Our society has identified two extremes in intelligence. How are these differences identified?

Answer:

Responses may vary but should include some or all of the following information: The two extremes in intelligence levels that our society has defined are intellectual disability (significantly lower than average intelligence) and giftedness (far above average intelligence). Individual extremes for measures of intelligence are often identified through scores on intelligence tests. Individuals having an IQ above 130 are often labeled as gifted, whereas individuals scoring 70 or lower on an IQ test are often labeled as having an intellectual disability.
