   What’s more, such a theory can be arrived at by employing the method of conceptual analysis, undertaken from the proverbial armchair. The idea is that the theorist starts with a putative set of criteria for the correct application of the target concept, and then she tests this account against her intuitions about that concept. If the account entails that the concept applies to particular cases that it intuitively does not apply to, then this provides reason to reject or revise the account in question. By contrast, if the account entails that the target concept applies to certain cases and this is the intuitively correct result, this tends to provide affirmative support for the account. The account successfully captures the target concept to the extent that it yields intuitively correct results about particular cases, and does so in an explanatorily satisfying way (as opposed to an ad hoc manner). (For a more in depth discussion of the methodology of conceptual analysis as applied to the concept of law, see Shapiro 2011, 16–22.)
