Music power struggles at gatherings demonstrate the point made in the graphic. Level 1ers are intolerant of stuff outside their preferences, while people with more sophisticated tastes are used to adapting and compromise. Those at the base of the pyramid rule via group think.
People stuck in level 1 indefinitely are usually Pharisees with bland tastes in everything from beer, cocktails, art, food, cultural experiences, etc. People that can hang with stuff level 3 and up are without much exception those I get along with the best.
