Experimental philosophy and the incentivisation challenge : a proposed application of the Bayesian Truth Serum

A key challenge in experimental social science research is the incentivisation of subjects such that they take the tasks presented to them seriously and answer honestly. If subject responses can be evaluated against an objective baseline, a standard way of incentivising participants is by rewarding them monetarily as a function of their performance. However, the subject area of experimental philosophy is such that this mode of incentivisation is not applicable as participant responses cannot easily be scored along a true-false spectrum by the experimenters. We claim that experimental philosophers’ neglect of and claims of unimportance about incentivisation mechanisms in their surveys and experiments has plausibly led to poorer data quality and worse conclusions drawn overall, potentially threatening the research programme of experimental philosophy in the long run. As a solution to this, we propose the adoption of the Bayesian Truth Serum, an incentive-compatible mechanism used in economics and marketing, designed for eliciting honest responding in subjective data designs by rewarding participant answers that are surprisingly common. We argue that the Bayesian Truth Serum (i) adequately addresses the issue of incentive compatibility in subjective data research designs and (ii) that it should be applied to the vast majority of research in experimental philosophy. Further, we (iii) provide an empirical application of the method, demonstrating its qualified impact on the distribution of answers on a number of standard experimental philosophy items and outline guidance for researchers aiming to apply this mechanism in future research by specifying the additional costs and design steps involved.Publisher PDFPeer reviewe

What's up with anti-natalists? An observational study on the relationship between dark triad personality traits and anti-natalist views

In the past decade, research on the dark triad of personality (Machiavellianism, narcissism, and psychopathy) has demonstrated a strong relationship to a number of socially aversive moral judgments such as sacrificial utilitarian decisions in moral dilemmas. This study widens the scope of this research program and investigates the association between dark triad personality traits and anti-natalist views, i.e., views holding that procreation is morally wrong. The results of this study indicate that the dark triad personality traits of Machiavellianism and psychopathy are strongly associated with anti-natalist views. Further, depression is found to be both standing independently in a relationship with anti-natalist views as well as functioning as a mediator in the relationships between Machiavellianism/psychopathy and anti-natalist views. This pattern was replicated in a follow-up study. These findings add to the literature on dark triad personality traits and their relationship to moral judgments, suggesting that personality and mood play a substantive part in variation in anti-natalist views in a lay population.Publisher PDFPeer reviewe

Social sciences in crisis : on the proposed elimination of the discussion section

The social sciences are facing numerous crises including those related to replication, theory, and applicability. We highlight that these crises imply epistemic malfunctions and affect science communication negatively. Several potential solutions have already been proposed, ranging from statistical improvements to changes in norms of scientific conduct. In this paper, we propose a structural solution: the elimination of the discussion section from social science research papers. We point out that discussion sections allow for an inappropriate narrativization of research that disguises actual results and enables the misstatement of true limitations. We go on to claim that removing this section and outsourcing it to other publications provides several epistemic advantages such as a division of academic labour, adversarial modes of progress, and a better alignment of the personal aims of scientists with the aims of science. After responding to several objections, we conclude that the potential benefits of moving away from the traditional model of academic papers outweigh the costs and have the potential to play a part in addressing the crises in the social sciences alongside other reforms. As such, we take our paper as proffering a further potential solution that should be applied complimentarily with other reform movements such as Open Science and hope that our paper can start a debate on this or similar proposals.Publisher PDFPeer reviewe

Moral decision-making : essays from philosophy and economics

This thesis investigates moral decision-making from the two disciplinary angles of philosophy and economics. Moral decision-making includes moral judgements (e.g., judgements as to the moral (im-)permissibility of actions) and moral behaviour (e.g., charitable giving). The topic choice throughout this thesis was primarily motivated by global priorities research, ranging from population ethics to effective charitable giving. The first three chapter primarily focus on experimental philosophy. In them, I (a) investigate the relationship between the dark triad personality traits, psychopathy, Machiavellianism, and narcissism and anti-natalist views, finding that those high on dark triad traits are significantly more likely to endorse anti-natalist views. I also find that this relationship is mediated by depression. Then, I (b) study reflective equilibrium behaviour in the context of population ethics, finding that in accordance with theory, concrete case judgements play a revisionary role with respect to endorsements of general moral principles. Further, I (c) argue that research in psychology and experimental philosophy has not adequately dealt with the issue of incentivisation. I then go on to conduct an empirical showcase of the Bayesian Truth Serum in this context, demonstrating impacts on response behaviour. The last three chapters focus on experimental economics. I (d) analyse charitable giving behaviour under normative uncertainty and show that randomly allocated expert advice is undervalued by donors, though can impact donation behaviour and reduce uncertainty. Then, I (e) investigate the effect of morally demanding charitable solicitations on donor behaviour, finding that while moral arguments raise donations, increases of moral demandingness do not. Lastly, I (f) analyse the predictors of donating to probabilistic and ambiguous charities as opposed to more reliable ones, failing to find an impact of risk and ambiguity uncertainty. Overall, I hope that the work presented in this thesis is able to advance global priorities research into these topics

Social and moral psychology of COVID-19 across 69 countries

The COVID-19 pandemic has affected all domains of human life, including the economic and social fabric of societies. One of the central strategies for managing public health throughout the pandemic has been through persuasive messaging and collective behaviour change. To help scholars better understand the social and moral psychology behind public health behaviour, we present a dataset comprising of 51,404 individuals from 69 countries. This dataset was collected for the International Collaboration on Social & Moral Psychology of COVID-19 project (ICSMP COVID-19). This social science survey invited participants around the world to complete a series of moral and psychological measures and public health attitudes about COVID-19 during an early phase of the COVID-19 pandemic (between April and June 2020). The survey included seven broad categories of questions: COVID-19 beliefs and compliance behaviours; identity and social attitudes; ideology; health and well-being; moral beliefs and motivation; personality traits; and demographic variables. We report both raw and cleaned data, along with all survey materials, data visualisations, and psychometric evaluations of key variables

National identity predicts public health support during a global pandemic

Changing collective behaviour and supporting non-pharmaceutical interventions is an important component in mitigating virus transmission during a pandemic. In a large international collaboration (Study 1, N = 49,968 across 67 countries), we investigated self-reported factors associated with public health behaviours (e.g., spatial distancing and stricter hygiene) and endorsed public policy interventions (e.g., closing bars and restaurants) during the early stage of the COVID-19 pandemic (April-May 2020). Respondents who reported identifying more strongly with their nation consistently reported greater engagement in public health behaviours and support for public health policies. Results were similar for representative and non-representative national samples. Study 2 (N = 42 countries) conceptually replicated the central finding using aggregate indices of national identity (obtained using the World Values Survey) and a measure of actual behaviour change during the pandemic (obtained from Google mobility reports). Higher levels of national identification prior to the pandemic predicted lower mobility during the early stage of the pandemic (r = −0.40). We discuss the potential implications of links between national identity, leadership, and public health for managing COVID-19 and future pandemics.publishedVersio

Predicting attitudinal and behavioral responses to COVID-19 pandemic using machine learning

At the beginning of 2020, COVID-19 became a global problem. Despite all the efforts to emphasize the relevance of preventive measures, not everyone adhered to them. Thus, learning more about the characteristics determining attitudinal and behavioral responses to the pandemic is crucial to improving future interventions. In this study, we applied machine learning on the multinational data collected by the International Collaboration on the Social and Moral Psychology of COVID-19 (N = 51,404) to test the predictive efficacy of constructs from social, moral, cognitive, and personality psychology, as well as socio-demographic factors, in the attitudinal and behavioral responses to the pandemic. The results point to several valuable insights. Internalized moral identity provided the most consistent predictive contribution—individuals perceiving moral traits as central to their self-concept reported higher adherence to preventive measures. Similar results were found for morality as cooperation, symbolized moral identity, self-control, open-mindedness, and collective narcissism, while the inverse relationship was evident for the endorsement of conspiracy theories. However, we also found a non-neglible variability in the explained variance and predictive contributions with respect to macro-level factors such as the pandemic stage or cultural region. Overall, the results underscore the importance of morality-related and contextual factors in understanding adherence to public health recommendations during the pandemic.Peer reviewe
