Klaus Stüllenberg and Susanne Stubbe conducted a recent polygraph study for the German Foundation for Crime Prevention (Stiftung Kriminalpraevention). Their key conclusions are:

• A trained subject can manipulate the results of a Polygraph test even when administered by an experienced examiner.
  
  
• Polygraph tests can no longer be used as an indication of truth.
  
  
• Polygraph tests can divert legal processes because they are not accurate.
  
  
• Judicial systems and law enforcement administrations should no longer accept the results of polygraph tests as any indication of truth by the individual being examined.
  
  
• All polygraph testing for legal and criminal purposes should be repudiated immediately on a worldwide basis until further scientific research can verify the findings of the German Foundation for Crime Prevention.

The researchers also note:

Quote:

The APA (American Polygraph Association) has been contacted by the researchers in order to discuss these controversial results but the APA terminated communication and rejected the possibility that the results of a polygraph test could be manipulated with training.

George,

My German is not great but PROSLT(cheers) to you for discovering such an interesting research project done on the polygraph.

It is also to par that the American Polygraph Association turned it aside, however I'm sure that they will obtain copies of it for assessment and not so casual degradation of the research.

I hope that this valuable information is forwarded through to the Senate Judiciary Committee and that they read it

Keep up the great work George!!!!
