  Baumeister and colleagues found that provoking disbelief in free will seems to cause various negative effects. The authors concluded, in their paper, that it is belief in determinism that causes those negative effects. Kathleen Vohs has found that those whose belief in free will had been eroded were more likely to cheat. In a study conducted by Roy Baumeister, after participants read an article arguing against free will, they were more likely to lie about their performance on a test where they would be rewarded with cash. Provoking a rejection of free will has also been associated with increased aggression and less helpful behaviour. However, although these initial studies suggested that believing in free will is associated with more morally praiseworthy behavior, more recent studies (including direct, multi-site replications) with substantially larger sample sizes have reported contradictory findings (typically, no association between belief in free will and moral behavior), casting doubt over the original findings.
  
  An alternative explanation builds on the idea that subjects tend to confuse determinism with fatalism... What happens then when agents' self-efficacy is undermined? It is not that their basic desires and drives are defeated. It is rather, I suggest, that they become skeptical that they can control those desires; and in the face of that skepticism, they fail to apply the effort that is needed even to try. If they were tempted to behave badly, then coming to believe in fatalism makes them less likely to resist that temptation.

  Moreover, whether or not these experimental findings are a result of actual manipulations in belief in free will is a matter of debate. First of all, free will can at least refer to either libertarian (indeterministic) free will or compatibilistic (deterministic) free will. Having participants read articles that simply "disprove free will" is unlikely to increase their understanding of determinism, or the compatibilistic free will that it still permits. In other words, experimental manipulations purporting to "provoke disbelief in free will" may instead cause a belief in fatalism, which may provide an alternative explanation for previous experimental findings. To test the effects of belief in determinism, it has been argued that future studies would need to provide articles that do not simply "attack free will", but instead focus on explaining determinism and compatibilism.
  
  Baumeister and colleagues also note that volunteers disbelieving in free will are less capable of counterfactual thinking. This is worrying because counterfactual thinking ("If I had done something different...") is an important part of learning from one's choices, including those that harmed others. Again, this cannot be taken to mean that belief in determinism is to blame; these are the results we would expect from increasing people's belief in fatalism.
  
  Along similar lines, Tyler Stillman has found that belief in free will predicts better job performance.
