Did you see me mentioning methods anywhere? If a method can get you closer to truth, then that is its justification. But in the example given the method was "it would make him happy if they won". This is not a reliable method for reaching truth and on average will get you farther from it.
This was copied from here.
Surely it is obvious that there are lots of examples when one might say this. Consider this:
Rob looks in the newspaper to check the football scores. The newspaper says that United won 3-2, but it is a misprint because City actually won 3-2. In this case, the rational belief is that United won, but the true belief is that City won.
Am I missing something?
