As far as I can tell, most people, while engaging in real-time conversations, do not feel this discomfort of having insufficient time and resources to verify the other participant's claims (or for that matter, to make sure that one's own speech is not erroneous). Is it because they are too credulous, and haven't developed an instinctive skepticism of every new idea that they hear? Or do they just not take the other person's words seriously (i.e., "in one ear, out the other")?
