By this I mean, organize around some single person for leadership, or in other contexts focus on a popular figure. Even societies that tend to be described as more collectively-organized/oriented tend to do this.
People are people and are as flawed as one another, so this pervasive tendency to elevate others is odd to me. It can be fun and goofy as a game, but as a more serious organizing or focal principle, it just seems extremely fragile and prone to failure (e.g. numerous groups falling into disarray at the loss of a leader/leader & their family, corruption via nepotism and the like, etc.).
Because it’s easier than going on your own
For sure. Humans are super social and our big brains enable so much verbal, nonverbal, and written communication that we became more efficient as a group. All the greatest things out there, bridges and sky scrapers and roads were built by teams, not an individual, because of our strong communication skills.
