The Psychology of People

Why does one chorus loop in your mind for hours, even when you never chose to play it? This episode explores new 2025 research suggesting earworms may be more than random musical annoyances. They may be a form of mental habit, connected to everyday loops like tapping, counting, checking, rehearsing, and repeating. This episode was generated with AI assistance.

Daniel Kahneman's peak-end rule reveals that our brains don't average experiences—they take snapshots of the most intense moment and the final moment, then discard everything else. A 2022 meta-analysis of 174 studies confirms this effect is large and robust, explaining why a colonoscopy that ends gently feels better than a shorter one that stops abruptly, and why that vacation where everything went wrong except the final sunset still glows in memory.

Scientists at Duke-NUS Medical School have discovered a direct mechanism linking gut bacteria to anxiety. When certain bacteria metabolize food, they produce molecules called indoles that travel to the brain's fear center and dial down anxiety. This research opens the door to treating mental health with probiotics instead of traditional medications. This episode was generated with AI assistance.

For two decades, psychology taught that willpower was like a muscle that could be depleted—and restored with a glass of lemonade. Then came the replication crisis, and the elegant theory collapsed. This episode explores what the ego depletion saga teaches us about decision fatigue, the power of belief, and why your experience of mental exhaustion may have more to do with your mindset than your glucose levels. This episode was generated with AI assistance.

A nine-year longitudinal study reveals that passive social media scrolling doesn't just correlate with loneliness—it creates a self-reinforcing cycle that's remarkably difficult to break. Researchers tracked nearly 7,000 adults and discovered what they call the 'loneliness loop': lonely people turn to social media to address their feelings, but the scrolling intensifies their isolation.

For 150 years, neuroscience told us neurons were the only cells that mattered for memory and emotion. Astrocytes? Just support staff - 'nerve glue.' A groundbreaking 2026 Nature study just proved that story completely wrong. These overlooked cells don't just support fear memories - they actively create them, help recall them, and critically, help extinguish them. This changes everything about how we might treat PTSD, anxiety, and phobias. This episode was generated with AI assistance.

Researchers at the University of Pennsylvania have identified a new cognitive phenomenon they call 'cognitive surrender'—our tendency to accept AI-generated answers without critical evaluation.

This episode explores why lonely people often push away the very connections they desperately need. This episode was generated with AI assistance.

New research published in March 2026 found that cannabis users in controlled conditions were significantly more likely to recall words that were never shown to them—essentially creating memories of events that didn't happen. This isn't about forgetting; it's about the brain actively constructing experiences that feel real but aren't. The implications extend far beyond cannabis policy into fundamental questions about memory reliability. This episode was generated with AI assistance.

A decade ago, headlines declared psychology broken: only 25-39% of classic studies could be replicated. The field's credibility seemed destroyed. But here's what happened next: a remarkable, data-driven redemption. Sample sizes have tripled. Barely-significant results have plummeted. Preregistered studies now replicate at nearly 90%. This episode tells the story of how psychology's most public failure became a model for scientific self-correction — and what it reveals about how knowledge actually advances.
