As a veteran journalist at the Boston Globe, Adam Pertman had it made. At 48, with 20 plus years experience and several major awards to his credit, Pertman could pretty much pick and choose his assignments. And so he wore a variety of journalistic hats, ranging from California Bureau chief to restaurant reviewer. In each capacity, Pertman made it his mandate to write with clarity and accuracy and by all measures, he did so successfully. He did not seek to fundamentally alter the way that people think. At least not until recently. Then things changed.
