This podcast episode explores the research conducted by Professor Jonathan Mayer and his team on adapting security warnings to counter online disinformation. The study aimed to understand the effectiveness of different kinds of warnings for misinformation and bridge the gap between information security and online misinformation. The researchers conducted pilot and crowd worker studies, finding that interstitial warnings were more effective in guiding users towards trustworthy sources. However, the theories behind the effectiveness did not hold up, suggesting a need for further investigation. The episode also discusses the role of choice architecture in combating misinformation, the need for accountability in online services, and the limitations and opportunities in misinformation research.
