Award-winning medical journalist Deborah Cohen joins the Plutopia News Network to discuss her book Bad Influence: How the Internet Hijacked Our Health. Deborah examines how social media algorithms, influencers, podcasts, wellness brands, and AI tools have transformed the way people find and evaluate health information. She argues that online platforms reward certainty, emotion, and personal storytelling over scientific nuance, while commercial incentives increasingly shape what health advice reaches the public. The conversation explores the erosion of trust in traditional institutions, the rise of health influencers and wellness marketing, the promises and pitfalls of patient empowerment, the quantified-self movement, GLP-1 drugs, and the growing role of AI in medicine. Throughout, Cohen emphasizes the challenge of navigating a digital health ecosystem where expertise competes with attention, commercial interests, and algorithmic amplification, leaving patients to determine whom—and what—to trust.

Deborah Cohen:

Obviously, you want to sell newspapers — if you’re a mainstream media, you want to get eyeballs on the screens. But this is all monetized on social media. So if you have a video that goes viral, you potentially stand to gain financially. Also, a lot of influencers work with companies for product placement, to advertise products. And there’s a massive market in healthcare. So there was one study that suggested — and this is a couple of years old, it’s a US study — that there’s over 3 million health providers on TikTok alone. So, We’re getting our information from people very much with a commercial incentive to sell.
