INSUFFICIENT LEANING

Recorded sources

2 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that trained individuals can beat polygraph tests?

Unclear. Two reference works state that spies trained to beat the polygraph have passed such tests, and one calls the polygraph more a deterrent than a spy-catcher. Neither offers systematic or experimental evidence that trained individuals generally can defeat polygraph tests.
