The NSA is working on a computer system that can predict what people are thinking.

[...]

It sounds like something right out of science fiction — a system that can literally read thoughts like a magician.

It’s called “Aquaint” (Advanced QUestion Answering for INTelligence), and PBS’s James Bamford takes a stab at explaining how it works:

“GETTING AQUAINT

Known as Aquaint, which stands for “Advanced QUestion Answering for INTelligence,” the project was run for many years by John Prange, an NSA scientist at the Advanced Research and Development Activity. Headquartered in Room 12A69 in the NSA’s Research and Engineering Building at 1 National Business Park, ARDA was set up by the agency to serve as a sort of intelligence community DARPA, the place where former Reagan national security advisor John Poindexter’s infamous Total Information Awareness project was born. [Editor's note: TIA was a short-lived project founded in 2002 to apply information technology to counter terrorist and other threats to national security.] Later named the Disruptive Technology Office, ARDA has now morphed into the Intelligence Advanced Research Projects Activity (IARPA).

A sort of national laboratory for eavesdropping and other spycraft, IARPA will move into its new 120,000-square-foot home in 2009. The building will be part of the new M Square Research Park in College Park, Maryland. A mammoth two million-square-foot, 128-acre complex, it is operated in collaboration with the University of Maryland. “Their budget is classified, but I understand it’s very well funded,” said Brian Darmody, the University of Maryland’s assistant vice president of research and economic development, referring to IARPA. “They’ll be in their own building here, and they’re going to grow. Their mission is expanding.”

If IARPA is the spy world’s DARPA, Aquaint may be the reincarnation of Poindexter’s TIA. After a briefing by NSA Director Michael Hayden, Vice President Dick Cheney, and CIA Director George Tenet of some of the NSA’s data mining programs in July 2003, Senator Jay Rockefeller IV, the vice chairman of the Senate Intelligence Committee, wrote a concerned letter to Cheney. “As I reflected on the meeting today,” he said, “John Poindexter’s TIA project sprung to mind, exacerbating my concern regarding the direction the administration is moving with regard to security, technology, and surveillance.”"
