Active pro-vaccine and anti-vaccine groups: Their group identities and attitudes toward science

Vaccine rejection is a problem severely impacting the global society, especially considering the COVID-19 outbreak. The need to understand the psychological mechanisms underlying the active involvement of the pro-vaccine and anti-vaccine movements is therefore very important both from a theoretical and practical perspective. This paper investigates the group identities of people with positive and negative attitudes towards vaccination, and their attitudes toward general science. A targeted sample study of 192 pro-vaccine and 156 anti-vaccine group members showed that the group identity of pro-vaccine individuals is higher than of anti-vaccine individuals. and that both pro-vaccine and anti-vaccine individuals had a positive attitude toward science. Results are discussed in context of the heterogeneity of motivations causing vaccine rejection and the relation between active involvement in online discussion and group identity.

Yau̯nā and Sakā: Identity Constructions at the Margins of the Achaemenid Empire

The Achaemenid Empire can be reasonably considered an “empire of peoples” from both an ideological and structural perspective. It included all the lands of the peoples of the world and all people helped to maintain imperial order and prosperity. In reality, the empire had boundaries and there were peoples who lived near and beyond them. Under King Darius I, groups of people were annexed at the northeastern and northwestern margins of the imperial territory, thus entering the imperial space and consequently also the Achaemenid documents. The border peoples of the Yau̯nā and Sakā were the only peoples of the empire to be differentiated through epithets, which were added to their collective names in the texts. This shows a unique process of group identity constructions by the authorities on the edges of the imperial space. The analysis of the system of epithets used to indicate the Yau̯nā and Sakā conducted in this paper allows us to draw some conclusions on the mechanisms and reasons behind these specific forms of identity constructions at the margins. Moreover, it shows how this process reflected the main directions of imperial expansion under the first Achaemenids.

The Participatory Implications of Racialized Policy Feedback

How do involuntary interactions with authoritarian institutions shape political engagement? The policy feedback literature suggests that interactions with authoritarian policies undercut political participation. However, research in racial and ethnic politics offers reason to believe that these experiences may increase citizens’ engagement. Drawing on group attachment and discrimination research, we argue that mobilization is contingent on individuals’ political psychological state. Relative to their counterparts, individuals with a politicized group identity will display higher odds of political engagement when exposed to authoritarian institutions. To evaluate our theory, we draw on the 2016 Collaborative Multiracial Post-Election Study to examine the experiences of Blacks, Latinos, and Asian Americans. For all subgroups and different types of institutions, we find that, for those with a politicized group identity, institutional contact is associated with higher odds of participation. Our research modifies the classic policy feedback framework, which neglects group-based narratives in the calculus of collective action.
