In the past, some people believed that measuring the skull could reveal insights about intelligence and character. They thought that different areas of the brain controlled specific traits, and that the size of those areas could be determined by the shape of the skull.
Craniology Claim |
Modern Understanding |
Skull shape determines intelligence |
Intelligence is complex and not determined by skull shape |
Bumps on the skull indicate personality traits |
Skull protuberances do not correlate with personality |
Measuring the skull can diagnose mental abilities and disabilities |
Learning challenges are assessed through tests of actual skills and performance |
Today, we know that these claims are not scientifically valid. Skull shape is determined by genetics and has no bearing on mental abilities. Modern methods for assessing intelligence and learning challenges focus on evaluating actual skills and providing needed support.
