You let participants know that they'll receive money for every lie they "get away with" making them feel loss-aversion.

This has been used in psychological studies, but it's effectiveness is proportional to cost of doing the study, so it is expensive to get large datasets.

If the machine could catch people lying for $10 (or $50, or ...) in a double blind study, that would set a quantifiable lower bound for its effectiveness.

I have to disagree. A psychopath will value their freedom more than $10 and will be inclined to react differently.
