Free love? On the relation between belief in free will, determinism, and passionate love

Prescription for Love: An Experimental Investigation of Laypeople's Relative Moral Disapproval of Love Drugs

New technologies regularly bring about profound changes in our daily lives. Romantic relationships are no exception to these transformations. Some philosophers expect the emergence in the near future of love drugs: a theoretically achievable biotechnological intervention that could be designed to strengthen and maintain love in romantic relationships. We investigated laypeople's resistance to the use of such technologies and its sources. Across two studies (Study 1, French and Peruvian university students, N after exclusion = 186; Study 2, Amazon Mechanical Turk sample, N after exclusion = 693, pre-registered), we found that the use of love drugs designed to strengthen and maintain love in romantic relationships are considered as more morally problematic than psychological therapy with the same aim. In Study 2, we show that this last effect is partially due to the fact that the love resulting from the use of love drugs is perceived as less authentic, intense, and durable. We discuss the specific role of authenticity in the relative moral disapproval of love drugs.

Do people have control over the decisions they make? Psychometric properties of the Italian version of the free will and scientific determinism questionnaire (FAD-plus-I)

The FAD-Plus is a multidimensional measure of lay Beliefs in Free Will, Fatalistic Determinism, Scientific Determinism, and Unpredictability. This study had four aims: First, to test the factor structure of the Italian translation of the FAD-Plus in a sample of adults from the community, using structural equation modeling. Second, to test the reliability of the four scales. Third, to investigate gender invariance in item thresholds and factor loadings. Fourth, to analyze the criterion-related validity of the measure. Participants were 328 adults from the community, specifically 173 females and 155 males aged 18–56 years. Results showed that the proposed bifactor model tested by means of exploratory structural equation modeling fitted the data well (CFI = 1.000, RMSEA = 0.000, SRMR = 0.045), and that all the scales were reliable (Omega = .91–.98). Gender invariance was established, with no significant differences in fit indices between females and males. Beliefs in Free Will correlated positively and lowly to moderately with Aggressiveness (rs = .12), Extraversion (.25), Self- (.40) and Other-Representations of adult attachment (.43). Beliefs in Fatalistic Determinism correlated positively and lowly with Other-Representations (rs = .11), whereas its correlations with Aggressiveness, Extraversion, and Neuroticism were close to zero. In conclusion, these findings provide researchers and practitioners with evidence on a reliable and valid measure of Beliefs in free will and determinism in the Italian context, considered as predictors of individuals’ autonomy, effective coping, and prosocial behavior, of foremost importance for prevention and intervention in the community, particularly in occupational, legal, and clinical settings.

The Association Between Believing in Free Will and Subjective Well-Being Is Confounded by a Sense of Personal Control

The extent to which an individual believes in free will is associated with a number of positive life outcomes, including their own subjective well-being. However, it is not known whether the belief that one has free will per se is uniquely associated with subjective well-being over and above potential confounding variables. We examined a sense of personal control as one such confound-specifically, whether the association between free will belief (FWB) and subjective well-being is based, in part, on the degree to which an individual feels a sense of personal control over their life. In Study, 1 trait-level belief in personal control significantly uniquely predicted satisfaction with life and stress, over and above the contribution of FWB. In Study 2, within-person daily fluctuations in stress and depression were not significantly predicted by daily changes in FWB over and above the contribution of personal control/choice. The findings provide new insight into the relationship between FWB and subjective well-being.
