Consumer acceptance of transgenic crops

It has long been recognised that a key determinant of the future development of genetic engineering in food production is likely to be consumer acceptance. Much of the earlier research into acceptance issues has assumed that public perceptions of genetic engineering are defined by beliefs about the technology overall. However, it is now known that acceptance of novel products is unlikely to be related to general attitudes towards genetic engineering. People's perceptions of risk and benefit associated with particular products and applications will determine acceptance. There is a need to develop effective risk–benefit communication strategies, based on the best scientific information available, in order to enable the public to make informed choices about consuming the products of genetic engineering. It is also essential to develop effective communication methods if the public is to contribute to the wider debate about strategic development of genetic engineering. Issues of social context (such as trust in risk regulators) must also be considered. Providing information is likely to change people's attitudes, which will in turn generate further public concerns and create a demand for more information about genetic engineering. © 1998 SCI     

‘Objection’ mapping in determining group and individual concerns regarding genetic engineering

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.     

The influence of initial attitudes on responses to communication about genetic engineering in food production

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.     

Ethical concerns and risk perceptions associated with different applications of genetic engineering: Interrelationships with the perceived need for regulation of the technology

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.     

Defining European preparedness and research needs regarding emerging infectious animal diseases: results from a Delphi expert consultation

Emerging and major infectious animal diseases can have significant international impact on social, economic and environmental level, and are being driven by various factors. Prevention and control measures should be prepared at both national and international level to mitigate these disease risks. Research to support such policy development is mostly carried out at national level and dedicated transnational research programmes are still in its infancy. This research reports on part of a process to develop a common strategic research agenda on emerging and major infectious diseases of livestock in Europe, covering a 5-15-year time span. A two round online Delphi study was conducted to explore the views of experts on issues relating to research needs on emerging infectious diseases of livestock in Europe. Drivers that may influence the incidence of emerging infectious animal diseases in both the short (next 5 years) and medium term (10-15 years) were identified. Drivers related to regulatory measures and biological science developments were thought to decrease the incidence, and socio-economic factors to increase the incidence of emerging infectious animal diseases. From the first round a list of threats to animal health was compiled and participants combined these threats with relevant drivers in the second round. Next to identifying threats to animal health, also possible mitigatory actions to reduce the negative impact of these threats were identified. Participants emphasised that interdisciplinary research is needed to understand drivers of emerging infectious animal diseases, as well as to develop prevention and control measures which are both socio-economic and technical. From this it can be concluded that interdisciplinary research combining both natural and social research themes is required. Some of the European member states research budget needs to be allocated so that effective prevention and mitigation strategies can be developed.     

Gene technology,food production,and public opinion: A UK study

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.Paul Sparks is a social psychologist at the Institute of Food Research, Reading, UK.
