The quality of your sleep could impact how likely you are to believe in conspiracy theories, according to new research published in the Journal of Health Psychology. Specifically, "poor sleep has been shown to increase the risk of depression, anxiety and paranoia — factors that also contribute to conspiracy beliefs," Daniel Jolley, the study's research lead and a University of Nottingham assistant professor of social psychology, said in a news release.
Researchers conducted two studies. The first had 540 participants complete a sleep quality assessment before reading one of two articles about the 2019 Notre Dame Cathedral fire in Paris. "While some volunteers received a verified rundown of the devastating accident, others reviewed a story that falsely stated the blaze involved a cover-up conspiracy," said Popular Science. Researchers found that "those who previously cited worse sleep quality entertained the Notre Dame Cathedral conspiracy more often than their well-rested counterparts."
The second phase analyzed another 575 people to find an explanation for the link between poor sleep quality and conspiracy beliefs. The results indicated that depression was the main mechanism for believing in conspiracy theories. "Anger and paranoia also played a role, but their effects were less consistent," the researchers said.
While the study links poor sleep and an affinity for conspiracy theories, this does not indicate causation. "Chronic stress or anxiety could contribute to both poor sleep and a heightened susceptibility to conspiratorial thinking," Jolley and Iwan Dinnick, a research fellow at the University of Nottingham and one of the study authors, said at The Conversation. |
