Question

Even though more than 2.3 percent of people have IQs below the 70 cutoff, only about 1 percent of the population has an intellectual disability. The prevalence of intellectual disability is lower than the prevalence of low IQs because

Answer 1

Answer: The prevalence of intellectual disability is lower than the prevalence of low IQs because:

1. Many people with intellectual disabilities die at a younger age. As an indication of these facts, studies show that twice as many school-age children as preschoolers have intellectual disabilities, but the prevalence rates drop again among adults (Grossman, 1983).

2. IQs cannot be adequately assessed among very young children, who therefore may be omitted from prevalence figures.

3. many adults with low IQs are not considered to have intellectual disabilities because they have adaptive skills.

Answer 2

The reasons that can be defined for the frequency of the intellectual disability is comparatively lower than the existence of lower IQs would be:

• As per the data proposed by Grossman, the majority of individuals suffering from intellectual disabilities undergo an early demise which is the key cause behind the lower prevalence of these cases further in adults and the rate of prevalence fall.
• The other cause is that Intelligence Quotient(IQ) is less probable to measure precisely among the tender kids and therefore, they remain ruled out from the prevalence rates.
• Lastly, a number of adults possessing lower IQs are ignored from being considered due to the possession of better adaptive skills.
