Reading faces an imperfect science
October 6, 2011
The Vancouver Sun:
Millions of dollars may be being misspent on threat-detection methods that rely on facial expression recognition, according to a report this month by a noted Canadian researcher.
In the October issue of the journal Current Directions in Psychological Science, Lisa Feldman Barrett rebuts the notion of there being six to 10 biologically basic emotions that are encoded – and easily interpreted – on people’s faces.
Barrett, a professor at Northeastern University in Boston, instead presents evidence that context “dramatically” shapes people’s ability to read emotion in a face, and that deciphering facial expressions on their own is at once misguided and a risk to public safety.
