Brain research shows that the brain develops and creates the infrastructure to think and learn well after birth and that environment and external stimuli enhance or inhibit this process. All people are not equal. Each person has different abilities. A team's critical needs will be met when you recognize this and strive to pull from each member based on their unique abilities. Having said this, it is even more important to discuss respect.
People tend to value certain abilities more than they value others.
Some of the highest paid people in our society are athletes and entertainers. Some people believe a person with lots of money is important. If you went to the right school or come from the right neighborhood you are a better person. Well, all of these ideas have one fundamental flaw. The person deserves respect, not what they have.
