Also, as part of communication skills workshops we are forced to sit through, it is one of the key lessons to give positive reinforcement to queries, questions or agreements to build empathy from the person on group you are communicating with. Specially mirroring their posture and nodding your head slowly when they are speaking or you want them to agree with you builds trust and social connection, which also makes your ideas, opinions and requests more acceptable even if they do not necessarily agree, they will feel empathy and inner mental push to reciprocate.
Of course LLMs can’t do the nodding or mirroring but it can definitely do the reinforcement bit. Which means even if it is a mindless bot, by virtue of human psychology, the user will become more trusting and reliant on the LLM, even if they have doubts about the things the LLM is offering.
