In 1976, Edward T. Hall developed the iceberg analogy of culture. The ‘iceberg’ model of culture uses the metaphor of the iceberg to make the complex concept of culture easier to understand.
- Like an iceberg, only the ‘tip’ of culture is visible (observable) to the eye
- while the bulk of what makes up cultural identity is submerged (unobservable).
This framework that can be used to explain the concept of your culture to readers.
If you'd like to know more, the Worldbuilding Magazine did a podcast on The Iceberg Principle (S22 E03) in May 2020.
Update (16 June 2020): a cleaner designed iceberg was published on Reddit, with some changes to the framework.
