Not really a surprise here, but some research concluded that people who believe in mind-body dualism are less concerned about their body’s health than people who don’t.
Across five related studies, researchers Matthias Forstmann, Pascal Burgmer, and Thomas Mussweiler of the University of Cologne, Germany, found that people primed with dualist beliefs had more reckless attitudes toward health and exercise, and also preferred (and ate) a less healthy diet than those who were primed with physicalist beliefs.
Furthermore, they found that the relationship also worked in the other direction. People who were primed with unhealthy behaviors — such as pictures of unhealthy food — reported a stronger dualistic belief than participants who were primed with healthy behaviors.
Overall, the findings from the five studies provide converging evidence demonstrating that mind-body dualism has a noticeable impact on people’s health-related attitudes and behaviors. Specifically, these findings suggest that dualistic beliefs decrease the likelihood of engaging in healthy behavior.
