Reading Faces and Minds

The image is unsettling, but more disturbing is the first paragraph, which tells us about “one ancillary benefit” of research carried out by Charles A. Nelson III at Harvard. Nelson evidently outfoxed a Boston car salesman by reading his facial expressions and discovering that he was bluffing. (When was the last time you figured out that a car salesman was “bluffing”? Did you have to watch his eye movements and facial features to figure it out?)
I suppose that research of this kind might be able to tell us about the workings of the child’s mind, but I wonder exactly to what end these children are being fitted with plastic-sponge sensors. And what about the question of consent? “Parents receive a nominal $10 fee, and each child receives a toy.”
