Anonymizing applications for competitive research resources has been demonstrated to reduce bias against women, early career researchers and other marginalized researchers, specifically for applications to use scientific equipment in the planetary and space science research sector. We conducted a nationwide trial in Australia to evaluate the cross-disciplinary impacts of anonymizing applications for use of scientific equipment. The twofold purpose of the study was to observe the degree and existence of disparities, and to evaluate how anonymizing applications would impact application scores, success rates and resource allocation, based on the gender and career seniority of the lead researcher. The trial involved applications to four Australian research entities that manage access to national scientific facilities. The entities implemented anonymization differently. Entity-specific modelling was carried out, followed by a meta-analysis to assess overall effects. Our evaluation reveals a noteworthy absence of gender and career seniority disparities in application outcomes before the implementation of anonymization measures across most entities. The introduction of anonymization led to improved success rates for early-career researchers, while generally maintaining the existing gender equity landscape, with one entity experiencing improved success rates for women-led applications.The implications of this result extend beyond funding outcomes, which represent only one piece of the puzzle contributing to inequity in STEM research. By enhancing success rates for early career researchers, anonymization may create a positive ripple effect in the career pipeline, diversifying the research pool, and supporting the broader issue of retaining and advancing researchers facing barriers in STEM research. Future research examining cultural, racial, and other biases will be key to refining equity efforts in the STEM research sector.
