What’s similar: The Observer (5) is the Protector’s (8) stress point, and the Protector is the Observer’s security point. Both types are curious, value respect and truth, resist control, and become possessive of space and key resources. Observers in security become more engaged, outgoing and expressive of their desires, feelings and anger. Protectors in stress become more retracted, restrained and reflective.
What’s different: In general, Observers are the most retracted, contained and measured of the nine Enneagram types. They tend to conserve their energy, reduce their needs and think before acting. Protectors, by contrast, are the most expansive, expressive and excessive of the nine Enneagram types. They expand energy, directly expressing their desires and anger, and often act before thinking.
