Pentagon seeks $30 million for AI-powered lie detector

The Pentagon is seeking roughly $30 million over five years to develop Polygraph+, an AI‑enhanced lie‑detector that uses machine‑learning scoring algorithms.
The U.S. Department of Defense has asked Congress for $30.3 million to fund a five‑year research effort on an AI‑enhanced lie‑detector, according to a recent budget request. The initiative, dubbed Polygraph+ or Polygraph Next, will concentrate on developing scoring algorithms that leverage artificial‑intelligence and machine‑learning techniques to interpret physiological data traditionally used in polygraph examinations.
The proposal signals a shift from conventional polygraph methods toward data‑driven analysis, aiming to improve accuracy and reduce human bias. If successful, the technology could be deployed in military interrogations, security clearances and other defense‑related vetting processes, potentially reshaping how the Pentagon assesses credibility. At the same time, the move raises questions about the reliability of AI in high‑stakes truth verification and the ethical implications of automating what has long been a contentious investigative tool.
Stakeholders will be watching whether the funding request clears congressional scrutiny and how quickly prototype systems move from lab to field testing. Further developments may include pilot programs with intelligence or law‑enforcement partners, as well as oversight mechanisms to address privacy and civil‑rights concerns. The trajectory of Polygraph Next will therefore be a barometer for broader government confidence in AI‑based decision‑support tools within national‑security contexts.
