In this special section, we?re turning the typical model of journalism on its head -- instead of focusing on what?s broken, we?re taking a look at what Massachusetts gets right. By many measures, we lead the nation in social indicators that have a direct impact on how we live. We wanted to know: How did we get here, what can we learn from our successes, and what can we teach other states? But it?s not all perfect: We also examine areas where Massachusetts can improve.
