Individual Differences
people have much in common, but each person in the world is also individually different. The idea of individual differences is strongly supported by science. Each person is different from the others, probably in million ways. One is the DNA of every person, where it is unique even to twin sisters or brothers. This idea originated from psychology. From the day of birth, each person is unique, and individual experiences after birth make people even more different. The belief that each person is different from all others is typically called the law of individual differences.
Perception
People look at the world and see things differently. Even when presented with the same object, two people may view it in different ways. Their view of their objective environment is filtered by perception, which is the unique way in which each person sees, organizes and interpret things. People use an organized framework that they have built out of lifetime of experiences and accumulated values. Having unique views is another way in which people insist on acting like human beings rather than rational machines.
Motivated Behavior
From psychology we learn that normal behavior has particular causes. These may relate to a person’s needs and or the consequences that result from acts. In the case of needs, people are motivated not by what we think they ought to have but what they themselves want. To an outside observer, a person’s needs may be unrealistic, but they are still controlling.
Value of the Person
People deserve to be treated differently than other things because they are of the higher order in the universe. They want to be treated with care, respect, dignity and even demand more. They refuse to accept the idea that they are just economic tools, especially during work. They want to be valued with their skills and abilities.
