Even if the public at large knows little about polygraphy (just as it knows little about cryptology), it is not safe to suppose that these matters are unknown to foreign intelligence services.

Of course foreign intelligence services know about polygraph technology and procedures.  In some cases, they have gone through schools here in America.  In others, American schools have held courses overseas for a variety of governments and their police and intelligence services.  In most of the many cases of which I am aware, the intelligence services have been those of countries which are our friends and allies, or which pose no realistic threat to us.  In a number of cases, they are using the polygraph to help protect the intelligence which we share with them.

On the other hand, information posted on the Internet can be accessed by every intelligence service in the world, including those who would do us the greatest harm possible.  Instead of having to devote a great deal of manpower and money to acquire knowledge of our security screening programs and procedures and how to circumvent them, you would present them with all that information, and keep them updated on all changes that occur.  And you want me to cooperate in this endeavor??

In another post, you pointed out that a couple of decades ago Ray Weir and Norman Ansley published details of the R/I test.  You cited this to suggest either I or the Government were being hypocritical or disingenous at not discussing it now.  

Times change.  Administrations change.  Personnel change.  Policies change.  Polygraph testing evolves.  Formats and procedures are modified.  Countermeasures are employed, and counter-countermeasures are developed.  Do you think that just because some details were published more than a quarter century ago, the Government ought to keep you (and hence every intelligence service worldwide) updated on every change as it occurs?

Peace,

Gordon
