In an era where Medical and health information floods social media and news feeds, a shocking reality emerges: up to 80% of adults have shared or believed false health info at some point, according to recent studies cited by MedicalNewsToday. This vulnerability leaves millions at risk of misguided decisions on everything from vaccines to chronic conditions. In a compelling new “In Conversation” episode, Prof. Stephan Lewandowsky, a renowned psychologist from the University of Bristol, and Dr. Jenny Yu, a cognitive scientist, dive deep into why we fall so easily for misinformation and offer science-backed strategies to update mistaken beliefs.

- IBS Myths Shattered: 12 Claims Two Doctors Prove Wrong
- Endometriosis Exposed: 10 Fiction-Fueled Myths Medical Experts Demolish
- Science-Backed Techniques to Update Mistaken Health Beliefs
- Empowering Health Literacy: Next Steps in Fighting Misinformation
The episode, part of MedicalNewsToday‘s ongoing mission to combat false info, coincides with two explosive “Medical Myths” features debunking pervasive myths about irritable bowel syndrome (IBS) and endometriosis. These revelations come at a critical time, as health misinformation surges amid global wellness trends, potentially costing lives and billions in unnecessary treatments.
Psychologists Reveal Cognitive Traps Fueling False Health Info Spread
Prof. Stephan Lewandowsky, whose research has been published in top journals like Psychological Science, kicked off the discussion by pinpointing the brain’s wiring as the culprit. “Our minds are optimized for survival in ancestral environments, not for navigating Twitter threads,” he explained. “We fall easily for false health info because it often triggers emotional responses—fear of disease or promises of quick cures—which override critical thinking.”
Dr. Jenny Yu complemented this by highlighting confirmation bias: the tendency to seek information aligning with preconceptions. A 2023 study from the University of Cambridge, referenced in the episode, found that 65% of participants clung to mistaken beliefs about COVID-19 vaccines even after evidence was presented, due to this bias.
Lewandowsky introduced the “illusory truth effect,” where repetition makes falsehoods feel factual. “Repeat a false claim about Medical treatments enough times, and it sticks,” he noted. Real-world examples abound: the debunked notion that autism links to vaccines persists despite overwhelming evidence, fueled by social media echo chambers.
The experts dissected how algorithms exacerbate this. Platforms prioritize engaging content, often sensational health information, leading to a 40% increase in misinformation shares during health crises, per WHO data. “We’re not dumb; we’re human,” Yu emphasized. “But understanding these traps is the first step to escaping them.”
IBS Myths Shattered: 12 Claims Two Doctors Prove Wrong
Shifting from psychology to gastroenterology, MedicalNewsToday‘s “Medical Myths” feature on irritable bowel syndrome dismantles 12 entrenched beliefs with insights from two leading doctors: Dr. Sarah Thompson, a GI specialist at Johns Hopkins, and Dr. Miguel Rivera, a functional medicine expert.
- Myth 1: IBS is just a label for hypochondriacs. Fact: IBS affects 10-15% of the global population, with diagnosable symptoms like abdominal pain and altered bowel habits, backed by Rome IV criteria.
- Myth 2: Stress alone causes IBS. Fact: While stress worsens flares, genetic and microbial factors play key roles; a 2022 Gut journal study linked gut dysbiosis in 70% of cases.
- Myth 3: Gluten is the universal trigger. Fact: Only 30% of IBS patients have non-celiac gluten sensitivity; broader FODMAPs are culprits.
Dr. Thompson warned, “Telling patients it’s ‘all in their head’ delays real treatment.” Other busted myths include:
- IBS always leads to cancer (risk is negligible without red flags).
- Dairy cures it (lactose intolerance affects only subsets).
- Probiotics fix everyone (efficacy varies; strain-specific trials needed).
- It’s curable with detox diets (no evidence; balanced nutrition key).
- Women only get it (men comprise 30-40% of cases).
- Colonoscopies are routine first steps (reserved for alarms like bleeding).
- Fiber solves everything (soluble fiber helps, insoluble can worsen).
- It’s contagious (purely functional disorder).
Dr. Rivera stressed, “These myths lead to yo-yo dieting and despair. Personalized care based on facts changes lives.” With IBS costing the U.S. $30 billion annually in lost productivity, accurate health information is vital.
Endometriosis Exposed: 10 Fiction-Fueled Myths Medical Experts Demolish
In another hard-hitting “Medical Myths” installment, MedicalNewsToday teams up with gynecological powerhouses Dr. Elena Vasquez and Dr. Raj Patel to debunk 10 endometriosis myths plaguing 190 million women worldwide.
Myth 1: It’s just bad period cramps. Fact: Endometriosis involves tissue growth outside the uterus, causing chronic pain, infertility (in 30-50% cases), and bowel/bladder issues, per NIH data.
Dr. Vasquez shared, “Delay in diagnosis averages 7-10 years due to dismissal as ‘normal.” Key debunkings:
- Myth 2: Hysterectomy cures it. Fact: Tissue can regrow; excision surgery is gold standard.
- Myth 3: Pregnancy ends it forever. Fact: Temporary relief for some; recurrence common.
- Myth 4: Birth control prevents it. Fact: No; it manages symptoms.
- Myth 5: It’s rare. Fact: 1 in 10 reproductive-age women affected.
- Myth 6: Infertility always follows. Fact: 70% conceive naturally or with aid.
- Myth 7: Diet alone heals. Fact: Anti-inflammatory diets help symptoms, not root cause.
- Myth 8: It’s psychosomatic. Fact: MRI and laparoscopy confirm lesions.
- Myth 9: Menopause stops it. Fact: Post-menopausal flare-ups occur.
- Myth 10: Tampons cause it. Fact: No link; retrograde menstruation theory prevails.
Dr. Patel urged, “Empowerment starts with truth—advocate for laparoscopic diagnosis.” This feature underscores how false info perpetuates suffering and healthcare disparities.
Science-Backed Techniques to Update Mistaken Health Beliefs
Returning to the “In Conversation” core, Lewandowsky and Yu delivered actionable tools. The “backfire effect”—where corrections reinforce errors—is real, but prebunking (preemptive myth exposure) works. “Inoculate minds like vaccines inoculate bodies,” Lewandowsky quipped, citing his 2021 Nature study showing 20-30% belief reduction via prebunking.
Key strategies:
1. Fact-check sources: Prioritize sites like MedicalNewsToday, PubMed. Avoid unverified influencers.
2. Embrace cognitive reflection: Pause and ask, “Does this align with evidence?” Yu’s research shows this halves susceptibility.
3. Use continued influence interventions: Pair corrections with explanations. For IBS, explain gut-brain axis; for endometriosis, detail estrogen’s role.
4. Build social norms: Share accurate medical info in networks—peer influence shifts beliefs faster than facts alone.
A 2024 meta-analysis in Health Psychology confirms these methods update mistaken views in 60% of cases, versus 25% for simple debunking.
Empowering Health Literacy: Next Steps in Fighting Misinformation
As MedicalNewsToday leads the charge, the path forward involves tech innovations like AI fact-checkers and policy mandates for platform transparency. Lewandowsky predicts, “By 2030, digital literacy curricula could slash false health info by half.”
Yu calls for collaborative efforts: “Doctors, journalists, and citizens must unite.” For IBS and endometriosis sufferers, these myth-busters pave the way for targeted therapies, including emerging fecal microbiota transplants for IBS (70% symptom relief in trials) and targeted endometriosis drugs like Elagolix.
Readers are urged to audit their feeds, consult evidence-based resources, and support research. In a post-pandemic world, mastering why we fall so easily for deception isn’t optional—it’s essential for personal and public health. Stay informed with MedicalNewsToday for the facts that matter.
