Introduction
Social Psychologist (Associate Professor - Maître de conférences HDR) at Rennes 2 University. My research topics are focused on collective beliefs and social thought. I am particularly interested in behaviours and conduct known as irrational through conspiracy theories and rumours, collective memory and social representations, collective fears and social identity, common sense and lay knowledge. http://sylvaindelouvee.info/

Conspiracy theories and rumors, as forms manifesting “social thought” (Rouquette, 1973), share processes and functions. The few studies dealing specifically with the question of belief in rumors questioned the link between adhesion and transmission (Allport & Lepkin 1943; Rosnow, 1991; Guerin & Miyazaki, 2006). The aim here will be to question the...

Despite the scientific consensus about the anthropogenic nature of climate change, there are still obstacles hindering society from acknowledging the severity of the situation. Notably, previous research suggests that climate change threats can cause people to display ethnocentric reaction to preserve the ingroup’s interests. In this research, we i...

The identification-prejudice link describes the defensive stance toward immigrants held by strong national identifiers. Recent research refined this relationship by suggesting that defensive national identification (operationalized through national narcissism), but not secure national identification, was associated with prejudice. While previous re...

Sujet d'actualité incontournable, les « théories du complot » font l'objet de nombre d'analyses et de commentaires. Ces récits alternatifs aux opinions communément admises et aux explications fournies par les autorités postulent l'existence de forces malfaisantes responsables de machinations secrètement élaborées : des complots. Mais pourquoi et co...

At the beginning of 2020, COVID-19 became a global problem. Despite all the efforts to emphasize the relevance of preventive measures, not everyone adhered to them. Thus, learning more about the characteristics determining attitudinal and behavioral responses to the pandemic is crucial to improving future interventions. In this study, we applied ma...

Research on conspiracy theories tends to frame conspiracy believers as isolated individuals falling prey to irrational beliefs caused by a variety of pathological traits and cognitive shortcomings. But evidence is accumulating that conspiracy theory believers are also linked together in social movements capable of effectively coordinated collective...

A large body of research has found mixed evidence that people who are quick to dismiss randomness as a potential cause for an event are also more likely to believe conspiracy theories. To clarify the relationship between randomness dismissal and conspiracist ideation, we conducted a high-powered preregistered replication of an influential study in...

Despite the proven effectiveness of COVID-19 preventive measures, these remain inoperative if individuals do not adopt them. We sought out to investigate the effectiveness of a novel type of intervention to foster compliance with COVID-19 preventive measures. Drawing upon the model of action phases and evidence linking social motives to compliance...

People differ in their general tendency to endorse conspiracy theories (that is, conspiracy mentality). Previous research yielded inconsistent findings on the relationship between conspiracy mentality and political orientation, showing a greater conspiracy mentality either among the political right (a linear relation) or amongst both the left and r...

Since the 1970s, there has been a growing interest in how individuals appropriate scientific knowledge, which has recently been reinforced by societal issues such as vaccine releases and skepticism about global warming. Faced with the health and social consequences of the mistrust of scientific knowledge, there is an urgent need for tools to measur...

We recruited 1118 students in England, Greece and France, trained to become middle school...

Background: Social distancing and mass quarantines were implemented worldwide in response to the current COVID-19 pandemic. Prior research has shown that such measures bear negative consequences for population mental health and well-being.

In the midst of the COVID-19 pandemic (between 26 March and 2 April 2020), we analysed ( n = 1144) the social representations of the coronavirus and the differentiated perceptions according to the origins attributed to the appearance of the virus (Human vs Non-Human and Intentional vs Unintentional) in a French population.

The present study was carried out in December, 2018 and aimed at exploring the “Yellow Vests” movement when the revolts were in full swing. It involved 260 French participants (Mage = 42.9 years, SDage 14.6, Min = 18 to Max = 88). Results confirmed our hypotheses. The people who most identified with the “Yellow Vests” are those who perceive the sys...

Critical thinking is of paramount importance in our society. People regularly assume that critical thinking is a way to reduce conspiracy belief, although the relationship between critical thinking and conspiracy belief has never been tested. We conducted two studies (Study 1, N = 86; Study 2, N = 252), in which we found that critical thinking abil...

Many conspiracy theories appeared along with the Zika outbreak. While the virus is still circulating, motives underlying Zika conspiracy beliefs remain underexplored. National narcissism has been shown to be a robust social motive predicting conspiracy beliefs about other public health crises. This relationship has been interpreted as conspiracy be...

A few taxonomies have been proposed to categorize the cues consumers use to assess the quality of a given product. However, these taxonomies do not take into account the possible hierarchy that may exist among these cues. Through three studies we tested a taxonomy based on the structural approach to social representations. This framework proposes a...

The ongoing COVID-19 pandemic is a devastating global health crisis. Without a vaccine or effective medication, the best hope for mitigating virus transmission is collective behavior change and support for public health interventions (e.g., physical distancing, physical hygiene, and endorsement of health policies).

Research on conspiracy theories has long debated about the definition of conspiracy theories, and especially the demarcation between real conspiracies (i.e., that were proven to have occurred) and conspiracy theories (which are at best hypothetical). The existence of real conspiracies is often invoked as an argument to consider some conspiracy theo...

Des philosophes et des chercheurs tentent...

In this article we use a social representational perspective on a large sample of European students to consider the interplay between pacifist attitudes and representations of World War I (WWI). WWI gave rise to pacifist movements across the globe. Across 10 European countries (N = 1,347 undergraduate students), we invited participants to report th...

Teleological thinking — the attribution of purpose and a final cause to natural events and entities — has long been identified as a cognitive hindrance to the acceptance of evolution, yet its association to beliefs other than creationism has not been investigated. Here, we show that conspiracism — the proneness to explain socio-historical events in...

Les théories du complot et les rumeurs, comme formes de manifestation de la pensée sociale (Rouquette, 1973), partagent processus et fonctions. Le peu d’études s’intéressant spécifiquement à la question des croyances dans les rumeurs questionnait le lien entre adhésion et transmission (Prasad, 1935 ; Allport et Lepkin, 1945 ; Rosnow, 1991 ; Guerin...

La peur collective n’est pas simplement associée à des craintes de « haut niveau » telles que les attaques terroristes, les catastrophes naturelles, le sida ou les épidémies. Elle recouvre aussi ce que plusieurs travaux académiques ont appelé les « peurs tranquilles » de la vie de tous les jours. Ce polymorphisme de la notion de peur explique sans...
