What do you guys mean when you say society would "crumble"? I mean I think it's crazy enough that you can predict the effects on humanity of something this drastic.. but I'm curious to know what this "crumbling" entails.
Complete and total honesty would be a huge change, yes. But I'm not really sure why this would automatically make things "worse" than they are right now. People would eventually be born into this age of honesty and wouldn't even be able to understand how deception existed. A lot of people would long for the days when they could lie to people in order to make them feel better or hide their actual intentions during interactions, but I cannot understand how this would be a detriment to humanity. You'd just have to deal with the fact that people aren't as good, noble, etc as they would like you to believe.
