Conspiracy theory belief, COVID-19, and medical intervention
As for medical conspiracy theories, none have flourished recently more so than those involving the COVID-19 pandemic. As a recent editorial by Stein and colleagues noted, “Some conspiratorial claims include assertions that COVID‐19 is a hoax; arguments that the virus was created artificially and spread on purpose as a bioweapon; or allegations that governments are using the emergency situation to pursue their antidemocratic goals. … Other conspiracies argued that people in power are taking advantage of the pandemic as a plan to inject microchip quantum-dot spy software and monitor people.”
Stein and colleagues make the important point that a “key difference between COVID‐19 and the 1918 flu pandemic ... is that [now] a highly interconnected world, to a great extent on social media, is setting the stage for distributing information and misinformation about COVID‐19.”
Consider the following composite vignette: Mr. A is a 70-year-old retiree with a history of COPD who has been advised by his PCP to get vaccinated against COVID-19. He is extremely reluctant to do so, fearing that “the vaccine is going to change my DNA” and “might even give me COVID.” He has heard from friends on social media that vaccine developers “faked the results” and are “in cahoots with the federal government.” Mr. A has heard “experts” declare the vaccines safe, but does not trust them. Mr. A has no psychiatric or substance abuse history, and there are no cognitive, perceptual, or other abnormalities in Mr. A’s mental status exam.
Mr. A’s beliefs qualify as a “conspiracy theory,” but probably represent widely held misconceptions about COVID-19 vaccines, as well as widespread mistrust of pharmaceutical companies and the federal government. Based on the information provided, there is no basis for concluding that Mr. A is psychotic or delusional. His beliefs appear to be the result of “epistemic mistrust” of authoritative informational accounts, biased information processing, and exposure to misinformation.
How should the physician manage and care for patients like Mr. A? Absent frank delusions, there is no role for antipsychotic medication, though . In addition to providing accurate medical information to the patient, the physician should avoid arguing, or trying to “talk the patient out of” his or her belief. Instead, the focus should be on sustaining and strengthening the physician-patient alliance, establishing an atmosphere of respect and safety, clarifying differences in trusted sources of medical information, and allowing the patient time to process the physician’s recommendations.
One-to-one engagement with health care providers has proved effective in reducing vaccine hesitancy and correcting misinformation. For patients with less fixed conspiracy theory beliefs, it may sometimes be helpful to gently offer alternative hypotheses to the patient’s conspiracy theory, using elements of cognitive-behavioral therapy (CBT). For example, a physician might ask, “Is it possible that the online source you read was mistaken about the vaccine changing your DNA?” while reminding patients that – contrary to popular belief – mRNA vaccines have been in development against cancer for several decades.
Challenging beliefs collaboratively and acknowledging areas of uncertainty, rather than confronting or arguing about false beliefs, can foster trust between physician and patient and, at the very least, open a dialogue regarding potential exposure to medical misinformation. “Inoculation” strategies that present and then dispel misinformation before patients become aware of it are among the best supported strategies for mitigating conspiracy theory belief. Ideally, physicians and health care systems should maintain an ongoing “inventory” of medical misinformation circulating online and “beat it to the punch” with reliable information.
Finally, because believing in conspiracy theories is often associated with a sense of uncertainty, and feeling that one’s life is “out of control,” medical interventions can be framed as ways of regaining control and appealing to patients’ values; for example, saying, “By getting the vaccine, you’ll be more likely to stay in good health, protect your family, and do all the things you want to do.”
