This article responds to comments by Tryon (2016) regarding the nature of mechanism and free will in psychological science. It is agreed that psychological science has problems with the presentation of mechanistic theories that are simplistic and based on weak data. However, it is argued that a systematic effort to study free will is a worthwhile enterprise. Current data provide evidence both for and against the existence of free will. Sophisticated analysis may provide routes to reconcile determinism with free will in newer and more ecologically valid theory.
