To answer the question in the headline: no, polygraph "testing" cannot beat Russian corruption. Polygraphy itself is a fraudulent procedure: it has no scientific basis whatsoever. Worse still, it's inherently biased against the truthful, while clever liars who understand the trickery on which polygraphy relies can easily pass using simple countermeasures. I'm a co-founder of AntiPolygraph.org, a non-profit, public interest website dedicated to exposing and ending waste, fraud, and abuse associated with the use of polygraphs and other purported lie detectors. It is a pity to see Russia repeating America's mistake in embracing the pseudoscience of polygraphy.
