At the heart of this objection lies a conceptual confusion between two very different commodities: whether or not "Peppe" displays mafioso characteristics depends primarily on whether he produces and sells information or guarantees. As I show in the next chapter, if he sells guarantees, he is likely, under certain conditions, to develop mafioso tendencies, whereas if he limits himself to selling information without guaranteeing reliability, he will not. It is crust rather than information that matters.

DEFINE: Distinguishes 'crust' (guaranteeing reliability) from mere information provision as the defining factor in mafioso behavior.
