One limitation of stated-preference methods is the formation of hypothetical bias. To address this, the honesty oath has been used as an ex ante technique to reduce hypothetical bias. Our study provides a query account of the honesty oath in a discrete-choice experiment setting by using Query Theory to examine the mechanism behind the effectiveness of the honesty oath. Our results show that the honesty oath can change the content and order of queries; potentially reducing hypothetical bias in discrete choice experiments. The study suggests the potential usefulness of Query Theory in examining thought processes of respondents in valuation studies.

宣誓下离散选择实验的查询理论说明

陈述偏好方法的局限性是假设偏差的形成。为了解决这个问题，诚实宣誓已被用作事前技术以减少假设偏见。我们的研究通过使用查询理论研究诚实宣誓效力背后的机制，为离散选择实验设置中的诚实宣誓提供了一个查询帐户。我们的结果表明，诚实宣誓可以改变查询的内容和顺序。可能会减少离散选择实验中的假设偏差。该研究表明查询理论在评估估值研究中受访者的思维过程中的潜在实用性。
