Check your arithmetic. If you are really randomly guessing, then you would
be expected to get one correct answer for each four items on which you
guess. So you randomly guess on four items. On one you get the correct
answer (score = +1), on three you guess wrong (score = -.75). If your
parameters are correct, the advantage goes to the guesser. When I last had
the actual parameters at hand, the expectation worked out to be no change in
expected score for random guessing -- but most guessing is not random, even
if you don't think you have "eliminated" any of the options. Those who do
not guess are doing themselves a disservice, IMHO
