When we started telling people about our "nutrition label for the news" project, one question came up fairly frequently: “Do nutrition labels even work?”
Of course, when people ask if labels work, they implicitly mean, "Have nutritional labels prevented America from growing more obese each year?" In this case, the obvious answer is “No.”
This doesn't mean that labels don't serve their purpose, or that we don't need them to get healthier. Your political identity is shaped by many things other than where you get your news: your parents, your siblings, your childhood, your education, your workplace, or hey, maybe even your most basic morals or the type of bacteria in your belly.
