Were children smarter a century ago?

<p>This test is much easier than what my kids did in 8th grade, except Physiology, which they hadn’t been taught. I have studied Psychometrics, and the “average IQ” falls within the normal bell curve: 85-115 is average, 70-85 is below average, 115-130 is above average, under 70 is mentally ■■■■■■■■ and over 130 is gifted. In order for the population to continue to have a normal distribution, the tests have had to become more difficult over time. Therefore, I think the answer is no.</p>
