What is the author's perspective in the nonfiction book, Whistling Vivaldi?

Whistling Vivaldi: How Stereotypes Affect Us and What We Can Do is written alternatingly in the first, second and third person. Author Claude Steele addresses the reader using the second person, tells them about his life and the work he’s done with his colleagues in the first person, and tells them stories other people in the third person. Overall, this creates more of a conversational tone than if Steele had stuck to a single perspective, because it is more like the natural flow of human speech, rather than a narrative. This is especially interesting coming from Steele, because it is so different to the academic style in which he is used to writing, and makes his work a lot more accessible to a wider audience. It also allows him to combine references to a lot of different studies, both by himself and by others, rather than just focusing on one at a time.
