Beyond Weird societies
In an increasingly globalized world challenged by multiple social problems, global social identifications (GSIs, e.g., with all humanity) are concepts of growing interest. Although such identifications can be affected by the cultural contexts in which they are manifested, research on them remains largely confined to Western, Educated, Industrialized, Rich, Democratic (WEIRD) societies. Using data collected in 45 countries ( N = 9807, preregistere…
Relationships Between Identification With All Humanity and Universalism and Benevolence
In three studies conducted in the United States (n = 598), Poland (n = 1000) and Chile (n = 311), we measured participants' Identification With All Humanity and their endorsement of Universalist and Benevolent values as defined by Schwartz and colleagues. In all three studies, when IWAH scores were regressed onto values scores, IWAH scores were significantly (positively) related to the endorsement of Universalism values and were not significantly…
The Ambivalent Role of Perceived Low Cultural Distance in Acculturation—A Case of Ukrainian Migrants in Poland
This study examines the role of perceived low cultural distance in the acculturation process of Ukrainian women (aged 22–31) who voluntarily migrated to Poland prior to 2019. Through qualitative analysis of 17 in-depth interviews, we explored how perceived cultural similarity between Poland and Ukraine is associated with the experiences of these migrants. Using reflexive thematic analysis, we found that while a perceived low cultural distance is …
Emotional Reactions to Protective Policies on the Political Spectrum
The need for safety is one of the basic human needs. States implement different protective policies to fulfil the task of granting safety to their citizens. Aim of the present study conducted online on a representative sample of Polish citizens ( N = 1,124), was to explore emotions potentially evoked by seven protective policies in the areas of: the economy, social welfare, health, personal security from crime and terrorism, one’s own way of life…
Potential changes in ties with people all over the world during the Covid-19 pandemic
The COVID-19 pandemic can be seen as a crisis affecting all humanity. It posed a collective threat, potentially strengthening ties with people all over the world through a feeling of interconnectedness and a common human fate. On the other hand, a sense of physical and psychological threat, competition for scarce resources, and closed national borders may have hindered such ties, worsened the perceptions of people all over the world, and focused …
The Identification With All Humanity (Iwah) scale
Identification with all humanity—A test of the factorial structure and measurement invariance of the scale in five countries
Identification with all humanity measured as an individual characteristic is an important factor related to social and international relations, such as concern for global issues and human rights, prosocial attitudes, intergroup forgiveness, attitudes toward immigrants, solving global problems, reactions to hate crimes and dehumanisation. We examine the factorial structure, psychometric properties and measurement invariance of the Identification w…
Stand out of my sunlight
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 reactions to preserve the ingroup’s interests. In this research, we investigate the relation between collective narcissism and attitudes towards climate science. We arg…

Global Human Identification and Citizenship
We review psychological research on global human identification and citizenship, Thomas Paine’s belief that “The world is my country, and all mankind are my brethren.” In turn, we review the theoretical foundations that guided our work, research with measures that preceded our own, and our own work with our correlated scales. We review its foundations, its effects upon attitudes and behaviors, and how it might be enlarged. Global human identifica…
What Is an “Ethnic Group” in Ordinary People’s Eyes? Different Ways of Understanding It Among American, British, Mexican, and Polish Respondents
Although the term “ethnic group” (EG) is often used in social studies, its definition differs among researchers. Moreover, little is known about ordinary people’s subjective understanding of this term, even though it is often used in social discourse. We examined this issue in a cross-sectional study of 273 American, British, Mexican, and Polish students using an open-ended questions approach. Results revealed cultural differences in patterns of …
The Influence of the Big Two
The present article concerns the relationship of the Big Two with generalized negative worldviews (i.e., negative beliefs about human nature and pessimistic expectations of interpersonal relationships). Morality/communion and competence/agency - in the form of generalized judgments concerning other people's attributes - may be a substantial basis for formulating negativistic beliefs about the social world. Because people automatically adopt the r…
