Honest actors must spend resources to distinguish themselves from dishonest mimics

Evidence

The first, and to my mind most serious, weakness of this model is that there is nothing which enables the honest salesman to distinguish himself from the dishonest one. Everything the former can do the latter can do as well. The dishonest type is the cancerous cell which ‘acts’ like the healthy one. It is here that the role of commitments can assume importance. If the stake is high enough the honest salesman will search for ways of persuading customers that he really is honest; he will be willing to spend resources to distinguish himself from his possible counterpart. This is not included in the foregoing model of reputation acquisition. — Diego Gambetta, Trust - Making and Breaking Cooperative…, 1006

• XREF: The ‘cancerous cell that acts like the healthy one’ directly parallels Saramago’s theme of how, with blindness, dishonest actors can mimic trustworthy behavior; also connects to signaling-cost theory.
• DEEPTHINKING: The impossibility of the honest type distinguishing itself from the dishonest mimic, absent costly commitment, is the deep problem that observability alone cannot solve — cuts to the heart of why trust needs more than monitoring.
