Where Do Cultures Come From?
Strong Personalities Dictate
But did you ever stop to wonder where that culture came from or how it started? In most groups, the person in the group who has the strongest personality - the alpha person, exerts the biggest influence on the culture. While it may not be intentional, by sheer force of personality, this person tends to establish the group norms. And as new members join the group, they tend to follow those established norms (or leave the group) and the norms become more and more deeply ingrained.
