The lion's death wasn't the only shocking poaching incident this week, as five elephants were slaughtered in Kenya.
Imagine going to the U.S. border with Mexico, and instead of talking to a border agent, you talk to a machine.
It asks you questions like “What’s your full name” and “Are you a citizen of the United States.”
All the while, the machine is monitoring different aspects of your behavior: how your eyes are moving, how your voice changes, how you pause between answers, how you fidget.
Taking these markers together, the machine – called an Embodied Avatar kiosk – can determine whether or not you’re being truthful.
This is the cutting edge of research in deception detection, which remains a surprisingly mysterious field, even though we’ve been building lie detectors for almost a hundred years.
