A Lie Detector Test (And How To Cheat It)

A Lie Detector Test (And How To Cheat It) July 29, 2009

Here’s how it works:

First, he’s shown true and false statements unrelated to his allegiance in the war: “I am at a computer;” “I am at the tea house.” The task is to press a button identifying the statement as quickly as possible: A for true or L for false. Next he reads statements indicating guilt or innocence: “I am a member of the Taliban,” “I support the American troops,” and again asked to press one key for “guilty” statements and one key for “innocent” statements. Finally the two tasks are mixed: Press A for a true or guilty statement; press L for a false or innocent. Then the associations are reversed: A for true or innocent; L for false or guilty. Reaction times are measured. If he’s truly guilty, then he should react faster to “guilty” statements paired with “true.” If he’s innocent, then he should react faster to “innocent” statements paired with “true.”

But might it be possible to outwit the test?
