The field of behaviour change suffers from significant fragmentation and poor reporting. Here, we describe two large-scale initiatives — the Human Behaviour Change Project and Science of Behavior Change programme — that aim to introduce complementary systematic and rigorous methods to advance the science of behaviour change.
Registered reports present a substantial departure from traditional publishing models with the goal of enhancing the transparency and credibility of the scientific literature. We map the evolving universe of registered reports to assess their growth, implementation and shortcomings at journals across scientific disciplines.
In 2017, Catalonia unilaterally declared independence from Spain. The independence push was not simply a bottom-up process wherein citizens increasingly demanded independence. Catalan political elites were more radical than voters and competitive outbidding to win hegemony in the pro-independence camp fuelled the independence push.
Although important steps have been taken to prevent publication of a disproportionate number of non-reproducible chance findings, null findings are usually still considered disappointing. There is every reason to change this perception, because lack of associations can teach us just as much as significant ones.
Some acts of human cooperation are not easily explained by traditional models of kinship or reciprocity. Fitness interdependence may provide a unifying conceptual framework, in which cooperation arises from the mutual dependence for survival or reproduction, as occurs among mates, risk-pooling partnerships and brothers-in-arms.
Many species face the problems of how, when and with whom to cooperate. Comparing responses across species can reveal the evolutionary trajectory of these decisions, including in humans. Using nearly identical economic game methods to compare species could identify the evolutionary constraints and catalysts to cooperation.
Knowledge that humans could trigger a regime shift in a vital natural system may help in identifying a goal for collective action, but it is unlikely to spur the degree of cooperation needed to avert a catastrophe. Substantial behaviour change can be achieved by manipulating the institutions that govern human action on the commons.
Through cooperation we are able to thrive, build societies, culture and technology. But history also reveals our potential for selfishness, spite and prejudice. Studying the neural processes that drive choice behaviour is essential to understand this paradox and develop means to curb greed and extend the limits of cooperation.
Video games are increasingly exposing young players to randomized in-game reward mechanisms, purchasable for real money — so-called loot boxes. Do loot boxes constitute a form of gambling?
The complex research, policy and industrial challenges of the twenty-first century require collaborative problem solving. Assessments suggest that, globally, many graduates lack necessary competencies. There is a pressing need, therefore, to improve and expand teaching of collaborative problem solving in our education systems.
The web is increasingly inhabited by the remains of its departed users, a phenomenon that has given rise to a burgeoning digital afterlife industry. This industry requires a framework for dealing with its ethical implications. The regulatory conventions guiding archaeological exhibitions could provide the basis for such a framework.
Many have argued that populism dominated the 2016 US presidential election. Textual analysis of electoral discourse in the United States, Greece and Venezuela suggests that the overall level of populism in the US election was in fact moderate. Bernie Sanders and Donald Trump engaged in populist discourse, but Trump lacked consistency.
In response to recommendations to redefine statistical significance to P ≤ 0.005, we propose that researchers should transparently report and justify all choices they make when designing a study, including the alpha level.
Early adolescence (age 10–14) is an important window of opportunity to address gender socialization as the basis for health and social justice. This Comment explains why this is the case and provides illustrative examples of existing evidence on strategies to promote gender equitable attitudes in young adolescents.
Why isn’t there a strong relation between income and happiness? Why do people avoid or seek self-confirmatory or even false information? Why do they play the lottery and buy insurance? Taking account of belief-based utility can enable economics to make sense of these and a multitude of other puzzling phenomena.
Identity formation is an important developmental process during adolescence, with several applied and public health implications. To prevent identity development from going astray, educational efforts, prevention programmes and policy initiatives are needed that help young people develop a healthy sense of identity.
