Brain size may be related to intelligence from "summary" of IQ and Human Intelligence by Nicholas Mackintosh
The idea that brain size may be linked to intelligence has been a subject of interest for many researchers. It is based on the assumption that a larger brain may have more neural pathways and synapses, allowing for faster and more efficient processing of information. This concept is supported by studies that have found a positive correlation between brain size and measures of cognitive ability. However, it is important to note that brain size alone is not the sole determinant of intelligence. Other factors such as neural connectivity, cortical thickness, and efficiency of neural processing also play a significant role in determining cognitive abilities. In fact, the relationship between brain size and intelligence is complex and multifaceted, involving a combination of genetic, environmental, and developmental facto...
