Identifiable Victim Effect
The tendency of individuals to offer greater aid when a specific, identifiable person is observed under hardship, as compared to a large, vaguely defined group with the same need. Often summarized as concrete images and representations being more powerful sources of persuasion than abstract statistics.

Origin
First described by economist Thomas Schelling in his 1968 essay 'The Life You Save May Be Your Own,' published by the Brookings Institution. Schelling observed that a single identified life elicits far more emotional urgency than a statistical life. The quote 'A single death is a tragedy; a million deaths is a statistic' — often attributed to Stalin — captures the intuition, though its provenance is uncertain.
