An experiment with 243 young communication scholars tested hypotheses derived from role congruity theory regarding impacts of author gender and gender typing of research topics on perceived quality of scientific publications and collaboration interest. Participants rated conference abstracts ostensibly authored by females or males, with author associations rotated. The abstracts fell into research areas perceived as gender-typed or gender-neutral to ascertain impacts from gender typing of topics. Publications from male authors were associated with greater scientific quality, in particular if the topic was male-typed. Collaboration interest was highest for male authors working on male-typed topics. Respondent sex did not influence these patterns.

In a polarized opinion climate, people may refrain from participating in publicly observable political activities that make them vulnerable to scrutiny and criticism by others who hold opinions that differ from their own. We took a dispositional approach to testing this claim by determining whether people who are relatively more influenced by the climate of opinion when choosing whether or not to voice an opinion, measured with the Willingness to Self-Censor scale [Hayes et al. International Journal of Public Opinion Research 17 (2005) 298], are also relatively less likely to engage in public political activities. In a poll of residents of the United States, we found that even after controlling for interest in politics, political ideology, ideological extremity, political efficacy, attention to political news, dispositional shyness, frequency of political discussion, and demographics, dispositional self-censors reported having engaged in relatively fewer public political activities over the prior 2 years compared to those less willing to censor their own opinion expression. These results are consistent with our interpretation of political participation as a social process that is governed in part by the social psychological implications of participation to the person. At a larger theoretical level, our findings
