Cheap Talk
Claims without meaningful cost are weak signals because supporters and pretenders can make them equally easily. Commitment becomes more credible when action puts something valuable at risk.
Two governments can condemn Russia in identical language, yet only one accepts the economic pain of sanctions. The statements sound equally firm; the sacrifice makes them radically different evidence of resolve.
E1The missing price of belief
Cheap talk fails to separate types. Because making a declaration costs almost nothing, both the genuinely committed and the merely performative can produce it. The listener therefore learns little from the claim itself.
A costly act changes that calculation. Money, comfort, opportunity, or political capital is placed at risk, making imitation harder for someone unwilling to bear the consequence. The cost is not incidental waste; it is the filter that turns words into a Costly Signaling test.
E1Where it shows up
Condemnation versus sanctions
A resolution against Russia expresses a position without necessarily changing the speaker's circumstances. Sanctions that impose economic pain reveal more commitment because the condemning side must absorb part of the price.
E1Cost proves commitment, not correctness
Accepting pain can show that an actor is serious, but it does not establish that the actor's judgment is sound or that the chosen action will work. Cheap talk is weak evidence of commitment; costly action is not automatic evidence of truth.
E1Ask what changes if the claim is sincere
When someone makes a forceful promise or declaration, identify one valuable thing they would actually risk if they meant it—money, time, access, comfort, or reputation—then judge the signal by whether that consequence appears, not by the intensity of the words.
