New research challenges the myth the as people get older they become more conservative. By comparing surveys of various age groups taken over a span of more than 30 years, sociologists found that in general, Americans' opinions veer toward the liberal as they grow older.

"All the evidence we have found refutes the idea that as people age their attitudes become more conservative or more rigid," said Nicholas Danigelis, a sociologist at the University of Vermont. "It's just not true. More people are changing in a liberal direction than in a conservative direction."

Danigelis and collaborators Stephen Cutler of the University of Vermont and Melissa Hardy of Pennsylvania State University analyzed data from the U.S. General Social Surveys of 46,510 Americans between 1972 and 2004. While the surveys did not provide data for the same individuals at different stages, they represented snapshots of the changing attitudes of respondents in different age cohorts over time. The researchers corrected for the fact that the age groups at different survey times are made of up new members with unique baseline opinions.

The surveys assessed attitudes on politics, economics, race, gender, religion and sexuality issues. In some cases, such as racial issues and questions of civil liberties for communists, the researchers measured a greater change toward liberalism in older people than in younger people.

"What we believe has happened, at least for the race relations, is that the older group, starting out at a position of significantly more negative feelings, had further to go," Danigelis told LiveScience.

If people really become more liberal as they age, why does common wisdom hold the opposite to be true?

People might find an average 60-year-old to be more conservative than an average 30-year-old, Danigelis said, but beware of extrapolating a trend. The older person, for example, might have started off even more conservative than he or she is now.

Danigelis also blamed the misconception on pervasive negative attitudes toward the elderly in our country, and stereotypes that depict seniors as rigid, ornery and set in their ways.
