The undue influence of genetic information on senior medical students' treatment decisions.

Background: Knowledge of the genetic basis of health conditions can influence how the public perceives their own and others' health. When there are known genetic associations for such conditions, genetic essentialist biases facilitate deterministic thinking and an over-emphasis of genetic causality. This study investigates the role that genetic essentialist biases play in medical decision-making.

BIDAR: Can Listeners Detect if a Man Is Bisexual from His Voice Alone?

Previous research has identified a range of perceptual voice and speech features that differ between gay and straight men, enabling listeners to determine if a man is gay or straight at a rate better than chance from his voice alone. To date, no published studies have examined if bisexual men's voices differ from gay and straight men's voices with regard to perceived masculinity-femininity - nor whether listeners can identify a bisexual man based only on his voice. In the present study, we examined if listeners could identify bisexual men's sexual identities from voice recordings.

Do Beliefs About Sexual Orientation Predict Sexual Identity Labeling Among Sexual Minorities?

Research has found that sexual orientation beliefs predict heterosexuals' attitudes toward sexual minorities, and important sexual identity outcomes in sexual minority populations. To this point, no studies have systematically examined how sexual orientation beliefs may be associated with sexual identity self-labeling among sexual minority individuals. The present study examined this question in a sample of 1840 same-gender attracted individuals recruited for a cross-sectional online survey.

Exposure to continuous or fluid theories of sexual orientation leads some heterosexuals to embrace less-exclusive heterosexual orientations.

We examined whether heterosexual individuals' self-reported sexual orientation could be influenced experimentally by manipulating their knowledge of the nature of sexual orientation. In Study 1 (180 university students, 66% female) participants read summaries describing evidence for sexual orientation existing on a continuum versus discrete categories or a control manipulation, and in Study 2 (460 participants in a nationally representative Qualtrics panel, 50% female) additionally read summaries describing sexual orientation as fluid versus stable across the life-course. After reading summaries, participants answered various questions about their sexual orientation.

Genetic essentialism: The mediating role of essentialist biases on the relationship between genetic knowledge and the interpretations of genetic information.

Purpose: Genetic research, via the mainstream media, presents the public with novel, profound findings almost on a daily basis. However, it is not clear how much laypeople understand these presentations and how they integrate such new findings into their knowledge base. Genetic knowledge (GK), existing causal beliefs, and genetic essentialist tendencies (GET) have been implicated in such processes; the current study assesses the relationships between these elements and how brief presentations of media releases of scientific findings about genetics are consumed and affect the readers.

Why Do Some Gay Men Identify as "Straight-Acting" and How Is It Related to Well-Being?

Recent literature has described the phenomenon of "straight-acting" gay men: gay men who identify with traditional heteronormative masculinity. The current study examined predictors of "straight-acting" identification in gay men and how identifying as straight-acting relates to well-being. A sample of Australian gay men (N = 966) provided self-report data on two potential predictors of straight-acting identity: self-perceived masculinity and internalized homophobia.

Do Bisexuals Have a Bisexual Viewing Pattern?

Past visual attention research appears to show that bisexual men and women view erotic images differently compared to heterosexual and gay/lesbian men and women. However, none of these studies have employed analytic approaches required to determine whether these apparent bisexual viewing patterns are due to averaging together heterosexual and gay/lesbian type viewing patterns, or rather are because bisexual-identified individuals possess unique viewing patterns which are distinct from heterosexual and gay/lesbian individuals. In the current eye-tracking study, we aimed to address this question.

Visual Attention to Sexual Stimuli in Mostly Heterosexuals.

Individuals who report mostly heterosexual orientations (i.e., mostly sexually attracted to the opposite sex, but occasionally attracted to the same sex) outnumber all other non-heterosexual individuals combined.

Genetic Knowledge within a National Australian Sample: Comparisons with Other Diverse Populations.

Background: Genetic knowledge, which plays important functions in our understanding of science, health, social groupings, and even behaviour, has been evaluated in past studies with various populations. This wide reach of genetics means that different types of items are used to assess genetic knowledge, which restricts meaningful comparisons across time- and locale-based studies.

Aim: The present study addresses this limitation by recruiting an Australia-wide sample and evaluating their genetic knowledge using items sourced from four diverse samples.

Causal Reasoning About Human Behavior Genetics: Synthesis and Future Directions.

When explaining the causes of human behavior, genes are often given a special status. They are thought to relate to an intrinsic human 'essence', and essentialist biases have been shown to skew the way in which causation is assessed. Causal reasoning in general is subject to other pre-existing biases, including beliefs about normativity and morality.

Born this way: Sexual orientation beliefs and their correlates in lesbian and bisexual women.

In this study, we examined how beliefs about the nature and origin of sexual orientation were associated with sexual identity outcomes, namely internalized sexual stigma and sexual orientation uncertainty, and in turn, psychological well-being in sexual minority women. A community sample of 393 lesbian and 205 bisexual women were recruited for a cross-sectional online survey. Using multigroup structural equation modeling, we examined whether believing sexual orientation to be inborn/immutable (i.

Who Adopts Queer and Pansexual Sexual Identities?

Some nonheterosexual individuals are eschewing lesbian/gay and bisexual identities for queer and pansexual identities. The present study aimed to examine the sexual and demographic characteristics of nonheterosexual individuals who adopt these labels. A convenience sample of 2,220 nonheterosexual (1,459 lesbian/gay, 413 bisexual, 168 queer, 146 pansexual, and 34 other "write-in") individuals were recruited for a cross-sectional online survey.

Essentialist beliefs, sexual identity uncertainty, internalized homonegativity and psychological wellbeing in gay men.

The present study examined essentialist beliefs about sexual orientation and their implications for sexual identity uncertainty, internalized homonegativity and psychological wellbeing in a sample of gay men. A combination of targeted sampling and snowball strategies were used to recruit 639 gay identifying men for a cross-sectional online survey. Participants completed a questionnaire assessing sexual orientation beliefs, sexual identity uncertainty, internalized homonegativity, and psychological wellbeing outcomes.

Minority stress and community connectedness among gay, lesbian and bisexual Australians: a comparison of rural and metropolitan localities.

Objective: To determine whether lesbian, gay and bisexual (LGB) Australians residing in rural-remote and other non-inner metropolitan localities experience increased levels of minority stress and reduced social support relative to their inner metropolitan counterparts.

Methods: A convenience sample of (n=1306) LGB Australians completed an online survey that assessed minority stressors, level of connection with other LGB individuals and social isolation. Postcodes provided were coded into three metropolitan and two rural zones.
