The concept of genre is not limited to classifications and lists. People interact within genres daily. Genre is determined based "on the action it is used to accomplish" by the individuals using that particular genre (Miller 152). The distance between the text or action of genre and its users does not have to be vast. People respond to exigencies provided by genre every day. Exigence is "a set of particular social patterns and expectations that provides a socially objectified motive for addressing" the recurring situation of a particular genre (Miller 158). Seeing genre as a social action provides the "keys to understanding how to participate in the actions of a community (Miller 165). Carolyn Miller argues that, "a rhetorical sound definition of genre must be centered not on the substance or the form of discourse, but on the action it is used to accomplish" (Miller 151).
The idea that rhetorical situations define genre means that participants in genre make decisions based on commonalities and repeat those instances. Genre is not only about the form of but also the mere repetitiveness of similarities. The classroom setting exemplifies this. When students wish to speak, they raise their hands to signify that desire. Raising a hand is the correct response to speaking in turn in that particular social setting. A person at lunch with a group of friends would not raise their hand to speak because the social situation is different. Miller concludes that social actions are the response to "understanding how to participate in the actions of a community" (Miller 156).
Carolyn Miller builds on arguments made by other scholars while also contradicting Bitzer's argument by giving her readers five features to understand genre (Miller 163). She believes that if something is rhetorical, then there will be action. Not only will there be action, but this action will also be repeated. The repetition of action creates a regularized form of discourse. Miller would add that the result has more to do with the action accomplished by the situation. Miller recognizes that a person chooses to take a certain social action within a defined set of rules - rules set in place by that user. Lastly, a situation cannot dictate a response. Miller ends her article with the thought that genres are partly rhetorical education through her statement, "as a recurrent, significant action, a genre embodies an aspect of cultural rationality" (Miller 165),
