Which concept historically linked skull shape to personality and is not supported by modern science?

• A. EEG
• B. MRI
• C. PET Scan
• D. Phrenology

Answer: (D)

Phrenology teaches that bumps and shapes on the skull reflect personality and mental abilities. It rose in the 19th century as a method to read character by feeling the skull and matching bumps to supposed faculties. Modern science rejects this idea because there isn’t a reliable, consistent link between skull morphology and personality. The brain itself, its structures, and how it functions determine behavior, not skull contours. People with similar skull shapes can differ greatly in traits, and those with different shapes can share many abilities—undermining any claims that skull form predicts personality. What the body of neuroscience actually uses are real brain-measuring tools. EEG tracks electrical activity of the brain and is useful for understanding timing of neural processes and diagnosing events like seizures. MRI gives detailed images of brain anatomy, showing structure, while PET reveals metabolic activity to study function. These methods advance our understanding of the brain without making unsupported leaps from skull shape to personality.
