What-the-Hell Effect
The what-the-hell effect is the cognitive process by which a single perceived dietary transgression gets reframed as evidence that the entire day — or entire diet — is now 'ruined.' Once reclassified as already failed, the psychological cost of continuing to eat is perceived as zero, removing any motivation to stop. Coined by Polivy and Herman in the 1980s, the effect explains why the size of the initial slip is often uncorrelated with the size of the subsequent binge: the magnitude of the binge is driven by the reclassification, not by the transgression itself.
How it sounds in your head
The inner script: 'I already had the cookie — the day is ruined anyway, might as well finish the whole bag and start fresh tomorrow.' The research reads it differently: the day is not an accounting unit that can be 'ruined' by a single item. The reclassification is the mechanism, not a rational description of reality — and catching it by name is the first interruption point.
