Claim: Do 7 in 10 people worldwide believe at least one debunked health myth?

The claim that 7 in 10 people worldwide believe at least one debunked health myth is mostly true. A report from the Edelman Trust Barometer indicates that this statistic holds across various demographics. However, some studies suggest that belief in specific myths can vary significantly and may not represent a global consensus. Critics argue that localized studies do not provide a comprehensive view of worldwide beliefs regarding health myths, which adds complexity to the claim's validity. The models diverge sharply — treat this as higher-uncertainty. Perplexity comes in highest (85%), while Gemini is lowest (50%). Perplexity expresses higher confidence than Gemini on this claim. While the Edelman Trust Barometer supports the claim, some studies, such as one published in PLOS ONE, indicate that belief in health myths can vary widely depending on demographics and specific contexts. These studies focus on particular populations and do not provide global data on the prevalence of belief in debunked health myths. This discrepancy suggests that while the claim may be generally accurate, it lacks comprehensive evidence across all populations, leading to some uncertainty about its universal applicability.
