In the case of health care, desicatted data does not tell the story of what's occurring on the front lines of care, in the lifes of people or thier doctors.
I would paraphrase the Mae West line to read,“It’s not the data that matters, but how the data is used that matters."
"Take the contentious issue of physician salaries, for instance. Most progressive wonks feel that American doctors are overpaid, and in their ideal world, would like a single payer system where doctors are on a salary in line with the rest of the world. Ezra Klein, for instance, continually points to France to illustrate this point."
