Factors Influencing People's Acceptance of Gene Technology: The Role of Knowledge, Health Expectations, Naturalness, and Social Trust

This article aims to examine which factors influence people's perception of gene technology. Data come from a mail survey in the German speaking part of Switzerland (N = 830). Principal component analyses for acceptance, risks, and benefits of 12 gene technology applications resulted in two factors: one related to medical applications and the other to nonmedical applications. Results showed that three different types of knowledge did not substantially influence perceived risks or perceived benefits of gene technology. Overall results suggest that the experiential system and not the analytical system determines lay people's perception of gene technology.
