Psychologists call it the ‘what-the-hell effect’: when someone slips on a goal, like eating one cookie on a diet, they feel doomed and binge the whole jar.

A closer look

Ever eaten one cookie and thought, “Well, I’ve ruined the day—might as well eat the whole box”? That mental trap has a name: the *what-the-hell effect.* One mistake convinces the brain all progress is lost, which ironically creates bigger setbacks. But here’s the mind-bending twist: stopping to treat failure as feedback dissolves the spiral. Imagine a GPS—when you take the wrong turn, it doesn’t say, “Forget it, journey over!” It just reroutes. When failures become chapters instead of dead ends, your goals stop feeling like fragile glass and start feeling like ongoing adventures.
