Moral value conflicts in the German debate about genetically engineered foods

The German debate about genetically engineered crops for human consumption (GE) has been polarized for nearly three decades. Efforts to overcome this polarization generally involve distributing information, but research indicates that information has little to no impact on GE attitudes, especially among those with extreme positions. Recent studies suggest that moral value concerns drive GE opposition. However, the specific moral values underlying both support and opposition for GE are unknown, as is whether these values differ between GE supporters and opponents. The present research addresses these questions through latent content analysis. Findings show that most arguments in the debate address moral value concerns related to loyalty, often focusing on trust issues. Trust issues are more prevalent than moral concerns about preventing harm and risks. Furthermore, moral value conflicts are likely since GE supporters emphasize concerns related to authority, fairness, and liberty, while GE opponents focus more on values related to care and purity. This paper discusses these findings and recommends steps for improved science communication.
