Ideological differences in the expanse of the moral circle
Nature said:Abstract
Do clashes between ideologies reflect policy differences or something more fundamental? The present research suggests they reflect core psychological differences such that liberals express compassion toward less structured and more encompassing entities (i.e., universalism), whereas conservatives express compassion toward more well-defined and less encompassing entities (i.e., parochialism). Here we report seven studies illustrating universalist versus parochial differences in compassion. Studies 1a-1c show that liberals, relative to conservatives, express greater moral concern toward friends relative to family, and the world relative to the nation. Studies 2a-2b demonstrate these universalist versus parochial preferences extend toward simple shapes depicted as proxies for loose versus tight social circles. Using stimuli devoid of political relevance demonstrates that the universalist-parochialist distinction does not simply reflect differing policy preferences. Studies 3a-3b indicate these universalist versus parochial tendencies extend to humans versus nonhumans more generally, demonstrating the breadth of these psychological differences.
Introduction
In 2006, then Democratic Senator Barack Obama bemoaned the country’s “empathy deficit,” telling college graduates, “I hope you choose to broaden, and not contract, your ambit of concern.” In 2012, Republican presidential challenger Mitt Romney said, “President Obama promised to begin to slow the rise of the oceans and heal the planet. My promise is to help you and your family.”
The distinction between Obama and Romney captures the distinct worldviews of American political liberals and conservatives, respectively. Romney prioritized the family unit, whereas Obama highlighted the planet broadly. This difference in parochialism versus universalism became exacerbated during the 2016 presidential election, with one article noting, “Trump vs. Hillary Is Nationalism vs. Globalism, 20161,” contrasting the more parochial Republican candidate with the more universalist Democratic candidate. Others have characterized the Trump administration’s policy decisions as battles between nationalists (typified by parochialism) and globalists (typified by universalism)2.
These differential tendencies toward parochialism and universalism on the political right and left, respectively, extend beyond the United States as well. For example, leading French right-wing politician, Marie Le Pen declared in 2016, “The gap is not between the Left and the Right, but between globalists and patriots. The globalists are acting for the dilution of France and its people in a huge worldwide magma. The patriots hope that the nation constitutes the most protective space for the French3.” Across Western Europe, ideological battles between the left and right have centered on this tension between universalism and parochialism.
