The uniformity of the Indus Valley cities also suggests that the people who lived in them had a strong sense of community and cooperation. This is because it would have been difficult to build and maintain such complex cities without the cooperation of all of the people who lived in them. Additionally, the fact that the cities were all built according to a similar plan suggests that the people who lived in them shared a common culture and set of values.
Overall, the uniformity of the Indus Valley cities provides evidence for a centralized and highly organized government, as well as a strong sense of community and cooperation among the people who lived in them.
