Historical Humoral Medicine and Persistent Myths

Blaming our problems on the Moon is lunacy! Jessica Wynn illuminates the dark side of what we understand about our celestial neighbor on Skeptical Sunday.

Welcome to Skeptical Sunday, a special edition of The Jordan Harbinger Show where Jordan and a guest break down a topic that you may have never thought about, open things up, and debunk common misconceptions. This time around, we’re joined by writer and researcher Jessica Wynn!

On This Week's Skeptical Sunday:

• The Moon is history's greatest scapegoat — blamed for madness, bad moods, crime, and chaos for millennia. But it's not the Moon driving the weirdness. It's priming and confirmation bias working in tandem: one loads the mental gun, the other pulls the trigger.
• Tides are real and genuinely impressive — the Moon pulls Earth's oceans into two massive bulges simultaneously, creating predictable highs and lows that surfers, sailors, and scientists all rely on. But "humans are 60% water" does not extend the logic. Tidal forces operate at planetary scale, not cellular.
• Lunar myths have proven remarkably adaptive. We replaced "the Moon causes lunacy" with "the Moon charges my crystals" — different language, same fundamental misfire. Pseudoscience doesn't disappear; it just rebrands to match the cultural moment.
• Large-scale studies across emergency rooms, psychiatric wards, police records, maternity wards, and veterinary clinics consistently find no lunar effect on behavior. When researchers control for variables properly, the Moon's behavioral influence vanishes entirely.
• The Moon's actual résumé is staggering enough without the mythology. It formed from a cataclysmic planetary collision, stabilized Earth's axial tilt, and made complex life possible — and understanding what it genuinely does is far more empowering than crediting it for your bad week.
