This is yet another generalization that doesn't hold true for the vast majority of the couples that I am aware of.
(scope = me) != (scope = the world)
Your bubble is unique to you, even if it seems like that's the whole world because you haven't seen much outside of your bubble (almost by definition) that does not mean that you are going to be able to generalize outside of your bubble from data collected inside of it except for the most obvious of cases.
This statement is indicative of living in a bubble but being unaware that it exists.
