Political conservatives worry about fear of chaos and absence of order while political liberals operate out of a fear of emptiness, they say.
How did they arrive at those conclusions?
"Social scientists long have assumed that liberals are more rational and less fearful than conservatives, but we find that both groups view the world as a dangerous place," says McAdams. "It's just that their fears emerge differently. Social scientists, who are generally liberals, have for decades done research to figure out what makes conservatives tick."
Like the Northwestern study, the preponderance of research finds that conservatives fear unchecked human impulses that challenge the status quo. What McAdams and Northwestern researcher Albaugh also find is an underlying, but different, fear that drives liberals as well.
"Political conservatives envision a world without God in which baser human impulses go unchecked, social institutions (marriage, government, family) fall apart and chaos ensues," says McAdams. Liberals, on the other hand, envision a world without God as barren, lifeless, devoid of color and reasons to live.
"Liberals see their faith as something that fills them up and, without it, they conjure up metaphors of emptiness, depletion and scarcity," McAdams said. "While conservatives worry about societal collapse, liberals worry about a world without deep feelings and intense experiences."
The study findings may shed light on why conservatives prefer more authoritarian leaders while liberals do not, he adds.
"What's clear is that it is their political and not religious orientation that underlies the different psychologies of political conservatives and liberals," says McAdams. After all, all of the adults he and Northwestern researcher Albaugh studied were members of churches, and their data suggested that most were socially involved, altruistic people.
The Northwestern University study sample included 128 highly religious and politically active Americans who attend church regularly. Although nationally conservatives are more likely to attend church than liberals, the Northwestern study was set up to sample equally from religious conservatives and religious liberals.
The researchers also observed gender differences, but said they did not interfere with the relationship between political orientation and narrative themes. The study is part of a larger project that looks at the relationships of faith, politics and life stories in well-functioning American adults. It is funded by the Foley Family Foundation in Milwaukee.
