Is the optimal outcome really the same as the one that would result from the most complete presentation of the facts? If you're buying an appliance, and you already agreed, and then the salesperson gives you additional info, you might change your mind ("oh, I thought the failure rate was 0.1%, you said it's 1%") even if in reality this may be a perfectly good enough appliance for you and a good sale for the seller. Optimal would probably be getting the sale done - even if that depends on untrue assumptions in your head not being challenged. Not getting the sale done means your back at square one, depending on what else you want to be doing with your time, that's not good. When interacting with another party you have a mental model you build to try to figure out what they're thinking, but it's very incomplete. Adding information can change your mind, and even not necessarily in a "true" way - imagine you're on a date, it's going well, both parties want to hook up... and then they say something that makes you think maybe their political views are offensive to you. You might be making a wrong assumption based on what they said. Or they might just disagree with you that much. But you're probably not going to have as much fun tonight anymore! You may have a more "true" outcome but is that what you wanted?
