Mièrt hajlamosabbak a jobboldaliak az erőszakra ès a terrorizmusra?

"When compared to individuals associated with a right-wing ideology, individuals adhering to a left-wing ideology had 68% lower odds of engaging in violent (vs. nonviolent) radical behavior (b = −1.15, SE = 0.13, odds ratio [OR] = 0.32, P < 0.001). On the other hand, the difference between individuals motivated by Islamist and right-wing causes was not significant (b = 0.05, SE = 0.14, OR = 1.05, P = 0.747). Expressed in terms of predicted probabilities, the probability of left-wing violent attack was 0.33, that of right-wing violent attack was 0.61, and that of Islamist violent attack was 0.62. These findings remained robust after we controlled for demographic variables (sex, age, education, minority status, immigration status), prior criminal experiences, military experience, and decade in which the perpetrator entered the database. Of the control variables, immigrants were less likely to engage in violence. Those who had a prior violent criminal record were more likely to engage in violence."
