Contempt before investigation
Oh, this is a road well-travelled in my noggin, so I know of what I speak. Many of us approach new decisions with a preconceived notion of what is the correct course of action. Perhaps we've been down the road before. Perhaps we're experts on the topic.
But in a remarkably dynamic environment like digital, it makes sense to solicit alternative ideas before you take action. You might make an even better decision. But, more importantly, you give those who work with you the sense that their ideas matter -- that they are integral parts of the team. You might still take the course of action you first identified. You might make another decision. But you will have arguably done something even more important: energize your team by caring about their points of view.
