Protecting Public Goods or Helping Free Riders? A Real-Life Moral Dilemma in Interethnic and Intraethnic Encounters Open
People often protect public goods by sanctioning free riders. This occurs in simple situations in which protecting the public good does not conflict with other moral considerations. How do people navigate situations in which protecting the…

Behavioral experiments in computational social science Open
Behavioral experiments are rarely used as an empirical strategy in computational social science, where empirical studies typically focus on analyzing large-scale digital trace data. We argue that behavioral experiments have a role in compu…

Social norm dynamics and cooperation in changing groups Open
Social norms promote cooperation in human groups. How are these norms and cooperation affected when groups change due to new members arriving and old members leaving? In this review we highlight the scant literature that researches the eff…

Meta-Dominance Analysis – A Tool for the Assessment of the Quality of Digital Behavioural Data Open
We propose a simple yet comprehensive conceptual framework for the identification of different sources of error in research with digital behavioural data. We use our framework to map potential sources of error in 25 years of research on re…

Building a reputation for trustworthiness: Experimental evidence on the role of the feedback rate Open
In 25 years, research on reputation-based online markets has produced robust evidence on the existence of the so-called reputation effect, that is the positive relation between online traders’ reputations and these traders’ market success …

Signals of belonging: emergence of signalling norms as facilitators of trust and parochial cooperation Open
Mechanisms of social control reinforce norms that appear harmful or wasteful, such as mutilation practises or extensive body tattoos. We suggest such norms arise to serve as signals that distinguish between ingroup ‘friends' and outgroup ‘…

Cooperation, punishment, and group change in multilevel public goods experiments Open
Peer punishment is regarded as an important element in sustaining human cooperation for public good provision. Many behavioral experiments have shown that public good provision is higher if cooperation norms can be enforced by peer punishm…

The moral embeddedness of cryptomarkets: text mining feedback on economic exchanges on the dark web Open
Reputation systems promote cooperation in large-scale online markets for illegal goods. These so-called cryptomarkets operate on the Dark Web, where legal, social, and moral trust-building mechanisms are difficult to establish. However, fo…

Does Living in a Protected Area Reduce Resource Use and Promote Life Satisfaction? Survey Results from and Around Three Regional Nature Parks in Switzerland Open
Regional nature parks in Switzerland are, for the most part, protected areas that aim to promote sustainable development and residents’ well-being. In recent years, research on regional nature parks and comparable protected areas has focus…

The competitive advantage of sanctioning institutions revisited: A multilab replication Open
Is peer sanctioning a sustainable solution to the problem of human cooperation? We conducted an exact multilab replication (N = 1,008; 7 labs × 12 groups × 12 participants) of an experiment by Gürerk, Irlenbusch, and Rockenbach published i…

The Sanctioning Dilemma: A Quasi-Experiment on Social Norm Enforcement in the Train Open
Numerous laboratory experiments have established peer-sanctioning as an important driver of norm compliance and cooperation in human groups. However, systematic evidence of peer-sanctioning occurring in the field is still rare. Here we pre…

Generosity is a sign of trustworthiness – the punishment of selfishness is not Open
Peer-punishment is an important determinant of cooperation in human groups. It has been suggested that, at the proximate level of analysis, punitive preferences can explain why humans incur costs to punish their deviant peers. How punitive…

Technology use and norm change in online privacy: experimental evidence from vignette studies Open
We suggest that explaining privacy behaviors requires understanding not only individual attitudes, but also norms and trust. We propose: (1) the popularity of a potentially privacy-violating technology leads individuals to expect that othe…

“Take One for the Team!” Individual Heterogeneity and the Emergence of Latent Norms in a Volunteer's Dilemma Open
The tension between individual and collective interests and the provision of sanctioning mechanisms have been identified as important building blocks of a theory of norm emergence. Correspondingly, most investigations focus on how social n…
