与其他使用测谎技术的国家(尤其是美国)相比,中国不仅对测谎仪器的技术性问题的研究起步晚,理论研究薄弱,对规范其使用的法律制度基本上也处于空白状态。加之对测谎技术知识的匮乏和宣传上的一些误导,人们对测谎技术理解难免存在一些偏差,如测谎技术是测试人说的话是真是假、良好心理素质的人能逃过测谎、测谎结论是没用的、测谎技术是万能的、测谎技术就是仪器测试、测谎结论是仅从测试图谱得出的等,这些认识误区制约着测谎技术的发展和运用。本文就常见的测谎技术认识误区进行了剖析。 Compared with other countries that use polygraph technology (especially the United States), China not only started the research on the technical problems of polygraph instruments but also started to study the theory weakly. The legal system regulating its use is basically still in a blank state. In addition to the lack of technical knowledge of lie detector and some misleading publicity, people understand the polygraph inevitably there are some deviations, such as polygraph test is true or false testers say, people with good mental qualities can escape the polygraph, Polygraph conclusion is useless, polygraph technology is omnipotent, polygraph technology is instrumental testing, polygraph conclusion is derived from the test chart, etc. These misunderstandings restrict the development and application of polygraph technology. This article analyzes common misunderstanding of polygraph technique.
