If we remap the entire scale
I have never found a study that confirms this, but I have heard it suggested that the widespread practice of using 75 as the 'center' of a 100 point grading scale in US schools has predisposed the people who attended those schools to center their rating on 75%, rather than on 50%. I feel that the most significant thing FIRST did correctly for this survey question was specifying a center, which I imagine would at least slightly help to fix that bias.
