"This is an extraordinary piece of work that should be read by every mental health professional, minimally. The book might also serve well as a supplemental advanced undergraduate or graduate textbook in a psychopathology or even a research methods class. Where research methods courses separate good from bad science, Whitaker and Cosgrove have now provided us with numerous examples of bad science to which we can now add, corrupt science." (Fred Ernst, Journal of Contemporary Psychotherapy, Vol. 46, 2016)
