Humans don't have the goodness of character of most other primates. All they have is intellect which may give them technological advantage but moral inferiority and lack of integrity.
According to Harvard Professor Howard Gardner, Cliffy, human intelligence is multidimensional:
"Social Intelligence (SI) is the ability to get along well with others, and to get them to cooperate with you ... SI is one of a cluster of "intelligences," according to the theory of multiple intelligences advanced by Professor Howard Gardner of Harvard University ... The old idea that a person's potential in life can be measured and predicted by a single number - his or her "IQ" score - has lost a great deal of credibility during the last decade or so."

Moral intelligence/integrity are heavily influenced by worldview and will.
If I believe that human beings are created in the image and potential of a Supreme Being, my respect for/expectations of/interactions with human beings improve accordingly.
If I believe that human beings are evolved pond scum, my attitudes toward/opinions of/experiences with human beings decline considerably.
