Strategic attitude expressions as identity performance and identity creation in interaction.

We assess the strategic alignment of attitudes and the active construction of attitude-based identity across two studies. Study one assessed the twitter response (hashtags in English) to the war in Ukraine for five months after Russia's first invasion of Ukraine 2022 (N = 8149). Results demonstrated that individuals publicly expressed hashtags similar to others close to them in the followership network, showing their support for Ukraine and condemnation of the Russian invasion in qualitatively different ways.

The likes that bind: Even novel opinion sharing can induce opinion-based identification.

Research has found that psychological groups based on opinion congruence are an important group type. Previous research constructed such groups around opinions potentially connected to pre-existing identities. We strip away the socio-structural context by using novel opinions to determine whether opinion congruence alone can be a category cue which can foster identification and whether such group identification mediates the relationship between opinion exposure and opinion polarization.

Sharing is caring: How sharing opinions online can connect people into groups and foster identification.

Computer mediated communication has marked differences from the face-to-face context. One major difference is that, in the online context, we often have explicit access to others' opinions and these opinions are often the only informational cues available. We investigate if awareness of opinion congruence, in the absence of any other reference categories, may be sufficient to foster social identification.
