We report a series of experiments carried out with Palestinian and Israeli participants showing that violent opposition to compromise over issues considered sacred is increased by offering material incentives to compromise but decreased when the adversary makes symbolic compromises over their own sacred values. These results demonstrate some of the unique properties of reasoning and decision-making over sacred values. We show that the use of material incentives to promote the peaceful resolution of political and cultural conflicts may backfire when adversaries (...) treat contested issues as sacred values.

Violent extremism is often explicitly motivated by commitment to abstract ideals such as the nation or divine law – so-called “sacred” values that are relatively insensitive to material incentives and define our primary reference groups. Moreover, extreme pro-group behavior seems to intensify after social exclusion. This fMRI study explores underlying neural and behavioral relationships between sacred values, violent extremism, and social exclusion. Ethnographic fieldwork and psychological surveys were carried out among young men from a European Muslim community in neighborhoods in (...) and around Barcelona, Spain. Candidates for an fMRI experiment were selected from those who expressed willingness to engage in or facilitate, violence associated with jihadist causes. In the scanner, participants were assessed for their willingness to fight and die for in-group sacred values before and after an experimental manipulation using Cyberball, a toss ball game known to yield strong feelings of social exclusion. Results indicate that neural activity associated with sacred value processing in a sample vulnerable to recruitment into violent extremism shows marked activity in the left inferior frontal gyrus, a region previously associated with sacred values and rule retrieval. Participants also behaviorally expressed greater willingness to fight and die for sacred versus non-sacred values, consistent with previous studies of combatants and noncombatants. The social exclusion manipulation specifically affected non-sacred values, increasing their similarities with sacred values in terms of heightened left inferior frontal activity and greater expressed willingness to fight and die. These findings suggest that sacralization of values interacts with willingness to engage in extreme behavior in populations vulnerable to radicalization. In addition, social exclusion may be a relevant factor motivating violent extremism and consolidation of sacred values. If so, counteracting social exclusion and sacralization of values should figure into policies to prevent radicalization. (shrink)

In standard models of decision making, participation in violent political action is understood as the product of instrumentally rational reasoning. According to this line of thinking, instrumentally rational individuals will participate in violent political action only if there are selective incentives that are limited to participants. We argue in favor of an alternate model of political violence where participants are motivated by moral commitments to collective sacred values. Correlative and experimental empirical evidence in the context of the Israeli–Palestinian conflict strongly (...) supports this alternate view. (shrink)

AS diplomats stitch together a cease-fire between Hamas and Israel, the most depressing feature of the conflict is the sense that future fighting is inevitable. Rational calculation suggests that neither side can win these wars. The thousands of lives and billions of dollars sacrificed in fighting demonstrate the advantages of peace and coexistence; yet still both sides opt to fight. This small territory is the world's great symbolic knot. “Palestine is the mother of all problems” is a common refrain among (...) people we have interviewed across the Muslim world: from Middle Eastern leaders to fighters in the remote island jungles of Indonesia; from Islamist senators in Pakistan to volunteers for martyrdom on the move from Morocco to Iraq. Some analysts see this as a testament to the essentially religious nature of the conflict. But research we recently undertook suggests a way to go beyond that. For there is a moral logic to seemingly intractable religious and cultural disputes. These conflicts cannot be reduced to secular calculations of interest but must be dealt with on their own terms, a logic very different from the marketplace or realpolitik. (shrink)

Sacred values are different from secular values in that they are often associated with violations of the cost-benefit logic of rational choice models. Previous work on sacred values has been largely limited to religious or territorial conflicts deeply embedded in historical contexts. In this work we find that the Iranian nuclear program, a relatively recent development, is treated as sacred by some Iranians, leading to a greater disapproval of deals which involve monetary incentives to end the program. Our results suggest (...) that depending on the prevalence of such values, incentive-focused negotiations may backfire. (shrink)

We investigated the influence of humiliation on inter-group conflict in three studies of Palestinians living in the West Bank and Gaza. We demonstrate that experienced humiliation produces an inertia effect; a tendency towards inaction that suppresses rebellious or violent action but which paradoxically also suppresses support for acts of inter-group compromise. In Study 1, Palestinians who felt more humiliated by the Israeli occupation were less likely to support suicide attacks against Israelis. In Study 2, priming Palestinians with a humiliating experience (...) caused fewer expressions of joy when subsequently hearing about suicide attacks. In Study 3, Palestinians who felt more humiliated by peace deals were less likely to support those deals, while Israeli symbolic compromises that decreased feelings of humiliation increased support for the same deals. While the experience of humiliation does not seem to contribute to political violence, it does seem to suppress support for conflict resolution. (shrink)

Pepper & Nettle argue that the more present-oriented behavior associated with a low socioeconomic status is an adaptive response to having relatively little control over the future. However, a study of fasters during Ramadan shows that self-imposed deprivation, which carries no implications regarding the ability to realize deferred rewards, is associated with loss and risk aversion.
