                             the human perception of intelligence. The comparison of computers’ sociality
                             to the human one is sharp - one can see that humans are able to get involved in
                             very complex behaviours when interacting, even when they have only a minimal
                             amount of conscious data about the others.
                               If the final aim is to engender some social intelligence in artificial agents, the
                             usual approaches (e.g. trying to limit misunderstandings in the interpretation of
                             messages exchanged or by reducing uncertainty in social organisation) might
                             not be the best way forward. These approaches do not contradict that aim, in
                             fact they can be useful, but they will not be sufficient.

                             2.     Socially Intelligence In MAS

                               The problem of organising interactions among computers has grown dras-
                             tically since the spread of PCs to a wider public, and more precisely with the
                             ever-wider adoption of computer networks. The field of Multi-Agent Systems
                             that has developed in the last years was originally led by the idea of having
                             several artificial intelligences accomplish tasks together. This is often seen as
                             a continuation of both Artificial Intelligence and Distributed Artificial Intelli-
                             gence, and researchers usually look for ways of building societies of artificial
                             intelligences [12].
                               There exists a commonly accepted definition of a MAS: it is constituted of
                             an environment that evolves in time in which autonomous entities (agents) are
                             able to act; they can also interact; the overall organisation is effected by rules
                             that coordinate time evolution and all actions of the entities. Four axes can thus
                             be emphasised for such a systems, (called the AEIO model): the exploration
                             of what an Agent should be (mainly in terms of cognition and perception),
                             what characteristics the Environment has, which kind of Interactions can exist
                             between the entities, and what kind of Organisation is needed to put these
                             different elements together [2].
                               The reasons why people use MAS are diverse. Some need to coordinate
                             computers, as in networks, some need to coherently integrate different expert
                             systems, and some need to make robots act together. In most cases, it is common
                             to consider that the reliability of the system, its predictability and its efficiency
                             are what is most important. In order to coordinate agents so that they work
                             together without interfering with each other it is common to use a set of norms.
                             In that case agents have clear roles that are interdependent and a known set
                             of acquaintances with complementary roles (for example [5]. In this case,
                             communication is mainly used by agents to make requests for help and to
                             accept tasks that are proposed to them. Since tasks are necessarily thought as
                             collective, the social life of agents is very important for the global system. They
                             are thus designedwiththis ability tointeract, either bybeingcommittedtoothers
