Meta-Categories for Inter-Disciplinary Collaboration

For people from different disciplines it's hard to understand each other. Using labels as categories would help understand what the other person is talking about in a second.

So, what are those meta-categories that group all human questions?

I suggest:

• Science

• Arts

• Philosophy

• Education

• Economy

• Culture

• Technology

How would you define meta-categories that help diverse people to understand each other's background faster?
