What is the most difficult part of rapport building for investigators?

Building rapport is a crucial skill for investigators, as it establishes trust and creates a conducive environment for communication. Sincerity is the most difficult aspect because it involves genuine engagement and authenticity with the subject. An investigator must convey a true interest in the person's situation, which can be challenging, especially in high-stress or emotionally charged environments.

When an investigator is perceived as sincere, the individual is more likely to open up, share information, and feel safe during the interaction. If the investigator's sincerity is in question, it can create barriers that hinder effective communication and the gathering of important information. Strong rapport relies heavily on this genuine interaction, making sincerity not only vital but often a challenging skill to master.
