The missionaries would often use this scripture to ask me to conduct various ‘experiments’ to help me recognize the manifestations of the holy spirit. Worse, they would often use methods which introduced further bias. For example they would ask me to pray by asking God if the Book of Mormon was true. They would then bear testimony that they know the Book of Mormon is true and they are sure if I’m sincere then I will come to know as well. At our next meeting they would ask me what I felt when I was reading and praying, especially did I feel good or peaceful (as if the only way I would feel peaceful while reading is if the holy spirit were speaking to me). That technique, suggesting what an investigator will feel when they pray, is prone to the observer-expectancy effect in which the missionaries_ cognitive bias affects the investigator’s. It is an attempt to avoid this bias that many courts do not allow leading questions during direct examination.
