Final answer:
The original formula for IQ might not be accurate for individuals across different age groups due to the assumption of consistent intellectual development. IQ tests have been scrutinized for potential biases affecting those from varying socioeconomic backgrounds and individuals with learning disabilities. There is a debate about how to effectively measure intelligence and the validity of current IQ testing methods.
Step-by-step explanation:
The most realistic and reasonable concern about the original formula for calculating a person's intelligence quotient, which is MA/CA × 100, is c) It may not be accurate for individuals of different age groups. This formula relies on the assumption that intelligence develops at a consistent rate across all ages, which is not always true.
Historically, intelligence quotient (IQ) tests have faced numerous criticisms regarding their validity and fairness. Conflict theorists argue that IQ tests are biased, as they might not give children with different types of learning disabilities a fair chance to demonstrate their true intelligence. Furthermore, environmental factors such as socioeconomic status can impact IQ scores. Children living in poverty, for instance, can exhibit reduced cognitive functions, influencing their scores. These findings suggest that IQ tests might inadvertently penalize individuals from certain social and economic backgrounds or those with particular disabilities.
When measuring intelligence, it's important to recognize that there are multiple facets to consider besides academic abilities. There is an ongoing debate about what specific skills should be assessed in IQ testing. The validity of such tests is an issue of debate in the field of psychology. Thus, when IQ tests fail to take into account the complex nature of intelligence and its development, their accuracy as a measure of an individual's capabilities can be questioned.
