The horror of today and the terror of tomorrow: The role of future existential risks and present-day political risks in climate activism.

In response to the urgent global climate crisis, climate activism has risen as a potent force. Decision-making regarding climate collective action includes individuals' perceptions of the anticipated future existential risks of the climate crisis (risk of inaction) and present-day political risks of climate activism (risk of action). Our research, spanning four studies (two correlational surveys and two pre-registered experiments), focused on climate activism in Germany (N = 1027).

Beyond normative and non-normative: A systematic review on predictors of confrontational collective action.

This paper critically examines the normative versus non-normative distinction commonly used in collective action research. To explore the similarities and differences between antecedents of normative versus non-normative actions, we conducted a systematic review on diverse predictors of non-normative, radical and violent collective actions. We examined 37 social and political psychology studies published after 2010 and identified five recurring themes: identity, efficacy, injustice, emotions and norms.

The roles of social norms and leadership in health communication in the context of COVID-19.

The global struggle with the COVID-19 pandemic has lasted for almost three years. Although national and local leaders have often called on the public to comply with preventive measures through health communication, large sections of society sometimes violated precautions and did not adequately follow these calls. We propose that social norms and leaders' identity entrepreneurship characteristics could be essential in effective health communication.

Predicting attitudinal and behavioral responses to COVID-19 pandemic using machine learning.

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.

Does social influence affect COVID-19 vaccination intention among the unvaccinated?

Conformist social influence is a double-edged sword when it comes to vaccine promotion. On the one hand, social influence may increase vaccine uptake by reassuring the hesitant about the safety and effectiveness of the vaccine; on the other hand, people may forgo the cost of vaccination when the majority is already vaccinated - giving rise to a public goods dilemma. Here, we examine whether available information on the percentage of double-vaccinated people affects COVID-19 vaccination intention among unvaccinated people in Turkey.

Beyond the Choice of What You Put in Your Mouth: A Systematic Mapping Review of Veganism and Vegan Identity.

In recent years, and in the current climate crisis, the interest in veganism and sustainable diet/lifestyle has increased. This growing interest can also be seen within academia. Therefore, we set out to systematically document and organize the social psychological literature on veganism and vegan identity to identify where the field currently is, and what we need to do next.

Adaptive function and correlates of anxiety during a pandemic.

Background And Objectives: Most studies to date have focused on the negative aspects of anxiety. Anxiety, however, is an evolved emotional response that can provide protection in the face of risk. Pandemics are characterized by increased mortality risk coupled with future uncertainties, which both cause heightened anxiety.

Effective incentives for increasing COVID-19 vaccine uptake.

In this study, we examined the relative effectiveness of prestige-based incentives (vaccination of an expert scientist/president/politician/celebrity/religious leader), conformist incentives (vaccination of friends and family) and risk-based incentives (witnessing death or illness of a person from the disease) for increasing participants' chances of getting vaccinated with respect to their coronavirus disease 2019 (COVID-19) vaccine intention. We conducted a cross-cultural survey using demographically representative samples from the UK ( = 1533), USA ( = 1550) and Turkey ( = 1567). The most effective incentives in all three countries were vaccination of an expert scientist, followed by vaccination of friends and family members and knowing someone dying from the disease.

The role of ethnic identification, allyship, and conflict narratives in supporting pro-minority policies among majority and minority groups.

Objectives: Using the context of the Turkish-Kurdish conflict, Studies 1 and 2 tested how ethnic identification predicted support for minority rights through the pathway of the endorsement of the conflict narrative of the minority group (i.e., independence narrative) among Kurds (Study 1) and Turks (Study 2) in Turkey.
