What kind of research methodology does Schlosser employ in his book?

In his book, Schlosser employs investigative journalism, which is characterized by a detailed and immersive approach that includes interviews, firsthand accounts, and comprehensive analysis. This methodology allows him to explore the fast-food industry from various angles, including its economic, social, and health impacts, as well as the experiences of those involved in the industry, such as workers and consumers. Through direct engagement with sources and a commitment to uncovering hidden truths, Schlosser provides a rich narrative that combines storytelling with factual exploration, helping readers understand the complexities of fast food in America.

This investigative approach is critical because it not only presents data and statistics but also weaves in personal stories and broader industry trends, contributing to a more nuanced understanding of the subject matter. Other methodologies listed, such as experimental research or survey research, do not capture the depth and breadth of Schlosser’s examination of the fast-food phenomenon, which is rooted in a thorough investigation of real-life experiences and implications. Additionally, relying solely on secondary research would not afford the same depth of insight and original findings that Schlosser's investigative journalism delivers.
