One only has to look at the history of the last century to see extreme examples of what can happen when one group of people begin to believe that they are inherently superior to another group. Millions of people have died for being labeled as inferior or pagan. In a short period of time the population was reduced to just 5 million. The only way we can compensate for this part of our collective personality is to understand this natural instinct and be wary of anyone or any organization that perpetuates a philosophy of group superiority. We need to realize that we all fit in the classic bell curve of ability and intellect.
Some people are simply better at specific tasks than other people.
Task superiority doesn't make superior people. Each of us knows what we do well and what we don't do well. If each of us were asked to write down 3 things that we do well and three things that we didn't do well, we would be able to. What this really says is that we acknowledge that we do some things better than many other people and there are some things that other people do better than we can. When we recognize this fact, we can start to appreciate why individuals that can operate as a team always outperform a group of individuals that operate independently.
