One of the key sources of support for the view that challenging people's beliefs about free will may undermine moral behavior is a classic study by Vohs and Schooler (2008). These authors reported that exposure to certain prompts suggesting that free will is an illusion increased cheating behavior among study participants. In the present paper, we report several attempts to replicate this influential and widely cited work. Over a series of four high-powered studies (three preregistered) we

Our efforts were largely unsuccessful. We suggest that manipulating free will beliefs in a robust way is more difficult than has been implied by prior work, and that the proposed link with immoral behavior may be similarly tenuous.
