Arno's Hypothesis

Arno's Hypothesis suggests that certain physical traits, such as head shape or facial features, might be linked to cognitive abilities or intelligence. It is based on the idea that physical characteristics could reflect underlying brain structure or function. Historically, some believed that measuring skull features could provide insights into mental capacity. However, modern science has largely discredited this hypothesis, recognizing that intelligence is complex and influenced by many factors beyond physical appearance. The hypothesis serves as an early attempt to connect physical characteristics with psychological traits, emphasizing the importance of scientific rigor and avoiding oversimplifications of human diversity.
