Knock on wood. Avoid black cats. Never walk beneath a ladder. But why?

Superstitions are some of humanity's oldest companions. Long before science could explain the world around us, our ancestors relied on patterns, rituals, and symbolic thinking to make sense of uncertainty. Even today, in an age of satellites and supercomputers, many of us still find ourselves crossing our fingers, tossing salt over a shoulder, or feeling just a little uneasy when the calendar reads Friday the 13th.

In this episode of Occam's Lantern, we explore where superstition comes from—not to mock it, nor to endorse it, but to understand it. Together we'll trace its roots through evolution, psychology, and history, examining why the human brain is so remarkably good at finding patterns... even when none exist.

Along the way we'll discuss probability, luck, cognitive biases, folklore, and the comforting illusion of control. Why do gamblers have rituals? Why do athletes refuse to change "lucky" socks? Why do entire cultures develop traditions around seemingly ordinary objects and events? And perhaps most importantly, why are these beliefs so persistent, even after we know better?

Rather than dismissing superstition as simple ignorance, we'll argue that it's something far more interesting: an unintended consequence of one of humanity's greatest evolutionary strengths—the ability to recognize patterns and prepare for the future.

Because perhaps the greatest trick superstition ever pulled wasn't convincing us that the universe was sending signs...

...but convincing us that we could decode them.

Join me as we separate coincidence from causation, folklore from fact, and discover why a little superstition may add flavor to life—even if it isn't secretly writing the rules behind the curtain.
