How do you define "effective?"

The most common American form of lobotomy involved sticking what was, in essence, an ice pick behind the eye and scrambling the brains around. Most often this affected the person's behavior/demeanor. It did often make people more docile, but not always. Howard Dulley, for example, wrote in "My Lobotomy" about how his behavior became worse after his; it can be debated whether this was a result of his lobotomy or not.

As far as electro-shock therapy, it is actually still used to this day. However it is used in more controlled doses than it was in the days of "One Flew Over the Cuckoo's Nest" (the author Ken Kesey, was notably able to bribe an orderly to give him a round of treatment so he could accurately describe it in his book). These days it is most often used to treat severe depression that isn't affected by more common antidepressants.

By effective, I mean achieving the desired results. By making the patient more docile or compliant.
