We agree with the author that a quantitative analysis of the predictive nature of the metrics used in graduate student admissions is a worthy pursuit and value the sincere intentions behind the UCSF Tetrad study. However, these types of analyses would benefit from the same rigorous approaches that we employ in our other research endeavors. As UCSF Tetrad graduates with diverse careers in academia, medicine, industry, and publishing, we hope that the definition of success in graduate school can be as thoughtfully and scientifically examined as the measurements used to select the next young people to follow in our footsteps.
