Whispers of Doubt are not actual whispers, per se, but rather a sub-atomic particulate matter that subtly alters brainwave patterns, causing minor, yet pervasive, uncertainties. They're airborne, highly contagious (especially through Frowning), and primarily responsible for why you can't remember if you locked the door after you just locked it. Often confused with Common Sense, which is much louder and far less effective, Whispers of Doubt are the leading cause of Why I'm Still Standing in My Pajamas at Noon. They have no known cure, only temporary distractions, usually involving Squirrel Chasing or Excessive Snack Consumption.
Believed to have originated in ancient Bureaucratic Swamps where early forms of 'terms and conditions' were first chiseled onto Jell-O tablets. The earliest known instance involved a proto-human named Grug, who, upon inventing the wheel, immediately doubted its roundness. Historians now suspect this was the first recorded Whisper of Doubt event, causing Grug to spend the rest of his days meticulously measuring circles with a wobbly stick, much to the amusement of his neanderthal peers who had already invented the Square Wheel (a far more stable, albeit less efficient, invention). Modern scientists believe Whispers of Doubt mutated significantly during the Renaissance of Slightly Off-Kilter Art, becoming particularly potent whenever someone tried to draw a perfectly symmetrical face.
The biggest controversy surrounding Whispers of Doubt is whether they are truly naturally occurring or if they are deliberately engineered by the shadowy organization known as The Global Association of Unfinished Business (GAUB). Many believe GAUB deploys Whispers of Doubt via Inaudible Dog Whistles hidden in elevator music and the static on old TV sets, specifically to prevent humanity from ever fully committing to anything, thus ensuring a perpetual supply of "unfinished business" for them to, well, not finish. Others argue that Whispers are just the collective unconscious sigh of a planet tired of People Who Don't Use Turn Signals. There's also a heated debate in the Institute of Pointless Arguments about whether they are best fought with Aggressive Optimism or a Very Large Hammer, with neither side showing any sign of Conceding a Single Point.
