Overlay

When we assign or infer an enneagram style, that's not as accurate as when we discern a style in a person.
However, it has some validity; when I coach North Americans I keep in mind the Three characteristics of the countries (US and Canada. I've not coached any Mexicans). No matter what the basic style of someone is, you can see an overlay of cultural characteristics.
For example, regardless of the style, many Americans give me a blank look when I ask them what they have that they didn't work for. Especially if they are politically conservative, they assume they worked for everything they have. They ignore race, gender, health, opportunity, IQ and all sorts of systems that support them - both political and natural.
