Chapter 1 DECEIVING IN GOLEM : HOWTO

We rst introduce GOLEM, a Multi-Agent world that we designed in order to study:-diierent social attitudes and personalities in interaction and, in particular , attitudes in delegating tasks to other agents (search for help) and in adopting goals of others (help);-reasoning about delegating and adopting tasks and about the other agents' personality. We then shortly illustrate the diierent forms of deception that are allowed in this world. This enables us to provide some basic ontology of deception and to clarify the relationships between deception and lie, deception and mistake and so on. In the main part of the paper, we focus on a family of examples of deception, which are particularly relevant in GOLEM: social and intentional deceptions, about the agent itself (its personality, its capabilities, its goals) rather than about the domain, and in order to obtain help (instrumental deception), which is, at present, the most important social motive for GOLEM agents. All these forms of deception are not necessarily based on implicit or explicit communication: that is, they do not necessarily imply lie.
