The Curiosity Gap: Why Not Knowing Is an Itch You Have to Scratch

Formalized by economist and psychologist George Loewenstein in 1994, the curiosity gap describes the aversive state of informational deprivation that arises when we become aware of a discrepancy between what we know and what we want to know. This gap creates an unpleasant tension, much like a physical itch, which motivates us to acquire the missing knowledge. Educators and marketers often leverage this principle, creating a sense of mystery or incompleteness to engage audiences and drive them towards learning or purchasing.
