科学家们普遍认为转基因食品可以安全食用（1，2），并有可能为人类带来实质性利益（3）。然而，许多人仍然对它们表示担忧或反对使用它们（4，5）。在一个具有全国代表性的美国成年人样本中，我们发现，随着对转基因食品的极端反对和担忧的增加，对科学和遗传学的客观知识减少，但对转基因食品的理解增加。极端的对手知道的最少，但认为他们知道的最多。此外，自我评估和客观的知识之间的关系从积极的到消极的高水平的反对。在对来自美国、法国和德国的代表性样本进行的一项平行研究中，以及在一项测试对基因工程技术的医学应用（基因治疗）的态度的研究中，也获得了类似的结果。然而，这种模式并没有出现在对气候变化的态度和信念上。
There is widespread agreement among scientists that genetically modified foods are safe to consume(1,2) and have the potential to provide substantial benefits to humankind(3). However, many people still harbour concerns about them or oppose their use(4,5). In a nationally representative sample of US adults, we find that as extremity of opposition to and concern about genetically modified foods increases, objective knowledge about science and genetics decreases, but perceived understanding of genetically modified foods increases. Extreme opponents know the least, but think they know the most. Moreover, the relationship between self-assessed and objective knowledge shifts from positive to negative at high levels of opposition. Similar results were obtained in a parallel study with representative samples from the United States, France and Germany, and in a study testing attitudes about a medical application of genetic engineering technology (gene therapy). This pattern did not emerge, however, for attitudes and beliefs about climate change.
