Susceptibility to cancer misinformation: Predictors of false belief and false memory formation

Abstract Previous research has shown that people sometimes come to believe in misinformation presented in the form of fake news, and even form false memories for the fabricated events described. This study aimed to investigate the effects of analytical reasoning, attitudes to complementary and alternative medicine, bullshit receptivity, and previous experience with cancer on the formation of false memory and false belief for cancer related misinformation. Participants ( N = 466) were exposed to four fake news stories and four true news stories relating to cancer treatment and services. Male gender, low analytical reasoning, receptivity to bullshit, and endorsement of complementary and alternative medicine were all significant predictors of belief in cancer misinformation, while participants with poor analytical reasoning or higher receptivity to bullshit reported more false memories for fake news stories. These results indicate that reflexive, intuitive thinking styles contribute to susceptibility to cancer misinformation, suggesting a potential target for public health interventions.
