     “It’s the Lake Wobegon effect,” said Dr. Daniel P. Sulmasy, senior author and a professor of medicine and ethics at the University of Chicago. “If you have more than 50 percent of patients saying their chances are better than average of avoiding some harm or obtaining some benefit, they are being unrealistically optimistic because you can’t say that most people are above average.”
