Households waste huge amounts of food, which leads to considerable financial costs for individuals and substantial contributions to CO2 emissions. But this is a complex problem to address. In this Comment, Tapper and colleagues discuss how behavioural and systems science can help to provide solutions.

Corporate waste strategies are limited, and recycling is not enough to solve the global waste crisis. This Comment highlights the urgent need for businesses to adopt zero-waste principles by redesigning products and systems and discarding greenwashing. To drive this change, corporate governance must be inclusive and incentivize reduction.

Human behaviour has been identified as a key dynamic in sustainable waste management and circular economy research. Drawing on recent behaviour publications from both fields, this Perspective highlights three issues relating to how they frame people. First, reference to ‘consumers’ in circular economy research contrasts with ‘people’ in some sustainable waste management papers. This represents an artificial separation of approaches to activities that are interwoven; furthermore, it implicitly defines a business agenda for the circular economy. Second, research into behaviour needs a broader methodological approach to identify variable needs and address underlying contextual and structural issues. Third, attention is needed to ongoing inequalities within and between countries that limit the effectiveness of circular economy implementation. Future research in these fields should prioritize human-centred approaches, including critical realism and qualitative methods, to uncover the socio-political constraints on behaviour and guide sustainability strategies that address the needs of people. This Perspective urges a shift away from viewing people as ‘consumers’ in circular economy and sustainable waste management research, highlighting a need for human-centred methods to better understand behaviour and drive meaningful change.

Economist George Baffour Awuah discusses how a quiet revolution is helping to turn a waste crisis to economic opportunity in the Global South. But for scale, a supportive ecosystem is required.

Human languages show astonishing variety, yet their diversity is constrained by recurring patterns. Linguists have long argued over the extent and causes of these grammatical ‘universals’. Using Grambank—a comprehensive database of grammatical features across the world’s languages—we tested 191 proposed universals with Bayesian analyses that account for both genealogical descent and geographical proximity. We find statistical support for about a third of the proposed linguistic universals. The majority of these concern word order and hierarchical universals: two types that have featured prominently in earlier work. Evolutionary analyses show that languages tend to change in ways that converge on these preferred patterns. This suggests that, despite the vast design space of possible grammars, languages do not evolve entirely at random. Shared cognitive and communicative pressures repeatedly push languages towards similar solutions. Despite their great diversity, human languages are shaped by recurring grammatical universals. Verkerk et al. show that about one-third of the proposed universals hold cross-linguistically through analyses of the Grambank database.

Historical efforts to deinstitutionalize those experiencing mental illness in the USA have inadvertently positioned police officers as the typical first responders to emergency calls involving mental health crises and empower them to initiate involuntary psychiatric detentions. Although potentially lifesaving, such detentions are controversial and costly, and they may be medically inappropriate for some of those detained. Here we present evidence from two quasi-experimental designs on the causal effects of a ‘co-responder’ programme that pairs mental health professionals with police officers as first responders on qualified emergency calls. The results indicate that a co-responder programme reduced the frequency of involuntary psychiatric detentions by 16.5% (that is, 370 fewer detentions over 2 years; b = −0.180, 95% confidence interval −0.325 to −0.034) but had no detectable effect on programme-related calls for service, criminal offences or arrests. Complementary results based on incident-level data suggest this reduction reflects both a co-responder’s influence on the disposition of an individual incident and a reduction in future mental health emergencies. In a quasi-experimental analysis of emergency calls in California communities, Dee and Pyne find that having mental health first responders accompany police on qualified calls reduces the number of individuals placed in involuntary psychiatric detentions.
