Dr. Al Zelicoff, a senior scientist at Sandia National Laboratories, made a cogent observation on the conclusions of the NAS report. He is quoted an article published in the 18 October 2002 issue of Sandia's Lab News publication (emphasis added):

"In consensus scientific statements, it doesn't get any clearer: polygraphs are not worthless, they are worse than worthless, and it is deeply gratifying as well that the Academy echoed the conclusions of the 1999 Sandia Senior Scientists' report on polygraphs."
