What is the Flynn effect?

• A. A trend of decreasing intelligence scores over time
• B. The increase in IQ scores observed over time
• C. A phenomenon related to test biases
• D. A theory about emotional regulation

Answer: (B)

The Flynn effect refers to the observed increase in average IQ scores over generations. Named after the psychologist James R. Flynn, this phenomenon highlights that intelligence test scores have risen significantly in many countries throughout the 20th century. This increase is measured in intelligence quotient (IQ) scores, where the average score is typically set at 100. Research suggests this effect may result from various factors, including improved nutrition, better education, more complex environments, and greater access to information, all of which may enhance cognitive abilities and analytic skills required on IQ tests. Understanding the Flynn effect is crucial in assessing intelligence over time, as it indicates that intelligence is not entirely fixed and can be influenced by environmental changes and societal advancements. This concept encourages ongoing discussion about the implications of measuring intelligence and the factors contributing to these shifts in score averages.
