摘要

Decreasing acceptance of biotechnologies over time has been reported in Europe. Studies claim that attitudes are negative, even hostile, and that people are very worried about genetic engineering in food and medicine. However, such studies are mostly based on surveys and these have significant methodological problems, such as low response rates, which may indicate that only those with strong views respond, thus biasing the sample. Here an alternative method, involving "topic-blind" recruitment of participants and a behavioral measure (food tasting), was used. We show that in a topic-blind sample of 100 individuals, 93% willingly tasted and ate what they believed to be genetically modified (GM) food in an experimental setting, and 48% said they would buy GM food in the future, results that are surprising in the context of other reports about attitudes and intentions toward GM food. Purchasers and nonpurchasers differed in their attitudes toward GM food on key risk-related scales (particularly on a dread-not dread scale—a measure of integral affect—and an ethical-unethical scale). Despite these differences, however, and despite their negative attitude, most nonpurchasers (85.7%) still tasted the GM apple. Incidental affect (state stress and trait worry) was not found to influence risk-related judgments about GM food. Integral affect (dread of GM plants and animals used for food) and concerns about the future risks of GM animals in food were found to be key predictors of willingness to purchase GM food.
