The observed increase in IQ scores over time that leads to the decay of norms is known as the "Flynn effect." It asserts that, as James Flynn first discovered in 1984, the average human Intelligence has risen over time.
Throughout a 46-year period, Flynn had discovered evidence "that samples that were representative of the Americans performed better and better on IQ tests, the cumulative gain equating to a jump in mean IQ of 13.8 points."
This finding suggests that human intelligence has risen over time if IQ testing is considered as a reliable indicator of intelligence.
The Flynn Effect can be explained in a number of different ways. Some potential explanations include, among others:
- Education
- Informational access
- Nutrition and well-being
