Which of the following is a limitation of group intelligence testing?

• A. Impossible to document the behaviors of an entire group
• B. They consistently yield higher IQs
• C. They require less reading
• D. They provide perfect cultural fairness

Answer: (A)

Group intelligence testing is designed to assess cognitive ability quickly for many individuals at once, offering efficiency and standardization. A fundamental limitation is that it cannot document the behaviors of an entire group from a single administration. The test provides a snapshot of performance, typically yielding a single score, which masks individual differences, growth patterns, and the range of behaviors each person exhibits. Because the setting is standardized and time-limited, you miss how different students approach problems, apply strategies, or respond in real-world situations. This means you can describe general group trends, but you can’t capture a comprehensive picture of every member’s behavioral repertoire or cognitive processes.

The other statements aren’t accurate limitations. Group tests don’t inherently yield higher IQ scores; results can vary and are influenced by many factors. They often require some reading, so claiming they require less reading isn’t consistently true. And they do not provide perfect cultural fairness—biases related to culture, language, and test familiarity can affect performance.
