Is There a Difference Between Sane and Insane?

Rosenhan also at some point previous to this underwent a experimental eight day inpatient. And he wanted to see if psychiatrists could do the most basic part of their job, which is identify the difference between a sane person and an insane person. So Rossine Hain decided that he was going to design an experiment using those two experiences. It really did make me wonder if he was influenced at all by one Fleur over the Cuckoo's Nest. I don't know.
