It represents the existence of built-in uncertainties in the test and indicates how the test, in general, and the examiners, in particular, bear this limitation in practice. Unfortunately, it is so common that most examiners tend not to spend too much time and attention wondering about its meaning. The following are some reflections on the concept of an Inconclusive Zone, and its actual use, including some resulting recommendations. That includes internal aspects of the test, such as the relation between the extent of using multiple comparison points between relevant and comparison questions and the optimal Inconclusive Zone size. External aspects affecting the Inconclusive Zone’s size and shape are also stressed when looking at the CQT through a prism of aiding decision-making rather than a mere means to sort truth from lies.enUznanie autorstwa-Użycie niekomercyjne-Bez utworów zależnych 3.0 PolskaComparison Question TestCQTInconclusive ZonePolygraphTrue score theoryPay-off matrix in polygraph decisionsPrawoArtykuł2380-055010.2478/ep-2022-0008
