Science vs. Spin

Every day, headlines claim that science has proven something extraordinary, but how often do those claims accurately reflect the research? In this episode of Science vs. Spin, we examine how scientific findings become exaggerated, why correlation is frequently mistaken for causation, and how statistics can be used to make weak evidence appear convincing. From misleading health headlines to the psy...

Can regular sauna bathing actually extend your life, or are popular longevity claims getting ahead of the science? We examine research frequently discussed by health scientist Rhonda Patrick, including studies linking sauna use with lower cardiovascular mortality and longer life expectancy. Discover what the evidence supports, what remains uncertain, and why correlation is not the same as causatio...

You’ve probably seen the headline: exercise can be just as effective as antidepressants for treating depression. It is an appealing claim, especially as research increasingly demonstrates important mental-health benefits from physical activity. But comparing exercise with antidepressant medication is considerably more complicated than comparing two numbers from a clinical trial. In this episode of...

You’ve probably heard that childhood trauma “rewires the brain,” but what does that phrase actually mean? Brain-imaging studies have found differences associated with childhood adversity, yet those findings are often more complicated than popular headlines suggest. In this episode of Science vs. Spin, we separate what neuroscience has actually discovered from what the evidence cannot yet prove.

Biomarkers are sold as the future of medicine — earlier diagnoses, personalized treatment, objective tracking of disease — but the science behind that promise is shakier than the marketing suggests. This episode pulls apart where biomarkers genuinely help versus where they fail to predict what actually matters: quality of life and long-term survival. The gap is even wider in psychology and psychia...

Self-surveys dominate psychology and social psychology because they are cheap and easy to administer. The correct question is not whether people can answer Likert items, but whether those answers remain comparable across people, groups, or decades and whether the resulting scores correspond to anything that actually matters.

Food marketing does not always require a false statement to mislead consumers. By emphasizing one beneficial nutrient while withholding information about quantity and competing food sources, advertisers can make an ordinary product appear nutritionally exceptional. This article examines how cherry-picking, selective framing, and the health-halo effect shape what consumers believe about food.

Carlos talks with Dr. Brown about how flawed studies make it into publication and, from there, into headlines people trust. The conversation digs into common red flags — small sample sizes, p-hacking, conflicts of interest, and cherry-picked data — that separate rigorous science from spin dressed up as research. It's a practical guide to reading a study more critically before believing the claim b...

This episode examines the controversial diagnostic history and neuroscientific claims surrounding Dissociative Identity Disorder, pitting popular trauma-model narratives against rigorous scientific scrutiny. We analyze the strength of current neuroimaging evidence, evaluate methodological limitations in clinical studies, and explore how media portrayals and institutional biases can inflate diagnos...

Popular trauma narratives claim that chronic stress reshapes the brain and body in ways that inevitably impair focus, flexibility, and emotional control while damaging physical health. This episode examines the evidence behind those claims, separating well-supported findings from oversimplified interpretations. We explore how neuroimaging, physiology, and animal research contribute to our understa...

Across decades of public health data, researchers have noticed a stunning trend: as global education rates climb, age-adjusted dementia numbers are beginning to drop. This episode breaks down the complex longitudinal studies tracking how even a single additional year of schooling correlates with a significantly delayed onset of cognitive decline. We analyze the variables at play, investigating whe...

Recent epidemiological data shows a devastating rise in aggressive, early-onset cancers among adults who experienced metabolic dysfunction before age 30. This episode examines the precise biomolecular pathways—including hyperinsulinemia, altered cytokine signaling, and chronic systemic inflammation—that accelerate tumor development in adipose tissue environments. Join clinical researchers as they...

This podcast evaluates the scientific evidence supporting and questioning the role of sunscreen in melanoma prevention, drawing on randomized controlled trials, observational studies, and meta-analyses while addressing key limitations. It examines the interplay between sunscreen use and vitamin D synthesis, presenting arguments for potential interference alongside real-world data indicating minima...

This podcast episode explores the use of surrogate endpoints versus patient-important clinical outcomes in medical and psychological research studies, highlighting their role in accelerating trials while cautioning against over-reliance. It presents advantages such as faster, less expensive studies alongside critical limitations, including frequent failures to predict real clinical benefit as seen...

We put the "obesity shrinks your brain" headlines under the microscope to separate causal reality from confounding variables. This episode navigates the neurodegeneration debate, questioning if the data holds up or if we're seeing another case of correlation being sold as causation. Join us as we strip away the spin to see what the evidence actually says about the relationship between weight and w...

In 2025, a viral study claiming that 95% of corporate AI pilots were failing sent the Nasdaq into a tailspin—but there was one problem: the math was 100% wrong. We join Rob Wiblin to dissect how a flawed report managed to hijack the global AI narrative and what the evidence actually says about the success of generative AI in the enterprise. Learn how to spot "data torture" and why the real story o...

A major 2026 review in the journal Carcinogenesis claims nicotine vapes are “likely” to cause lung and oral cancers based on DNA damage, inflammation, and mouse tumors. Public-health experts on the other side call the paper misleading, arguing vaping remains far safer than smoking and a proven tool for quitting. We examine both arguments, expose the limitations of the studies on each side, and end...

This episode examines the heated debate between the Cochrane Review and The Lancet on anti-amyloid drugs for Alzheimer’s. We break down the modest benefits, real risks, and methodological differences between older and newer treatments. A balanced, evidence-based analysis for patients, families, and clinicians seeking clarity on this controversial topic.

In this episode, we examine the “Rat Study Problem” — the persistent challenge in biomedical research where treatments that succeed dramatically in mice frequently fail when tested in humans. The discussion explores biological differences in metabolism, immune response, disease progression, and environmental factors that limit the predictive value of rodent models. It highlights the high cost of t...

Most people consume scientific research through headlines—but those headlines often distort study design, exaggerate results, and hide critical limitations like small sample sizes, animal models, and surrogate markers. In this episode, we break down the most common ways research is misrepresented in the media, including the misuse of relative risk, correlation vs. causation errors, and misleading...
