Do you check the professional credentials of doctors you follow on social media?
Researchers analyzing content from doctor-influencers on TikTok discovered that followers rarely check professional credentials. The study, published in the Journal of Consumer Affairs, highlights how visual cues influence user perception.
Why it matters
Young followers frequently accept medical advice from influencers based solely on visual markers like scrubs, name badges, and stethoscopes. This trend indicates that surface-level credibility signals often override traditional professional verification methods.
Analysis of 330 TikTok videos revealed that posts featuring doctors in scrubs or lab coats received an average of 1,150 comments, significantly higher than the 170 comments seen on posts featuring doctors in casual clothing.
