Overall, the Flynn Effect highlights significant changes in performance on intelligence tests over time.

Explanation:

The Flynn Effect

The Flynn Effect refers to the observation that scores on intelligence tests worldwide have increased substantially over the past decades. Named after researcher James Flynn, it shows that average IQ scores have risen, approximately by 3 IQ points every 10 years. Several factors have been suggested as explanations for this trend, including:

Better nutrition, leading to healthier brain development.
Increased access to information, providing more learning opportunities.
Greater familiarity with multiple-choice testing, which is commonly used in these assessments.

However, the debate continues regarding whether these increases truly reflect heightened intelligence or are simply a product of improved testing environments and educational systems. Most of the gains were observed during the second half of the 20th century, and some recent studies indicate a potential reversal of the Flynn Effect in certain locations.
