You don't think tradespeople are contientious, intelligent, or productive? That's the whole trouble with this filtering signal. It's bogus and has created elitism around professions that are just as hard if not harder than pushing computer keys.
Would you say all people have the same level of intelligence and conscientiousness? If not, we need _some_ way of saying who is, so that they could be matched to higher complexity jobs. It's far for perfect but it works somewhat
