Why Do Some Societies Make Disastrous Decisions?

In "Why Do Societies Make Disastrous Decisions" by Jared Diamond, he goes on to explain how societies have fallen. Diamond gives four categories in which he believes attributes the fall of societies and how they move on or recover. "First is that a society may fail to anticipate a problem before it arrives, then when it does arrive they fail to perceive it. After that they may fail to try to solve it, then lastly fail to successfully solve the problem." Not only are big groups responsibly for the decision making that results in failure, but the individual that make up those groups play a big role in the whole societies outcome and existence. A good example that Diamond uses and that I have seen with the particular issue of Global Warming, is the term he used "creeping normalcy." Referring to that the reason some of us fail to do something is because "we fail to notice a developing problem, until its too late." All of our decisions lead to good or bad outcomes that are are to predict what to do next.. As Diamond said, we should look at close situations from the past that relate to current ones and use them as a resource to make the next decision in solving a problem. Hopefully from this we can better determine what is right for our society and what we have to do to keep it going.
