In this episode, we unpack how TikTokers, WhatsApp aunty group chats, and everyone in between use social media for health advice. We explore how misinformation, overconfidence, and anti-intellectualism are turning opinions into “facts.” From TikTok doctors to vaccine myths, we ask when influencers replaced experts, why trust in science is collapsing, and who is actually paying the price.
