This study was sponsored by the Office of the Executive Director for Force Resiliency within the Office of the Under Secretary of Defense for Personnel and Readiness to address two taskings from the FY 2020 National Defense Authorization Act (NDAA):
- Establish criteria for determining when to review data indicating that racial, ethnic, and gender (REG) disparities in military justice outcomes may exist and provide guidance for how to conduct that review.
- Conduct an evaluation to identify the causes of identified REG disparities and take steps to address them.
To address the first tasking, the study team combined emerging best practices from the civilian criminal justice system (CCJS) with a review of the military justice system (MJS) to create guidance for data collection, analysis, and reporting that will allow the services to use administrative data to conduct ongoing assessments of how members of all REG groups are treated within the MJS. To address the second tasking, the team used multivariate statistical techniques to analyze available data with the goal of measuring REG disparities in MJS outcomes, holding constant other relevant factors. This report addresses the first tasking; the second tasking is addressed in a companion report titled, Exploring Racial, Ethnic, and Gender Disparities in the Military Justice System.
To guide our approach to addressing the NDAA tasking, we drew on four concepts related to justice and bias and considered their implications for data collection and analysis.
Distributive versus procedural justice
Distributive justice relates to the distribution of outcomes within a community. In the MJS context, distributive justice relates directly to REG outcome disparities and suggests that the services should collect data to determine whether people who are the same except for their REG characteristics experience the same MJS outcomes. Procedural justice relates to the system that generates the outcomes. Procedural justice is defined in terms of the rules of the system and the extent to which they are applied consistently and impartially and communicated clearly. To assess procedural justice in the MJS, it is necessary to collect and analyze data on underlying processes, not just final outcomes. It is possible for procedural injustices to occur without generating outcome disparities, and it is possible for a system to be procedurally fair but to generate different outcomes for members of different REG groups. Thus, on their own, average outcome disparities are not complete indicators of bias.
Individual versus institutional bias
Generally, bias is defined as prejudice for or against one person or group of people, especially in a way considered to be unfair. To cause MJS outcome disparities, such prejudices must be turned into biased actions, which can occur at the individual or institutional level. In the context of the MJS, individual bias is exercised by individual actors within the system through their individual decision-making discretion. It can be both explicit and implicit. Because individual bias is exercised through discretionary decision-making, finding evidence of it in data calls for identifying places in the system where individual discretion matters most to see if this is where disparities occur. Institutional bias is present when the policies, procedures, and practices that define a system consistently create positive or negative outcomes based an individual’s REG status. It can be intentional or unintentional. To identify the presence of institutional bias in the MJS, it is necessary to collect and analyze data that reflect outcomes that are guided by regulation or policy.
Concerns about bias in the MJS
Bias in the MJS—both real and perceived—can decrease the effectiveness of the MJS and thereby degrade good order and discipline and reduce warfighting readiness. There are widespread and persistent perceptions that the MJS is biased, and these perceptions exist both inside the military, especially among members of color, and outside the military, among the American public and members of Congress.
The broader social context in which concerns about bias are formed matters. Although the services have their own justice system and control over how that system is implemented, their members are drawn from the American population and public support is necessary for continued recruiting and funding. Thus, concerns about REG bias in the MJS will ebb and flow as they ebb and flow in the national culture and they may arise from within or without.
The quality and presentation of data and data analysis also matter. Over the years, analyses of MJS data have done little to alleviate concerns about bias. Given the persistence of these concerns, it makes sense to create a robust system for data collection, rigorous analysis, and appropriate reporting to enable detailed assessments of MJS outcomes and the policies and practices that produce them.
To identify points in the MJS where institutions and individuals apply discretion, as well as important MJS outcomes to study, we created a chart that maps how a case flows through four phases of the MJS—incident processing, pre-trial/pre-hearing, adjudication and sentencing, and post-trial/post-hearing—and identified key steps in each phase.
A main source of institutional discretion in the MJS lies outside the system. Given that servicemembers can enter the system if they are accused of disobeying a regulation, institutional choices about the nature and design of regulations will affect MJS outcomes. Individual discretion is more likely to be applied within the MJS, at different points by different actors. The most individual discretion rests with commanding officers during the incident processing phase and, in later phases, along the disciplinary path and the summary court-martial branch of the judicial path. Once a case is referred to special or general court-martial, discretion is spread across more people. Actors with significant discretionary power on the judicial path include convening authorities, who are military commanders with little or no legal training, and judge advocates, who are legal professionals serving as military judges and trial and defense counsels.
As a whole, the flowchart highlights the importance of considering the full range of outcomes because movement through the system is determined by the outcome at each successive step along the relevant path. The steps within each phase identify the important outcomes.
Addressing MJS bias with administrative data
The primary benefit of using administrative data to measure REG disparities in MJS outcomes is that it creates an evidence-based picture of MJS outcomes that distinguishes between isolated incidents and widespread problems. To generate meaningful measures of these disparities, it is necessary to use multivariate analytical techniques that allow researchers to measure REG outcome disparities while accounting for other factors that affect MJS outcomes. The more relevant other factors that can be included in the model, the more likely it is to hold “all else” equal. If REG disparities still exist after accounting for other factors, it is likely that the outcome differences are directly related to REG. Such a finding does not prove that bias exists, but it takes the other factors off the table. The multivariate techniques we identified range in technical sophistication and resource requirements. Disaggregating raw data by multiple outcomes and factors is the easiest of the four approaches we identified, and it can be done by agency staff. While not as conclusive as approaches that control for multiple factors simultaneously, disaggregation provides a more complete picture than bivariate analysis and helps agency staff make informed decisions about where to focus more technical analyses and scarce analytical resources. Used together and on a regular basis, disaggregation and the more complicated approaches provide the basis for ongoing monitoring of REG outcomes to identify and address disparities before they become persistent or systemic. Existing MJS and other reporting requirements provide a natural schedule for conducting assessments and reporting their results.
Application of valid multivariate techniques requires detailed data. Current Department of Defense guidance directs the services to collect nearly all the desired data elements, so if the guidance is implemented, they should be well positioned to conduct meaningful assessments of MJS outcomes. There are two caveats to this conclusion. First, there may be gaps for information on investigations and disciplinary outcomes. Second, the services may not have the resources to implement the data collection guidance. It may be an unfunded mandate.
Finally, the tasking from the FY 2020 NDAA asked for criteria to determine when to further review data indicating that REG disparities in MJS outcomes may exist. There is no scientific or social consensus about which criterion to use or what level of disparity equates to bias. Therefore, the services should work with internal and external stakeholders to select multiple criteria based on the absolute size of a disparity, its statistical significance, and the number of people it affects.
Recommendations to address the NDAA tasking
We recommend that the services do not conduct detailed assessments of MJS data only in response to disparities measured by bivariate metrics. Instead, assessments should be conducted regularly using the blueprint provided by lessons learned from the CCJS:
Step 1. Work with internal and external stakeholders to identify issues of concern, set priorities, and develop decision-making criteria
Step 2. Create an analysis plan based on the concerns and priorities identified in Step 1
Step 3. Collect data on MJS outcomes (including nonjudicial outcomes) and relevant control variables in easy-to-use electronic records management systems and ensure they are regularly updated
Step 4. Execute the analysis plan from Step 2 using appropriate quantitative and/or qualitative methods
Step 5. Regularly and transparently report assessment results to all the stakeholders as appropriate
Step 6. Make policy decisions about how to address REG outcome disparities based on the established priorities and criteriaDownload full report
