The Verifiability Approach (VA) is a verbal veracity tool that assumes that truth tellers provide more details that can be verified and obtain a higher ratio of such details (verifiable details/total details) than liars. A VA meta-analysis was conducted. Results showed that truth tellers reported more verifiable details than liars (k = 20, N = 1532, g = 0.42). The effect was moderated by the presence of the information protocol and by the nature of the statement (event-related or not). Truth tellers reported a higher ratio of verifiable details than liars (k = 18, N = 1359, g = 0.49). The effect was moderated by the medium through which the statement was provided. Unverifiable details did not discriminate truth tellers from liars (k = 15, N = 957, g = −0.25). In conclusion, results showed good potential for the use the VA, although replications and field studies are needed.

可验证性方法（VA）是一种语言准确性工具，它假定真相讲述者提供了更多可以验证的细节，并且比说谎者获得更多此类细节（可验证细节/总细节）的比率。进行了VA荟萃分析。结果表明，真相讲述者报告的细节要多于说谎者（k = 20，N = 1532，g = 0.42）。信息协议的存在和语句的性质（无论是否与事件相关）都减轻了影响。真相实话者报告的可验证细节比例比撒谎者高（k = 18，N = 1359，g= 0.49）。通过提供陈述的媒介减轻了影响。无法验证的细节并未将真相讲述者与说谎者区分开（k = 15，N = 957，g = -0.25）。总之，尽管需要重复和现场研究，但结果表明使用VA的潜力很大。
