Skinner attributes creativity to ‘behavioral mutations’, unusual acts emitted accidentally but selected by the environment for reinforcement. The author suggests that Skinner’s account can adequately encompass many creative phenomena, notably some recent, influential artistic approaches and the sex differences in productivity. However, the account also shows serious weaknesses. In particular, it implies that all individuals, including subhumans, are equally capable of creative behavior, and that an individual’s creative acts, and his or her evaluation of them, must reflect the environment’s standards. Moreover, Skinner has ignored important complications of creativity’s definition and practice.
