On the foundations of beliefs in free will: intentional binding and unconscious priming in self-agency

The concept of an ability to make choices and to determine one's own outcomes fits well with experiences that most people have, and these experiences form the basis for beliefs in free will. However, the existence of conscious free will is challenged by modern research findings highlighting the unconscious origins of goal-directed behavior that gives rise to free-will beliefs. This report expands on these insights by revealing that both conscious and unconscious processes play an important role in free-will beliefs. Specifically, Experiment 1 demonstrates that free-will beliefs are strengthened when conscious intentions to produce action outcomes bind the perception of action and outcome together in time. Experiment 2 shows that these beliefs are strengthened when unconscious priming of action outcomes creates illusory experiences of self-agency when the primed outcomes occur. Together, these findings suggest that beliefs in free will are associated with self-agency and are enhanced by both conscious and unconscious information processing of goal-directed behavior.
