I've probably never changed a deeply held belief after a single conversation, but my beliefs have changed over time and those changes have been aided by discussions I've had along the way. I think it takes me a long time to form a strong view on something and, once formed, it also takes a long time to change or abandon that view. Even if I participate in a conversation where relevant new information is imparted to me or my reasoning is shown to be flawed, I'm likely to take that away and chew it over (and do my own research) before changing my position.
