CMV: I think the world would be a better place if everyone practiced radical honesty.

Radical honesty is the practice of being explicitly honest about everything. This means no lies, not even white lies, but also no lying by omission, i.e. you can't just choose not to say something because it is regarded as impolite, taboo, or potentially hurtful to the other person.

Here's why I think it would be beneficial:

1. I don't think you can be genuinely close to someone if you lie to each other. Even in small ways, you aren't really knowing the person for how they are. In particular, people tend to tell small lies to make themselves be perceived in a favorable way by the other person - pretending to like something, pretending they didn't /did do some something which would make them look like a worse/better person, etc. I think this inhibits genuine closeness because you aren't able to accept someone for how they truly and completely are if you don't actually know them.

2. I think that people would benefit from this information. Some might argue that people will say hurtful things. However, consider a world without radical honesty: if people would have said these things with radical honesty, then it means they were already thinking them. Odds are, if people think these hurtful things, the other person has some type of impression or insecurity that other people think these things. Because people are too polite to say something, this person can never receive real confirmation of this fact though, which inhibits their ability to either change themselves or change the people they associate with. 

3. Everyone always fixates on the hurtful things that will be said, but I also think that lots of positive things will be said. Right now, its sort of weird to say things that are sort of sappy, but with radical honesty people would get used to that and it wouldn't be weird. As a result, people would feel more able to share their views, and this would improve relationships because people would actually express how grateful they are or how much they like another person.

4. I think that most of the harms that would come from people's blunt honesty would be cancelled out by other people's blunt honesty. For example, if someone says something rude or offensive, the other person can respond by saying that they think the other person is a total asshole (etc.)

Anticipatory Rebuttal:

Claim: People won't be able to handle the truth, they're too sensitive.

Response: At first, people might find it difficult. Over time, I think people would get desensitized to blunt, sometimes harsh honesty that I'm proposing.

Claim: Some people are better off delusional.

Response: I don't think that delusion is ever a stable, comfortable, or happy state of mind.  I think that delusional people, on some level, sort of know the truth or wonder about it often enough that it probably bothers them at least a little bit. In fact, I think that most people's insecurities aren't totally groundless (maybe I'm an asshole), and insecurity is just a characterization of the anxiety that a delusional person feels when they wonder about the truth. They'd be better off not having to wonder, so that they can move forward and either accept the situation, change themselves, or change the situation.

That's an oversimplifaction, and not something that people just "get used to" especially when you talk abou development.  Sometimes falsities can be used to encourage people to continue challenging themsevles and foster growth.  This is especially true with young children. What's a kindergarden teacher supposed to tell their students?  "Wow!  that's fingerpainting is awful, you drew all outside the lines."  No, the idea is that you encourage children to do what they like, so that they can continue to improve.  If you tell them they're bad at something, they're much more likely to not do it again, and they'll never get better.  This happens in every stage of education.  Not only that, but people are different.  Some children/people might handle constructive criticism better, while others might need a bit more finessing.  

Having blanket truthfulness without considering how people will handle it would lead to less productivity, particularly with children and healthy development.  They can't simply "get used to" it, because they havent developed emotional self awareness.
