Trueblood、Brown和Heathcote（2014）开发了一个新模型，称为多属性线性弹道累加器（MLBA），用于解释多选项选择中的情境偏好逆转。MLBA被证明通过对选择数据的定性分析和定量拟合提供了对人类行为的良好描述。Tsetsos、Chater和Usher（2015）研究了MLBA同时捕捉3个突出的情境效应（吸引力、妥协和相似性）的能力。他们得出结论，MLBA必须在竞争力量之间建立一个“微妙的平衡”，以同时考虑所有3种影响，并且其预测对属性空间中刺激的位置很敏感。通过一项新的实验，我们发现这三种效应非常脆弱，只有一小部分人同时表现出这三种效应。因此，在新的实验中，Tsetsos等人从MLBA模型中产生的预测结果与真实数据非常吻合。对这些预测的支持为MLBA提供了强有力的证据。一个推论是，一个能够同时“稳健地”捕捉所有3种效应的模型不一定是一个好模型。相反，一个好的模型捕获在人类数据中找到的模式，但不能容纳没有找到的模式。
Trueblood, Brown, and Heathcote (2014) developed a new model, called the multiattribute linear ballistic accumulator (MLBA), to explain contextual preference reversals in multialternative choice. MLBA was shown to provide good accounts of human behavior through both qualitative analyses and quantitative fitting of choice data. Tsetsos, Chater, and Usher (2015) investigated the ability of MLBA to simultaneously capture 3 prominent context effects (attraction, compromise, and similarity). They concluded that MLBA must set a "fine balance" of competing forces to account for all 3 effects simultaneously and that its predictions are sensitive to the position of the stimuli in the attribute space. Through a new experiment, we show that the 3 effects are very fragile and that only a small subset of people shows all 3 simultaneously. Thus, the predictions that Tsetsos et al. generated from the MLBA model turn out to match closely real data in a new experiment. Support for these predictions provides strong evidence for the MLBA. A corollary is that a model that can "robustly" capture all 3 effects simultaneously is not necessarily a good model. Rather, a good model captures patterns found in human data, but cannot accommodate patterns that are not found.
