Fair Chance
You seem like a reasonable person, so here's the problem. Your thought about background investigations solving most hidden employee issues is just not true, Im sorry to say. Just this year our department had applicants admit ( after failing a polygraph) to an agg. battery, felony fraud, sodomy of a child, and of course drastically different drug use histories than placed in the application for hire. We in contrast to the federal govt, do a background first. Many of course fail for various suitability reasons, but if an individual is from another state, or thier violations are dated, a background will just not find it in many cases. This was a common thread in the individuals having the histories I mentioned.
So if we followed the thinking as put forth here, we would have to take our chances in putting our limited resources in a background and calling the process over. I suggest to you that that approach would of enabled several people that should never even come close to the uniform to be armed and go to work. I have no hope that our psychologist would of been able to do more than the background investigators. Does anyone have any good faith suggestions for the real world scenario that I am giving here? (please dont tell me to hire new fully competent background investigators, all are retired Det's with 20+ years experience) If your wondering how many good candidates we falsely turned away, let me say now that all DI charts (this year) were supported by confessions/explanations and then sent back out to background. Someone explain to me without rancor how to prevent an unsuitable candidate from being hired if the background can not provide a legal end to the application.
Breeze,
There simply is no reliable way to prevent an ethically unsuitable candidate from being hired if the background investigation fails to turn up disqualifying information. As the National Academy of Sciences has made abundantly clear,
polygraph screening is completely invalid. Nonetheless, so long as people still believe that the polygraph can detect lies, polygraph screening can have some utility as a means of obtaining admissions that might not otherwise be made, as illustrated in the cases you cited. Considering that polygraph screening itself is without validity, and that some unknown number of deceptive persons can be expected to pass, it is likely that your agency's polygraphers would obtain even more disqualifying admissions if they were to routinely accuse
all examinees of deception and to follow up with a full-blown "post-test" interrogation, regardless of how the charts are scored. However, this bluffery cannot go on indefinitely. As more and more people discover "the lie behind the lie detector" (i.e., that polygraph "testing" is a fraud), polygraph-induced admissions will inevitably dry up.
I think that your agency's use of polygraph screening only
after a background investigation has been completed is commendable. Also commendable is your agency's practice of videotaping all polygraph examinations, which you mentioned in a separate post.
With regard to "good candidates being falsely turned away" you note that "all DI charts (this year) were supported by confessions/explanations and then sent back out to background." It is not surprising that there were confessions or explanations associated with all DI ("deception indicated") polygraph charts. Polygraphers routinely ask those who "fail" what they were thinking of when answering one or more questions. So, even where no confession is obtained, there is at least an "explanation."
A better way to assess the extent to which your agency may be falsely accusing the innocent and denying them employment based on polygraph chart readings is to candidly answer the following questions:
1) What percentage of applicants polygraphed "fail?"
2) What percentage of those who "fail" make no disqualifying admission(s) and are referred for further background investigation?
3) What percentage of these are ultimately hired?
4) Is passing a polygraph "test" a requirement for employment, either de jure or de facto?
