The ultimate purpose with Socially Intelligent Agent (SIA) technology is not to simulate social intelligence per se, but to let an agent give an impression of social intelligence. Such user-centred SIA technology, must consider the everyday knowledge and expectations by which users make sense of real, fictive or artificial social beings. This folk-theoretical understanding of other social beings involves several, rather independent levels such as expectations on behaviour, expectations on primitive psychology, models of folk-psychology, understanding of traits, social roles and empathy. The framework presented here allows us to analyse and reconstruct users´ understanding of existing and future SIAs, as well as specifying the levels SIA technology models in order to achieve an impression of social intelligence.
