The Decade of Behavior is the American Psychological Association's nickname for the 2000s. The name represents a public education campaign to bring attention to the importance of behavioral and social research.[1] The initiative has been endorsed by more than 70 professional associations across a variety of disciplines.[2] The campaign was first championed in 1998 by Richard C. McCarty, then-Executive Director of Science of the APA.
It is the successor to the 1990s' "Decade of the Brain".
