In one of Cory Doctorow's books, the trick to cheat a lie detector is said to be to clench and unclench the anus repeatedly for several minutes (in advance before the test). Purportedly, this agitates the nervous system so the measurements hike up, and on this background your legitimate discomposure will look like smooth sailing. The anus is probably chosen just for the inconspicuousness.
Dunno how true this is and haven't heard of this trick elsewhere, though admittedly I haven't researched the topic. Other techniques in the ‘Little Brother’ books are real, apart from two or three that are doubtful to me.

- Fjolsvith 7y agoIn the US, they use a sensor pad the subject sits on to detect such attempts to modify the results.

- Fjolsvith 7y agoUnfortunately, disrupting the test is the same as failing it. Typically, subjects are expected to pass it to avoid negative consequences. I once went through a polygraph and used my meditative breathing techniques to calm my mind, and failed the test because I was "controlling my breath".
- kevin_thibedeau 7y agoI mostly belly breathe and have little upper chest expansion at rest. This caused some consternation during my test.
- kofejnik 7y agoI was subjected to a polygraph test once, and I successfully misled the operator several times, by slightly biting my tongue (so I was asked, "you show heightened emotional response to X and Y, something you're trying to hide?")
