The impact of knowledge on public attitudes toward scientific issues remains unclear, due in part to ill-defined differences in how research designs conceptualize knowledge. Using genetically modified foods as a framework, we explore the impacts of perceived familiarity and factual knowledge, and the moderating roles of media attention and a food-specific attitudinal variable (food consciousness), in shaping these relationships. Based on the differential effects on "negative attitudes" toward genetically modified foods, we provide further evidence that the measures of knowledge are separate concepts and argue against a one-dimensional view of scientific knowledge. We discuss implications for understanding the relationship between knowledge and science attitudes.
知识对公众对科学问题态度的影响仍不明确，部分原因在于研究设计对知识的概念化方式存在定义不清的差异。以转基因食品为框架，我们探讨了感知熟悉度和事实性知识的影响，以及媒体关注度和一个特定食品态度变量（食品意识）在塑造这些关系中的调节作用。基于对转基因食品“负面态度”的不同影响，我们进一步证明知识的衡量是不同的概念，并反对对科学知识的一维观点。我们讨论了理解知识与科学态度之间关系的意义。
