Leadership training focuses a great deal on the idea of using facts to move forward, especially in situations of contention, dissent, or set backs. Focus on the facts, not the interpretations. When you can put the emotions and individual interpretations, or as we like to call them, misinterpretations, aside, you can get right down to the issue at hand and make progress.
This often manifests in the utterance of the ever-so-soothing phrase “Stating problems without offering solutions is just whining”. Yep, that has about the same effect as telling an angry person to “Calm Down”.
