Self-Signaling
Self-signaling is the theory that people learn who they are from watching their own actions, the same way they'd judge a stranger — which is why a single skipped morning can feel like evidence, not just an event.
Self-signaling is the idea that people don’t have direct access to their own character — their willpower, their discipline, their follow-through — and so they infer it the same way they’d infer a stranger’s: from watching what that person actually does.
The term comes from economists Ronit Bodner and Drazen Prelec, who argued in a 2003 paper that every choice carries two kinds of value: the ordinary payoff of the choice itself, and a second, separate payoff in what the choice tells you about who you are. Skip a run and the loss isn’t just the workout. It’s a small, private piece of evidence that you’re the kind of person who skips. Bodner and Prelec called this second payoff “diagnostic utility,” and it’s why a single missed morning can feel disproportionately heavy: the ten minutes lost are trivial, but the self-diagnosis isn’t.
This is also why a witness changes the math. An unwitnessed lapse is evidence you can quietly discount — nobody saw it, so it’s easier to treat as a fluke rather than a data point. A witnessed one is harder to explain away, if only to yourself, which is the actual mechanism a lot of accountability tools are leaning on, whether they name it or not.
