Step-by-step explanation:
Andrew J. Rotherham likely disclosed his membership in an educational group at the end of his article to maintain transparency and establish credibility with his readers. By sharing his affiliation, Rotherham lets readers know that he has a particular interest and possibly expertise in the subject matter, which can strengthen his arguments by showing that they are informed by direct experience and knowledge. However, this disclosure might also impact the reader's perception of the argument, as it could introduce the question of bias. Knowing Rotherham's affiliations helps readers to critically assess the content and the potential influence his perspective may have on the presented argument.
The act of disclosing such information is important in the process of ethical journalism and scholarship, as it shows respect for the audience's right to critically evaluate the context in which information is presented. Deciding whether the membership enhances or detracts from the argument might depend on one's own opinions about the group itself or the issue at hand. Ultimately, such a disclosure invites more informed and nuanced understanding of the argument, balancing the author's perspective with the readers' ability to evaluate its validity independently.
