Much previous theory and evidence in both social and evolutionary psychology has been equivocal and inconsistent regarding whether in-group altruism should predict out-group hostility, and whether this effect should be positive or negative in direction. A "slow" Life History (LH) strategy emphasizes both kin-selected altruism and reciprocal altruism as means of investing heavily in offspring, blood relatives, and mutualistic social relationships with both kith and kin. We therefore investigated whether a slow LH strategy, as a measurable individual-difference variable favoring in-group altruism (positive ethnocentrism), should predict out-group hostility (negative ethnocentrism), and what the direction of the hypothesized effect would be. We found that a multivariate latent variable representing slow LH strategy served as a protective factor against a latent variable representing Negative Ethnocentrism. These results were replicated in the United States of America and in the Republic of Costa Rica using Multisample Structural Equation Model with cross-sample equality constraints.
Both altruistic and ecological behaviours are considered prosocially driven behaviours, but our understanding of what motivates action in either the human or ecological domain is still in its infancy. Our goal was to assess connection to nature, connection to people, and connection to country as mediators of the relationship between prosocial propensity and prosocial behaviours in both the ecological and human domains. This study used honesty-humility as an indicator of prosocial propensity. Data for the study were collected through online surveys in Spanish. The survey was answered by 438 adolescent participants aged 11–19 years. The present study demonstrates that personal prosocial propensity can be directed to a particular domain of prosocial behaviour (ecological or altruistic) through the individual’s connection to the relevant domain. Specifically, the effect of prosocial propensity on ecological behaviour was positively mediated by connection to people and connection to nature, but negatively mediated by connection to country. For altruistic behaviour, the effect of prosocial propensity was positive via connection to people, nature, and country. Future research is called for, in particular, to examine the role of connection to country in ecological behaviour.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
