The Defense Counterintelligence and Security Agency (DCSA) wants to modernize the polygraph. Inside Defense reports that the agency is asking for proposals on “Polygraph Next,” a polygraph that uses artificial intelligence.
People are already split on the idea. Critics say combining AI with the polygraph gives you the worst of both worlds. Supporters point out that the modern polygraph is more than the machine itself. They say machine learning and data analytics could improve how screening is done.
The announcement also stands out because DCSA is the customer. Polygraphs have mostly belonged to the intelligence community, which values them less for catching lies than for making candidates nervous enough to share things they left off their clearance applications. Now there’s growing interest across the Department of War, both for insider threat concerns, such as recent leaks from the Joint Staff, and for wider use in personnel vetting.
The biggest challenge is scale. The traditional polygraph is old technology and takes a lot of time. An AI tool might draw on biometrics, facial analysis, or physical signs like sweating, and it could produce data that scales in a way a one-on-one exam can’t. How the technology would actually work is still unclear. This is an early request meant to bring in solicitations and industry input.
The move fits the vision of DCSA 2.0: more technology and closer work with industry. Former DCSA Director David Cattler once said he didn’t want “laser dolphins,” but an AI polygraph comes close.
Funding still needs approval from Congress, so this change won’t happen right away. Still, it suggests polygraphs could play a bigger role at DCSA than they have before. For cleared professionals, the question is whether AI-driven polygraph screening will become a standard part of personnel vetting. Expect more solicitations, testing, and debate before we find out.
