Media Skepticism, Not Just COVID News, Predicted Vaccine Conspiracy Beliefs
One popular explanation for vaccine conspiracy theories is that the pandemic created them; that a flood of confusing headlines and social media posts pushed people toward believing governments and drug companies were hiding the truth. However, distrust in mainstream media was already there when researchers started watching in 2020, and it only grew stronger from there.
A five-wave study published in Scientific Reports suggests the COVID-19 explanation misses something important. Researchers followed the same 2,000 people in Japan for five years, starting in April 2020, and found that people who already distrusted mainstream news early on, and grew even more distrustful as time went on, were the ones most likely to believe vaccines were part of a cover-up by 2024.
This finding carries extra weight because of where it came from. Japan’s major news outlets have traditionally emphasized political neutrality, and the country’s media landscape has been less fragmented along partisan lines than in the United States. That makes it a useful place to study media distrust without the usual noise of partisan echo chambers clouding the picture.
Institutional Distrust and Microchip Myths Are Not the Same Belief
Using an eight-item survey given in the study’s final year, researchers found two separate kinds of vaccine conspiracy belief, not one big blob of “distrust.” The first, which researchers call institutional conspiracy belief, is the idea that governments and drug companies are hiding vaccine dangers or covering up links between vaccines and health problems, like claiming officials are burying evidence that a vaccine causes harm. This one was common and varied a lot from person to person.
A second, rarer category involves far more extreme claims, such as vaccines containing tracking microchips or enabling mind control. Only a small minority endorsed these ideas. Most people, even those skeptical of institutions, rejected the microchip-style narratives outright.
Someone who suspects pharmaceutical companies of hiding side effects is working from a different psychological place than someone convinced vaccines contain tracking devices. Treating both as the same problem risks building public health messages that miss their target.
Media Skepticism Outweighed Media Use as a Predictor
Starting in April 2020, researchers recruited 2,000 participants through an online platform in Japan. Each year through April 2024, they re-surveyed as many original participants as were willing to continue, ending with 600 by the final wave. Participants reported how often they used television, newspapers and social media, how skeptical they felt toward mainstream news, and how confident they were in judging accurate information themselves. The conspiracy belief questions were asked only once, at the end, in 2024.
Age mattered too: younger participants scored higher on both types of belief. But the single strongest factor behind the common, cover-up-style belief was media skepticism, both how distrustful people were at the start and how much more distrustful they became.
Watching less traditional TV and print news was also linked to higher conspiracy beliefs, but that link disappeared once researchers factored in skepticism itself. In other words, it wasn’t really about how much news people consumed. It was about how much they trusted the source in the first place.
Social media use alone did not clearly predict institutional conspiracy beliefs. Some patterns hinted at a possible link to the rarer, extreme beliefs, but researchers described those results as speculative given how few participants held such views.
