The New York Times asserted that "Mae, then, is not a victim but a dull villain." In my opinion, this statement slightly oversimplifies the issue. I would restate their analysis to say: over the course of the novel, Mae becomes increasingly convinced that immoral actions against privacy are actually moral. To the world and to the readers, she is a villain; but in her own mind, she is a hero. Today, I will explain the factors that led Mae to believe so strongly in her immoral actions.
Mae espouses the role that the company expects her to be: an activist against privacy. In the Stanford Experiment, there were several factors that allowed for such a dark outcome For one, the participants were isolated from anyone not participating in the experiment. Mae lives her entire life within the confines of The Circle, and only surrounds herself with Circle employees. By isolating herself from those who don't share The Circle's values, she never hears opposition to those values. This further ingrains those ideas into her mind as justifiable and right.
Additionally, the participants at Stanford knew that their experiment was being run by the prestigious scientist Phillip Zimbardo; thus, they have little reason to believe that anything they do could be immoral. In Mae's case, she is constantly reassured by the Circle higher-ups that her attitude against privacy is morally correct. This reassurance from people stronger, more influential, and wealthier than Mae completely eliminates any doubt from Mae's head that her anti-privacy attitude has any negative bearing.
Overall, just like the Stanford Prison Experiment, Mae is a perfect example of what can go wrong in a "cult-like" situation. It is my strong suspicion that Dave Eggers is trying to point out where he sees our society might be headed. An increasingly globalized world will have increasingly similar ideas, which could effectively lead to a large-scale, real-world example of The Circle. This example reminds us of the importance of bipartisanship, and how uni-partisanship can lead to extreme ideas and a lack of moral evaluation.
