Lurking, death nigglesWhile thinking about death directly, Pyszczynski says, folks do rational things to get away from it, like trying to get healthy. It’s when death lurks on the fringes of consciousness that they cling to worldviews and seek self-esteem. "That helps explain why these ideas might seem strange to some people," says Pyszczynski, a professor at the University of Colorado at Colorado Springs. "You can’t really introspect on it. While you’re thinking about death, this isn’t what you do."
