This is one I kind of struggle with. It's a fact that people in a given generation tend to have the same world view. By knowing what that tendency is can help you when starting to approach someone. However, it is just a tendency so not everyone in a generation is going to hold to those views and you need to actually pay attention to them as people so you can recognize when that's happening. Likewise, people in another generation (either older or newer) may have the world view that tends to belong to a different generation. By knowing the predominant ways of looking at things that people have can help with how to deal with people in general but it's important to know that it's a tendency, not a rule.
