Some studies suggest IQ scores change minimally and are unreliable in most children, while other studies indicate real changes can occur due to various factors such as brain structure changes, education, and societal influences.
The question of whether IQ scores change over time is a significant topic in the field of psychology and cognitive science. Understanding the stability or variability of IQ scores can have implications for educational strategies, cognitive development, and even socio-economic policies.

IQ as a Volatile Measure:
IQ scores are not entirely stable and can change over time due to various factors. While most children show negligible changes, some experience significant fluctuations. The secular rise in IQ scores, known as the Flynn Effect, indicates that societal and educational changes play a crucial role. In teenagers, IQ changes are linked to brain development, and cross-national differences highlight the impact of education and economic conditions. Therefore, IQ is a dynamic measure influenced by a complex interplay of factors.
