Costly signals being more powerful

Any company can write “confident”. A generous warranty makes confidence expensive. One is typography; the other can become a refund.

Costly signals work because weaker senders struggle to copy them. Publishing prices removes the freedom to improvise numbers privately. A maintained project proves more initiative than a CV adjective. Repairability costs real design effort when durability is the promise. A service promising rapid response sounds bolder when the response clock and missed-target credit are both public.

Expense alone proves very little. Bonfires are costly too.

A lavish launch may demonstrate only access to a lavish-launch budget. An enormous office can signal resources while the product remains gloriously mediocre. Luxury packaging can prove that cardboard was available. The audience needs a reason the cost would be foolish for an inferior offer to bear.

The cost must connect to the claimed quality. What commitment becomes painful if the promise is false? Refund the fee when the outcome is missed. Publish response times. Let candidates meet the team they will actually join. Put future revenue, reputation or operational effort behind the claim. The strongest signal often looks operationally boring because it lives in the system, not the launch party.

Advertising asks customers to believe. A costly signal shows what the company is prepared to lose if belief turns out misplaced. The question for any grand claim is brutally simple: what has the claimant made harder for themselves? Without that stake, the peacock tail is clip-on.
