Spafford On the Use of Lie Detectors by the US Gov’t
Interesting article in zee work blog:
Noted security and cybercrime expert Eugene Spafford discusses the challenges and complexities in the use of lie detectors by the US Government to screen for security clearances. “Lie detectors have a non-zero rate of error. As with many real-world systems, these errors manifest as Type I errors (alpha error, false positive) and Type II errors (beta error, false negative), and instances of ‘can’t tell.’ It’s important to understand the distinction because the errors and ambiguities in any system may not be equally likely, and the consequences may be very different.”
