About the Book: In The Parasitic Mind, Dr. Gad Saad—renowned psychologist and host of The Saad Truth—exposes the rise of political correctness and the “idea pathogens” that threaten free speech, reason, and intellectual freedom. Drawing on logic and science, he reveals how these destructive ideologies spread through academia and culture, eroding truth and common sense. This bold and provocative nonfiction manifesto is a call to defend critical thinking and preserve the core values of Western liberalism.
