I agree, with the caveat that it doesn't work with people acting in bad faith (e.g. liars, manipulators, narcissists). In those cases, communication often makes situations worse. Of course bad faith should never be assumed, but once it has been demonstrated, it's hard to forget—if someone was willing to lie once to get what he wanted, how do I know he'd be unwilling to lie again?

For the vast majority of people, though, communication is better.
