To Tell the Truth |
|
| The device that is widely used to detect lies today, the polygraph, is simply too unreliable. It is too inaccurate for the results to be admissible in court cases. A 2002 report by the National Research Council concluded that the polygraph can��셳 distinguish innocent people from guilty ones. In response, the U.S. Department of Energy began relying less on the use of the polygraph to conduct security checks on its employees. |

The Outlook for HDTV |
|
| In the late 1990s, when the first television channels began offering high-definition television, few U.S. households had HDTV sets to receive the signals, and it��셲 no wonder: Shows in high-def were scarce, and the average price of an HDTV set was $3,147. |
