Which component is NOT typically included in an introduction?

In a typical introduction, the primary goal is to set the stage for the discussion that follows. This includes providing background information about the topic to give context to the reader, stating the thesis which encapsulates the main argument or point of the piece, and sometimes offering an outline of main points that will be discussed.

Including a detailed conclusion of the argument is not a standard practice for an introduction because the introduction is meant to present information about what will be discussed rather than summarize what has been concluded. The conclusion serves a different purpose, which is to wrap up and reflect on the arguments made throughout the piece. Thus, not having a detailed conclusion in the introduction is consistent with its role in the structure of writing.
