In the early 1970s, Stanford professor Dr. Rosenhan conducted an experiment that sent sane patients into psychiatric wards. The result of this experiment was a damning paper about psychiatric practices, which had a profound impact on the field of psychiatry. It led to the closure of institutions and the changing of mental health diagnosis forever. However, what if this experiment was itself deeply flawed? That is the question that Susannah Cahalan explores in her thoroughly engrossing investigation into this staggering case, where nothing is quite as it seems. Cahalan delves into the background of Dr. Rosenhan and his experiment, revealing the motivations behind it and the potential biases that may have affected the results. She also examines the impact of the experiment on the patients involved, as well as on the mental health profession as a whole. Through her meticulous research and compelling storytelling, Cahalan sheds light on the complexities of mental illness and challenges our understanding of it. This is a must-read for anyone interested in the field of psychology, mental health, and the power of scientific research.
