From the materials discussed below, I think this line is very important:
*"People tend to assess the relative importance of issues by the ease with which they are retrieved."
Think about that -- importance that is determined by the abundance of coverage (determined by the media) and not by what is most pressing, critical, or needed. If something can be easily found, it certainly means that it has been a topic of discussion. But we cannot conclude it is focusing on the key issues. Do we pay attention to what is being thrown at us? Or do we spend time on those subjects that are most important to us, our families, our jobs, our churches, etc.
