I've also heard of
A. Something was wrong
B. Good job—met expectations
C. Something was unusually good
Sort of like ride-share "give a complement" feature, since they know everyone gives 5 stars.
Another option (that I've never seen) is to tell the rater their response will be weighted based on their previous scores. So if someone who always gives 5 stars gives a 4 star, it's interpreted as a negative response. But if someone who gives majority 3 star reviews gives a 4 it's interpreted as positive.
