Tóm tắt

There is a need to develop effective communication strategies with the public about the risks and benefits of applied genetic engineering. The Elaboration Likelihood Model was used to systematically investigate the impact of source factors (trust) and the perceived personal relevance of information, including the persuasiveness of the information, on attitudes towards genetic engineering, and whether these factors resulted in more thoughts about genetic engineering. The results from 160 respondents indicated an interaction between source effects and persuasiveness. People tended to respond more to information low in persuasiveness if it was attributed to a highly trusted source, and more to information high in persuasiveness if it were from a source low in public trust. In this context, respondents tended to express concern about the technology. It was concluded that source characteristics are important determinants of public responses to information about genetic engineering.
