Using data obtained from Spanish surveys on the public perception of science, this article presents a critical review of current practices of population profile segmentation, including the one-dimensional representation of perceived risks and benefits and of the systematic underestimation of critical attitudes to the social impact of science and technology. We use discriminant analysis to detect a somewhat hidden cluster in the Spanish population which we call 'critical engagers'. These individuals are critically and socially responsible and are not reticent about expressing concern regarding scientific-technological change. While they hold an overall positive attitude towards change of this kind, they are at the same time well aware of the risks posed by particular fields of application. We highlight the academic interest and political value of these individuals, attributing to this population a mature and intelligent stance which may well be employed in enhancing the relationship between science and society.

identify the specific pathways involved, which will likely vary by type of cancer.Finally, the increased risk of diabetes after cancer development was similar in women (fully adjusted hazard ratio [aHR], 1.31; 95% CI, 1.19-1.46) and men (aHR, 1.38; 95% CI, 1.26-1.52; P = .53 for the interaction). This risk was also observed across all ages, but the association was stronger in younger participants (aHR in participants <50 years of age, 1.70; 95% CI, 1.49-1.96) than in older participants (aHR in participants ≥50 years of age, 1.26; 95% CI, 1.17-1.37; P = .53 for the interaction).

This paper examines the frequency of midpoint responses in agree/disagree scales in a survey measuring attitudes toward science and scientific policy, a low-salience and difficult topic. It also examines the contribution of individual differences to explain the tendency to select this option. It is assumed that the use of the midpoint “Neither agree nor disagree” (NA/ND) in Agree/Disagree (A/D) scales is to some extent an indication of satisficing. It is also assumed that there are individual differences in respondents’ tendency to select the NA/ND response. Using a Generalized Linear Mixed Model we include Krosnick’s regulators of satisficing, socio-demographics and individual differences as predictors. We find that the contribution of the regulators of satisficing identified by Krosnick is small. In turn, factors associated with individual differences explain a great amount of variance on the number of NA/ND responses. We conclude that the presence of this option in a survey of a low-salience topic increases satisficing as strategy of the respondents to deal with the cognitive burden of both the A/D scale and the difficulty of the topic. Furthermore, the number of NA/ND responses may be understood as an indicator of individual differences in the propensity of respondents to satisficing when answering a survey on a low-salience or difficult topic.
