One thing I found truly compelling from the textbook was from Chapter 2, when prefrontal lobotomies were discussed. A lobotomy was long considered the solution for many severe mental disorders. Before this class, I had been exposed to lobotomies (or at least their effects) through television and movies. In both the movie 'One Flew Over the Cuckoo's Nest' and in an episode of 'The Simpsons', the patients that had a lobotomy performed on them appeared extremely incapacitated, almost as though entire brain had been removed. After actually reading the effects of a lobotomy, I discovered that it had been a tragic case of confirmation bias for far too long.
Lobotomies nearly always ended in the patient being rendered in a catatonic state, not curing the mental illness so much as disabling the brain as a whole. But since researchers could prove that the mental illness was no longer visible in the patients behavior, they credited themselves. The developer of the prefrontal lobotomy was even awarded a Nobel Prize! I can only wonder if the victims of lobotomies and their families ever pursued lawful action against those doctors that administered them, since it created more problems than it helped. Lobotomies have long been portrayed as a slight form of torture or punishment in mass media.
