Is Blinded Review Enough? How Gendered Outcomes Arise Even Under Anonymous Evaluation

For organizations focused on scientific research and innovation, workforce diversity is a key driver of success. Blinded review is an increasingly popular approach to reducing bias and increasing diversity in the selection of people and projects, yet its effectiveness is not fully understood. We explore the impact of blinded review on gender inclusion in a unique setting: innovative research grant proposals submitted to the Gates Foundation from 2008-2017. Despite blinded review, female applicants receive significantly lower scores, which cannot be explained by reviewer characteristics, proposal topics, or ex-ante measures of applicant quality. By contrast, the gender score gap is no longer significant after controlling for text-based measures of proposals’ titles and descriptions. Specifically, we find strong gender differences in the usage of broad and narrow words, suggesting that differing communication styles are a key driver of the gender score gap. Importantly, the text-based measures that predict higher reviewer scores do not also predict higher ex-post innovative performance. Instead, female applicants exhibit a greater response in follow-on scientific output after an accepted proposal, relative to male applicants. Our results reveal that gender differences in writing and communication are a significant contributor to gender disparities in the evaluation of science and innovation.
