The National Academy of Sciences was established in 1863 by an Act of Congress, signed by President Lincoln, as a private, nongovernmental institution to advise the nation on issues related to science and technology. Members are elected by their peers for outstanding contributions to research. Dr. Marcia McNutt is president.

The National Academy of Engineering was established in 1964 under the charter of the National Academy of Sciences to bring the practices of engineering to advising the nation. Members are elected by their peers for extraordinary contributions to engineering. Dr. John L. Anderson is president.

The National Academy of Medicine (formerly the Institute of Medicine) was established in 1970 under the charter of the National Academy of Sciences to advise the nation on medical and health issues. Members are elected by their peers for distinguished contributions to medicine and health. Dr. Victor J. Dzau is president.

The three Academies work together as the National Academies of Sciences, Engineering, and Medicine to provide independent, objective analysis and advice to the nation and conduct other activities to solve complex problems and inform public policy decisions. The National Academies also encourage education and research, recognize outstanding contributions to knowledge, and increase public understanding in matters of science, engineering, and medicine.

Preface

It is an honor for me to serve as chair of the National Academies of Sciences, Engineering, and Medicine Roundtable on Black Men and Black Women in Science, Engineering, and Medicine, and serve as the editor of the first in a series of proceedings publications from the Roundtable. Our work began in 2015 when leaders of the W. Montague Cobb/National Medical Association Health Institute and I recognized the growing absence of Black men in medical schools. In fact, levels of Black men entering medical school reached a historic low in 2015 and 2016. Starting in 2016, and with financial support from important partners such as the Aetna Foundation, the Burroughs Wellcome Fund, the Robert Wood Johnson Foundation, and the Connecticut Black and Puerto Rican Legislative Caucus, we began planning a National Academies workshop on issues surrounding the absence of Black men in medicine. The joint workshop entitled “The Growing Absence of Black Men in Medicine and Science” took place in 2017. It was historic, in that to my knowledge it was the first National Academies activity specifically focused on issues involving Black people. The proceedings is entitled An American Crisis: The Growing Absence of Black Men in Medicine and Science. It was released in May 2018, and corresponded to a briefing on the subject of Black men and medicine with the Congressional Black Caucus in Washington, D.C. Many of the ideas that emerged from the workshop have been embraced by academia, industry, and philanthropy. More needs to be done.

Our next steps have involved the development of a more permanent presence in the National Academies to discuss issues surrounding Black men and Black women in science, engineering, and medicine. With support from

our anchor partners named above, along with the Johnson & Johnson Company, the W. K. Kellogg Foundation, and the University of Pittsburg, and with the continued leadership and commitment from Dr. Victor Dzau, the president of the National Academy of Medicine, the Roundtable on Black Men and Black Women in Science, Engineering, and Medicine was launched late in 2018. I am grateful to the steering committee members for the Roundtable: Drs. L. D. Britt, Cedric M. Bright, George Q. Daley, Randall C. Morgan Jr., Elizabeth O. Ofili, Vivian W. Pinn, and Louis W. Sullivan.

In September 2021, the Roundtable organized a workshop aimed at exploring psychological factors that contribute to the dearth of Black students in science, engineering, and medicine. From the outset, the goal of the workshop was to gather ideas that might address the systemic and long-term changes needed to allow for success of Black students. The co-chairs for this workshop spent considerable time examining the continuum of systemic issues that affect Black students. The workshop began with discussing Pre-K to 12 education as a fundamental issue for Black students. How does one address foundational effects of a system often broken? Next, a discussion of changes needed at colleges and universities took place. The question was asked: How does one not only assure access and success but also promote well-being? Next, a discussion of other sectors that can influence outcomes was discussed, and finally, an ideas session took place, noting a sense of urgency in moving forward with change. The overall goal of the workshop was to explore innovative ideas that could ultimately become policies to help ensure the success and vitality of Blacks pursuing careers in science, engineering, and medicine in a world fraught with systemic pressures.

I am grateful to the co-chairs of the workshop, Dr. Evelynn M. Hammonds, Dr. Shirley M. Malcom, and Dr. Vivian W. Pinn. This was perhaps the most difficult and controversial subject that the Roundtable has tackled so far. They demonstrated a high level of intellectual expertise combined with a sense of compassion and urgency to the workshop program. This workshop provided a 360-degree view of issues surrounding psychological barriers for Blacks pursuing science, engineering, and medicine. I look forward to seeing follow-on discussions on how the ideas here can be implemented in partnership with multiple sectors, especially education. As with the Roundtable’s previous proceedings, they are meant to move us to action.

Efforts over the last several decades to increase the participation and leadership of Black men and women in the scientific and medical workforce have had limited results. Despite many individual successes, the number of Black professionals in science, engineering, and medicine (SEM) fields has not reached a level that corresponds with African American representation in the country at large. Structural racism affects progress at all stages along the pathway - from young children through graduate and medical students through faculty and clinicians at all levels. Beyond entry into educational programs or recruitment into workplaces seeking to diversify, challenges persist to achieve equity and inclusion for Black males and females. Moreover, psychological barriers confound the engagement of Black men and women in SEM fields.

To explore these issues and suggest solutions, the National Academies of Sciences, Engineering, and Medicine launched the Roundtable on Black Men and Black Women in Science, Engineering, and Medicine. Over the past 2 years, the Roundtable has convened workshops on K-12 education, the impact of COVID-19, financial burdens to pursuing SEM careers, and other topics. Sessions during each of these workshops identified psychological factors related to those specific topics. To have a more targeted discussion, the Roundtable convened a virtual workshop on September 14-15, 2021. As summarized in this proceedings, panelists and participants identified policies and practices that perpetuate these factors and explored solutions toward achieving and maintaining wellness, especially among students and young professionals.
