Free will has been the object of debate in the context of addiction given that addiction could compromise an individual’s ability to choose freely between alternative courses of action. Proponents of the brain-disease model of addiction have argued that a neuroscience perspective on addiction reduces the attribution of free will because it relocates the cause of the disorder to the brain rather than to the person, thereby diminishing the blame attributed to the person with an addiction. Others have worried that (...) such displacement of free will attribution would make the person with a drug addiction less responsible. Using the paradigmatic literature on the seductive allure of neuroscience explanations, we tested whether neuroscience information diminishes attributions of free will in the context of addiction and whether respondent characteristics influence these attributions and modulate the effect of neuroscience information. We performed a large-scale, web-based experiment with 2,378 German participants to explore how attributions of free will in the context of addiction to either alcohol or cocaine are affected by: (1) a text with a neurobiological explanation of addiction, (2) a neuroimage showing effects of addiction on the brain, and (3) a combination of a text and a neuroimage, in comparison to a control group that received no information. Belief in free will was measured using the FAD-Plus scale and was, subsequent to factor analysis, separated into two factors: responsibility and volition. The investigated respondent characteristics included gender, age, education, self-reported knowledge of neuroscience, substance-use disorder (SUD), and having a friend with SUD. We found that attributions of volition (in the cocaine-subsample) were reduced in the text and neuroimage-treatment compared to the control group. However, respondent characteristics such as education and self-reported knowledge of neuroscience were associated with lower attributions of responsibility for both substances, and education was associated with lower attribution of volition for the alcohol sub-sample. Interaction analyses showed that knowledge of neuroscience was found to generally decrease attribution of responsibility. Further research on attribution of free will should consider the effects of context and respondent characteristics, which appeared surprisingly larger than those induced by experimental treatments.

Previous research associates free will skepticism with adverse well-being effects. However, it is doubtful that skeptical participants in these studies disbelieved in the incompatibilist notion of what it means to have free will. This is one of the first studies to exclusively examine such skeptics. A sample of 167 participants who claimed to believe that there is no free will responded to an online survey. After examining whether participants in fact disbelieved in the incompatibilist concept, they were asked to describe (...) how their skepticism is affecting their personal life and well-being. Reoccurring themes were identified through thematic analysis. Positive consequences were most commonly reported, including increased compassion for others and oneself, being less controlling and more relaxed, as well as having more control through environmental awareness. Other participants felt unaffected by their disbelief and most frequently mentioned the persisting feeling of having free will as a reason. The most common negative implications were to feel less effective as an agent and to miss a sense of purpose. These findings may shed new light on how to handle the issue of free will in the public sphere as well as inform future research investigating incompatibilist free will skepticism. (shrink)

Whether people possess free will has been a long-lasting philosophical debate. Recent attention in social psychology has been given to the behavioral consequences of believing in free will. Research has demonstrated that manipulating free will beliefs has implications for many social behaviors. For example, free will belief manipulations have been associated with cheating, aggressiveness, and prejudice. Despite this work, some of these findings have failed to replicate. Testing theoretical predictions, such as whether believing in free will influences behavior, depends on (...) theoretical, auxiliary, statistical, and inferential assumptions (TASI). In this paper we apply the TASI category of assumptions to the free will belief debate. In doing so we demonstrate why these assumptions should be considered when appraising the influence of free will belief manipulations on free will beliefs and behavior. To provide a nuanced view of free will beliefs, we believe researchers should pay careful attention to these critical assumptions. (shrink)

Previous research suggests that free will beliefs and moral responsibility beliefs are strongly linked, yet ultimately distinct. Unfortunately, the most common measure of free will beliefs, the free will subscale (FWS) of the Free Will and Determinism Plus, seems to confound free will beliefs and moral responsibility beliefs. Thus, the present research (1,700 participants across two studies) details the development of a 2-factor FWS – the FWS-II – that divides the FWS into a free will subscale and a moral responsibility (...) subscale. The FWS-II showed good fit compared to standard fit thresholds and superior fit compared to the original FWS. The moral responsibility subscale was moderately correlated with general punitive attitudes and specific punitive assignments, even when controlling for the free will subscale. Conversely, the free will subscale was moderately correlated with conservativism and religiosity, even when controlling for the moral responsibility subscale. These results provide evidence that the FWS is better suited – psychometrically, theoretically, and practically – as a 2-factor measure of free will beliefs and moral responsibility beliefs than as a 1-factor measure of free will beliefs.

People across cultures consider everyday choices in the context of perceived various external life-determining forces: such as fate and gods (two teleological forces) and such notions as luck and chance (two non-teleological forces). There is little cross-cultural evidence (except for a belief in gods) showing how people relate these salient notions of life-determining forces to prosociality and a sense of well-being. The current paper provides preliminary cross-cultural data to address this gap. Results indicate that choice is the most important life-determining (...) factor. Regression analyses indicate that choice and belief in gods and fate emerged as significant predictors of prosociality towards strangers. Moreover, luck was a significant predictor of decreased prosociality. A relation between life-determining forces and life satisfaction followed the same pattern: choice, gods, and fate emerged as significant predictors of greater life satisfaction, whereas luck was associated with decreased life satisfaction. The overall pattern of results indicates that participants across different cultures might sense being bounded to share or not to care depending on the perceived intentional agency and meaning in the external forces.

Abstract:The question as to whether people with an addiction have control (and to what extent) over their addiction, and voluntarily decide to use substances is an ongoing source of controversy in the context of research on addiction, health policy and clinical practice. We describe and discuss a set of five challenges for further research into voluntariness (definition[s], measurement and study tools, first person perspectives, contextual understandings, and connections to broader frameworks) based on our own research experiences and those of others.
