Groups as organisms: Implications for therapy and training

Multilevel cultural evolution: From new theory to practical applications

Evolutionary science has led to many practical applications of genetic evolution but few practical uses of cultural evolution. This is because the entire study of evolution was gene centric for most of the 20th century, relegating the study and application of human cultural change to other disciplines. The formal study of human cultural evolution began in the 1970s and has matured to the point of deriving practical applications. We provide an overview of these developments and examples for the topic areas of complex systems science and engineering, economics and business, mental health and well-being, and global change efforts.

Strategies of prosociality: Comparing Nordic and Slavonic altruism toward Ukrainian refugees

Nordic high-trust societies are underpinned by prosociality, a term denoting cooperation and working for the good of others. State-funded voluntarism provides opportunities for altruism that appears to contribute to the Nordics' exceptional level of well-being. Altruists are rewarded by a warm, lasting affect that enhances personal well-being, thus motivating further prosociality. Humanity's evolutionary past coded into us a desire to strengthen our community by helping those in need-a biocultural drive that is corrupted when authoritarian regimes enforce unselfish behavior on disempowered populations. Such coercive altruism has a line of adverse long-term consequences for communal functionality and individual flourishing. Our study examines how sociocultural context influences people's prosocial strategies, and how sharing insights and practices from democratic and authoritarian traditions can lead to new, revitalized forms of altruism. Our in-depth interviews (n = 32) of Nordic and Slavonic helpers of Ukrainian refugees in Norway (1) illuminate the impact of culture and memory on altruistic practices, (2) define points of tension between systemic and anti-systemic modes of prosociality, and (3) identify cross-cultural interactions that generate trust, well-being, and social innovation. The post-communist experience of the Slavonic informants motivated anti-systemic altruism, which highlights spontaneity, improvisation, and occasional rule breaking. Norwegian systemic altruism is based on trust, efficacy, and rule-following. Our evolutionary approach to cultural psychology substantiates how important it is for development and immigration policies to align our knowledge of human nature with insights into the workings of cultural legacies. A better understanding of the biocultural mainsprings of altruism could be of crucial importance in our era of reemerging authoritarianism and increasing migration.

A multilevel selection model for prosocial well-being

This article proposes an evolutionary model for well-being informed by multilevel selection. We posit that people's subjective assessment of their own quality of life is the sum their happiness, which is related to individual selection, and their sense of having a meaningful life, which is related to group selection. Conceptualizing life quality as "Happiness + Meaning = Well-being" offers insights into how the human well-being system helps people navigate between individual and group needs. We define happiness as the cluster of affects that reward individuals for solving adaptively relevant problems. We approach meaning as a reward individuals experience when contributing to their community. While people derive happiness from cooperation and competition, meaning originates from prosocial (cooperative/altruistic) behavior. Since increased within-group competition often reduces societal well-being, public policy should aim at cooperative means for good living. Our model brings attention to these dynamics. The Nordic countries, which score highest on quality of life, facilitate multilevel well-being, that is, individual prosperity and altruistic opportunity. Our preliminary quantitative study confirmed the correlation between some markers of prosociality and well-being at a national level. To investigate the psychological mechanisms behind this correlation, we conducted in-depth interviews of Nordic and Slavonic helpers of Ukrainian refugees in Norway (n = 32). A primary ambition was to illuminate how the human quest for meaning contributes both to individual flourishing and group selection. In line with Nesse's view on happiness not as an affect meant to be maximized, but an evolutionary signal, we use a qualitative approach that allows for a deeper understanding of how individuals adapt to these signals. Our findings suggest that happiness is transient so that the well-being system's signal sensitivity can be preserved. Meaning is enduring since it assesses and reinforces social belonging. These insights are relevant for our era's turn toward more holistic development policies. Compared to often materialistic, competition-driven happiness pursuits, meaning-driven well-being is a more sustainable alternative for individuals, communities, and the planet.
