This is a difficult book to read, just because of the horrifying subject matter. But it is an important part of 20th century American history that needs to be examined, and Reverby's take is extremely strong. She aims to complicate a narrative saying that Southern racism was the only major factor behind the "study." Racism was clearly the canvas on which it was all painted, but there was also quite a bit about medical arrogance, knowledge, paradigms, government agency imperatives, etc. Her main point was that the *real* crime, in the context of the day, was the systematic deception of the study's (exclusively black) participants. They were deprived of agency. Whether or not the intentions of the study's leaders were benign or malicious, then, would be besides the point.
The clinical writing in the studies and notes reminded me of Nazi Germany's sanitized documents about the Holocaust.
