From ancient methods such as trial by ordeal to more modern techniques like the polygraph test, the search for a reliable and accurate lie detection method has been ongoing. With the advancement of technology, new methods have emerged, such as fMRI and eye-tracking devices. But are these breakthroughs or just hype? In this article, we will explore the potential of fMRI and eye-tracking devices for lie detection, as well as their limitations and ethical considerations.
