Answer:The superpredator myth, known by its proponents as the superpredator theory, was a theory in criminology that became popular the 1990s in the United States, positing that a small but significant and increasing population of impulsive (often urban) youth were willing to commit violent crimes without remorse. John J. DiIulio Jr., the criminologist and political scientist who came up with the idea, redicted a large increase in youth crime and violence due to superpredators.
