The early bird gets the worm. What goes around, comes around. It’s always darkest just before dawn. We carry these little nuggets of wisdom—these adages—with us, deep in our psyche. But recently we started wondering: are they true? Like, objectively, scientifically, provably true?

So we picked a few and set out to fact check them. We talked to psychologists, neuroscientists, runners, a real estate agent, skateboarders, an ornithologist, a sociologist and an astrophysicist, among others, and we learned that these seemingly simple, clear-cut statements about us and our world, contain whole universes of beautiful, vexing complexity and deeper, stranger bits of wisdom than we ever imagined.
