 In the academic study of religions, discussions of monothetic and polythetic approaches have primarily been in service of developing a definition of the  term.[13]  How can alternate definitions of religion be assessed? If one were to offer a lexical definition (that is, a description of what the term means in common usage, as with a dictionary definition), then the definition one offers could be shown to be wrong. In common usage, for example, Buddhism typically is considered a religion and capitalism typically is not. On this point, some believe erroneously that one can correct a definition by pointing to some fact about the referents of the term. One sees this assumption, for example, in those who argue that the western discovery of Buddhism shows that theistic definitions of religion are wrong (e.g., Southwold 1978: 367). One can correct a real or lexical definition in this way, but not a stipulative definition, that is, a description of the meaning that one assigns to the term. When one offers a stipulative definition, that definition cannot be wrong. Stipulative definitions are assessed not by whether they are true or false but rather by their usefulness, and that assessment will be purpose-relative (cf. Berger 1967: 175). De Muckadell (2014) rejects stipulative definitions of religion for this reason, arguing that one cannot critique them and that they force scholars simply to “accept whatever definition is offered”. She gives the example of a problematic stipulative definition of religion as “ice-skating while singing” which, she argues, can only be rejected by using a real definition of religion that shows the ice-skating definition to be false. However, even without knowing the real essence of religion, one can critique a stipulative definition, either for being less adequate or appropriate for a particular purpose (such as studying forms of life across cultures) or, as with the ice-skating example, for being so far from a lexical definition that it is adequate or appropriate for almost no purpose.
