现有的理论诱饵的属性值的评价效果进行了评估方面的能力，占一个一维模拟的不对称优势效应。Parducci（1965，1995）的距离-频率理论、Krumhansl（1978）的距离-密度模型、Tversky（1977）的诊断原理和参考点理论（例如，Holyoak & Mah，1982）无法解释这种效应。Helson（1964）的适应水平理论和我们的比较诱导失真理论（Choplin & Hummel，2002）的一个版本能够解释定性效应。定量拟合表明，比较引起的失真理论提供了一个更好的帐户这种效果比适应水平理论。这些结果表明，在某些情况下，语言表达的幅度比较所产生的偏见介导的诱饵评价的影响。
Extant theories of decoy effects on evaluations of attribute values were assessed with respect to their ability to account for a one-dimensional analogue of the asymmetric dominance effect. Parducci's (1965, 1995) range-frequency theory, Krumhansl's (1978) distance-density model, Tversky's (1977) diagnosticity principle, and reference point theories (e.g., Holyoak & Mah, 1982) were unable to account for this effect. One version of Helson's (1964) adaptation-level theory and our comparison-induced distortion theory (Choplin & Hummel, 2002) were able to account for the qualitative effect. Quantitative fits revealed that comparison-induced distortion theory provides a better account of this effect than does adaptation-level theory. These results suggest that, in some cases, biases created by language-expressible magnitude comparisons mediate the effects of decoys on evaluation.
