El sociópata de la puerta de al lado

The idea that such individuals are often undetected is unsettling. I'm curious what motivated Martha Stout to explore this topic in such depth.

Some cases felt chilling and made me question how many sociopaths might be in my own community. Would love to hear if others felt the same.

The book lists some behaviors to watch for, but I wonder how reliable these are outside of a clinical setting. Has anyone used these in real situations?
