The issue of whether intelligence is primarily based on genetics or the environment has been extensively researched. Many scientists, researchers, and doctors believe that intelligence derives from genes. On the other hand, there are many scientists, researchers, and doctors who believe that intelligence derives from an individual environment. Then, there are those who believe it is a combination of the two, genetics and environment.
             Throughout the past several years there have been studies shown to prove that genetics is the answer for our intelligence. The researchers that believe it are genes that are responsible for our intelligence maybe correct. The researchers that believe it is strictly environment may also be right. Researchers who believe it are both genetics and environment I mostly think is the correct answer for our intelligence.
             It is difficult to test for either genetics or environment because as of now they can only be measured minimally or not at all by the test that we have today. Scientists have started testing for genetics, environment, and other variables by selecting a different degree of blood relationship.
             In order for researchers to test the genetics part of one's intelligence, their test subjects include identical twins, fraternal twins, and ordinary people.
             According to Herrnstein and Murray, "intelligence was not subject to easy environmental control, but was instead difficult to modify and even in part inherited." They believe that since African Americans as a whole, score lower on IQ tests, there should not be wasted funds trying to help a genetically inferior group. Their book, "The Bell Curve" is a very controversial issue, and has many critics. People criticize Herrnstein and Murray for what they have said, and what they have not said. Before the book was released, Herrnstein died, and left Murray to answer all the questions from all the critics. It mad...
