Social selection maintains reliable communication. Social costs (aggressive bouts, filled squares; latency to attack, empty squares) on out‐of‐equilibrium and control signals. Unreliable signaling of strength (darkened stripe) and weakness (paled stripe) is punished by increased and faster costs relative to reliable signaling (control). Mean ± SEM are shown. Symbols illustrate significant differences in pairwise post‐hoc tests between treatments (^*** P < 0.001, ^** P < 0.01, • P < 0.1, ◯ P > 0.1).
