Polygraphs don't really do much IMO. It just reads your bodys pysiological reaction to questions (blood pressure, pulse, etc).

If your really aprehensive about a question, your body could have the same reaction regardless of what the truth is.

I've said it before. I have taken a polygraph test, been telling the absolute truth, and "failed" it. I place NO faith in those things now.

:stupid: Maybe the fact that I stood up ( with wires attached ) and Yelled at him "stop this type of questions or I am going to rip you F***ing head off .! " may of had something to do with it.

So if we can establish that pretty much all the TDF riders are dopers (which to the casual observer appears to be the case), can't we still state that Landis is still the best? I mean it seems like a pretty level playing field to me.

USA USA USA!

I've taken a polygraph before for my job and they are absolute bull. Because you are under so much stress because you don't want the poly graph to accidentally think yer lying that your mind just wanders all over the place. Polygraphs mean NOTHING.

Extensive scientific research has proven polygraphs are a useless tool for a long time now, why do people still use/trust them?

Conclusions and Recommendations

We have reviewed the scientific evidence on the polygraph with the goal of assessing its validity for security uses, especially those involving the screening of substantial numbers of government employees. Overall, the evidence is scanty and scientifically weak. Our conclusions are necessarily based on the far from satisfactory body of evidence on polygraph accuracy, as well as basic knowledge about the physiological responses the polygraph measures. We separately present our conclusions about scientific knowledge on the validity of polygraph and other techniques of detecting deception, about policy for employee security screening in the context of the U.S. Department of Energy (DOE) laboratories, and about the future of detection and deterrence of deception, including a recommendation for research.

SCIENTIFIC KNOWLEDGE
Basic Science

Polygraph Accuracy Almost a century of research in scientific psychology and physiology provides little basis for the expectation that a polygraph test could have extremely high accuracy. The physiological responses measured by the polygraph are not uniquely related to deception. That is, the responses measured by the polygraph do not all reflect a single underlying process: a variety of psychological and physiological processes, including some that can be consciously controlled, can affect polygraph measures and test
