For two weeks in 1956, residents of Taipei, Taiwan, lived in fear of a crazed villain who was allegedly prowling the streets and slashing people at random with a razor or similar weapon. The panic, fueled by rumors and media reports, led to widespread anxiety and vigilante activity, though no credible evidence of the attacker ever emerged. The phantom slasher scare is a classic example of mass delusion and the power of rumor in creating a collective threat.

The phantom slasher panic of Taipei demonstrates how urban legends and mass delusions can take hold in rapidly changing societies, a theme explored by poets and writers interested in the psychology of fear and the construction of social reality. The event has been cited in sociological and psychological studies of mass hysteria, and it resonates with literary works that examine the fragility of order and the ease with which communities can be gripped by irrational terror.
