"Human Brain Size Increases, but IQs Decline: A Modern Paradox"

Studies show that the human brain has grown by 6.6% since the 1930s, potentially due to external factors like health, education, and culture, and this growth may reduce the risk of age-related dementia. However, despite larger brain sizes, recent generations, such as Gen Z and Alpha, have shown lower IQ scores, possibly linked to increased phone and internet usage. While larger brain size may not directly correlate with intelligence, it could contribute to better brain health and connectivity. The findings raise questions about cognitive development and the impact of modern technology on IQ levels.
