More than fifty years after the end of World War II, a new chapter of Holocaust history is unfolding. Evidence is emerging of the complicated financial transactions between the Nazis and the European countries and businesses that profited by the genocide.
People with IQ's of 80-90 are a little on the slow side but may be found in fast-food restaurants, day-care centers, etc. They may also be found in unskilled jobs. About 16% of the population has IQ's in this range.
An IQ score of 70 or below is considered a low score. Remember, on most standardized tests of intelligence, the average score is set at 100. Anything over 140 is considered high or genius-level. Sixty-eight percent of all scores fall within plus or minus 15 points of the mean (so between 85 and 115). So what does it mean to have a score 70 or below? In the past, an IQ score below 70 was considered a benchmark for mental retardation, an intellectual disability characterized by significant cognitive impairments. Today, however, IQ scores alone are not used to diagnose intellectual disability. Instead, the criteria for a diagnosis includes an IQ below 70, evidence that these cognitive limitations existed before the age of 18 and limitations in two or more adaptive areas such as communication and self-help skills.
