英文文献摘要：
An experiment was conducted to investigate the interaction between consumers’ past eating behaviors, risk perceptions and future information processing procedure. In the study, participants were required to choose whether or not to eat chicken that was potentially be tainted with Avian Influenza (AI). Results showed that people decreased the consumption when facing ambiguous signals regarding the food quality, but would not cease to eat altogether. Due to a taste of consistency, participants updated their risk perceptions and judgments based on their eating behaviors. The more chicken individuals ate the more favorably they tended to rate the food, suggesting confirmatory bias. Even though consumers with previous experience could pick up signals faster, their judgment was not better than those non users due to a much stronger psychological bias. This study offered an explanation for why consumers were universally irresponsive to public food safety information.

在这项研究中，参与者被要求选择是否吃可能被禽流感(AI)污染的鸡肉。结果显示，当面对有关食物质量的模糊信号时，人们会减少消费，但不会完全停止进食。由于口味的一致性，参与者根据自己的饮食行为更新了他们的风险认知和判断。人们吃的鸡越多，他们对食物的评价就越好，这表明了确认性偏见。尽管有经验的消费者能够更快地捕捉信号，但他们的判断并不比那些非用户好，因为他们有更强的心理偏见。这项研究解释了为什么消费者普遍对公众食品安全信息反应迟钝。
