See Cheney's interview last night on Lehrer?
No wonder he doesn't do interviews: his lying is becoming more obvious - the downward looks, avoiding questions, carefully-built stories that don't withstand examination.
They are vulnerable to analysis by professionals, even by software
"There exists software today capable of analyzing facial expressions for insincerity.

Professional analysis of facial expressions and body language and movements can help the detection of lies. Inconsistencies in dialogue content also help give away liars.

10% of liars can pass coventional lie detector tests. 20% of those telling the truth typically fail the tests. A more accurate way to judge the truth might be computer analysis of micro-expressions; involuntary facial expressions of a person's real emotions which flash across the face too fast for normal human perceptions to reliably catch. However, such technologies are still in the testing phase as of 1999.

Thermal imaging cameras appear capable of detecting some lies from changes in blood circulation around the eyes.

The old conventional lie detection apparatus (polygraph) may be used to gather certain types of information, but is not itself necessarily an infallible detection device.

Another technology deemed roughly equivalent to the polygraph in accuracy (but which uses a somewhat different method to get its results) is voice stress analysis.

Note that the enormous cost and effort that would be required to integrate all the above techniques and possibly others into a single, extremely accurate lie detection system at any time in the near future could make it impractical and wasteful to use such a system on anyone in society but the very highest ranking and most influential shapers of business and government. |
