophrenia and post-traumatic stress disorder, according to a University of Maryland analysis. If you believe the world is out to get you, you are probably more likely to embrace QAnon narratives that explain exactly how the world is out to get you.

Their psychological pain may make these people especially vulnerable to QAnon’s content, which often speaks to fears, anxieties and anger. People who worry about contamination, for example, are probably more susceptible to lies about the Covid-19 vaccine carrying a contaminating agent that makes their children gay or transgender.

It is also likely that prolonged exposure to QAnon content exacerbates or even triggers mental illness, as watching video after video about horrific devastation can have a detrimental effect on anyone’s mental health. This then increases the appeal of the remedies QAnon prescribes, such as refusing Covid vaccines, protesting mask mandates or even storming the Capitol in Washington. Though to be sure, most people with mental health problems do not believe in QAnon conspiracy theories, just as a sizable proportion of QAnon followers are not mentally ill.
