A Brief History of the Lie Detector

It’s surprisingly hard to create a real-life Lasso of Truth

When Wonder Woman deftly ensnares someone in her golden lariat, she can compel that person to speak the absolute truth. It’s a handy tool for battling evil supervillains. Had the Lasso of Truth been an actual piece of technology, police detectives no doubt would be lining up to borrow it.

Indeed, for much of the past century, psychologists, crime experts, and others have searched in vain for an infallible lie detector. Some thought they’d discovered it in the polygraph machine. A medical device for recording a patient’s vital signs—pulse, blood pressure, temperature, breathing rate—the polygraph was designed to help diagnose cardiac anomalies and to monitor patients during surgery.

Mice, windows, icons, and menus: these are the ingredients of computer interfaces designed to be easy to grasp, simplicity itself to use, and straightforward to describe. The mouse is a pointer. Windows divide up the screen. Icons symbolize application programs and data. Menus list choices of action.

But the development of today’s graphical user interface was anything but simple. It took some 30 years of effort by engineers and computer scientists in universities, government laboratories, and corporate research groups, piggybacking on each other’s work, trying new ideas, repeating each other’s mistakes.
