A new report shows that more than 10,000 workers with doctorates in science, technology, engineering, and mathematics (STEM) have left federal service since 2017. This 'brain drain' of top technical talent is raising concerns about the government's ability to maintain complex infrastructure, fund long-term research, and respond to critical challenges, as the most skilled workers are leaving for better opportunities in the private sector.

Why it matters

The government plays a unique role in funding high-risk, long-term research and managing critical public infrastructure that the private sector cannot or will not take on. The loss of experienced STEM experts with deep institutional knowledge threatens the government's capacity to tackle complex technical problems, from maintaining aging nuclear facilities to debugging spacecraft systems millions of miles from Earth.

The details

The report highlights the case of NASA's Voyager 1 spacecraft, where engineers had to reverse-engineer 40-year-old code and devise innovative workarounds to fix a technical issue, drawing on decades of accumulated expertise. However, this type of highly specialized knowledge is rapidly dwindling as STEM Ph.D.s leave federal service, often not to retire but to seek better working conditions in the private sector.

  • In November 2023, NASA's Voyager 1 spacecraft started sending garbled signals back to mission control.
  • Since 2017, more than 10,000 workers with STEM doctorates have left federal service.

What they’re saying

“The people doing this work aren't interchangeable bureaucrats. They're often among the most skilled people in their fields, choosing government service because the problems are uniquely challenging and because they want to serve the public (like my father, who left a more lucrative private sector career to give back to the country that welcomed him as an immigrant from India).”

What’s next

The government will need to take steps to retain and attract top STEM talent, such as improving working conditions, increasing compensation, and providing more opportunities for career advancement and professional development.

The takeaway

The brain drain of highly skilled STEM experts from the federal government poses a serious threat to the country's long-term innovation capacity and ability to maintain critical infrastructure. Addressing this issue will require a concerted effort to make government service more attractive and rewarding for the nation's top technical talent.
