Similar to last year, there are two common threads in our methodology. First, in keeping with our goal of rigor, defensibility and reproducibility, we used externally verified, quantitative data (e.g., Web of Science) whenever such data was available and normalized this data where appropriate to add as much nuance into our rankings as possible. When we required qualitative data, we sent out open, public, shareable surveys through all available channels and did our best not to limit participation in any way, constructive or otherwise.
