Commentary: Conspiratorial thinking isn't growing – Its consequences are | Op Eds

The Comet Ping Pong Pizzagate shooting, the plot to kidnap Governor Gretchen Whitmer, and a man’s livestreamed beheading of his father last year were all fueled by conspiracy theories. But while the headlines suggest that conspiratorial thinking is on the rise, this is not the case.

Research points to no increase in conspiratorial thinking. Still, to a more dangerous reality: the conspiracies taking hold and being amplified by political ideologues are increasingly correlated with violence against particular groups. Fortunately, promising new research points to actions we can take to reduce conspiratorial thinking in communities across the U.S.

Some journalists claim that this is “a golden age of conspiracy theories,” and the public agrees. As of 2022, 59% of Americans think that people are more likely to believe in conspiracy theories today than 25 years ago, and 73% of Americans think conspiracy theories are “out of control.” Most blame this perceived increase on the role of social media and the internet.

But these headlines misunderstand the crisis: belief in conspiracy theories is not on the rise. Dr. Joseph Uscinski, an expert on conspiracy theories at the University of Miami who has tracked their prevalence and effects for close to two decades, finds no increase in levels of conspiratorial thinking.

Others echo his findings: a study by Uscinski and researchers from the U.S. and UK found no increase in conspiratorial beliefs in the U.S. (or in six European countries, for that matter) from the 1960s through 2020.

For instance, only about 5% of Americans believe in Q-Anon, and positive feelings towards Q-Anon have not increased since 2018. In fact, belief decreased rather than increased in most of the conspiracy theories examined. Most conspiracy theories pop up and burn out quickly. Those that take hold for a number of years are the exception.

What is growing is the link between believing in conspiracies and justifying or committing violence against particular groups or political opponents. A 2024 study found that between 2012 and 2022, the correlation between support for political violence and conspiratorial thinking tripled in magnitude — but researchers don’t know why. Researchers do know that “fringe” conspiracy beliefs — less popular beliefs held by more homogenous groups — tend to correlate more strongly with political violence.

Specifically, Holocaust denialism and false flag theories (conspiracies that suggest that attacks or events were staged by one group and pinned on another, such as that school shootings are staged by professional actors) are particularly strongly correlated with support for political violence.

Experts suggest that this growing link is perhaps due to violent people more often turning to conspiracies to justify their violent actions. Committing violence may not be such a leap for Holocaust deniers who are already willing to entertain violent thoughts outside the mainstream. Meanwhile, violent individuals might believe they are justified in acting on false flag conspiracies when those beliefs are normalized and amplified by political ideologues — as with assertions that the FBI perpetrated the January 6th insurrection.

Conspiratorial thinking doesn't make people violent. Instead, it directs violent people towards particular targets, channeling violence against groups like Jews, Muslims, and the LGBTQ+ community. The 2017 Charlottesville protesters, decrying “Jews will not replace us,” echoed the Great Replacement Theory and Jewish world domination conspiracies.

Conspiracies have also become a justification for militant Accelerationists, a group that advocates destroying economic, political, and societal systems to hasten the downfall of societies and rebuild them in their image. In the 2018 Tree of Life Shooting, the assailant killed 11 congregants because he believed the synagogue was systematically bringing in immigrants to replace White Americans.

Additionally, as seen in the examples above, attitude generalization causes prejudice against one group — say, from a conspiracy theory focused on Jews — to increase prejudice towards other groups, such as Asians, Muslims, and the LGBTQ+ community.

Encouragingly, some successful interventions are emerging. Promising new research had people who believe in conspiracies discuss their beliefs with artificial intelligence, large language models. Participants knew they were interacting with AI, and yet the interaction reduced belief in their chosen conspiracy theories by 20%, with the effect lasting at least two months. This debunking even spilled over into participants’ belief in other conspiracies, leading to a general decrease in conspiratorial thinking.

That makes sense: Conspiratorial thinking is more of a belief system (i.e. blaming secret plots spearheaded by elites or malign groups to explain events in opposition to evidence presented by bodies of experts), rather than a belief in just one conspiracy. Interestingly, receiving information from an AI bot may work better than human interventions, because believers feel judged by people, get defensive, and dig in. With an AI bot, they can ask for and receive facts without the emotions that come from feeling attacked. This might cause participants to be less defensive, perceive less bias, and use more analytical thinking.

Additionally, researchers found that having one to four strong social connections reduces the likelihood of supporting or engaging in political violence. Work in other areas of targeted violence suggests that family intervention encourages change in these beliefs.

Methods such as these could prove effective for changing the minds of those who believe in conspiracy theories and keeping those who hold violent conspiracies from taking the next step into action. Combined with this promising new AI intervention, there may be a real chance to blunt the impact of conspiracy theories on targeted groups.
