Most of us are not very familiar with this term but we do know what means. Most people talk about this idea as the ability to see the bigger picture and the ability to theorize and assess possibilities. I'm not too great at it either but my wife is and speaking to her about a situation is always very helpful. We look at it from different perspectives and together we get a better, more accurate grasp of the issue at hand.
People should always discuss these ideas with one another. Bouncing ideas off others is great to fill in the gaps of our own thinking. Regardless of how intelligent we are, sometimes it's just very difficult to think in different ways.
