My take on this is that most of society is much better able to have the skills to accomplish external-oriented tasks, such as building a road or engineering. I believe where society and humans lack is in the area of insight and internal/intellectual traits. This can be said for any society or "tribe". Humans seem to have a basic tribal instinct, where they fail to analyze the facts/reality and fail to really understand what is going on (not understand things just from their point of view, but from different points of view, and at least try to look at the facts). People in general seem to put forth very little effort to have good judgment, do what is best for everyone, and understand what matters and what doesn't, etc. Humans can achieve so much. Look at Apple, and all of the other inventions and advancements society has made. It's incredible. But the same people involved in those incredible achievements may get home and take out all their anger on their family. Or do drugs. Or run over people in business. This shows the disconnect between internal understanding/intelligence and external understanding/intelligence. I feel that the reasons people turn out the way they do is because of many different factors: upbringing, experiences, genetics, development, etc. But I have to believe that a 'lack of insight' is not completely do to these factors. I believe there is some choice involved. I believe people always have the choice of at least trying to look at the facts, and trying to understand things. The fact that most people don't shows that they either truly do not have insight, or are not putting forth internal efforts to come from a more rational point of view.
