## Summary

The Department of Defense has asked for $30.3 million over the next five years to develop “Polygraph+” – an AI‑driven lie‑detection system that would use machine‑learning scoring algorithms and “standoff sensing” to take physiological readings without contact.  The program, to be run by the Defense Counterintelligence and Security Agency, is intended for employee vetting and insider‑threat detection, though the budget request has not yet been approved by Congress.

Critics warn the effort repeats a long history of unreliable polygraph technology.  Professors Kyri Kotsoglou and Sophie van der Zee note that even with AI, there is no solid ground‑truth for lying, and past attempts at non‑contact deception detection have failed.  The Pentagon has recently increased polygraph use after reports that about 50 Joint Staff officers were tested following media coverage of depleted weapons stockpiles in the Iran war.

## Key points

- DoD budget request seeks $30.3 million for a five‑year AI‑enhanced polygraph program.
- Polygraph+ will be managed by the Defense Counterintelligence and Security Agency for vetting and insider‑threat detection.
- Experts say AI cannot overcome the fundamental unreliability of polygraph technology.

## Why it matters

The proposal shows how the U.S. defense establishment is turning to AI for internal security, raising questions about privacy, accuracy, and the future role of automated lie detection in government hiring.
