The reliability of confessions is subject to a variety of factors, some of which give rise to expert testimony. To the degree that prosecutors construe the determination of reliability as an objective standard, they may attempt to bar testimony. Moreover, when the testimony is theoretical rather than clinical, there are additional challenges. Depending on jurisdiction, the admissibility of expert testimony on whether a confession was knowing, intelligent, and voluntary is subject to a legal threshold such as the Frye or Daubert standard. The authors review a 2002 New Jersey Superior Court ruling that illustrates the forces that shape the admissibility of confessions.
供述的可靠性受到多种因素影响，其中一些因素引发了专家证词。在检察官将可靠性判定视为客观标准的程度上，他们可能会试图禁止证词。此外，当证词是理论性而非临床性的时候，还会有其他挑战。根据司法管辖区的不同，关于供述是否出于明知、明智且自愿的专家证词的可采性要遵循诸如弗赖伊标准或达伯特标准之类的法律门槛。作者回顾了2002年新泽西高等法院的一项裁决，该裁决说明了影响供述可采性的各种因素。
