국민참여재판에서 판사가 배심원에게 제시하는 법설시에는 범죄사실에 대해서 합리적인 의심이 없는 정도의 증명에 이르렀을 때 유죄를 인정해야 한다는 “합리적 의심의 초월 기준”에 대한 설명이 포함된다. 합리적 의심의 초월 기준은 일반적으로 배심원들이 평의를 시작하기 직전에 설명되는데, 본 연구에서는 설시절차(증거 이전, 증거 이후)에 따라 피고인에 대한 유죄/무죄 인정에 차이가 생긴다는 선행연구를 기반으로 그 인지과정을 알아보고자 하였다. 배심원 자격을 가진 만 20세 이상 성인남녀 189명을 대상으로 합리적 의심의 초월 기준에 대한 설명을 증거 전과 후에 받은 집단이 증거 후에만 설시를 받은 집단과 설시를 받지 않은 집단보다 피고인에 대한 유죄인정비율이 낮은지 분석한 후, 설시 제시절차와 유죄인정비율 사이의 두 가지 인지과정을 확인하였다: 1) 유죄판단 역치 생성, 2) 증거의 증명력 평가. 분석 결과, 설시를 증거 전후에 받은 집단은 다른 집단에 비해 피고인의 유죄를 판단하기 위한 역치가 높게 형성된 것을 확인하였으나, 증거의 증명력은 설시 제시절차 간에 유의한 차이가 없었다. 이러한 결과는 배심원이 재판에서 설시를 증거 전에 받았을 때, 각 증거의 증명력을 합리적 의심의 초월 기준으로 평가하기보다는 유죄결정을 위한 역치수준을 조정하여 그것을 기반으로 피고인에 대한 최종판단을 한다고 해석되었다.

Abstract
The jury instruction consists of a set of legal rules and provides a guide for jurors to interpret evidence and the legal standard of a proof beyond reasonable doubt. Jury instructions are usually given after the closing arguments (at the end of the trial). But some research has shown that jury instruction provided before the evidence may have an impact on verdict. The present study was to determine the cognitive process caused by early instruction: (1) Early instruction may influence the verdict by upwardly adjusting the threshold for the decision to convict; (2) early instruction may influence the verdict through evaluations of the probative values of evidence; (3) Or both. 187 people older than 20 years of age participated in the on-line survey. With a trial scenario, one independent variable, Instruction Procedure, was manipulated in three levels: before-and-after the evidence procedure, after-only evidence procedure, and no-instruction procedure. The instruction procedure conditions did not show any difference in the evaluation of the probative values of evidence. On the other hand, before-and-after condition showed the lowest rate of guilty verdict and the highest probability of guilt for the defendant in the scenario. This latter result clearly suggested that the instruction procedure affects the decision threshold. Specifically, instruction provided twice, once before and again after the evidence, may upwardly shift the threshold for the decision to convict.
