IMRaD format is different from an argument paper format for many reasons. First, The audience is usually different and with IMRaD, the writer is not trying to persuade anyone, but rather inform then on the new data they collected. Therefore, IMRaD is usually new evidence, while argument papers are developed from older, multiple papers or articles. Sometimes, both of these types of papers have subheadings to help organize there paper. Although they can both have subheadings, IMRaD is used to skim the paper and find the information when the question arises, while persuasive papers want you to get all the information at once. Another difference is that the IMRaD paper has an abstract to give critical background information. While persuasive papers can have abstracts, IMRaD abstracts are more important and necessary for the reader, because we usually argue topics that are well-known so people do not just agree with you, but IMRaD can be totally new information to every reader.
