Introduction
I want to understand what works to helps us lead healthier and more sustainable lives. My research program focuses on the effectiveness of behavioral interventions to promote healthy and sustainable living - eg. how to best promote energy savings, reduce food waste, increase cancer screening or blood donation. I translate behavioral science into practice to tackle these critical challenges, and to respond to calls for better informed policies. I use a variety of methodological tools including (1) Lab studies testing small-scale psychologically-driven interventions; (2) Large field experiments testing how to scale-up behavioral interventions in natural settings; and (3) Evidence-based policy evaluation, based on meta-analyses of randomized controlled trials and quasi-experiments.

Article
Full-text available
This paper examines whether compliance with COVID-19 mitigation measures is motivated by wanting to save lives or save the economy (or both), and which implications this carries to fight the pandemic. National representative samples were collected from 24 countries (N = 25,435). The main predictors were (1) perceived risk to contract coronavirus, (...

The COVID-19 pandemic presented a unique challenge to social and behavioral science. Until very recently, and for almost a year, behavioral (non-pharmaceutical) measures were the only tools available to fight the pandemic: wearing masks, frequent handwashing, and social distancing from crowds and private gatherings. Despite the life-saving potentia...

No consensus exists regarding which are the most effective mechanisms to promote household action on climate change. We present a meta-analysis of randomised controlled trials comprising 3,092,678 observations, which estimates the effects of behavioural interventions holding other factors constant. Here we show that behavioural interventions promot...
Article
We present a simple behavioral strategy based on Prospect Theory that maximizes the impact of financial incentives with no additional cost. We show how the partition of a single incentive into two smaller incentives of equivalent total amount produces substantial behavioral changes, here demonstrated in the context of colorectal cancer screening. I...
Article
This research examines how the relationship between passion for an ideology and violent activism is magnified by the personal (vs. collective) loss of significance. In Study 1 (N = 238), the relationship between obsessive (but not harmonious) passion for the Republican Party and violent activism was moderated by personal (but not collective) loss o...
Article
Full-text available
The present paper examines longitudinally how subjective perceptions about COVID-19, one’s community, and the government predict adherence to public health measures to reduce the spread of the virus. Using an international survey ( N = 3040), we test how infection risk perception, trust in the governmental response and communications about COVID-19...
Article
Food waste at the consumer level poses a global challenge for natural resources management and contributes to climate change. However, there is limited evidence regarding the best messaging strategies to fight household food waste. Here we experimentally test several food waste messages, aiming to identify the most effective strategies to promote i...
Article
Full-text available
Before vaccines for COVID-19 became available, a set of infection prevention behaviors constituted the primary means to mitigate the virus spread. Our study aimed to identify important predictors of this set of behaviors. Whereas social and health psychological theories suggest a limited set of predictors, machine learning analyses can identify cor...
Article
Full-text available
Anxiety associated with the COVID-19 pandemic and home confinement has been associated with adverse health behaviors, such as unhealthy eating, smoking, and drinking. However, most studies have been limited by regional sampling, which precludes the examination of behavioral consequences associated with the pandemic at a global level. Further, few s...
Article
Objective: This research examines the interface between ideological passion and the dark tetrad personality traits to predict violent (vs. peaceful) political activism. Meta-analytic research shows that ideological obsessive passion (OP) is one of the strongest psychological factors associated with violent activism. Here, we examine whether this re...
Article
Understanding the determinants of COVID-19 vaccine uptake is important to inform policy decisions and plan vaccination campaigns. The aims of this research were to: (1) explore the individual- and country-level determinants of intentions to be vaccinated against SARS-CoV-2, and (2) examine worldwide variation in vaccination intentions. This cross-s...
Article
Understanding how individual beliefs and societal values influence support for measures to prevent SARS-CoV-2 transmission is vital to developing and implementing effective prevention policies. Using both Just World Theory and Cultural Dimensions Theory, the present study considered how individual-level justice beliefs and country-level social valu...
Article
Full-text available
Tightening social norms is thought to be adaptive for dealing with collective threat yet it may have negative consequences for increasing prejudice. The present research investigated the role of desire for cultural tightness, triggered by the COVID-19 pandemic, in increasing negative attitudes towards immigrants. We used participant-level data from...
Article
During the initial phase of the COVID-19 pandemic, U.S. conservative politicians and the media downplayed the risk of both contracting COVID-19 and the effectiveness of recommended health behaviors. Health behavior theories suggest perceived vulnerability to a health threat and perceived effectiveness of recommended health-protective behaviors dete...

Article
Full-text available
The coronavirus disease 2019 (COVID-19) pandemic has caused a global health crisis. Consequently, many countries have adopted restrictive measures that caused a substantial change in society. Within this framework, it is reasonable to suppose that a sentiment of societal discontent, defined as generalized concern about the precarious state of socie...
Article
Full-text available
Attachment theory is an ethological approach to the development of durable, affective ties between humans. We propose that secure attachment is crucial for understanding climate change mitigation, because the latter is inherently a communal phenomenon resulting from joint action and requiring collective behavioral change. Here, we show that priming...
Article
Full-text available
The current research examined the role of values in guiding people’s responses to COVID-19. Results from an international study involving 115 countries (N = 61,490) suggest that health and economic threats of COVID-19 evoke different values, with implications for controlling and coping with the pandemic. Specifically, health threats evoked prioriti...
Article
We examine how social contacts and feelings of solidarity shape experiences of loneliness during the COVID-19 lockdown in early 2020. From the PsyCorona database, we obtained longitudinal data from 23 countries, collected between March and May 2020. The results demonstrated that although online contacts help to reduce feelings of loneliness, people...

This paper makes a case for explaining diversity effects through cognitive factors as compared to demographic or other differences in backgrounds. We argue that studying perceived diversity in conjunction with diversity beliefs can explain positive and negative effects through a motivated opening or closing of the mind (Need for Cognitive Closure,...
Article
Objective: This research examines the relationship between passion for a romantic partner and obsessive relational intrusion (ORI) which is defined as repeated and unwanted behaviors toward a partner that invade his/her personal privacy and cause fear for his/her safety. Method: Based on the dualistic model of passion (Vallerand, 2015), we predi...

Background The effective implementation of government policies and measures for controlling the coronavirus disease 2019 (COVID-19) pandemic requires compliance from the public. This study aimed to examine cross-sectional and longitudinal associations of trust in government regarding COVID-19 control with the adoption of recommended health behaviou...
Article
Full-text available
The COVID-19 pandemic presents threats, such as severe disease and economic hardship, to people of different ages. These threats can also be experienced asymmetrically across age groups, which could lead to generational differences in behavioral responses to reduce the spread of the disease. We report a survey conducted across 56 societies (N = 58,...

Background Although there are increasing concerns on mental health consequences of the COVID-19 pandemic, no large-scale population-based studies have examined the associations of risk perception of COVID-19 with emotion and subsequent mental health. Methods : This study analysed cross-sectional and longitudinal data from the PsyCorona Survey that...
Article
This research examines how social networks contribute to the process of radicalization, building on work showing that obsessive (vs. harmonious) passion for a cause is linked to greater support for political violence. Study 1 (N = 331) shows that obsessive (vs. harmonious) passion is related to affiliating with radical (vs. moderate) social network...

Article
The psychological determinants of place attachment have thus far been explored only to a limited extent. We propose that the bonds humans develop with other humans (attachment styles) are consequential to understand the bonds individuals develop with places and spaces (place attachment). We examined this hypothesis in four studies. Study 1 (N = 101...

The purpose of this research is to experimentally test whether counter-narratives are effective to reduce people's support and willingness to join Islamic State of Iraq and Syria (ISIS). Integrating psychological reactance theory (Brehm, 1966) and need for closure (NFC; Kruglanski, 2004), we predicted that exposing people to counter-narratives when...

Study Objectives The present research examines the relationship between people’s frequent involvement in an activity they like and find important (i.e., a passion) and the quality of their sleep. Research on the dualistic model of passion1-2 has widely documented the relationship between individual's type of passion—harmonious vs. obsessive—and the...
Article
We propose and demonstrate in 11 studies, including more than 4,700 observations, that the persuasiveness of a target message can be increased by the inclusion of a reactance decoy. A reactance decoy is a persuasive message presented before the target message and includes an attitude measurement toward the decoy object. The effect can be explained...

This work is part of a larger study on the Energy Technology Preferences Survey, which explored the Australian population’s attitudes towards energy sources and technologies in Australia, with a particular emphasis on carbon capture and storage (CCS). An important aim of this survey has been to identify which factors are more strongly associated wi...
Article
Objective People that pursue a passionate activity obsessively (vs. harmoniously) tend to neglect (vs. integrate) other important life domains, yet research has been silent on the psychological mechanism explaining these differences in self‐regulation. The purpose of this research was to address this gap by testing the role of alternative goal supp...
Article
The present research tested whether increasing people’s ability to effectively manage multiple goal-pursuits would facilitate the satisfaction of their basic psychological needs and, in turn, promote harmonious (vs. obsessive) passion for an activity. Studies 1 and 2 provided cross-sectional and experimental evidence for the proposed model, respect...
Article
Full-text available
Adventure and excitement have often been invoked to explain why people engage in political violence, yet empirical evidence on the topic has thus far been anecdotal. The present research sought to fill this gap in knowledge by examining the role of sensation seeking in political violence and integrating this concept with Significance Quest Theory (...
Article
The present research demonstrates how support for political violence can be reduced by providing peaceful alternatives to produce social change. In Study 1, participants watched a video documenting the activities of a violent activist group, and then either watched a video of a peaceful activist group supporting the same cause or a control video. P...
