SUMMARY:Dynamics\, robustness and fragility of trust - Dusko Pavlovic

DESCRIPTION:I present a model of the process of trust building that sugges
 ts that trust is like money: the rich get richer. The proviso is that the 
 cheaters do not wait for too long\, on the average\, with their deceit. Th
 e model explains the results of some recent empiric studies\, pointing to 
 a remarkable phenomenon of *adverse selection*: a greater percentage of un
 reliable or malicious web merchants are found among those with certain (mo
 st popular) types of trust certificates\, then among those without. While 
 some such findings can be attributed to a lack of diligence\, and even to 
 conflicts of interest in trust authorities\, the model suggests that the p
 ublic trust networks would remain attractive targets for spoofing even if 
 trust authorities were perfectly diligent. If the time permits\, I shall d
 iscuss some old and some new ways to decrease this vulnerability\, and som
 e problems for exploration.\n\n
