  • Altruistic Behavior in Charitable Giving: a Comparison between Rational, Numerical, and Emotional Prompts
    Celso Vieira, Alex Wiegmann, Joachim Horvath
    Review of Philosophy and Psychology, 2025
    The evidence on the influence of rational appeals on moral behavior remains inconclusive. The opportunity to donate to a charity provides a fruitful applied case to test the details that might explain the mixed results. Previous studies have demonstrated the power of emotional appeals to induce participants to donate, while different rational appeals vary in their performance. Our paper presents the results of three pre-registered experiments comparing how much participants were willing to donate via direct cash transfers when exposed to different conditions. Experiment 1 tested five conditions. Three are vignette-based: Narrative, our emotional textual prompt, presents the testimony of an identified recipient, while Argument presents a Singer-style argument for charitable giving, and Facts consists of the numerical results of an evaluation of a cash transfer program. The other two conditions are based on perspective-taking exercises with either a reasonable donor or a suffering recipient, designed to elicit empathy with the beneficiaries. As predicted, the average amount donated in the control condition was significantly lower than in each of the other five conditions. Narrative performed best, significantly better than all other conditions. Among the rational conditions, Facts performed better descriptively. Its success is surprising given the poor performance of adding numerical information in other studies. After a replication with the vignette conditions in Experiment 2, we tested two variations of our Facts condition to explore how numerical information was taken into consideration. The numerical information in Large Numbers conveyed a highly effective intervention, while those in Small Numbers presented a barely positive impact. Since both variations generated roughly the same average donation amount, it seems that the numbers were not processed as numerical information.

  • Actual and Perceived Partisan Bias in Judgments of Political Misinformation as Lies
    Louisa M. Reins, Alex Wiegmann
    Social Psychological and Personality Science, 2025
    In times of what has been coined “post-truth politics,” people are regularly confronted with political actors who intentionally spread false or misleading information. The present article examines (a) to what extent partisans’ judgments of such behaviors as cases of lying are affected by whether the deceiving agent shares their partisanship (actual bias) and (b) to what extent partisans expect the lie judgments of others to be affected by a bias of this kind (perceived bias). In two preregistered experiments ( N = 1,040), we find partisans’ lie judgments to be only weakly affected by the partisanship ascribed to political deceivers, regardless of whether deceivers explicitly communicate or merely insinuate political falsehoods. At the same time, partisans expect their political opponents’ lie judgments to be strongly affected by the deceiving agents’ partisanship. Surprisingly, misperceptions of bias were also present in people’s predictions of bias within their own political camp.
  • Advances in experimental philosophy of lying
    Advances in Experimental Philosophy of Lying, 2025
    Lying is a familiar and morally important phenomenon. No matter if it is in election battles, in personal relationships or in the form of fake news – lying affects us almost every day. Showcasing cutting-edge research on the concept of lying, including work on blatant falsehoods, children’s concept of lying and deception in the courtroom, this interdisciplinary collection examines what it means to lie and how lying should be defined. Bringing together leading and rising scholars from philosophy, psychology, linguistics and anthropology, chapters present novel empirical findings using a variety of methods including experiments, armchair methods, corpus studies and fMRI. Advancing our understanding of the concept of lying, it also focuses on related concepts such as “fake news” and “bullshit”, as well as fundamental questions such as whether lying is morally worse than misleading. It is an essential resource for any student or scholar looking to stay ahead of the latest developments in the philosophy of lying and related fields in philosophy of language, ethics and moral philosophy, philosophy of law, moral psychology, linguistics and cognitive science.

  • Camouflaged liability: How the distinction between civilians and soldiers influences moral judgement of permissible harm in war
    Juan Carlos Marulanda‐Hernández, Alex Wiegmann, Michael R. Waldmann
    European Journal of Social Psychology, 2024
    Previous research has shown that people judge sacrificing a few people to save a larger number to be morally permissible when the intervention targets the threat but not when it targets the victims. We investigated whether this distinction according to the locus of intervention influences people's evaluations of wartime scenarios and whether such evaluations vary according to different types of victims (e.g., civilians vs. soldiers). We observed a significant effect of locus of intervention in situations in which a smaller number of civilians were sacrificed to save a larger number of civilians (Study 1; N = 142). However, the effect of locus of intervention was less pronounced in scenarios in which soldiers were sacrificed to save civilians (Studies 2 and 3; N = 173 and N = 841). A fourth experiment (N = 477) explored why participants treated soldiers and civilians differently. Participants believed that it is more permissible to sacrifice soldiers because they consent to being harmed.
