In what ways have psychology’s forerunners and contemporary psychologists come t

•   Forerunners of modern psychology often had insights and made observations that were verified by later work.
•   For example, Hippocrates inferred that the brain is the source of our emotions, Stoic philosophers observed that people become angry or sad not because of actual events but because of their explanations of them, and John Locke argued that the mind works by associating ideas arising from experience.
•   Forerunners of modern psychology also blundered because they relied on anecdotes and casual observations, rather than empirical evidence.
•   Phrenology is an example of such a blunder.
