I don't believe that making all distractors "equally bad" is a test writting
criterion. In preparing multiple choice distractors the goal is to create
distractors that are plausible. For example in a quantitative question, the
distractors might be the results obtained by dividing by n rather than (n - 1)
or selecting the incorrect number of degrees of freedom. The question writer
is usually expected to be able to explain why the distractors were chosen.
