below 70-75, i.e. significantly below average. If a person scores below 70 on a properly administered and scored I.Q. test, he or she is in the bottom 2 percent of the American population10 and meets the first condition necessary to be defined as having mental retardation.

Like most aspects of human behavior and cognition, intelligence is a complex trait that is influenced by both genetic and environmental factors.
The reality is that IQ results are usually fairly accurate. The psychologist conducting the test ensures this by making sure they don't just look at the test score in isolation. If they're working with a child, for example, they might take into account other factors.
