Yale professor Wai Chee Dimock lectures on four F. Scott Fitzgerald short stories: "The Rich Boy," "Babylon Revisited," "The Diamond as Big as the Ritz," and "Bernice Bobs Her Hair." She reads each story through the lens of the social type, the generic identity a protagonist either conforms to or deviates from, and argues that this tension drives the dramatic action. Dimock traces Yale itself as a social marker in "The Rich Boy," contrasts the large scale drama of "Diamond" with the smaller scale reversion to type in "Bernice Bobs Her Hair," and situates all four stories within a broader sociology of literary types. Delivered as part of her Yale course Hemingway, Fitzgerald, Faulkner, recorded in Fall 2011, the lecture moves chapter by chapter through close readings, building toward a general claim about how Fitzgerald used social categories as a narrative engine.
