Negative perceptions of outsourcing to artificial intelligence
As artificial intelligence (AI) tools become increasingly integrated into daily life, people are beginning to outsource not only professional tasks but also socio-relational ones. Large language models like ChatGPT can generate wedding vows, speeches, and personal messages, raising questions about how individuals who use AI for such tasks are perceived by others. In this paper, we conduct six pre-registered studies with British participants (N = …
Prosocial Phenotype Predicts Political Views on Hierarchy and Redistribution 18 Months Later
Cross-sectional research has identified robust correlations between prosocial behavior in economic games and political views, but this research is limited in its ability to draw causal inferences. Here, we conducted a longitudinal cross-lagged panel study of prosociality and political views with a New Zealand sample ( n = 631). Across two waves separated by 18 months, we measured self-reported political views and employed a battery of economic ga…
Validation of the Mini‐Ipip6 Short‐Form Personality Inventory: Honesty‐Humility Predicts Cooperation in Economic Games
This study validated the Mini‐IPIP6 short‐form measure of Honesty‐Humility to predict cooperative behaviour in online economic games. A subsample of participants from the New Zealand Attitudes and Values Study completed four online economic games for money, in addition to the Mini‐IPIP6 six‐factor personality inventory ( N = 979). Cooperative behaviour was modelled as a latent variable reflecting behaviour across the four games. Honesty‐Humility …
A many-analysts approach to the relation between religiosity and well-being
The relation between religiosity and well-being is one of the most researched topics in the psychology of religion, yet the directionality and robustness of the effect remains debated. Here, we adopted a many-analysts approach to assess the robustness of this relation based on a new cross-cultural dataset (N=10,535 participants from 24 countries). We recruited 120 analysis teams to investigate (1) whether religious people self-report higher well-…
Being specific about generalisability
Partner choice does not predict prosociality across countries
Why does human prosociality vary around the world? Evolutionary models and laboratory experiments suggest that possibilities for partner choice (i.e. the ability to leave unprofitable relationships and strike up new ones) should promote cooperation across human societies. Leveraging the Global Preferences Survey ( n = 27,125; 27 countries) and the World Values Survey ( n = 54,728; 32 countries), we test this theory by estimating the associations …
Coevolution of religious and political authority in Austronesian societies
Authority, an institutionalized form of social power, is one of the defining features of the large-scale societies that evolved during the Holocene. Religious and political authority have deep histories in human societies and are clearly interdependent, but the nature of their relationship and its evolution over time is contested. We purpose-built an ethnographic dataset of 97 Austronesian societies and used phylogenetic methods to address two lo…
