A phrenologist was someone who practiced phrenology, a pseudoscience claiming that skull shape reveals personality traits and mental abilities. This theory is now discredited, it was once taken seriously. They would examine bumps and contours on a person's head to "read" their character. Imagine them as fortune tellers 🔮, but using your skull as a crystal ball. It was like an early attempt at personality assessment. Today, it is considered a historical curiosity with no scientific basis.
