Although all archaeologists subscribe in principle to building strong cases in support of their inferences, behavioural archaeology alone has created methodology for developing strong cases in practice. The behavioural version of the strong case approach rests on two main pillars: (1) nomothetic (generalising) strategies, consisting of research in experimental archaeology, ethnoarchaeology, and long-term processes of behavioural change to produce principles necessary for inference; and (2) the formation processes of supporting evidence when constructing inferences.
