Psychologie positiveLa psychologie positive est une discipline de la psychologie fondée officiellement en 1998 lors du congrès annuel de l'Association américaine de psychologie par son président de l'époque, Martin E. P. Seligman ( son discours publié en 1999 dans le journal de l'APA, The American Psychologist). Cependant, la psychologie positive a des racines plus anciennes. La psychologie positive ne doit pas être confondue avec la pensée positive, une pseudo-science basée sur l'autosuggestion, faisant l'objet de nombreux best-sellers vendus à des millions d'exemplaires à travers le monde depuis les années 1950.
