Forensic Facial Specialists Can Identify People Using Just a Couple Facial Features

Forensic facial specialists can accurately identify individuals using only a few key facial features, according to a recent study. Researchers from the National Institute of Standards and Technology recruited 27 experts from the federal government to test their abilities. The specialists were presented with images of two similar faces and one hidden face, tasked with identifying the obscured face by uncovering nine different features, including ears, eyes, eyebrows, forehead, chin, nose, mouth, neck, and cheeks.

Astonishingly, the experts managed to correctly identify the hidden face 90 percent of the time by exposing just one or two features. Ears emerged as the most useful feature for identification, although the specialists strategically selected other features as needed. The study, published in PLOS One, suggests that forensic facial specialists have a remarkable ability to adapt their strategies based on the specific face they are examining.

While the findings have implications for training both human and AI facial recognition systems, the researchers emphasize that the experiment doesn't perfectly replicate real-world conditions.
