Absolutists who violently rejected offers of money or peace for sacred land were considerably more inclined to accept deals that involved their enemies making symbolic but difficult gestures. For example, Palestinian hard-liners were more willing to consider recognizing the right of Israel to exist if the Israelis simply offered an official apology for Palestinian suffering in the 1948 war. Similarly, Israeli respondents said they could live with a partition of Jerusalem and borders very close to those that existed before the 1967 war if Hamas and the other major Palestinian groups explicitly recognized Israel’s right to exist.
Remarkably, our survey results were mirrored by our discussions with political leaders from both sides.
Across the world, people believe that devotion to sacred or core values that incorporate moral beliefs — like the welfare of family and country, or commitment to religion and honor — are, or ought to be, absolute and inviolable. Our studies, carried out with the support of the National Science Foundation and the Defense Department, suggest that people will reject material compensation for dropping their commitment to sacred values and will defend those values regardless of the costs.
