A study of 3,958 Korean-language medical YouTube videos found that clickbait-heavy and dramatic formats attracted more views, likes, and comments than videos with more reliable medical information. Researchers measured engagement across those 3,958 videos and reported higher viewership and interaction for attention-grabbing thumbnails, titles, and presentation styles. The analysis showed that accuracy and evidence-based content did not correlate with the higher engagement metrics that the popular videos received. Researchers warn that YouTube’s attention-rewarding dynamics can bury higher-quality medical information in favor of sensational formats, increasing the risk that audiences encounter less reliable health guidance.
