<p>The polygraph, often portrayed as a magic mind-reading machine, is still controversial among experts, who continue heated debates about its validity as a lie-detecting device. As the nation takes a fresh look at ways to enhance its security, can the polygraph be considered a useful tool?</p>
<p><i>The Polygraph and Lie Detection</i> puts the polygraph itself to the test, reviewing and analyzing data about its use in criminal investigation, employment screening, and counter-intelligence.</p>
<p>The book looks at:</p>
<ul>
<li>The theory of how the polygraph works and evidence about how deceptiveness?and other psychological conditions?affect the physiological responses that the polygraph measures.</li>
<li>Empirical evidence on the performance of the polygraph and the success of subjects' countermeasures.</li>
<li>The actual use of the polygraph in the arena of national security, including its role in deterring threats to security.</li>
</ul>
<p>The book addresses the difficulties of measuring polygraph accuracy, the usefulness of the technique for aiding interrogation and for deterrence, and includes potential alternatives?such as voice-stress analysis and brain measurement techniques.</p>
