Why trolls, extremists, and others spread conspiracy theories they don’t believe

There has been a lot of research on the types of people who believe conspiracy theories, and their reasons for doing so. But there’s a wrinkle: My colleagues and I have found that there are a number of people sharing conspiracies online who don’t believe their own content.

They are opportunists. These people share conspiracy theories to promote conflict, cause chaos, recruit and radicalize potential followers, make money, harass, or even just to get attention.

There are several types of this sort of conspiracy-spreader trying to influence you.

Coaxing conspiracists—the extremists

In our chapter of a new book on extremism and conspiracies, my colleagues and I discuss evidence that certain extremist groups intentionally use conspiracy theories to entice adherents. They are looking for a so-called “gateway conspiracy” that will lure someone into talking to them, and then be vulnerable to radicalization. They try out multiple conspiracies to see what sticks.

Research shows that people with positive feelings for extremist groups are significantly more likely to knowingly share false content online. For instance, the disinformation-monitoring company Blackbird.AI tracked over 119 million COVID-19 conspiracy posts from May 2020, when activists were protesting pandemic restrictions and lockdowns in the United States. Of these, over 32 million tweets were identified as high on their manipulation index. Those posted by various extremist groups were particularly likely to carry markers of insincerity. For instance, one group, the Boogaloo Bois, generated over 610,000 tweets, of which 58 percent were intent on incitement and radicalization.

You can also just take the word of the extremists themselves. When the Boogaloo Bois militia group showed up at the Jan. 6, 2021, insurrection, for example, members stated they didn’t actually endorse the stolen election conspiracy, but were there to “mess with the federal government.” Aron McKillips, a Boogaloo member arrested in 2022 as part of an FBI sting, is another example of an opportunistic conspiracist. In his own words: “I don’t believe in anything. I’m only here for the violence.”
