The repertory grid method was used to determine what terminology respondents use to distinguish between different applications of genetic engineering drawn from food- related, agricultural, and medical applications. Respondents were asked to react to fifteen applications phrased in general terms, and results compared with a second study where fifteen more specific applications were used as stimuli. Both sets of data were submitted to generalized Procrustes analysis. Applications associated with animals or human genetic material were described as causing ethical concern, being (...) unnatural, harmful, and dangerous. Those involving plants or microorganisms were described as beneficial, progressive, and necessary. The results were validated in survey research, which indicated that general applications ofgenetic engineering were perceived as either positive or negative, whereas specific applications were more highly differentiated in perceptual terms. The results imply that the public debate about genetic engineering must take due account of the complexity of public concerns. (shrink)

Rational choice models are characterized by the image of the self-interested Homo economicus. The role of moral concerns, which may involve a concern for others' welfare in people's judgments and choices, questions the descriptive validity of such models. Increasing evidence of a role for perceived moral obligation within the expectancy-value-based theory of reasoned action and the theory of planned behavior indicates the importance of moral-normative influences in social behavior. In 2 studies, the influence of moral judgments on attitudes toward food (...) produced with the use of genetic engineering techniques and toward meat consumption is addressed. The reasons participants provide for their moral judgments indicate some foci of their moral concerns. The results of both studies corroborate earlier findings that perceived moral obligation has independent effects on behavioral intentions; they also provide evidence that such judgments may affect attitudes themselves. The results are discussed in relation to the need for attitude-behavior models to reflect the role of moral evaluations in judgment and choice. (shrink)

: Interesting work has been done on the striking similarities between the key arguments of the late Jacques Derrida and Daoism. While named otherwise, such Derridean signposts as the metaphysics of presence, the duality of language, and logocentrism are found in Daoist views of the relationship between reality, speech, writing, and knowledge. However, where the limits of language lead Derrida is different from where they take the authors of the Zhuangzi and the Daodejing, in particular regarding the question of action (...) for and responsibility toward others.

Source credibility has been thought to bean important determinant of peoples‘ reactions toinformation about technology. There has also been muchdebate about the need to communicate effectively withthe public about genetic engineering, particularlywithin the context of food production. Questionnaireswere used to investigate the impact of sourcecredibility, admission of risk uncertainty, andinitial attitude towards genetic engineering onattitudes of respondents after information provision.120 respondents with positive attitudes towardsgenetic engineering in food production were providedwith persuasive information about the technology,where both source attribution and admission (...) of riskuncertainty were systematically varied within theexperimental design. Impact on perceptions of sourcecredibility, informational qualities, and postintervention attitudes were examined, and compared toa second group of respondents who held initiallynegative attitudes towards genetic engineering, andwho had been exposed to similar informationinterventions. As predicted by Social Judgment Theory,initial attitude was found to be an importantdeterminant of post-intervention attitude. However,admission of risk uncertainty was also found to beinfluential in increasing acceptance and reducingrejection of the technology, possibly through thefacilitation of elaborative processing. Contrary toprevious research, prior attitudes had an impact onperceptions of both source credibility andinformational quality. In terms of effectiveinformation provision about genetic engineering, itwas concluded that scientific honesty is the bestpolicy, and that lay understanding of scientificprocess is probably greater than hitherto assumed byexperts.

Whilst there has been much debateregarding the importance of public acceptance ofgenetic engineering and its applications, there isevidence to indicate that objections to the technologyare likely to focus on specific applications of thetechnology, rather than genetic engineering per se.Thus it becomes important to examine the extent ofobjections associated with individual applications,rather than to assess public feeling regarding thetechnology overall. Survey data were collected from200 respondents regarding their objections to generalapplications of genetic engineering (where thetangible benefits were not obvious). Similar objectiondata (...) were collected from 200 different respondents,who were presented with specific applications withmore obvious tangible benefits. Overall patterns ofobjection to different applications were identifiedusing a novel method of objection mapping, inconjunction with analysis of variance to identifyindividual differences in the samples. For generalapplications, the results indicate that mostrespondents object less to applications involvingplants and microorganisms than to those involvinganimals or human genetic material. Individualdifferences in objection focus on applicationsinvolving animals or human genetic material, withwomen and those who are very concerned with theenvironment having greatest objections to theseapplications. Individual differences tend to reducewhen specific applications are used as stimuli,although the focus of concern is still on applicationsinvolving animals and human genetic material. However,gender differences were not statistically significant,and those respondents who have high levels ofenvironmental concern are differentiated by increasedobjections to large-scale agricultural applications.It is argued that effective communication regardingthe technology should focus on specific applications,and address issues of environmental impact within thecontext of these applications, if the public is tomake an informed choice regarding their acceptance ofthe products of the technology.

In this paper, dimensions of the debate surrounding the application of gene technology to food production are discussed and a study assessing perceptions of the technology among a sample of the UK public (n = 1499) is reported. The general picture that emerges from the study is one of people expressing low familiarity with the technology, with more people associating it with high risks than with low risks, and more people expecting it to provide low benefits than high benefits. Attitudes (...) towards different applications vary significantly, as does trust in different potential sources of information about the technology. It is also shown that attitudes can be predicted not only by estimates of risks and benefits but also by perceptions of the involvement of ethical issues, by the perceived need for the technology, and by the perceived likelihood of improvements it is likely to bring to the quality of life in the UK. The results are discussed in the context of the need for greater public information about the technology and the realization that communication of risks takes place within a complex network of societal relationships.

The development of genetic engineering and its plausible consequences raises a level of controversy that can be identified at the level of public rather than scientific debate. Opposition to genetic engineering may manifest itself in rejection of the technology overall, or rejection of specific aspects of the technology, where public attitudes may be defined by a complex set of perceptions incorporating risk, benefit, control, and ethical concerns.One hundred and seventy six members of the public responded to questionnaires about genetic engineering (...) that were framed in terms of either food production or medical application. The first section assessed perceived risks, benefits, and control of genetic engineering where the targets of the potential application and the location of control were varied. The second section assessed the relationship between objections to application of the technology to different types of organisms (plants, microorganisms, animals, or human genetic material). Questions were directed at either perceived risk or ethical objections. The applications of genetic engineering were seen as riskier and less beneficial when applied to food production than medicine, although perceived control was independent of application. Optimistic bias was observed. Ethical and risk related objections were greater for applications to food than to medicine, and again dependent on the type of organism manipulated. The transfer of genetic material between “dissimilar” types of organism (for example, between plants and animals) were not associated with greater risk or ethical concern than transfers between “similar” types of organism (for example, between animals and animals). The public requirement for legislative control was also dissociated into risk or ethical objections to the technology, and found to be greater for risk-related concerns, although ethical considerations were also important.
