    🚨 New preprint with @hugoreasoning & Nicolas Claidière on rumor diffusion 🚨 We explain why so many rumors (like the ones below) are attributed to a credible friend of a friend. Pre-print: https://psyarxiv.com/5czka  1/5pic.twitter.com/dxPuzYBoyU

        Key findings: (i) Attribution to a credible friend of a friend increased a rumor’s perceived plausibility, and participants’ willingness to share it. 2/5

        (ii) Credible friend of a friend attributions remained stable across multiple transmissions, instead of the number of friends mentioned increasing with each transmission, i.e. participants systematically shortened the sources when sharing the rumors. 3/5

        (iii) Rumors attributed to a single (not credible) friend dominated linear transmission chains. But ecological transmission chains taking into account redundancy allowed the credible friend of a friend to persist or dominate—as it seems to be the case in the wild. 4/5

        (iv) This preference for attributing rumors to a credible friend of a friend may reflect reputation management considerations. Notably by allowing senders to score social points while minimizing their epistemic responsibility in case the rumor turns out to be false. 5/5
