Check the Simple Thing First
A playful groove song about Occam's razor, checking the simple explanation before chasing an elaborate one when two ideas both explain the same mystery.
The nightlight flickered, once, then twice, and Nora sat up, eyes like ice: "There's a ghost, living in the wall, tapping the switch, small and tall!"
Her brother Theo grinned into the dark, "It's a ghost, a ghost AND a shark that swam through the pipes from the sea somehow, and joined a raccoon gang, here and now."
Check the simple thing first Before the wild story, before the worst When two ideas both explain the same The simple one usually wins the game
The theories grew as the two kids talked -- a ghost, a shark, then a wizard who walked through the wall with a wand made of light, casting flicker spells every night.
Dad walked in, heard the wild tale: "Ghosts and sharks and wizards, quite a sail -- before we sail that story far and wide, let's check the simple thing, right here inside."
Dad picked up the nightlight, turned it round, wiggled the bulb, gave it a small pound. The flicker stopped. He held it to the light: "See this? The bulb was loose, not tight."
No ghost, no shark, no wizard's wand -- only a bulb that had wiggled and gone loose. Screwed back snug, the flicker was through -- the simple fix was tried and true.
A wise thinker had a rule for this, long, long ago, and it's hard to miss: "Do not pile up reasons in a row -- check the simple guess first, before you go."
They called it a razor, sharp and clean, cutting away the wild, in-between -- simple isn't always true, but it's the first good guess to pursue.
It is not that magic never happens, true, or that wild ideas never break through -- only that the simple guess deserves first look, before you write the wizard in your book.
Nora smiled, put her ghost tale away, kept it for stories, not for today. Next time something strange gives you a fright, check the simple thing first, then sleep tight.
