Polygraph testing for national security screening is little more than junk science, with results so inaccurate that they tend to be counterproductive, according to a long-awaited report released Tuesday by the National Academy of Sciences.

A federal judge has ruled that the results of polygraph tests are still not reliable enough to be admitted as evidence in courts of law. "Polygraphy has not achieved general acceptance in the scientific community for courtroom use," said U.S. District Judge Gary L. Taylor. In ruling against the admissibility of polygraphs, more commonly known as lie detectors, Taylor denied a motion for a new trial filed by a 50-year-old Miami man sentenced to 22 years in federal prison for cocaine possession.

A state Court of Appeal ruled Monday that cities and counties may require applicants for jobs as police officers to submit to polygraph tests about their character and background.

Wired to a polygraph, South Korean lobbyist Tongsun Park was undaunted by charges that he had sought to bribe dozens of congressmen during the so-called Koreagate scandal in the 1970s. Defense lawyer William G. Hundley, sitting alongside Park at his questioning by an FBI polygrapher, marveled at his client's ability to shield lawmakers he considered friends. "The needle never moved," said Hundley, recalling how Park denied payment after payment without the polygraph registering any deception.

Former public relations executive Douglas R. Dowie will not be allowed to introduce the results of a privately administered polygraph test at his upcoming trial on charges of padding bills to the Department of Water and Power, a federal judge has ruled.

Donald P. Gregg, a top aide to George Bush when he was vice president, failed a 1990 FBI polygraph test on his knowledge of the Iran-Contra scandal--evidence that, while not admissible in court, has nevertheless encouraged prosecutors to continue their investigation of his role, sources say. Gregg, now U.S. ambassador to South Korea, has testified repeatedly that he did not know about the efforts of White House aide Oliver L.

The demand to cast an ever-wider net of security across the country has created a rush to embrace technologies that have demonstrated a sometimes staggering propensity for snaring the innocent. Since last year's terrorist attacks on the World Trade Center and the Pentagon, hijackers, spies and snipers are seen as blending invisibly into airports, public buildings and city streets -- even infiltrating the very agencies that guard against attacks.

The CIA has been known to catch spies by strapping them to polygraph machines. The FBI routinely nabs crooks--and clears innocent people--in the same fashion. And if California courts allowed it, jurors in O.J.
