Taken together, we present a new toolkit for measuring individual- and group-level social preferences, show that both are shaped by conflict experiences and perceptions, and demonstrate that they predict conflict engagement across diverse samples and group memberships. (6/7)

In a quasi-experimental Study 5 among US participants, we show that parochialism is elevated in high- relative to low-conflict group pairings, whereas altruism appears comparatively less depended on perceived conflict intensity. (5/7)

In Study 1, we validate our measurement toolkit, showing that altruism and parochialism are separate social preferences. In Studies 2-3, we find that individual-and group-level preferences independently predict participation in real-world conflict (football derby fans and political camps). (3/7)

Classic “parochial altruism” models assume two distinct preferences drive conflict participation:
𝗔𝗹𝘁𝗿𝘂𝗶𝘀𝗺: helping one’s ingroup at a personal cost,
𝗣𝗮𝗿𝗼𝗰𝗵𝗶𝗮𝗹𝗶𝘀𝗺: favoring ingroups over outgroups.

However, when we induced empathy for future generations in the between-generations condition, antibiotic overuse in case of mild infections dropped. This suggests that how we frame the dilemma—and empathy-based interventions—can help promote more responsible antibiotic use. (3)

What a great pleasure to host the Behavioural Insights and Antimicrobial Resistance Workshop last week in Vienna. Many insightful talks and discussions on relevant topics, like AMR knowledge, patient expectations and behaviour, prescribers' behaviour, and challenges in LMICs.

Why the shift? 🧠 We propose and test a transition heuristic explanation (following Kahneman & Sugden; doi.org/10.1007/s106...): Before implementation, people focus on personal losses; after implementation, they shift focus to societal gains (e.g., public health, climate benefits).

Using secondary survey (N = 49,000+) and experimental data (6 studies, total N = 4,000+), we find that resistance to system-level policies is stronger before than after their implementation. This holds across various contexts like:
🚗 car bans, 💉 vaccination mandates, 🚫 speed limits, 🚬 smoking bans
🚗 car bans, 💉 vaccination mandates, 🚫 speed limits, 🚬 smoking bans

We found a statistically large effect of the experiential VR intervention on increasing intentions of prudent antibiotics use, which remained even one week after the study and exceeded the effectiveness of the other two treatments.

We found a statistically large effect of the experiential VR intervention on increasing intentions of prudent antibiotics use, which remained even one week after the study and exceeded the effectiveness of the other two treatments.
In our preregistered RCT (N = 239 young adults), we tested the effect of this experiential VR intervention against two other treatments that solely provided information about AMR, either via VR or a tablet. Outcome measure was participants' intention of prudent antibiotics use.
