How does Human Nature and Conduct develop the theme of Social Psychology as the Study of Collective Habit?

Human Nature and Conduct by John Dewey develops Social Psychology as the Study of Collective Habit across the chapters the companion marks for this theme.

Dewey contends that social psychology should focus on how customs and institutions shape individual minds, not on how individual minds form society, reversing traditional psychological assumptions.

Dewey argues that habit is inherently social, formed through adjustment to environing conditions, especially the activities of others, and that social psychology must abandon the premise of separate, independent minds.
