Abstract Research devoted to identify differences between expert and non-expert consumers in terms of wine quality perceptions, preferences, and information use and processing, have been prolific during the last decade. Many of these studies have used subjective or self-reported measures of knowledge to distinguish between expert and non-expert consumers. However, this approach can be problematic due to the existence of the Dunning-Kruger effect, a cognitive bias in which incompetent or unaware subjects tend to overestimate their knowledge or expertise, whereas high-ability individuals tend to underestimate it. The objective of this study was to explore the presence of this cognitive bias within the wine-knowledge domain. Using a sample of wine consumers (n = 193) and through different statistical analyses, the presence of the Dunning-Kruger effect was confirmed, raising important concerns regarding the use of subjective or self-reported measures of knowledge to classify consumers as experts or non-experts.

摘要 在过去的十年中,致力于识别专家和非专家消费者在葡萄酒质量感知、偏好以及信息使用和处理方面差异的研究一直是多产的。许多这些研究使用主观或自我报告的知识量度来区分专家和非专家消费者。然而,由于邓宁-克鲁格效应的存在,这种方法可能存在问题,这是一种认知偏差,在这种认知偏差中,无能或无意识的受试者倾向于高估他们的知识或专长,而能力强的人往往会低估它。本研究的目的是探索葡萄酒知识领域中这种认知偏差的存在。使用葡萄酒消费者样本(n = 193)并通过不同的统计分析,
