Icebergs, Onions, Trees.
These are all ways to talk about culture.
There is the visible part & the hidden part.
It is multilayered.
I came up with a different way to talk about culture (and of course it involves food)!
In intercultural training, we focus on the hidden part of culture. This is the long-standing part of culture - a nation's values. Sort of like chicken soup.
Visible culture is more like avocado toast - trendy & popular but not always in it for the long haul.
