Artificial Intelligence Spots Hidden Signs of Depression in Students’ Facial Expressions (www.waseda.jp)

Depression is often linked to changes in facial expressions. However, the link between mild depression, known as subthreshold depression, and changes in facial expressions remains unclear. Now, researchers have investigated whether subthreshold depression shows changes in facial expressions in Japanese young adults using artificial intelligence. The findings reveal distinct muscle movement patterns related to depressive symptoms which may help detect depression early, paving the way for timely and preventative mental health care.

As suspected, this paper is based upon Paul Ekman's Facial Action Coding System, better known as micro-expressions.

This controversial literature borderlines on pseudo-science, with Ekman's work having significant conflicts of interest in the form of undisclosed funding from US defence, police, and border control, who wanted Ekman to create systems that can detect lies based on supposed micro expressions. Subsequent independent meta analyses have found that micro expressions cannot be consistently read, even by Ekman's own researchers.

Unfortunately, despite this, world governments have poured millions of dollars into private contractors to develop AI systems based on this flawed research for border control.

Munecat's video essay on debunking body language experts goes into much greater detail:
