A general theory is testable not directly but through consequences it implies when it is taken together with auxiliary hypotheses. The test can be weaker or stronger depending, in particular, on the extent to which the consequences tested are specifically entailed by the theory (as opposed to being mostly entailed by the auxiliary hypotheses and being equally compatible with other general theories). The earliest experimental work based on Relevance Theory (Jorgensen, Miller and Sperber, 1984; Happé 1993) tested and confirmed Sperber and Wilson’s (1981) echoic account of irony (and much experimental work done since on irony has broadly confirmed it and refined it further). While this account of irony is part and parcel of Relevance Theory, it is nevertheless compatible with different pragmatic approaches. The experimental confirmation of this account, therefore, provides only weak support for Relevance Theory as a whole. More recent experimental work has made explicit, tested and confirmed other and more specific and central consequences of Relevance Theory (e.g. Sperber, Cara and Girotto, 1995; Politzer, 1996; Gibbs and Moise, 1997; Hardman, 1998; Nicolle and Clark, 1999; Matsui, 2000, 2001; Girotto, Kemmelmeir, Sperber and Van der Henst, 2001; Noveck, 2001; Noveck, Bianco and Castry, 2001; Van der Henst, Sperber and Politzer, 2002, Van der Henst, Carles and Sperber, 2002, Noveck and Posada, 2003; Ryder and Leinonen, 2003).
