Religious fundamentalism has been shown to be associated with higher levels of prejudice, ethnocentrism, and militarism, in spite of the compassionate values promoted by the religious faiths that most fundamentalists believe in. Based on terror management theory, we hypothesized that priming these compassionate values would encourage a shift toward less support for violent solutions to the current Middle Eastern conflict, especially when they are combined with reminders of one’s mortality. Study 1 demonstrated that among Americans, religious fundamentalism was associated with greater support for extreme military interventions, except when participants were reminded of their mortality and primed with compassionate religious values. The combination of mortality salience and compassionate religious values led to significant decreases in support for such interventions among high but not low fundamentalists. Study 2 replicated this finding and showed that it depends on the association of the compassionate values with an authoritative religious source; presentation of these values in a secular context had no effect on fundamentalists. Study 3 replicated these effects in a sample of Iranian Shiite Muslims: although a reminder of death increased anti-Western attitudes among participants primed with secular compassionate values, it decreased anti-Western attitudes among those primed with compassionate values from the Koran.
