Global Health Myths Persist: Quarter of Population Endorses Harmful Claims

Context The 5th annual Edelman Trust Barometer Special Report: Trust and Health, an observational survey, examined global public perceptions of health. This assessment encompassed 16,009 respondents across 16 countries, with roughly 1,000 individuals surveyed per nation. The study reports a global margin of error of plus or minus 1 percentage point and a country-specific margin of error of plus or minus 4.1 percentage points.

Key Facts Globally, 25% of people believe that raw milk is healthier than pasteurized milk, that acetaminophen use during pregnancy causes autism, and that vaccines are used for population control. More broadly, 70% of individuals worldwide hold at least one health belief contradicting medical science. In the United States, 86% of respondents reported perceiving the country as divided over health issues, a figure higher than in any other surveyed nation.

What It Means These findings indicate a notable disconnect between public beliefs and scientific consensus. Experts suggest that political polarization, intensified by discussions around health policy such as the Affordable Care Act and amplified during the COVID-19 pandemic, correlates with the spread of health misinformation. Such divisive health beliefs appear across various demographics, including age, political affiliation, and educational backgrounds, with higher prevalence among younger respondents and those with right-leaning political views. Despite the prevalence of these myths, the survey highlights a crucial point of leverage: 80% of respondents trust their doctor as a source of health information, while 73% trust medical scientists. This suggests direct engagement with trusted medical professionals offers a path to accurate information delivery.

What to watch next Future efforts will focus on how health communication strategies adapt to address pervasive misinformation, leveraging trusted medical sources to bridge the divide between public perception and scientific understanding.
