“Facing the ‘shoulds’ of life–other people’s ideas of how we should be living our lives–is a constant challenge,” said Bella DePaulo, a social psychologist and visiting professor of psychology at UC Santa Barbara. She has published a new book debunking what she labels as the myth that married people live longer, happier lives than their single counterparts.

In “Singled Out: How Singles Are Stereotyped, Stigmatized, and Ignored, and Still Live Happily Ever After” (St. Martin’s Press, 2006) DePaulo exposes what she considers a widespread bias against unmarried adults, as seen in everything from missed perks to deeper social and financial prejudices.

“There’s a whole cottage industry on marriage research,” DePaulo said. “There are journals, which have been in existence for 50 years, and grant funding for people who want to study marriage. But there’s very little for people who want to study singlehood. And this is the case at a time when there are almost 90 million single people in the United States.”

The demographic face of the country has changed dramatically over the past several decades, according to DePaulo. The U.S. population now consists of more than 87 million Americans who are divorced, widowed, or have always been single. In addition, Americans now spend more of their adult lives single than they do married.

“Yet people are stereotyped, stigmatized, marginalized, or discriminated against for being single,” she said. “It’s called ‘singlism,’ and a lot of it is legal.” She cited laws that allow married workers to add spouses or domestic partners to their health care plans at reduced rates, while single workers are not afforded the same benefit, as an example of singles receiving unequal compensation for the same work.

She also noted that single men often get paid less than married men, despite doing the same work at the same level of seniority and competence, “Single people subsidize married people in smaller ways, too,” she added. “For example, married people often get discounted rates on auto insurance, club memberships, and travel packages, while singles pay full price.”

DePaulo examined studies that concluded married people live longer and more happily than singles and found flawed science behind many of them. In contrast, as an example of an especially high-quality study, she cited an 18-year, Michigan State University research project that asked married and single people to rate their degrees of happiness on an annual basis.

“Looking at the quantified results, you can see how happy the participants were in the years before getting married, how happy they were in the early years of marriage, and how happy they were later on,” she said. “There was a little blip around the wedding and honeymoon, but overall it showed that…being happy has more to do with individual personalities than (marriage).”
