Cathodal HD-tDCS above the left dorsolateral prefrontal cortex increases environmentally sustainable decision-making.

Environmental sustainability is characterized by a conflict between short-term self-interest and longer-term collective interests. Self-control capacity has been proposed to be a crucial determinant of people's ability to overcome this conflict. Yet, causal evidence is lacking, and previous research is dominated by the use of self-report measures. Here, we modulated self-control capacity by applying inhibitory high-definition transcranial current stimulation (HD-tDCS) above the left dorsolateral prefrontal cortex (dlPFC) while participants engaged in an environmentally consequential decision-making task. The task includes conflicting and low conflicting trade-offs between short-term personal interests and long-term environmental benefits. Contrary to our preregistered expectation, inhibitory HD-tDCS above the left dlPFC, presumably by reducing self-control capacity, led to more, and not less, pro-environmental behavior in conflicting decisions. We speculate that in our exceptionally environmentally friendly sample, deviating from an environmentally sustainable default required self-control capacity, and that inhibiting the left dlPFC might have reduced participants' ability to do so.

Analysis of the influence of the COVID-19 outbreak on household solid waste management: An empirical study using PLS-SEM.

The global increase in solid waste pollution due to economic growth and population growth has led to severe ecological deterioration. This situation is exacerbated by the ongoing coronavirus disease (COVID-19) pandemic, which has significantly impacted consumer behavior and consumption habits. Proper management of solid waste has thus become critical in mitigating environmental degradation. In this study, we aim to examine the relationship between the outbreak of COVID-19, environmental attitudes (EATT), social norms (SN), environmental knowledge (EK), technological innovation (TI), and solid waste management (SWM) in Ecuadorian households during the pandemic. We collected data from 426 households in Ecuador using an online questionnaire and analyzed it using the Partial Least Squares Structural Equation Model method to test the hypotheses. Likewise, we validated the measurement and structural model. The results are novel about SWM, considering a developing country severely affected during the pandemic. Our findings suggest that COVID-19 has a negative impact on SWM, while EATT, SN, and TI have a positive influence on SWM. However, we found that EK does not significantly affect SWM.

Optimistic narrative future visions: a communication tool for promoting sustainable (plastic) behavior.

Plastic pollution is a pressing global issue, necessitating a focus on consumer behavior to curb this problem at its source. To effectively promote sustainable practices, communication strategies that employ future visions have gained attention. This study examines the effects of a narrative video intervention depicting an optimistic future vision concerning single-use plastic bag consumption in South Africa, compared to a representation of the prevailing status quo. Using a preregistered within-subject design, we assess the psychological and emotional responses to two scenarios of which one is illustrating adaptive behaviors toward reduced plastic bag usage, and the other showcasing current consumption patterns. Parametric analyses revealed a shift in emotional states, characterized by a greater experience of positive emotions and a reduced experience of negative emotions following the exposure to the optimistic future scenario video, as compared to the status quo video. Moreover, engagement with the optimistic future scenario was associated with higher levels of perceived behavioral control and behavioral intentions. No significant changes were found regarding sense of responsibility. These findings point to the potential of optimistic future visions to influence individuals at psychological and emotional levels. This renders optimistic future vision communication as an effective tool for sustainable behavior change, particularly in relation to the sustainable use of plastic shopping bags.

Honesty-humility predicts humanitarian prosocial behavior via social connectedness: A parallel mediation examining connectedness to community, nation, humanity, and nature.

Abundant psychological research demonstrates bivariate relationships between individual prosocial propensity, intrinsic connectedness to various social domains, and the enactment of prosocial behavior. More recently, "connectedness" has been positioned as a necessary domain-specific motivator for enacting prosocial propensity in relevant domains of concern. Our study offers novel contributions to this theory by examining the role of connectedness in driving prosocial behavior within a humanitarian domain in which behavior is enacted in the interest of the global community. Additionally, our research uniquely considers connectedness to multiple social domains concurrently, in order to disentangle any covariance that may be impacting research findings. A parallel mediation model with four mediators (connectedness to community, nation, humanity, and nature) was applied to better understand the effect of prosocial propensity (honesty-humility) on humanitarian prosocial behavior. The cross-sectional survey was completed by 715 Australian adults, and support was found for mediation via each of the mediators. Specifically, connectedness to community, to humanity, and to nature each positively affected the relationship between prosocial propensity and prosocial behavior, with the largest effect via connectedness to humanity. Contrastingly, connectedness to nation negatively mediated this relationship, despite being positively correlated with these constructs. These findings highlight the individual difference underpinnings of humanitarian prosocial behaviors and the role of connection to relevant domains in behavior actualization. Fostering connectedness to humanity remains desirable to promote global prosocial outcomes, with future research needed on the interplay between these related levels of connectedness and between connectedness to one's nation and global humanitarian engagement.

Cognitive bias and how to improve sustainable decision making.

The rapid advances of science and technology have provided a large part of the world with all conceivable needs and comfort. However, this welfare comes with serious threats to the planet and many of its inhabitants. An enormous amount of scientific evidence points at global warming, mass destruction of bio-diversity, scarce resources, health risks, and pollution all over the world. These facts are generally acknowledged nowadays, not only by scientists, but also by the majority of politicians and citizens. Nevertheless, this understanding has caused insufficient changes in our decision making and behavior to preserve our natural resources and to prevent upcoming (natural) disasters. In the present study, we try to explain how systematic tendencies or distortions in human judgment and decision-making, known as "cognitive biases," contribute to this situation. A large body of literature shows how cognitive biases affect the outcome of our deliberations. In natural and primordial situations, they may lead to quick, practical, and satisfying decisions, but these decisions may be poor and risky in a broad range of modern, complex, and long-term challenges, like climate change or pandemic prevention. We first briefly present the social-psychological characteristics that are inherent to (or typical for) most sustainability issues. These are: experiential vagueness, long-term effects, complexity and uncertainty, threat of the status quo, threat of social status, personal vs. community interest, and group pressure. For each of these characteristics, we describe how this relates to cognitive biases, from a neuro-evolutionary point of view, and how these evolved biases may affect sustainable choices or behaviors of people. Finally, based on this knowledge, we describe influence techniques (interventions, nudges, incentives) to mitigate or capitalize on these biases in order to foster more sustainable choices and behaviors.

Understanding the Environmentally Sustainable Behavior of Chinese University Students as Tourists: An Integrative Framework.

The purpose of this study is to develop a theoretical framework by integrating the value-belief-norm (VBN) theory with environmental awareness in measuring Chinese university students' environmentally sustainable behavior toward tourism destinations. University students tend to engage in sustainability efforts since their values and beliefs are still being formed. The participants were 301 university students from a university in eastern China. The empirical findings demonstrate that: (1) environmental awareness has positive influences on biospheric value, altruistic value and egoistic value; (2) biospheric value positively predicts the new ecological paradigm (NEP), whereas altruistic and egoistic values do not; (3) the NEP, awareness of consequence and personal norms play an important mediating role. Results indicate that extended VBN can explain students' environmentally sustainable behavior. This research supports the growth of sustainable tourism and has a number of practical implications for universities and the relevant environmental departments to promote university students' involvement in sustainable tourism.

The relationship between the aspects of connectedness and sustainable consumption.

Internal transformative qualities are essential contributing factors to sustainable behavior. Besides awareness, insight, purpose, and agency, connectedness is one of those inner qualities. In this study, we investigated the relationship between connectedness to oneself (self-love), towards the environment (connectedness to nature), towards other human beings (pro-socialness), and sustainable behavior towards clothes and food. One hundred thirty-nine mostly students participated. The results showed that self-love, connectedness to nature, and pro-socialness correlate. Sustainability behavior towards food was predicted by pro-socialness, the choice of diet, and environmental and ethical reasons for nutrition. Sustainable behavior towards clothes was predicted by connectedness to nature. This study hints that the factors of inner transformative qualities and the type of sustainable behavior must be investigated differently. It strengthens the multi-facet dimensions of sustainable behavior.

Trends in Food Preferences and Sustainable Behavior during the COVID-19 Lockdown: Evidence from Spanish Consumers.

The COVID-19 pandemic poses a threat to global food security, and it changes consumers' food buying and consumption behavior. This research not only investigates trends in Spanish consumers' general food shopping and consumption habits during the lockdown, but also investigates these trends from the perspective of sustainable purchasing. Specifically, total food consumption (C), food expenditure (E), and purchase of food with sustainable attributes (S) were measured. Data were collected from a semi-structured questionnaire which was distributed online among 1203 participants. The logit models showed that gender, age, employment status, and consumers' experiences were associated with total food consumption and expenditure during the lockdown. In addition, consumers' risk perceptions, shopping places, trust level in information sources, and risk preference were highly essential factors influencing consumers' preferences and sustainable behavior. Consumers' objective knowledge regarding COVID-19 was related to expenditure. Furthermore, family structure only affected expenditure, while income and place of residence influenced food consumption. Mood was associated with expenditure and the purchase of sustainable food. Household size affected purchasing behavior towards food with sustainable attributes. This research provides references for stakeholders that help them to adapt to the new COVID-19 situation.

El futuro trascendental como determinante de las conductas sustentables y la percepción de felicidad / Transcendental future as a determinant of sustainable behavior and the perception of happiness

Resumen La perspectiva temporal es una variable psicológica que se ha asociado con múltiples comportamientos, entre ellos la conducta sustentable (CS). Son escasos los estudios sobre la relación entre la orientación temporal denominada futuro trascendental y la CS. Objetivo: estimar las relaciones entre dos perspectivas temporales (orientación al futuro y orientación al futuro trascendental) y la conducta sustentable; y su asociación, con el autocuidado y la felicidad. Metodología: estudio correlacional, con un diseño no experimental, transeccional. Participaron 209 personas de una ciudad al noroeste de México, con una edad promedio de 30.33 años, quienes respondieron a un instrumento que constó de ocho escalas Likert que evaluaron perspectiva de futuro, perspectiva temporal de futuro trascendental, conducta proecológica, altruismo, frugalidad, equidad, comportamientos de autocuidado y felicidad subjetiva. Las interrelaciones entre las variables se estimaron mediante un modelo de ecuaciones estructurales. Resultados: las orientaciones temporales al futuro y al futuro trascendental influyen en las conductas sustentables (conducta proecológica, altruismo, frugalidad, equidad), que, a su vez, impactan en la felicidad y el autocuidado de las personas. Conclusiones: Estos hallazgos aportan información valiosa que ayuda a elucidar las características que posee un individuo que orienta su conducta a los ideales de la sostenibilidad.

Abstract Time perspective is a psychological variable that has been associated it with multiple behaviors, including sustainable behaviors. Research on transcendental future perspective is scarce, among the studies on temporal perspective and sustainable behavior, none were found on the relationship between transcendental future and SC. Objective: this research was aimed at assessing the relationship between two-time perspectives (future orientation, transcendent future orientation) and sustainable behavior, and its association with self-care and happiness. Method: a correlational study was developed, with a non-experimental, transactional design. Two hundred nine people from a northwestern city in Mexico participated, with an average age of 30.33 years, who responded to an instrument that consisted of eight Likert scales that evaluated future perspective, transcendental future temporal perspective, pro-ecological behavior, altruism, frugality, equity, self-care behaviors, and subjective happiness. Results: the results were processed within a structural equation model, where it is emphasized that temporal orientations to the future and to the transcendental future influence sustainable behaviors (pro-ecological behavior, altruism, frugality, equity), which, in turn, impact on the happiness and self-care of people. Conclusion: these findings provide valuable information that helps elucidate the characteristics of an individual who guides his behavior to sustainability ideals.

Diseño de macro y metacontingencia para la promoción del comportamiento proambiental y urbano responsable / Macro and meta-contingency design for the promotion of a responsible pro-environmental and urban behavior

Resumen El objetivo de este trabajo teórico es introducir los conceptos de macrocontingencia y metacontingencia en el campo de la psicología ambiental y su papel en la promoción de acciones colectivas en pro del medio ambiente natural y construido. Se proponen este tipo de contingencias para el diseño de prácticas culturales y programas sociales que ayuden a resolver problemas ambientales como el cambio climático, la extinción de especies, la contaminación del agua, la deforestación, las migraciones, el vandalismo, etc., e incentivar comportamientos urbanos responsables como el uso de la bicicleta y del transporte urbano, el reciclaje, etc. Aunque las acciones de cada persona pueden contribuir a las soluciones, el planteamiento del presente manuscrito se centra en el efecto acumulativo y las acciones entrelazadas de los individuos que producen un resultado eficaz para el bienestar de muchas personas y del medio ambiente. La conducta guiada por reglas se presenta como el mecanismo de aprendizaje para introducir las macrocontingencias y metacontingencias en la comunidad. A partir del pragmatismo como visión paradigmática, se discute la efectividad de las macrocontingencias y metacontingencias para explicar los procesos culturales en la promoción de acciones efectivas para el medio ambiente.

Abstract This article aims to introduce the concepts of macrocontingency and metacontingency into environmental psychology to promote collective actions in pro of the natural and urban environment. The design of cultural practices oriented to achieve the goal requires the definition of contingencies that promote social process to solve environmental problems such as: climate change, species extinction, water contamination, deforestation, migration, vandalism, etc, and to encourage responsible urban behaviors such as the use of bicycles, urban transport, recycling, among others. Although each person´s actions may contribute to the solutions, the approach of this theoretical paper is focused on the cumulative effect and the interconnected actions of people that produce an effective outcome for the well-being of many and the environment. Rule - driven behavior is showed as the learning mechanism to introduce the macrocontingencies and metacontingencies in the community. Based on pragmatism as a paradigmatic view, it is discussed the effectiveness of macrocontingencies and metacontingencies in explaining cultural processes to promote effective actions for the environment.

It's more than climate change and active transport-physical activity's role in sustainable behavior.

Considering the interdependence of human's and nature's health within the planetary health concept, we evaluated how physical activity (PA) can be conceptualized as sustainable behavior (SuB) and how PA relates to other types of SuBs within the United Nations' sustainable development goal (SDG) framework. Regarding social SDGs, PA contributes to improving malnutrition (SDG 2), health behaviors (SDG 3), education (SDG 4), reducing inequalities (SDG 10), sustainable cities (SDG 12), and peace (SDG 16). For ecological SDGs, PA contributes to sustainable consumption (SDG 11) and combating climate change (SDG 13). Therefore, PA is more than a health behavior, it contributes to planetary health and sustainable development. However, caution is warranted as PA also has the potential to contribute and reinforce unsustainability. Thus, PA as a SuB requires an own research agenda, investigating (a) PA as social and ecological SuB, (b) sustainable PA promotion, (c) sustainable PA measurement, (d) common underlying constructs of PA and SuB, and (e) technology's role to assess and promote PA and SuB.

Connectedness to Nature: Its Impact on Sustainable Behaviors and Happiness in Children.

Given the environmental problems humanity is currently facing, and considering that the future of the planet lies in the hands of children and their actions, research on the determinants of sustainable behaviors in children has become more relevant; nonetheless, studies on this topic focusing on children are scarce. Previous research on adults suggests, in an isolated manner, the relationship between connectedness to nature, the development of behaviors in favor of the environment, and positive results derived from them, such as happiness and well-being. In the present research, connectedness to nature was considered as a determinant of sustainable behaviors, and happiness was considered as a positive consequence of the latter. This research aimed to demonstrate the relationship between these variables in children. Two hundred and ninety-six children with an average age of 10.42 years old participated in the study, in which they responded to a research instrument that measured connectedness to nature, sustainable behaviors (pro-ecological behavior, frugality, altruism, and equity), and happiness. To analyze the relationships between these variables, a model of structural equations was specified and tested. The results revealed a significant relationship between connectedness to nature and sustainable behaviors, which, in turn, impact happiness. This suggests that children who perceive themselves as more connected to nature tend to perform more sustainable behaviors; also, the more pro-ecological, frugal, altruistic, and equitable the children are, the greater their perceived happiness will be. The implications for studying and promoting sustainable behaviors are discussed within the framework of positive psychology.

Associations between pro-environmental behaviour and neighbourhood nature, nature visit frequency and nature appreciation: Evidence from a nationally representative survey in England.

Progress on changing human behaviour to meet the challenges of regional and global sustainability has been slow. Building on theory as well as small-scale survey and experimental evidence that exposure to nature may be associated with greater pro-environmentalism, the aim of the current study was to quantify relationships between exposure to nature (operationalised as neighbourhood greenspace, coastal proximity, and recreational nature visits) as well as appreciation of the natural world, and self-reported pro-environmental behaviour for the adult population of England. Using data from a nationally representative sample (N = 24,204), and controlling for potential confounders, a structural equation model was used to estimate relationships. Indirect effects of neighbourhood exposures via nature visits and nature appreciation were accounted for. We found positive relationships between both recreational nature visits and nature appreciation and pro-environmental behaviour across both the whole sample and key socio-demographic groups. The more individuals visited nature for recreation and the more they appreciated the natural world, the more pro-environmental behaviour they reported. Although rural and coastal dwellers tended to also be more pro-environmental on average, patterns were complex, potentially reflecting situational constraints and opportunities. Importantly, positive associations between pro-environmental behaviours and high neighbourhood greenspace and coastal proximity were present for both high and low socio-economic status households. Improving access to, and contact with, nature, e.g., through better urban planning, may be one approach for meeting sustainability targets.

Reading a short story changes children's sustainable behavior in a resource dilemma.

Fostering sustainable behavior in children and adolescents should be a central aim of today's education. Even though the interplay of factors affecting sustainable behavior is complex, simple interventions can be effective too. In the current study, 10-year-olds (N = 132) were read a short story about two foresters who collectively used a forest to gain timber, facing a resource dilemma that involved striving for maximizing their individual profit while sustaining the forest. In the story, the foresters solved the dilemma in favor of the resource, thereby serving as positive role models. Children in the control condition were read a short informative story on urban gardening that did not include a dilemma or any moral cues. Before and after the intervention, children played a fishing conflict game to assess their sustainable behavior. Children who were presented with the positive role models played the game after the intervention more sustainably than before the intervention. Children in the control condition, in contrast, played it even less sustainably after the intervention. The results suggest that a short intervention might affect children's sustainable behavior.

Paradojas del comportamiento proambiental de los estudiantes universitarios en diferentes disciplinas académicas / Paradoxes of the environmental behavior of university students in different academic disciplines

Resumen El objetivo del presente estudio fue establecer las características del comportamiento proambiental de los estudiantes universitarios colombianos, esto es, identificar las actitudes, creencias, valoraciones, prácticas y conocimientos ambientales de estudiantes colombianos de diferentes carreras universitarias. Para ello se realizó un estudio descriptivo-correlacional de corte transversal con una muestra de 1503 estudiantes de diferentes carreras universitarias en cinco ciudades colombianas, con una probabilidad de incidencia de .5, 95 % de confianza y un error del 2.5 %. Los participantes fueron seleccionados aleatoriamente al interior de cada universidad y seles aplicaron el Inventario de Comportamiento Proambiental (ICP) y el Test de Conocimiento Ambiental (TCA), este último desarrollado específicamente para propósitos de la presente investigación. Se encontró que los estudiantes encuestados poseen actitudes y creencias ambientales positivas en la mayoría de las dimensiones. El nivel de conocimiento ambiental de los estudiantes en las cinco ciudades seleccionadas es bajo. Si bien no se observaron diferencias significativas entre las carreras respecto a las creencias, valoraciones, acciones y conocimientos ambientales, paradójicamente los estudiantes de ciencias ambientales ocuparon lugares inferiores a los que estudian ciencias económicas y administrativas. Se puede concluir que existen diferencias según la ciudad en las creencias, valoración, conocimiento y acciones ambientales de los estudiantes encuestados. El reporte de acciones ambientales presenta un perfil controversial pues al mismo tiempo las personas realizan comportamientos proambientales y antiambientales. Las instituciones universitarias y el gobierno tienen el desafío de lograr que la educación ambiental muestre los resultados esperados para el cumplimiento de las metas ambientales del país y del mundo.

Abstract The objective of the present study was to establish the characteristics of the pro environmental behavior of Colombian university students; that is, to identify the attitudes, beliefs, valuations, practices and environmental knowledge of Colombian students from different university careers. For this purpose, a cross-sectional descriptive-correlational study was carried out with a sample of 1503 students from different university careers in five Colombian cities, with an incidence probability of .5, 95 % confidence and an error of 2.5 %. The participants were randomly selected within each university and the questionnaires applied were the Pro environmental Behaviour Inventory (ICP) and the Environmental Knowledge Test (TCA); the latter was developed specifically for the purposes of this research. The students surveyed were found to have positive environmental attitudes and beliefs in most dimensions. The level of environmental awareness of students in the five selected cities is low. Although no significant differences were observed between the careers with respect to beliefs, valuations, actions and environmental knowledge, paradoxically the students of environmental sciences occupied inferior places to those who study economic and administrative sciences. Thus, in the analysis of specific items it was evidenced that the students of environmental sciences develop diverse anti environmental actions, in a similar way to the behavior patterns of the students of the other researched careers. With respect to the region, the results show that it is possible to conclude that there are differences according to the city with respect to the beliefs, valuation, knowledge and environmental actions of the students surveyed. Among the findings it is worth highlighting the results of Bucaramanga in terms of the report of environmental actions and the highest average in the TCA observed in that city. Similarly, Cali stands out along with Bucaramanga in its results, while Medellín obtained the lowest scores in environmental knowledge. Finally, in the report on environmental actions in university students, contradictory results are observed, given that it presents a controversial profile because people perform pro-environmental and anti-environmental behaviors at the same time, with positive environmental attitudes and beliefs in accordance with these attitudes. Regarding the knowledge about the environment, in the descriptive results the average of the test was 12 points, which means that the students failed the test. The multivariate analysis showed that the theoretical model on which the construction of the ICP was based and the instruments from which items were selected for its conformation, apparently has great predictive power with respect to the verbal report of environmental actions; however, the TCA, a test constructed specifically for this research, would covariate with almost all the factors of the ICP but does not predict causally the actions reported by the students. In general, this study shows that university institutions and the Colombian government have the challenge of ensuring that environmental education achieves the expected results for the fulfillment of both the country and the world's environmental goals. The results also demonstrates the need to articulate policies, actions and regulations to improve the quality of environmental education in universities, as well as to implement citizen behavior programs that promote responsible consumption, given that knowledge does not correlate with effective actions in terms of public services, green brands and solid urban waste management, among other areas.

Beachgoer participation in prevention of marine litter: Using design for behavior change.

Much marine litter comes from land-based sources, with a significant amount coming from activities on bathing beaches. Thus, the overall focus of this exploratory research is to identify elements important for the design of beach infrastructure (i.e., trash cans (TCs)) to reduce littering behaviors. We base our investigation on principles of a relatively new approach, called Design for Sustainable Behavior. In doing so, we consider design for two user groups: bathing beachgoers and beach managers. We examined these users' perceptions of beach TCs through the use of an on-line survey of beachgoers, in-depth interviews with Israeli beach managers, a survey of international Blue Flag beach managers and a design 'ideation' workshop. Most importantly, we found that there is interest on the part of beach managers and other stakeholders in applying design principles to improve TCs. The findings of this study have implications for further interdisciplinary - and multidisciplinary - research on this topic.

Factors that affect primary school children's sustainable behavior in a resource dilemma.

Acting ecologically sustainably and not exhausting natural resources is becoming more and more important. Sustainable behavior can be investigated within the conceptual frame of resource dilemmas, in which users share a common, slowly regenerating resource. A conflict emerges between maximizing one's own profit and maintaining the resource for all users. Although many studies have investigated adults' behavior in resource dilemmas, barely anything is known about how children deal with such situations and which factors affect their behavior. Due to their still developing cognitive and social skills as well as their self-control, they might act differently than adults. In the current study, 114 children aged 6 to 11 years played a fishing conflict game. We manipulated (a) whether children played alone or in groups, (b) whether withdrawal was limited or not, and (c) whether children were allowed to communicate within the groups or not. In addition, children's individual characteristics that were expected to be related to their sustainable behavior were assessed (i.e., delay of gratification, fairness concept, relatedness to nature, math grade, and age). Children's success in maintaining the resource strongly depended on the game context. Similar to adults, children acted more ecologically sustainably when they played alone, when the withdrawal was limited, and when communication was allowed. In addition, older children acted more sustainably than younger children. The results are discussed in the light of findings with adults and with regard to potential interventions that aim at enhancing children's sustainable behavior.

Navigating cognition biases in the search of sustainability.

We provide a conceptual review of the available knowledge on the role of human cognition biases for sustainability and sustainable behavior. Human cognition biases are defined as any deviation in decision making from the standard framework of rational choice. We distinguish between biases in individual decision making and biases in group decision making, and highlight the relevance of each for sustainable behavior. We find that while both categories may contribute to unsustainable behavior, human cognition biases in group settings might be central to understanding many of the current sustainability issues. Moreover, we argue that the effects of group-related biases may outweigh those on the individual level in driving unsustainable behavior, and that biases that have been discussed under various labels in the literature can be interpreted as manifestations of human cognition biases in group settings.
