Do other animals have a "theory of mind"?

SmartBrief on Leadership | Aug 01, 2016

Two psychologists examining the question of the "theory of mind" -- whether animals understand that others have internal mental states, too -- say that monkeys and apes can't imagine the world being different from the way it is.
