In terms of IQ testing, what would be an example of a question with low predictive validity?

The option related to favorite color serves as a prime example of a question with low predictive validity in the context of IQ testing. Predictive validity refers to the extent to which a test accurately forecasts outcomes it is intended to predict. In this case, the question regarding favorite color does not have a logical relationship with cognitive abilities or intelligence as measured by IQ tests.

Unlike the other options, which relate to measurable skills or knowledge that can tangentially connect to cognitive performance (such as language proficiency, mathematical ability, or IQ scores themselves), a person's favorite color is subjective and largely irrelevant to their cognitive skills. It does not provide any information that would indicate how someone might perform on an IQ test or in intellectual pursuits. Therefore, it exemplifies a question that would yield little to no actionable insight regarding an individual’s intellectual capabilities.
