Introduction
Associate Professor in the Institute of Psychology, Polish Academy of Sciences (Warsaw, Poland). My primary research interests are predictors and social consequences of broad social identifications (in particular identification with all humanity). My other research interests include criteria of belonging to national groups in a cross-cultural context, attitudes toward religious symbols in public space and understanding of ambiguous terms by laypeople (e.g. “ethnic group”).

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...

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 foundati...

Superordinate identities, such as identification with all humanity (IWAH), may be considered the result of situational activation or as individual differences that can be measured using psychometric scales. Our research originates from this second approach. Why do some people feel connected only to narrow social groups like family and friends, whil...
Article
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 st...
Article
Highlights • We clarify mixed results on national identification's role in intergroup forgiveness. • We propose dual-path model of national identification in intergroup forgiveness. • National identity indirectly constrains forgiveness through collective narcissism. • National identity indirectly enhances forgiveness through human identification.

The Identification With All Humanity (IWAH) scale was designed to measure the extent to which an individual identifies oneself with all human beings. The current research aimed to conduct the validation of IWAH in a Chinese population and its convergent validity, as well as test the implications of IWAH in associations with help-seeking behaviour d...

In the present research, we focus on COVID-19 vaccine hesitancy, and empirically examine how different forms of social identity (defensive vs. secure national identity and identification with all humanity) and conspiracy beliefs are associated with COVID-19 vaccine hesitancy. In two cross-sectional nationwide surveys (Study 1, n = 432, and Study 2,...

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...

To sum up 10 months of our research on the well-being of Poles during the pandemic, we notice its negative effects: between March and May/June, life satisfaction decreased and the feeling of loneliness increased. Fortunately, we saw no further declines in these areas in December. However, a sense of having social support dropped. The condition of...

Article
Prior research suggests two components of multicultural experiences—contact with cultural members and experiences with cultural elements—predict less prejudice via stronger identification with all humanity (IWAH). However, only one factor of IWAH (bond) was tested, and only United States samples were used. The present research examined both factors...

Article
Many studies have shown a positive link between multiple social identities and well-being. However, these studies have usually examined a few selected identities in this context. We examine many more social identities, expecting positive relationships between the number of social identities and well-being. Moreover, we explore the number of social...
Article
There is mixed evidence on the role of national identification in intergroup forgiveness after historical crimes. We propose that this is due to the dual character of national identification, which consists of a general sense of belonging (shared with supranational identifications) and a more specific sense of distinctiveness. Study 1, performed on...
Article
Full-text available
Intergroup forgiveness may be granted by members of a victimized group to members of a transgressing group, even if the transgression took place a very long time ago, and all actors and witnesses of atrocities in question are already dead. This makes such secondhand forgiveness different from interpersonal forgiveness, but still some elements are s...

Raphael Lemkin is hardly known to a Polish audiences. One of the most honored Poles of the XX century, forever revered in the history of human rights, nominated six times for the Nobel Peace Prize, Lemkin sacrificed his entire life to make a real change in the world: the creation of the term “genocide” and making it a crime under international law....

By detailed analyses of Polish and world statistics, the authors search for the answer if in fact, as some politicians and citizens claim, the world and in particular European Union and Poland are overcome by the wave of violence.

Article
We tested how often people smile from different reasons and how sex as well as agency and communion (while controlling for need for approval) modify these tendencies. There were 217 subjects, aged 19-60, from different places of residence. As the results showed, subjects declared positive reasons for smiling significantly more often than negative r...

Abstract. 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 substanti...
Article
Studying broad social identities allows us to understand the relation between an individual and the globalizing, multicultural social world. Identification with all humanity is one of the widest social identities existing. Individuals strongly identifying themselves with people all over the world feel close to them, care for them and perceive them...
Chapter
In two studies it was checked if biological sex influences the type and strength of social identifications of men and women, in particular broad identifications, e.g. with all humanity. Sex stereotypes would allow us to predict stronger and broader identifications among women than men (H1a), although some studies suggest opposite direction (H1b) (e...
Article
Full-text available
Social ties are known to have strong influence on well-being, but in the studies in this scientific context they are usually operationalized as close relationships. The author wanted to check if social identifications with very big groups and communities e.g. citizens of a province, a nation, citizens of Europe or a religious group, are also linked...

Full-text available
Globalization has opened up the possibility of widening an individual's sense of belonging to broader and perhaps more abstract commonalities, such as Europe or humanity. The more locally bounded identities, such as identification with one's nation or family, coexist with broader conceptual understandings of the world as a whole. The chapter discus...

Question
Dear colleagues,‎
We are conducting a meta-analysis on methods and results of situational activation of global social identities (global human identity, global citizenship identity, etc.). We would like to ask for your help with gathering published and unpublished studies for the meta-analysis process.‎ We are interested in any of the following situations:
when global identity was used as manipulation and/or when another manipulation was used to change the level of global identification.
We would appreciate references to any published data on this issue to make sure we have included them in our meta-analysis. More importantly, we are especially interested in any relevant unpublished manuscripts or unpublished ‎data that cannot be found through a regular literature search.
If you have unfinished or unpublished manuscripts, we would appreciate a copy. These will be kept ‎confidential and will not be used for any other purpose other than inclusion in the meta-analysis (with a reference).
If you only have raw data that has not yet been analyzed, then we would be happy to help analyze it in exchange for ‎inclusion (with a reference). In such a case, please send us the dataset and a description of the key variables, relevant for the analysis.‎
Please send all relevant information and/or data to us at this email khamer@psych.pan.pl or khamer@khamer.eu by the end of April. If you have doubts, whether your study meets the criteria, please contact us as well.
Please, pass this request to any colleagues who might be conducting relevant research. Thank you for your help.
Kind regards,‎
