You all follow checklists, right? Your decisions are verified by standard coded procedures, right? In the aviation world we test on at least two basic concepts. Our closed book tests evaluate information that should be able to be recalled immediately, ala in the cockpit. We have public MQFs to study for those. Our open book tests evaluate information that is good to know to perform your job, but not time critical hence open book to find the answer. Pardon my apparent naiveté, but how do these logic rubik cube tests prepare you to do the job? If our aviation exam program has worked well, why don't other operational fields follow suit?
