Embedded Deception: Interpersonal Trust, Cooperative Expectations, and the Sharing of Fabricated Intelligence

Abstract

When and why do friendly states deliberately share and unwittingly accept fabricated intelligence about others? Recent work on the interpersonal foundations of security cooperation suggests intelligence liaison is a type of embedded relationship that requires a dependable route for exchange (close personal ties) and a consistent record of exchange (reliably meeting expectations). We extend this argument to show that the relational embeddedness underpinning truthful intelligence liaison also explains the sharing of fabricated intelligence. We argue that intimate personal relations and a history of reliable exchange create a channel for effectively transmitting false information, for the recipient is unlikely to challenge its authenticity, and that violated cooperative expectations provide a reason for attempting to deceive a partner. Drawing on extensive archival research, we evaluate our theory by analyzing Britain's decision to share fabricated intelligence about Germany with the United States in 1941.
