Thanks for your input, but I have never heard of this.

A closer look at the Federal Polygraph Handbook reveals the following:

"The following opinions are those that may be rendered when sufficient test data is collected during a PDD examination: deception indicated (DI), significant responses (SR), no deception indicated (NDI), no significant responses (NSR), no opinion (NO)."

Notice that there is no "Inconclusive" and the "No Opinion" is used when there IS sufficient data, which conflicts with your post.

Further scrutiny shows:

"Administrative Opinions. These opinions reflect the results of a series or an examination that are not based upon physiological responses to the applied stimuli such as when the examinee terminates an examination or is practicing countermeasures. In such instances, administrative opinions such as inconclusive, purposeful non-cooperation, etc., are appropriate."

also:

"C8.5.4.3. No Opinion. If it is not DI or NDI, it is NO with the exception of administrative opinions."

So, has the rest of the polygraph community added their own definitions which are in conflict with the Feds? When did this happen? Who did it and where is it documented?
