For whom do boundaries become restrictions? The role of political orientation.

While the global pandemic highlighted the importance of adhering to boundaries (e.g., social distancing rules), compliance with these boundary-imposing measures has been politically divided. This research proposes one reason that may underlie the observed ideological asymmetries toward COVID-19 prevention measures and boundaries in general: Conservatives and liberals may fundamentally differ in how they construe boundaries. Supporting this prediction, Studies 1a-1d and two follow-up studies ( = 3,231; Studies 1a-1c and follow-up studies: Amazon Mechanical Turk and Prolific users, Study 1d: U.S. students) demonstrate that identifying with political conservatism (vs. liberalism) increases the likelihood to construe boundaries as restrictions. We further show that, due to conservatives' greater preference for order, structure-related words carry a more positive connotation among conservatives versus liberals (Study 2: = 744; MTurk users). Capitalizing on this finding, we demonstrate that linguistic framing that highlights the structure-providing function of a boundary (e.g., a social distancing sign can "structure" customer flow in a restaurant) can reduce the salience of its usual restrictive aspect and hence effectively improve conservatives' attitudes toward the boundaries (Study 3: = 740; MTurk users).
