Phrenology
Mental faculties and character can be inferred from the shape of the skull because different brain “organs” enlarge the overlying cranium.

Current understanding
Brain functions depend on neural tissue and distributed networks, and skull bumps do not provide a valid map of personality, intelligence, morality, or mental faculties.
Institutional episode
United Kingdom
Phrenology developed organized scientific societies and influenced some British physicians, alienists, educators, and reformers. Its institutional ambitions declined by mid-century even as popular practice continued much longer.
Institutions
- Edinburgh Phrenological Society
- London Phrenological Society
Documented consequences
- Phrenological ideas entered psychiatric and neurological interpretation
- Educational and social-reform arguments were framed around supposed skull-based faculties
- Organized societies gave the doctrine scientific and professional legitimacy
Institutional machinery
Phrenological ideas also circulated among physicians, alienists, educators and reformers, but those diffuse professional networks are not listed here as if they were single institutions. The two named societies are the clearest identifiable institutional carriers in this episode.
