renraw,

I agree with polyfool: it appears that your polygraph results were inconclusive. Had you "failed," you would have been directly accused of either deception or withholding information and subjected to a post-test interrogation.

Your situation seems to be different from that of those who have actually "failed" an initial FBI pre-employment polygraph and offered a "re-test." In such situations, applicants almost always "fail" the "re-test," too. But this is not necessarily the case with those who initially have an inconclusive result.

It may be in your best interest to continue with the process. When you report for your follow-up polygraph, it would probably be best to adopt the "complete honesty" approach described in Chapter 4 of The Lie Behind the Lie Detector. The FBI's polygraph unit reads this message board, and they'll be looking out for an applicant with an inconclusive result who reports having last used marijuana nine years ago. If you deny having researched polygraphy, you're likely to be found out.
