Full Idea
The veil of ignorance is very effective for making people see beyond their vested interests and goals. And yet it does little to ensure an open scrutiny of local and possibly parochial values.
Clarification
'Parochial' implies narrow-minded
Gist of Idea
The veil of ignorance encourages neutral interests, but not a wider view of values
