Most research on political identities studies how individuals react to knowing others’ political allegiances. However, in most contexts, political views and identities are hidden and only inferred, so that projected beliefs and identities may matter as much as actual ones. We argue that individuals engage in motivated political projection: the identities people project onto target individuals are strongly conditional on the valence of that target. We test this theoretical proposition in two pre-registered experimental studies. In Study 1, we rely on a unique visual conjoint experiment in Britain and the USA that asks participants to assign partisanship and political ideology to heroes and villains from film and fiction. In Study 2, we present British voters with a vignette that manipulates a subject’s valence and solicits (false) recall information related to the subject’s political identity. We find strong support for motivated political projection in both studies, especially among strong identifiers. This is largely driven by negative out-group counter-projection rather than positive in-group projection. As political projection can lead to the solidification of antagonistic political identities, our findings are relevant for understanding dynamics in group-based animosity and affective polarization.

We study learning and selection and their implications for possible effort escalation in a simple game of dynamic property rights conflict: a multi-stage contest with random resolve. Accounting for the empirically well-documented heterogeneity of behavioral motives of players in such games turns the interaction into a dynamic game of incomplete information. In contrast to the standard benchmark with complete information, the perfect Bayesian equilibrium features social projection and type-dependent escalation of efforts caused by learning. A corresponding experimental setup provides evidence for type heterogeneity, for belief formation and updating, for self-selection and for escalation of efforts in later stages.

This study focused on social projection (SP) to outgroups. Two studies were conducted to show that SP to outgroups was greater than to ingroups when an issue is more relevant to the outgroup than to the ingroup and vice versa. These experiments were conducted for students of different schools (N1 = 92, N2 = 203). The results confirmed that students overestimated agreement with working adults when the topic was more relevant to working people. Also, when the topic was relevant to students, they overestimated agreement of other students relative to the working adults. These results suggested the relevance of the opinion was more important than perceived social distance when Japanese students refer to others.
