Do Conspiracy Theories Get More And More Prevalent Over Time?

The public is increasingly convinced that beliefs in conspiracy theories are increasing, and many scholars, journalists, and policymakers agree. Conspiracy theories are explanations of certain events or situations through theories based on data not officially recognized and generally induced by influential individuals. These theories are positively associated with nonnormative behaviors, including participation in criminal acts and destructive political movements. However, little evidence has been provided to demonstrate that beliefs in conspiracy theories have increased over time.

In all four analyses, the researchers found no statistically significant evidence that beliefs in conspiracy theories have increased over time. A greater number of beliefs in specific conspiracy theories were found. Additionally, conspiracy theories drive people to reject scientific consensuses, most notably the consensus around anthropogenic climate change.

Recent events, such as the election of Donald Trump, the U.S. Capitol riot, and several conspiracy theory-inspired mass shootings, have prompted people to believe in grand conspiracies. However, this feeling is not supported by the evidence. Conspiracy theories cover everything from paranormal theories to conspiracies to explain wars, diseases, or scientific discoveries. A new study has found no evidence that people’s beliefs in conspiracy theories increase over time.

Research has produced a significant body of knowledge about the antecedents and consequences of individual differences in belief in conspiracy theories. The approach to patients with conspiracy beliefs should be similar to dealing with psychotic disorders. The profusion of conspiracy theories in recent social and political discourse is alarming, and as a response to this increasingly concerning issue, there is a need for more research and understanding of the factors contributing to conspiracy beliefs.
