How can states credibly commit to peace and assure other countries? One source of credible assurance identified in previous studies is the cost to a state’s international reputation. When a state violates a prior commitment to peace, it suffers reputational damage, which can be costly in various ways. These reputational costs, in turn, serve as a tying-hands signal that enhances the credibility of peaceful commitments. Nonetheless, empirical research on whether and under what conditions such reputation costs arise remains limited. To address this gap, this study conducts a preregistered survey experiment in the United States, using a hypothetical scenario involving military buildups by China and Japan. The results indicate that violating commitments to peace undermines the credibility of future commitments, particularly when the violator is a rival country. These findings suggest that, with some limitations, international reputation costs can serve as a reliable mechanism for ensuring the credibility of assurances.

The number of studies examining gender differences in the social relationship rewards associated with costly religious practice has been surprisingly low. Here, we use data from 289 residents of an agricultural Tibetan village to assess whether individuals are more inclined to establish supportive relationships with religious individuals in general and to investigate the gender disparities in the relationship between religiosity and personal network characteristics. Our results reveal that participation in religious rituals contributes to the overall development of social support networks. The benefits to personal networks, however, seem to be contingent upon gender. For resource-intensive, infrequent religious rituals such as distant pilgrimages, males seem to benefit slightly more in terms of elevated in-degree values in their personal networks, despite similar levels of investment as females. In contrast, for daily, low-cost religious practices requiring ongoing participation, both genders obtain similar increases in in-degree values through regular engagement. It becomes more challenging for women to increase their status in communities when the effort invested in religious rituals yields smaller rewards compared with the same effort by men, contributing to ongoing gender inequality. These findings highlight the importance of examining the particular characteristics of religious rituals and the gender disparities in the associated rewards.

In large, impersonal moral orders many of us wish to maintain good will toward our fellow citizens only if we are reasonably sure they will maintain good will toward us. The mutual maintaining of good will, then, requires that we somehow communicate our intentions to one another. But how do we actually do this? The current paper argues that when we engage in moral responsibility practices—that is, when we express our reactive attitudes by blaming, praising, and resenting—we communicate a desire to maintain good will to those in the community we are imbedded in. Participating in such practices alone will not get the job done, though, for expressions of our reactive attitudes are often what economists call cheap talk. But when we praise and blame in cases of moral diversity, expressions of our reactive attitudes act as costly signals capable of solving our social dilemma.
