Why is phrenology now discredited?

Phrenology, the study of personality traits based on the shape of the skull, is now discredited due to its lack of scientific basis and empirical evidence. Advances in neuroscience have shown that personality and cognitive functions are complex and not localized to specific areas of the skull. Additionally, phrenology often relied on pseudoscientific methods and biased assumptions about race and gender, leading to ethical concerns. Consequently, it is regarded as a flawed and outdated practice in the field of psychology.
