It's interesting, as I've heard the same reasoning with taxation too. We can have all these sophisticated statistical models, risk models, and so forth; yet what ultimately gets produced is a basic tax bracket step scale that (hopefully) anyone can understand. So is there actually academic research on how to best 'dummy down' complex models for society? Or is it end of day the actuaries, statisticians, and mathematicians tell policy makers their findings and some polysci major just approximates from there?
