It helps in a way that the chatbot knows more about the person's personality than people may have realized. And that is helpful it comes to therapy communication and state of mind. IMHO
However, the way I think about it is that people respond better to different way of communication, and knowing a person's preferred styled of communication will be helpful in helping a person open up and get to the root of issue.
Right, do you mind expanding on this? I'm curious but I struggle to understand. Maybe if you have an example that might help.
