@Glomoro i think i see what you're getting at, though i still think that would be difficult to actually measure. adding to your point though, although the number of good or bad experiences may not be equal, the people who have had negative experiences can also be people who have had positive experiences, which would leave the difference down to the number of people who have had only negative or only positive experiences, which should be smaller.
also, i personally don't think there's a goldilocks zone of too little/too much information that can fully prevent misunderstandings. in that respect, i think having the ability to peacefully clear up misunderstandings is praiseworthy, especially on the internet where they come so easily and so often break out into arguments.
