I started reading a new book today. A little light reading called The Sociopath Next Door by Martha Stout. I saw it a couple weeks ago while browsing at Barnes & Noble and put it on hold at the library. According to the book, 4% of the U.S. population are sociopaths, or 1 out of 25 people. That number seemed alarming until I started to read the book, which points out that this doesn’t mean that 1 out of 25 people are violent or serial killers. There are more ways to qualify as sociopathic. The one common element is a lack of conscience.
