在两个实验中，当被要求评估基因技术的好处时，参与者表现出偏见的反应。他们评估了由于一种新引进的品种而在玉米田里增加产量的重要性，这将增加农民的收入。在一种情况下，新引进的品种被描述为传统育种的产品；在另一种情况下，它被鉴定为转基因(GM)。这两个实验的结果表明，当转基因作物与传统种植作物相比，同样的好处对农民来说不那么重要。中介分析表明，感知的自然性和与技术本身相关的影响影响对新信息的解释。缺乏基因技术的自然性似乎是参与者在基因技术条件下感知到的新玉米品种的收益低于传统育种条件下参与者感知到的收益的原因。通过引进更好地满足消费者和生产者需求的植物品种来提高人们对基因技术的接受度的战略可能不会奏效，因为人们对其相关好处不屑一顾。
In two experiments, the participants showed biased responses when asked to evaluate the benefits of gene technology. They evaluated the importance of additional yields in corn fields due to a newly introduced variety, which would increase a farmer's revenues. In one condition, the newly introduced variety was described as a product of traditional breeding; in the other, it was identified as genetically modified (GM). The two experiments' findings showed that the same benefits were perceived as less important for a farmer when these were the result of GM crops compared with traditionally bred crops. Mediation analyses suggest that perceived naturalness and the affect associated with the technology per se influence the interpretation of the new information. The lack of perceived naturalness of gene technology seems to be the reason for the participants' perceived lower benefits of a new corn variety in the gene technology condition compared with the perceptions of the participants assigned to the traditional breeding condition. The strategy to increase the acceptance of gene technology by introducing plant varieties that better address consumer and producer needs may not work because people discount its associated benefits.
