And for me, that is a tremendous piece of evidence of the direct "impact" that the work has had in the world. Impact on the policies that will shape our lives. Former Columbia University President Bollinger called this "fourth purpose" impact. fourthpurpose.columbia.edu/content/what....

To my fellow researchers - this number is NOT the only way to measure "impact" or "success". But, it's certainly one potential metric. And one thing to think through when we design our next research project or write our next research paper. #measuringsuccess#researchimpact
