Which explanation do you favor for the Flynn effect: that people are getting smarter or that people are merely getting more practice at the skills measured on IQ tests? Defend your opinion. The rise in performance on IQ tests contrasts sharply with a steady decline in performance over the past few decades on many tests that measure factual knowledge, such as the SAT. Think of several possible ways to explain these contrasting results, and form an opinion as to the most likely explanation. Results on IQ tests tend to differ among different ethnic groups.
