Is there any data, evidence, or reason to believe that a person who receives neurofeedback training could manipulate poly results? Neurofeedback training claims that after training a subject can consciously alter their brainwave activity, as it relates to stress responses, and by extension heartrate and breathing. It would seem that, if this is true, you could ask this person any question you wish, and they could provide the correct stress responses as they chose for each question, or better yet, simply flatline the entire examination.

Little research has been done on this question. However, the late David T. Lykken, at p. 274 of the 2nd edition of A Tremor in the Blood: Uses and Abuses of the Lie Detector writes:

During the 1960s, my university accepted a secret research contract from the Air Force to study the effectiveness of countermeasures against lie detection. My job in this project was to train the experimental subjects. They practiced controlling their responses to my questions while observing their own reactions on the polygraph—the technique now known as "biofeedback." When I thought they were prepared, I would send them on to the chief of our university police department, a polygraph examiner of long experience, who would administer a formal lie test. This work had just gotten well under way when a new university president cancelled all secret research contracts, including ours. (I never understood why the Air Force insisted o the "secret" classification, since the only thing about our project that could really be kept secret was the source of the funding.) But we had gone far enough by then to convince me that some people could learn to attenuate their relevant responses and beat the lie detector in that fashion—but that it is very difficult for most people and probably impossible for many.

This seems worth some looking into. The technology is quite farther advanced. These devices are available for under 300 dollars that show brainwave activity, heart rate, breathing, and show in real time what is happening in response to stimulus. These companies have a business built around doing just what this researcher was talking about although for anxiety control not polygraph control. And the polygraph basically reads anxiety if I'm not mistaken. Some of these devices work off an app with a teacher reading results and doing the training remotely. I have no idea if this is true, but there are many psychiatrists now offering this type of training. I wonder if the benefits could cross over. At the very least it could help avoid the false positives that we are concerned about here by calming down the examinee.
