The PsyCAP research team is made up of researchers in the Humanities and Social Sciences whose aim is to study and understand the behaviour of individuals in order to support the changes brought about by ecological, digital, energy and social transitions. It is interested, for example, in the acceptability of social and technological change, in co-construction with stakeholders through participatory approaches, and in the study of relationships between users and their environments, whether physical, digital or social. Positioned transversally, it addresses these issues in Cerema's ‘Environment and Risks’, ‘Building’, ‘Mobility’ and ‘Sea and Coast’ domains.

Challenges for society

Transitions, whatever their nature, are an inescapable social fact (Mauss, 1924) that cannot be overlooked due to their profound and ongoing impact on our societies. Indeed, these transitions (e.g., ecological, energy, digital, etc.) permeate and transform societies and organizations through new systems (e.g., autonomous vehicles), new imperatives (e.g., eco-friendly practices, energy conservation, prevention of emerging diseases), which often clash with individual and collective activities (Brangier et al., 2010). This is evident in the case of digital technology, which is revolutionizing every aspect of society (Schwab, 2017), particularly activities within organizations (Chahir et al., 2022). Yet, while digital tools are often considered highly innovative for facilitating organizational activities, their implementation frequently faces significant challenges (Garreau, 2019). For example, Jørgensen and colleagues (2014) show that only two out of ten managers consider their innovations successful within their organizations. Similarly, environmental projects positioned as solutions to climate change often face intense opposition, as demonstrated by the Atlas of Environmental Justice, launched by the European research project EJOLT (Environmental Justice Organisations, Liabilities and Trade, 2024). In 2024, the atlas recorded 4,181 cases of social conflicts related to environmental projects worldwide.

Taken as a whole, these transitions fall within the broader framework of social transition, where populations increasingly demand participation in decisions that affect them (CNDP, 2014). This is because such transitions require new adjustments, responding to calls from local authorities, deploying and/or implementing a project, technology, or service in a given territory. These spaces where stakeholders meet become fertile grounds for controversy, as they allow diverse and sometimes completely opposing positions to be expressed (e.g., attitudes toward a given technology). While controversies in these spaces can highlight the societal issues underlying projects (Limoges, 1993), they also put interpersonal relationships under significant strain. The reasons for this are manifold: the public has lost trust in decision-making spaces (Jacquet, 2017; Papadopoulos, 2013) and is often poorly informed about new technologies (e.g., Ha-Duong et al., 2009); decision-makers struggle to consider social dynamics in informing and raising awareness among stakeholders (e.g., Nadarajah, 2022, 2024); and project promoters tend to distance themselves from controversies, perceiving discussion spaces as particularly risky (Batellier, 2015; Pham & Torre, 2012).

In this context of urgency, the multiplication and combination of impacts—particularly those of climate change on ecosystems—make it increasingly difficult to predict the future of human societies (Robbins Schug et al., 2023). Consequently, current infrastructure, investments, and human activities must account for upcoming changes and adapt accordingly (ADEME, 2019).

Scientific approach

Faced with change, the question of behaviour appears to be a crucial one, whether it involves observing and understanding behaviour, modifying it or enabling adaptation by supporting individuals or structures. Behavioural sciences in general, and psychology in particular, are ideally placed to answer these questions, and are playing an increasingly important role.

So, in this context of transitions (i.e. ecological, digital, energy and social), we feel that several issues need to be highlighted: local issues - which will raise the question of social acceptability, support for change in local areas and citizen participation - global issues - which will raise questions about the perception of risks linked to technologies, air quality, road safety, etc. - and short- and long-term issues - which will raise questions, for example, about how to prevent and support future population movements linked to rising sea levels. 

Expected results

The scientific objectives of the PsyCAP team are to :

  • to understand and support the construction of individual and social acceptability in transitions (e.g. digital, ecological, energy, social, etc.) ;
  • studying and analysing human behaviour in order to understand and predict it, taking into account the ecological, digital, energy and social transitions that are changing behavioural dynamics and social practices;
  • producing knowledge and methodologies to support the changes brought about by technological, organisational and environmental change and innovation.

More specifically, the team studies: (1) the psychological dimensions (e.g. attitudes, norms, perceptions, representations, etc.) that enable behaviour to be predicted; (2) so-called subjective behaviour (i.e. behaviour that is self-reported by individuals) and (3) so-called objective behaviour (i.e. behaviour that can be observed), drawing on skills in cognitive science and social psychology to take a complementary approach to the notion of behaviour.
