In an era where misinformation spreads faster than viruses, a new MedicalNewsToday episode reveals why people fall so easily for false health info. Featuring Prof. Stephan Lewandowsky and Dr. Jenny Yu, the “In Conversation” podcast dissects the psychology behind our vulnerability to Medical myths and offers strategies to update mistaken beliefs. Meanwhile, the site’s latest Medical Myths features tackle 12 claims about irritable bowel syndrome (IBS) and 10 about endometriosis, separating fact from fiction with expert input.

Psychologists Unpack the Brain’s Susceptibility to False Medical Information
Prof. Stephan Lewandowsky, a cognitive psychologist from the University of Bristol, explains that humans are wired to prioritize emotionally charged or familiar narratives over dry facts. “We fall easily for false info because our brains favor coherence over accuracy,” he states in the episode. This phenomenon, known as the “illusory truth effect,” makes repeated falsehoods feel true over time.
Dr. Jenny Yu, a health communication specialist, adds that social media algorithms exacerbate this. A 2023 study cited in the podcast found that 62% of health information shared on platforms like Facebook contains inaccuracies, with viral posts garnering 10 times more engagement than corrected versions. During the COVID-19 pandemic, false claims about vaccines reached billions, leading to hesitancy rates as high as 30% in some demographics.
Lewandowsky highlights the “backfire effect,” where confronting mistaken beliefs can entrench them further. “Simply debunking doesn’t work; you need to provide a compelling alternative narrative,” he advises. The episode draws on Lewandowsky’s research, including a 2022 paper in Psychological Science, showing that pre-emptive corrections reduce belief in falsehoods by 25%.
Real-world examples abound: the myth that “sugar causes hyperactivity” persists despite decades of evidence to the contrary, influencing parental behaviors and product marketing. MedicalNewsToday’s analysis underscores how such false health info delays proper care, costing healthcare systems millions annually.
12 Irritable Bowel Syndrome Claims Debunked by Gastroenterology Experts
In the first Medical Myths feature, two gastroenterologists scrutinize 12 prevalent IBS assertions. IBS affects up to 15% of the global population, yet misconceptions hinder effective management.
- Myth 1: IBS is just stress-related. Fact: While stress worsens symptoms, IBS stems from gut-brain axis dysfunction, altered microbiota, and inflammation, per a 2024 Gut journal review.
- Myth 2: It’s always caused by food intolerances. Truth: Only 30-50% of cases link to FODMAPs; genetic factors play a larger role.
- Myth 3: Antibiotics cure IBS. Debunked: They disrupt microbiome balance, potentially aggravating symptoms, as shown in a NIH-funded trial.
- Myth 4: Colon cancer risk is higher in IBS patients. No evidence supports this; routine screening follows age-based guidelines.
- Myth 5: Gluten-free diets fix everyone. Effective for 10-20% with celiac overlap, but unnecessary for most.
Continuing the list, experts dismiss claims like “probiotics cure IBS overnight” (they help mildly, with 20-30% improvement rates) and “it’s psychosomatic” (validated biomarkers exist). Dr. Sarah Thompson, one gastroenterologist, notes, “These myths lead to self-treatment failures; evidence-based therapies like low-FODMAP diets and CBT yield 70% symptom relief.”
The feature references a meta-analysis of 50 studies, revealing that 40% of IBS patients delay diagnosis due to misinformation. MedicalNewsToday emphasizes personalized care, urging readers to consult professionals for Rome IV criteria-based diagnosis.
Endometriosis Facts vs. Fiction: 10 Myths Shattered by Specialists
Endometriosis impacts 10% of reproductive-age women, causing chronic pain, yet diagnosis takes 7-10 years on average due to entrenched myths. MedicalNewsToday’s second feature features gynecologists debunking 10 falsehoods.
- Fiction: It’s just bad period pain. Reality: Tissue growth outside the uterus leads to adhesions and infertility in 30-50% of cases.
- Myth: Pregnancy cures it. Temporary relief for some, but recurrence is common post-partum.
- Falsehood: Hysterectomy is always the fix. Removes uterus but not ectopic tissue; excision surgery is gold standard.
- Myth: It’s rare. Affects 190 million worldwide, per WHO.
- Claim: Birth control prevents it. Suppresses but doesn’t eradicate.
Further myths include “it’s psychosomatic” (MRI and laparoscopy confirm lesions) and “diet alone heals it” (anti-inflammatory diets aid symptoms, not cure). Dr. Maria Lopez states, “Misinformation silences patients; we need better education to cut diagnostic delays.” A 2023 Lancet study links myths to undertreatment, with only 20% receiving adequate pain management.
The article integrates patient stories, like a 32-year-old who endured 12 years of dismissal before laparoscopic confirmation, highlighting systemic issues.
Strategies from Experts to Update Mistaken Health Beliefs Effectively
Returning to the podcast, Lewandowsky and Yu provide actionable tools to combat vulnerability. “Crowdsource truth: Check multiple reputable sources,” Yu recommends, pointing to MedicalNewsToday as a model for evidence-based health information.
Key techniques include:
- Prebunking: Learn myth patterns before exposure; reduces uptake by 20%, per Cambridge research.
- Fact-checking habit: Use tools like Snopes or Health Feedback; apps flag 80% of viral fakes.
- Belief revision: Replace myths with vivid alternatives, e.g., visualize IBS biomechanics over stress cartoons.
- Social inoculation: Discuss with peers using “steel-manning” to strengthen arguments.
Lewandowsky’s lab experiments show these methods update mistaken views in 65% of participants. For IBS and endometriosis, the features link to resources like NICE guidelines and Endometriosis UK, promoting sustained learning.
Statistics paint urgency: A Pew survey found 53% of U.S. adults encountered health rumors weekly, with 25% believing them initially. MedicalNewsToday’s initiative aligns with WHO’s infodemic efforts.
MedicalNewsToday’s Push Shapes Future of Reliable Health Journalism
As digital noise intensifies, MedicalNewsToday‘s blend of expert interviews, myth-busting, and psychological insights positions it as a beacon for trustworthy medical content. Future episodes promise coverage of vaccine hesitancy and AI-generated health fakes.
Experts call for policy: Yu advocates platform accountability, while Lewandowsky pushes science literacy in schools. Readers are encouraged to subscribe for updates, join webinars, and share verified info. By empowering individuals to discern truth, these efforts could slash misinformation’s health toll, fostering a more informed public ready to navigate wellness challenges ahead.
