No, having a big head does not necessarily mean having a big brain. While head size can vary, it doesn't directly correlate with brain size or intelligence. Brain efficiency and connectivity, rather than size, are more critical factors in determining cognitive abilities. Therefore, intelligence is influenced by a combination of genetic, environmental, and social factors, rather than just the physical size of one's head or brain.
