MADISON, Wisconsin — When forming attitudes about embryonic stem cell research, people are influenced by a number of things. But understanding science plays a negligible role for many people. That’s the surprising finding from a team of University of Wisconsin-Madison communications researchers who have spent the past two years studying public attitudes toward embryonic stem cell research. Reporting in the most recent issue of the International Journal of Public Opinion, the researchers say that scientific knowledge – for many citizens – has an almost negligible effect on how favorably people regard the field. ‘More knowledge is good – everybody is on the same page about that. But will that knowledge necessarily help build support for the science?’ says Dietram Scheufele, a UW-Madison professor of life sciences communication and one of the paper’s three authors. ‘The data show that no, it doesn’t. It does for some groups, but definitely not for others.’ Along with Dominique Brossard, a UW-Madison professor of journalism and mass communication, and graduate student Shirley Ho, Scheufele used national public opinion research to analyze how public attitudes are formed about controversial scientific issues such as nanotechnology and stem cells.
