While positive attitudes toward lesbians and gay men have increased, a new study – led by researchers at IU’s Center for Sexual Health Promotion – shows attitudes toward bisexual men and women are relatively neutral, if not ambivalent.

The study, which is only the second to explore attitudes toward bisexual men and women, was led by Brian Dodge, associate professor in the Department of Applied Health Science and associate director of the Center for Sexual Health Promotion at Indiana University’s School of Public Health-Bloomingtom.

He said,

While recent data demonstrates dramatic shifts in attitude (from negative to positive) toward homosexuality, gay/lesbian individuals and same-sex marriage in the U.S., most of these surveys do not ask about attitudes toward bisexuality or bisexual individuals. And many rely on convenience sampling strategies that are not representative of the general population of the U.S.”

The study looked at five negative connotations, found in previous studies, associated with bisexual men and women, including the idea that they are confused or in transition regarding their sexual orientation, that they are hypersexual and that they are vectors of sexually transmitted diseases.

The research showed that a majority of male and female respondents, more than one-third, were most likely to “neither agree nor disagree” with the attitudinal statements. In regard to bisexual men and women having the capability to be faithful in a relationship, nearly 40% neither agreed nor disagreed.

Those who identified as “other” had the most positive attitudes toward bisexuality, followed by gay/lesbian respondents and then heterosexuals.

Age played a factor in the results, with participants under the age of 25 indicating more positive attitudes toward bisexual men and women. Income and education also played a role: Higher-income participants were more likely to report more positive attitudes toward bisexual men and women, in addition to participants with higher levels of education.

Overall, attitudes toward bisexual women were more positive than attitudes toward bisexual men.

While our society has seen marked shifts in more positive attitudes toward homosexuality in recent decades, our data suggest that attitudes toward bisexual men and women have shifted only slightly from very negative to neutral. That nearly one-third of participants reported moderately to extremely negative attitudes toward bisexual individuals is of great concern given the dramatic health disparities faced by bisexual men and women in our country, even relative to gay and lesbian individuals.”

Bisexual men and women face a disproportionate rate of physical, mental and other health disparities in comparison to monosexuals—those who identify as exclusively heterosexual and exclusively homosexual, Dodge said. Although research has not determined the cause, Dodge said that negative attitudes and stigma associated with bisexuality could play a role.

Data from the National Survey of Sexual Health and Behavior shows that approximately 2.6% of adult men and 3.6% of adult women in the U.S. identify as bisexual. For females, that number is more than double the number of women who identify as lesbian, 0.9%. When it comes to adolescents, 1.5% of male adolescents (age 14 to 17) and 8.4% of female adolescents identify as bisexual.

Dodge said he hopes the results emphasize the need for efforts to decrease negative stereotypes and increase acceptance of bisexual individuals as a component of broader initiatives aimed at tolerance of sexual and gender minority individuals.

After documenting the absence of positive attitudes toward bisexual men and women in the general U.S. population, we encourage future research, intervention and practice opportunities focused on assessing, understanding and eliminating biphobia—for example, among clinicians and other service providers—and determining how health disparities among bisexual men and women can be alleviated.”
