Resumen

Este estudio examina la motivación de los 197 tiroteos masivos habidos en el periodo de 1966 a 2023 a partir del análisis de cuatro variables extraídas de The Violence Project: psicosis, problemas laborales, misoginia y búsqueda de fama. Los resultados mostraron que un 48,2 % de los casos se encuentran motivados por una o más de las variables seleccionadas. La psicosis fue la motivación más prevalente, aunque está presente en menos de un tercio de los casos. El segundo motivo más frecuente fueron los problemas laborales. La búsqueda de fama fue el tercer factor motivacional en cuanto a prevalencia y el único que ha experimentado un aumento significativo en la última década analizada. Ello podría estar asociado a la mayor visibilidad de estos sucesos luctuosos, debido al auge de Internet. La misoginia está presente en un 4,1 % de los casos. Por lo general se encuentran evidencias del predominio de un único motivo en los tiroteos masivos incluidos en el estudio. Sin embargo, el análisis de factores personales y ambientales, tanto del presente como de la historia de los perpetradores, sugiere la conveniencia de profundizar en estos hechos y alejarse de análisis simplistas a la hora de indagar sobre las razones que llevan a estos asesinos a cometer estas masacres.
