The Bathtub Test
Dr. Stephen Smith, an American psychiatrist was visiting attending a conference in Israel and decided to visit one of the local hospitals specializing in mental health. On his visit, Dr. Smith asked the hospital director, Dr. Dudu Smadar how he determined whether or not a patient should be institutionalized.
"Well," said Dr. Smadar, "we fill up a bathtub, then we offer a teaspoon, a teacup and a bucket to the patient and ask him or her to empty the bathtub."
"Oh, I understand," said Dr. Smith. "A normal person would use the bucket because it's bigger than the spoon or the teacup."
"No," said Dr. Smadar, "a normal person would pull the plug. Dr. Smith, do you want a bed near the window?"
