It appears to be because the relatively unambiguous nature of the correct answers on tests.
well, that is true and then it is not true too
My most recent exam the raw scores ranged from 17% to 95%. I then applied a proportional curve (the grades farthest from the best score get the most upward adjustment) so that the range was from the mid 50% to 100%, mean in the low 80%.
of course, did you try to explain the logic behind the curving method?? what if you were a student who got 89 ... compared to the one who got 17 ... ? the one who got 17 you boosted by 33% points ... whereas the one who got 89 ... maybe went up by a couple? i think the one with 89 could cry foul ...
and, also ... whether students really like this or not will depend whether the CUT scores for F, D, etc. ... stay fixed ...
if the F point (say) was less than 65 ... the fact that the student who got 17% was moved to 50% ... still fails that student ... so, i don't think if i were that student ... i will be all that thrilled with the test score adjustment
The students loved the curve!
