What could go wrong?

Dr. Stout offered a not-so-modest proposal: along with releasing their tax returns and medical records (and, sometimes, birth certificates), maybe political candidates should be asked to prove their psychological fitness before their names go on the ballot. Though psychopaths can apparently fool even skilled psychiatrists into thinking they're normal, Dr. Stout maintains that standardized psychological tests like the Minnesota Multiphasic Personality Inventory (and someday maybe brain scans) might be able to tip voters off to candidates who exhibit worrisome personality traits.
