Bell curve for intelligence

The bell curve for intelligence, often represented by the normal distribution, illustrates that most people have average intelligence, with fewer individuals exhibiting very high or very low IQ scores. In this model, the mean IQ is typically set at 100, with about 68% of the population falling within one standard deviation (between 85 and 115). This distribution helps in understanding how intelligence is spread across a population, but it has also faced criticism for oversimplifying the complexities of cognitive abilities and their influences.
