Considering a new idea doesn't mean you have to buy into it hook, line, and sinker. It simply means that you're willing to listen to the idea and evaluate it on its logical merits. A big part of that is getting your facts right, before stating your opinions. That's the art of persuasion. A healthy way to look at open-mindedness is to learn all you can about a subject while removing or minimizing the emotional aspect.
Keep an open mind and a level head.
