Fear mongering (or scaremongering or scare tactics) is the use of fear to influence the opinions and actions of others towards some specific end. The feared object or subject is sometimes exaggerated, and the pattern of fear mongering is usually one of repetition, in order to continuously reinforce the intended effects of this tactic, sometimes in the form of a vicious circle.^{[citation needed]}

Probably the best-known example in American politics is the Daisy television commercial, a famous campaign television advertisement beginning with a little girl standing in a meadow with chirping birds, picking the petals of a daisy while counting each petal slowly. When she reaches "9", an ominous-sounding male voice is then heard counting down a missile launch, and as the girl's eyes turn toward something she sees in the sky, the camera zooms in until her pupil fills the screen, blacking it out. When the countdown reaches zero, the blackness is replaced by the flash and mushroom cloud of a nuclear explosion.
