The hand of God or the hand of Maradona? Believing in free will increases perceived intentionality of others’ behavior

It Is Belief in Dualism, and Not Free Will, That Best Predicts Helping: A Conceptual Replication and Extension of Baumeister et al. (2009)

Previous research found that experimentally reducing people's belief in free will affects social behaviors. However, more recent investigations could not replicate several findings in this literature. An explanation for the mixed findings is that free will beliefs are related to social behaviors on a correlational level, but experimental manipulations are not able to detect this relation. To test this interpretation, we conceptually replicated and extended a landmark study in the free will belief literature originally conducted by Baumeister et al. In five studies (total N = 1,467), we investigated whether belief in free will predicts helping behavior in comparison to other beliefs related to free will. Overall, our results support the original findings, as belief in free will correlated with helping behavior. However, the results also show that the best predictor of helping behavior is not belief in free will but belief in dualism. Theoretical implications are discussed.

The role of free will beliefs in social behavior: Priority areas for future research

Recent research has examined the consequences that holding views about free will has on social behavior. Specifically, through manipulating people's belief in free will, researchers have tested the psychological and behavioral consequences of free will belief change. However, findings of such manipulations have been shown to be relatively small and inconsistent. The purpose of this paper is to outline four key areas for researchers in this area to consider. We believe considering these areas will give a more nuanced understanding of the role of free will beliefs.

Does belief in free will influence biological motion perception?

Previous research suggests that belief in free will correlates with intentionality attribution. However, whether belief in free will is also related to more basic social processes is unknown. Based on evidence that biological motion contains intentionality cues that observers spontaneously extract, we investigate whether people who believe more in free will, or in related constructs, such as dualism and determinism, would be better at picking up such cues and therefore at detecting biological agents hidden in noise, or would be more inclined to detect intentionality cues and therefore to detect biological agents even when there are none. Signal detection theory was used to measure participants' ability to detect biological motion from scrambled background noise (d') and their response bias (c) in doing so. In two experiments, we found that belief in determinism and belief in dualism, but not belief in free will, were associated with biological motion perception. However, no causal effect was found when experimentally manipulating free will-related beliefs. In sum, our results show that biological motion perception, a low-level social process, is related to high-level beliefs about dualism and determinism.

Manipulating Belief in Free Will and Its Downstream Consequences: A Meta-Analysis

Ever since some scientists and popular media put forward the idea that free will is an illusion, the question has risen what would happen if people stopped believing in free will. Psychological research has investigated this question by testing the consequences of experimentally weakening people's free will beliefs. The results of these investigations have been mixed, with successful experiments and unsuccessful replications. This raises two fundamental questions: Can free will beliefs be manipulated, and do such manipulations have downstream consequences? In a meta-analysis including 145 experiments (95 unpublished), we show that exposing individuals to anti-free will manipulations decreases belief in free will and increases belief in determinism. However, we could not find evidence for downstream consequences. Our findings have important theoretical implications for research on free will beliefs and contribute to the discussion of whether reducing people's belief in free will has societal consequences.

Automatic or controlled: How does disbelief in free will influence cognitive functioning?

Most people believe in free will. Past research has indicated that reducing this belief has numerous downstream consequences including everyday outcomes as well as neural and cognitive correlates associated with a reduction of self-control. However, the exact mechanisms through which a reduction in free will belief affects self-control are still a matter of investigation. In the present registered report, we used a task switching paradigm to examine whether reducing belief in free will makes people less controlled or whether it enhances their reliance on automatic impulses. Using Bayesian sequential analysis, we failed to conceptually replicate the previous link between free will belief and cognitive control. Our registered report plan mostly accumulated substantial evidence supporting the null hypothesis. That is, diminished belief in free will does neither impact control nor automaticity. Theoretical implications of this finding are discussed.

Belief in Free Will Is Related to Internal Attribution in Self-Perception

Past research indicates that individuals’ belief in free will is related to attributing others’ behavior to internal causes. An open question is whether belief in free will is related to the attribution of one’s own action. To answer this question, we tested two opposing predictions against each other by assessing the relation of belief in free will with the self-serving bias—individuals’ tendency to attribute personal success more strongly to internal forces and failure to external forces. The resource hypothesis predicts that a higher endorsement in free will belief relates to a lower self-serving bias. The intention attribution hypothesis predicts that belief in free will relates to higher internal attributions, as compared with external attributions, irrespective of success and failure. Meta-analytic evidence across five high-powered studies (total N = 1,137) supports the intention attribution hypothesis, but not the resource hypothesis (materials and data are available on the Open Science Framework: https://osf.io/2a89c/ ).

Imitation and interindividual differences: Belief in free will is not related to automatic imitation

It is well known that individuals have the tendency to automatically imitate each other and that such imitative behavior is fostered by perceiving intentions in others' actions. That is, past research has shown that perceiving an action as internally driven enhances the shared representation of observed and executed actions increasing automatic imitation. An interpersonal factor that increases the perception that a behavior is internally driven is belief in free will. Consequently, we hypothesized that the more individuals believe in free will, the more they automatically imitate others. To test this prediction, we conducted two high-powered (total N = 642) and preregistered studies in which we assessed automatic imitation with the imitation-inhibition task. Contrary to our predictions, belief in free will did not correlate with automatic imitation. This finding contributes to current findings challenging the assumption that automatic imitation is modulated by interindividual differences. Further theoretical implications are discussed.

Free to blame? Belief in free will is related to victim blaming

The more people believe in free will, the harsher their punishment of criminal offenders. A reason for this finding is that belief in free will leads individuals to perceive others as responsible for their behavior. While research supporting this notion has mainly focused on criminal offenders, the perspective of the victims has been neglected so far. We filled this gap and hypothesized that individuals' belief in free will is positively correlated with victim blaming-the tendency to make victims responsible for their bad luck. In three studies, we found that the more individuals believe in free will, the more they blame victims. Study 3 revealed that belief in free will is correlated with victim blaming even when controlling for just world beliefs, religious worldviews, and political ideology. The results contribute to a more differentiated view of the role of free will beliefs and attributed intentions.

Professional Judges’ Disbelief in Free Will Does Not Decrease Punishment

There is a debate in psychology and philosophy on the societal consequences of casting doubts about individuals’ belief in free will. Research suggests that experimentally reducing free will beliefs might affect how individuals evaluate others’ behavior. Past research has demonstrated that reduced free will beliefs decrease laypersons’ tendency toward retributive punishment. This finding has been used as an argument for the idea that promoting anti-free will viewpoints in the public media might have severe consequences for the legal system because it may move judges toward softer retributive punishments. However, actual implications for the legal system can only be drawn by investigating professional judges. In the present research, we investigated whether judges ( N = 87) are affected by reading anti-free will messages. The results demonstrate that although reading anti-free will texts reduces judges’ belief in free will, their recommended sentences are not influenced by their (manipulated) belief in free will.

The Illusion of Time: Testing the Bidirectional Relationship Between Belief in Free Will and Temporal Horizons

The current research examined the bidirectional relationship between belief in free will and perceptions of time. Studies 1 and 2 explored the association between free will beliefs (FWB) and future time perspective (FTP) in correlational and longitudinal studies, respectively. Results indicated a positive relationship between the two constructs. Study 3 manipulated FTP and assessed FWB. Study 4 manipulated FWB and assessed FTP about current goal-pursuit. While manipulating FTP did not directly influence FWB, attenuating FWB led participants to perceive time as more limited to accomplish their goals. Exploratory mediation suggests that the perception of increased paths to successful goal-pursuit accounts for this relationship. The interplay between FWB and FTP is discussed.

It’s in Your Control: Free Will Beliefs and Attribution of Blame to Obese People and People with Mental Illness

People’s belief in free will is shown to influence the perception of personal control in self and others. The current study tested the hypothesis that individuals who believe in free will attribute stronger personal blame to obese people and to people with mental illness (schizophrenia) for their adverse health outcomes. Results from a sample of 1110 participants showed that the belief in free will subscale is positively correlated with perceptions of the controllability of these adverse health conditions. The findings suggest that free will beliefs are correlated with attribution of blame to people with obesity and mental health issues. The study contributes to the understanding of the possible negative implications of people’s free will beliefs.
