Signal &amp; Noise is about the gap between what research actually shows and what headlines claim it shows. In an information environment where every study becomes a definitive claim, the ability to evaluate evidence isn&#39;t academic it&#39;s a survival skill. Each episode decodes one aspect of how science works, how it fails, and how to navigate both without becoming either credulous or cynical.

The placebo effect is often dismissed as &#39;just in your head.&#39; Modern neuroscience has demonstrated that this is both true and deeply misleading. Placebos produce measurable physiological changes real endorphin release, real neurological activity, real immune modulation. Ted Kaptchuk&#39;s open-label placebo trials (where patients know they&#39;re taking placebos) showed significant improvement in IBS symptoms. This episode explores what the placebo effect actually reveals about mind-body integration.

Placebos produce real endorphin release, real dopamine activity in Parkinson&#39;s patients, and real immune modulation. Ted Kaptchuk&#39;s Harvard trials showed improvement even when patients were told explicitly they were taking sugar pills. This episode explains the neuroscience, why &#39;just in your head&#39; is a profound understatement, and what the placebo effect tells us about the mind-body relationship.

The Placebo Effect Is Real: What It Tells Us About the Relationship Between Mind and Body

The map is not the territory Alfred Korzybski&#39;s foundational insight in general semantics describes the gap between our mental representations of reality and reality itself. This episode explores how mental models shape perception, how they fail under novel conditions, and what the science of expert performance reveals about how to build and update better ones.

Alfred Korzybski said the map is not the territory. Your mental models are useful compressions of reality built from experience and they fail exactly when conditions change most. This episode explains how experts&#39; rich mental models also create their largest blind spots, and what Philip Tetlock&#39;s superforecaster research identifies as the one practice that keeps predictions accurate over time.

SIGNAL &amp; NOISE is about how to think about evidence specifically the gap between what research actually shows and what headlines claim it shows. In an information environment where every diet study, psychology finding, and economic report is weaponized into a definitive claim, the ability to evaluate evidence is a survival skill. Each episode decodes one aspect of how science works, how it fails, and how to navigate both.

The cycle of contradictory health headlines isn&#39;t a science problem it&#39;s a communication problem. This episode gives you four questions that separate signal from noise in any study: Is it experimental or observational? What&#39;s the effect size? Has it replicated? Who funded it? Essential tools for navigating a research landscape where most headlines are missing the context you need.
