+1 to everything Walter has said, as well.
I haven't thought about this a lot, but doesn't this apply to everything in
terms of user input? Doesn't this really enter the realm of a basic
guideline, principle, or law for UI? (I remember something like this being
applied to database design.)
Don't make people enter data that they don't care about.
Don't make people enter data that doesn't affect anything.
Carefully evaluate whether people really need to enter data.
If people feel free to enter garbage in a field, should that data
really be asked for?
Aren't there, potentially, corollaries to this? For instance, Always allow
the people entering data to easily correct or remove their data.
