This study examined the relationship between White Americans' genetic explanations, conceptualized as genetic lay theories, for perceived racial differences and for sexual orientation, and attitudes toward Blacks, and gay men and lesbians, respectively. Considering contrasting public discourse surrounding race and sexual orientation, we predicted that genetic lay theories would be associated with greater prejudice toward Blacks, but less prejudice toward gay men and lesbians. The findings, based on a representative sample of 600 White Americans, were consistent with expectations. Results are discussed in relation to the literature on essentialism and implicit theories of the malleability of traits. The present research broadens our view of lay theories by showing how they support either prejudice or tolerance, depending on the target group.

It is predicted that the rapid acquisition of new genetic knowledge and related applications during the next decade will have significant implications for virtually all members of society. Currently, most people get exposed to information about genes and genetics only through stories publicized in the media. We sought to understand how individuals in the general population used and understood the concepts of 'genetics' and 'genes.' During in-depth one-on-one telephone interviews with adults in the U.S., we asked questions exploring their basic understanding of these terms, as well as their belief as to the location of genes in the human body. A wide-range of responses was received. Despite conversational familiarity with genetic terminology, many noted frustration or were hesitant when trying to answer these questions. In addition, some responses reflected a lack of understanding about basic genetic science that may have significant implications for broader public education measures in genetic literacy, genetic counseling, public health practices, and even routine health care.

Th authors investigated clergy's attitudes toward rape victims by using the Attitudes toward Rape Victims Scale and three rape scenarios (marital, date, and acquaintance). Clergy's sexism and religious fundamentalism were also measured. Results indicated that the more fundamentalist and sexist the clergy were, the more negative their attitudes toward rape victims. Qualitative analyses demonstrated that clergy take into account the woman's resistance, provocative behavior, decision making, marital role, and unusual behavior when assigning responsibility for rape. The results indicated that most clergy blame the victim and adhere to rape myths; therefore, they need to be more educated about sexual assault.

This paper examines three common explanations for human characteristics: genes, the environment, and choice. Based on data from a representative sample of White and Black Americans, respondents indicated how much they believed each factor influenced individual differences in athleticism, nurturance, drive, math ability, violence, intelligence, and sexual orientation. Results show that across traits: 1) Black respondents generally favor choice and reject genetic explanations, whereas White respondents indicate less causal consistency; 2) although a sizeable subset of respondents endorse just one factor, most report multiple factors as at least partly influential; and 3) among White respondents greater endorsement of genetic explanations is associated with less acceptance of choice and the environment, although among Black respondents a negative relationship holds only between genes and choice. The social relevance of these findings is discussed within the context of the attribution, essentialism and lay theory literature. The results underscore the need to consider more complex and nuanced issues than are implied by the simplistic, unidimensional character of the nature/nurture and determinism/free will debates -perennial controversies that have significance in the current genomic era.

Why do individuals have particular talents, skills, and abilities? Although various causal factors have been proposed, three explanations with strong social relevance have emerged as prominent: genes, the environment, and personal choice. These three factors play a central role in two major ongoing debates. The first, commonly termed the "nature/nurture" question, is typically conceptualized as a contrast between genetic (nature) and environmental (nurture) explanation. The second debate, frequently referred to as "determinism/free will," generally focuses on whether human nature is controlled by natural laws (genetic factors) and is therefore somewhat "determined," or is influenced by free will (personal choice). Although scholars note the obvious fallacies of framing these controversies in stark, "either/or" terms (e.g., Moore, 2001), it is crucial to understand the relative roles of these factors in people's everyday construals, especially given that commonsense explanations that people provide have important implications for how they react to their own and others' behaviors (Buchanan & Seligman, 1995;Weiner, 1986). This paper addresses two key questions: (1) which explanatory factor(s) do people offer to explain human characteristics?and (2) what are the interrelations among the perceived causal factors? Furthermore, given that causal beliefs often differ by ethnicity and social group (e.g., Marcus & Kitayama, 1991), our analysis considers the potential effect of ethnic group on these perceptions.What is the significance of our questions? First, burgeoning genetic research and t...
