Full Idea
The Swamping Problem is that the value of truth swamps the value of additional features of true beliefs which are only instrumentally related to them. True belief is no more valuable if one adds a feature valuable for getting one to the truth.
Gist of Idea
The value of good means of attaining truth are swamped by the value of the truth itself
