Little is known about the influence of such attributions on rumour propagation, or how they are maintained when the rumour is transmitted. In four studies (N = 1824) participants exposed to a rumour and asked to transmit it overwhelmingly attributed it either to a credible friend of a friend, or to a generic friend (e.g. \u2018a friend told me about a serial killer in town\u2019). In both cases, participants engaged in source shortening: e.g. when told by a friend that \u2018a friend told me \u2026\u2019 they shared the rumour as coming from \u2018a friend\u2019 instead of \u2018a friend of friend\u2019. Source shortening and reliance on credible sources boosted rumour propagation by increasing the rumours\u2019 perceived plausibility and participants\u2019 willingness to share them. Models show that, in linear transmission chains, the generic friend attribution dominates, but that allowing each individual to be exposed to the rumour from several sources enables the maintenance of the credible friend of a friend attribution.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Altay, S., Claidi\u00e8re, N., &amp; Mercier, H.
