Consider the following methodology, which can be considered an argument field. Conversation analysis is a well-defined method and school of thought that analyses language from a social perspective. It seeks to study naturally occurring talk, either in everyday conversations or institutional settings such as schools and organizations. Any conversation analysis must be strictly based on the actual conversation, and outside categories (such as the race or class of the speaker) cannot be imposed unless they are referred to in the conversation being analyzed. Conversation analysts seek to find out what actions are performed by speakers in conversation (e.g. telling stories, making arrangements), and how they organize their talk in order to do that. They use a special mode of analysis to understand how actions are performed in talk called the next turn proof procedure. In this procedure, the action of the speaker is understood by examining how the following speaker understood them. When discussing the organization of talk, conversation analysts use terms such as turns, sequence organization and repair (how speakers fix errors in their talk).
