Biphobia
Biphobia refers to the prejudice, stigma, and discrimination directed against individuals who identify as bisexual, encompassing negative attitudes and behaviors from both heterosexual and gay/lesbian communities that question the validity or stability of bisexuality.[1] Common stereotypes include perceptions of bisexuals as confused, promiscuous, or merely transitioning through a phase toward exclusive homosexuality, with empirical surveys indicating that a notable portion of the population—such as 14.4% in one U.S. study—does not recognize bisexuality as a legitimate sexual orientation.[1][2][3] Research consistently links biphobic experiences to elevated health disparities among bisexuals, who exhibit higher rates of depression, anxiety, substance use, and suicidality compared to both heterosexual and exclusively homosexual individuals, often attributed to minority stress from dual discrimination and erasure.[1][4][5] Bisexuals report significant interpersonal and institutional invalidation, including exclusion from LGBTQ+ spaces where they face skepticism from monosexual peers, as well as assumptions of heteronormative privilege that overlook their unique vulnerabilities when in same-sex relationships.[3][1] Employment and healthcare settings also document bisexual-specific discrimination, contributing to poorer outcomes in professional and medical access.[6][7] While some studies note varying intensities of biphobic attitudes—such as higher negativity toward bisexual men than women or less overt bias from gay/lesbian versus heterosexual respondents—the phenomenon underscores bisexual invisibility as a persistent barrier to equitable recognition and support within broader sexual minority advocacy.[1][8] This dual-sided prejudice highlights causal pathways where monosexual norms reinforce stereotypes, exacerbating mental health burdens without the community buffers available to gay and lesbian individuals.[1][3]
