Moralistic thinking on political left, right not so different

Sacred thinking isn't limited to political conservatives, according to a new report from researchers at the University of Illinois at Chicago and the University of Winnipeg.

The findings, from four related studies that examine how liberals and conservatives justify their political attitudes on same-sex-marriage and the Keystone XL oil pipeline, are published online by the journal Analyses of Social Issues and Public Policy.

"This study suggests that liberals and conservatives are more alike in their moral functioning than previously thought," says Matt Motyl, UIC assistant professor of psychology and corresponding author on the study.

The findings include:

• Liberals' support for same-sex marriage is rooted in their concerns about fairness; conservatives' opposition to same-sex marriages is rooted in their concerns about violations of the sacred order.
• Liberals' opposition to the development of oil pipelines is rooted more in concerns about fear of desecrating the environment; conservatives' support for the development of oil pipelines is rooted more in their concerns about (corporate) fairness.

In surveys about the oil pipeline issue, liberals' primary complaint was based on sanctity—and they claimed that sanctity was a more relevant consideration than did conservatives.

"The findings are the first, to our knowledge, to show that liberals can base their moral opinions on sanctity more than conservatives do when voicing opinions about culture-war issues," Motyl said.

According to the researchers, the different moral roots of liberal and conservative attitudes makes productive dialogue on important matters especially difficult.

"The culture war is mired in a stalemate partly because each side considers some matters to be sacrosanct and other matters as suitable for revision in the name of fairness," Motyl said. "Perhaps reframing these issues in nonsacralized terms could open opportunities for open-minded discussion."
