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.

Common asset trusts to effectively steward natural capital and ecosystem services at multiple scales.

Ecosystems (natural capital) produce a range of benefits to humans. Natural capital is best thought of as common property since many of the ecosystem services it helps produce are non-rival and/or non-excludable. Private property regimes and markets alone are ineffective and inappropriate institutions to manage them sustainably. These systems can be better managed as commons, using more nuanced private and community property rights and Common Asset Trusts (CATs), with legal precedent in the Public Trust Doctrine. Effective CATs embody a generalized version of Elinore Ostrom's eight core design principles for sustainable commons management: (1) shared identity and purpose; (2) equitable distribution of contributions and benefits; (3) fair and inclusive decision-making; (4) monitoring agreed behaviours; (5) graduated responses; (6) fast and fair conflict resolution; (7) authority to self-govern; and (8) collaborative relations with other groups and spatial scales. Here, we describe a few existing and proposed systems that approximate effective CATs. We also suggest how Costa Rica can transform its existing payment for ecosystem services (PES) scheme into a national CAT. Finally, we describe how CATs can facilitate more fair and effective public/private partnerships (PPPs) to invest in natural capital and ecosystem services.

Core design principles for nurturing organization-level selection.

Dynamic relationships between individuals and groups have been a focus for evolutionary theorists and modelers for decades. Among evolutionists, selfish gene theory promotes reductionist approaches while multilevel selection theory encourages a context-sensitive approach that appreciates that individuals and groups can both matter. Among economists, a comparable contrast is found wherein the reductionist shareholder primacy theory most associated with Nobel laureate Milton Friedman is very different from the context-sensitive focus on managing common resources that Nobel laureate Elinor Ostrom pioneered. In this article, we examine whether the core design principles that Ostrom advanced can cultivate selection at supra-individual levels across different domains. We show that Ostrom's design principles that were forged in the context of managing natural resources are associated with positive outcomes for human social groups across a variety of functional domains.

Does your mindfulness benefit others? A systematic review and meta-analysis of the link between mindfulness and prosocial behaviour.

Mindfulness-based meditation practices have received substantial scientific attention in recent years. Mindfulness has been shown to bring many psychological benefits to the individual, but much less is known about whether these benefits extend to others. This meta-analysis reviewed the link between mindfulness - as both a personality variable and an intervention - and prosocial behaviour. A literature search produced 31 eligible studies (N = 17,241) and 73 effect sizes. Meta-analyses were conducted using mixed-effects structural equation models to examine pooled effects and potential moderators of these effects. We found a positive pooled effect between mindfulness and prosocial behaviour for both correlational (d = .73 CI 95% [0.51 to 0.96]) and intervention studies (d = .51 CI 95% [0.37 to 0.66]). For the latter, medium-sized effects were obtained across varying meditation types and intensities, and across gender and age categories. Preliminary evidence is presented regarding potential mediators of these effects. Although we found that mindfulness is positively related to prosociality, further research is needed to examine the mediators of this link and the contexts in which it is most pronounced.

Departing from the essential features of a high quality systematic review of psychotherapy: A response to Öst (2014) and recommendations for improvement.

Öst's (2014) systematic review and meta-analysis of Acceptance and Commitment Therapy (ACT) has received wide attention. On the basis of his review, Öst argued that ACT research was not increasing in its quality and that, in contradiction to the views of Division 12 of the American Psychological Association (APA), ACT is "not yet well-established for any disorder" (2014, p. 105). We conducted a careful examination of the methods, approach, and data used in the meta-analysis. Based in part on examinations by the authors of the studies involved, which were then independently checked, 91 factual or interpretive errors were documented, touching upon 80% of the studies reviewed. Comparisons of Öst's quality ratings with independent teams rating the same studies with the same scale suggest that Ost's ratings were unreliable. In all of these areas (factual errors; interpretive errors; quality ratings) mistakes and differences were not random: Ost's data were dominantly more negative toward ACT. The seriousness, range, and distribution of errors, and a wider pattern of misinterpreting the purpose of studies and ignoring positive results, suggest that Öst's review should be set aside in future considerations of the evidence base for ACT. We argue that future published reviews and meta-analyses should rely upon diverse groups of scholars rather than a single individual; that resulting raw data should be made available for inspection and independent analysis; that well-crafted committees rather than individuals should design, apply and interpret quality criteria; that the intent of transdiagnostic studies need to be more seriously considered as the field shifts away from a purely syndromal approach; and that data that demonstrate theoretically consistent mediating processes should be given greater weight in evaluating specific interventions. Finally, in order to examine substantive progress since Öst's review, recent outcome and process evidence was briefly examined.

Cognitive Defusion Predicts More Approach and Less Avoidance Coping With Stress, Independent of Threat and Self-Efficacy Appraisals.

OBJECTIVE: Recent evidence suggests that the way in which individuals relate to their aversive thoughts predicts behavioral effectiveness more than the content of such thoughts. This article is among the first to explore whether this is true for coping with stressful events. METHOD: Three studies with emerging adults (Study 1, N = 202) and adults (Study 2, N = 201; Study 3, N = 141) tested whether changes in how individuals relate to their stress-related thoughts, measured using the individual-difference construct of cognitive defusion, predicted more approach and less avoidance coping behavior, controlling for stress-related appraisals. RESULTS: We found that cognitive defusion predicted more approach coping (Studies 1 and 3) and less avoidance coping (Studies 2 and 3) following laboratory-induced stress (Study 1), naturally occurring monthly stress (Study 2), and daily stress (Study 3). These effects occurred independently of the effects of threat appraisals (Studies 1-3) and self-efficacy appraisals (Study 3) on coping responses. CONCLUSIONS: Cognitive defusion may be an important individual-difference predictor of coping behavior, adding to established theories of coping such as Lazarus and Folkman's (1987) transactional theory.

Contextual Positive Psychology: Policy Recommendations for Implementing Positive Psychology into Schools.

There has been a rapid growth in positive psychology, a research and intervention approach that focuses on promoting optimal functioning and well-being. Positive psychology interventions are now making their way into classrooms all over the world. However, positive psychology has been criticized for being decontextualized and coercive, and for putting an excessive emphasis on positive states, whilst failing to adequately consider negative experiences. Given this, how should policy be used to regulate and evaluate these interventions? We review evidence that suggests these criticisms may be valid, but only for those interventions that focus almost exclusively on changing the content of people's inner experience (e.g., make it more positive) and personality (improving character strength), and overemphasize the idea that inner experience causes action. We describe a contextualized form of positive psychology that not only deals with the criticisms, but also has clear policy implications for how to best implement and evaluate positive education programs so that they do not do more harm than good.
