And what would you do if Omega told you that the CEV of just {liberal westerners in your age group} is wildly different from the CEV of humanity? What do you think the right thing to do would be then?

The right thing for me to do is to run CEV on myself, almost by definition. The CEV oracle that I am using to work out my CEV can dereference the dependencies to other CEVs better than I can.
