Abstract

Deceptive signals are a challenge to explain because on average, signals should be reliable. When being deceived is costly to the receiver, a coevolutionary struggle between senders and receivers can ensue. Recent work by MacĂ­as Garcia and Ramirez raises the intriguing possibility that through such a coevolutionary process, cheats can become honest.
