StatusActive — read 2026-10-29 (NOTE-1396) in full, from the authors' accepted manuscript on SocArXiv; worth reading as the field experiment that removes the exchange of narratives from an otherwise identical canvass and finds the effect goes with it, and as two replications on transphobia, one with a stranger's video narrative and one by phone. Read it knowing that the effects are small (pooled d = 0.08 and 0.04) and self-reported, that the argument-only arm is in Experiment 1 alone and was half as long as the full conversation, that "durable" is a pooled effect over waves ending at about 4.5 months whose last wave alone is not significant for prejudice, and that the mechanism is not tested.

Why this is here

The exchange cited it for the claim that a non-judgmental exchange of narratives reduced exclusionary attitudes durably, where arguments alone did not. The abstract agrees, with qualifications the exchange left out: “durably” means at least four months; the arguments-only comparison is from Experiment 1 alone; and the effects are small (d = 0.08 and 0.04). For CLAIM-275, the narrative exchange is an invitation to take another’s perspective that comes before any change of view, as the favour does.
