Map shared values before mapping the disagreement

In any conflict, identify the values or goals you and the other person genuinely share before cataloguing differences.

Why it works

Naive realism polarizes: I see reality; they don’t. Identifying shared values de-polarizes by demonstrating that the conflict is over means or emphasis, not over fundamental humanity. It also reduces motivated reasoning, because people are more willing to update beliefs when they don’t feel their entire value system is under attack.

How to do it

1. Before any difficult conversation, list two or three things both parties genuinely care about.
2. Open the conversation by naming the shared goal explicitly: "We both want X — I think we disagree about how to get there."
3. Return to the shared goal if the conversation escalates.

Evidence

Common-ground framing is consistent with research on identity-protective cognition — people are more open to disconfirming evidence when their identity is affirmed first. The specific approach is practitioner-led; the underlying mechanism is supported by self-affirmation research. Sherif et al.’s (1961) Robbers Cave field study showed that introducing superordinate goals both groups genuinely shared reduced entrenched intergroup hostility, direct field evidence that surfacing shared aims de-polarizes conflict.

Common mistake

Stating shared values as a tactical opener the other person can see through ("I know we both want X, but…") — it must be genuine to work.
