1. Should I retake it?
Tough call. If you don't, it might be interpreted by your current employer as a tacit acknowledgment that the polygraph results were correct, and this could potentially have adverse consequences down the road. Normally, the result of any "re-test" with the FBI is foreordained: the applicant is almost certainly going to fail. The practice of offering re-tests seems to be little more than a bureaucratic charade to create the appearance of fairness while continuing to arbitrarily and capriciously disqualify applicants based on pseudoscience.
However, as a currently serving federal law enforcement officer, you might be shown deference that the typical FBI applicant would not receive. You may have a sporting chance of passing a re-test.
Alternatively, you could decline the re-test at this point and explain that you now understand the polygraph is a sham and have no interest in working for an employer that treats prospective employees so shabbily.
Quote:2. Will it show up in my next 5 year background with my current agency?
You bet your life it will.
Quote:3. If it will show up, what is better/worse? Just the one failed attempt, the possibility of 2 failed attempts, or the possibility of a failure and then a pass?
Again, it's a tough call. To a polygraph-ignorant security clearance adjudicator, two failed attempts will look worse than one. There is a further risk associated with taking a re-test: you could also end up being accused of countermeasure use (whether or not you choose to employ them).
Quote:4. If I pass, should I take the job, or is it too much of a risk I might fail in the future and then get fired (in light of the fact that I am already a federal law enforcement officer)?
While the pre-employment polygraph failure rate is about 50%, the post-employment polygraph screening failure rate is much lower (in the low single digits, I believe).
Quote:5. Even though I don’t know much about them…what countermeasures are the easiest and most effective with the least possibility of being detected?
The available research suggests that mental countermeasures and tongue-biting are about equally effective. I think that mental countermeasures are arguably the hardest to detect. While polygraphers have eyes and might observe an ill-concealed tongue bite, they cannot read minds (even though they pretend otherwise).
Quote:6. How much practice of countermeasure is needed before one is ready to use them in a real-life situation?
In research led by Charles Honts, about half of deceptive subjects passed the polygraph after receiving a maximum of 30 minutes of instruction on countermeasures. Of course, the more practice one can get, the better.
But I suggest that you abandon any thought of using countermeasures. Polygraphers from federal agencies that use the polygraph read this message board daily. The FBI polygraph unit will be looking for a federal LEO employed by an agency that doesn't polygraph applying for an analyst position who is coming for a re-test soon. Odds are, there aren't many, and you may be the only one. In addition, they know that people who are initially accused of deception and offered a re-test are likely to have researched polygraphy. If a person coming for a re-test denies having done such research, he/she is probably more likely to be accused of attempted countermeasure use (whether or not he/she actually uses them).
Should you decide to subject yourself to a re-test, I think it would be best to adopt the "complete honesty" approach. Courteously explain to your polygrapher that you've researched polygraphy and understand its scientific shortcomings. You might print out this message thread, provide it to the polygrapher, and explain that although you contemplated using countermeasures, you decided against it. Hopefully, the FBI polygraph unit will not retaliate against you for your candor.
Whatever choice you make, I wish you all the best.
