The phrase 'glib uniformity' has been used in at least a few books. For example, in Political Ideals (1917), Bertrand Russell wrote
The state is justified in insisting that children shall be educated, but it is not justified in forcing their education to proceed on a uniform plan and to be directed to the production of a dead level of glib uniformity.
I'm not sure which dictionary definition of 'glib' is nearest to what was meant by Russell. Did he mean superficial uniformity?
