But back to ethics. If there is any validity to the idea that modern values have been shaped by increased exposure to images and video of other people, thus removing the barrier of unfamiliarity that allows us to treat others instrumentally, then we should see the vestiges of that unfamiliarity quotient in various social problem areas. Indeed, we do:

Recognizing Each Other and the Effects of Racial Differences
Carl C. Bell, M.D.
In this issue of the Journal, Pinkham et al. report findings on own-race and other-race effects in their research on facial recognition in schizophrenia. They highlight the troubling finding in previous studies that African Americans with schizophrenia had greater impairment in recognizing and remembering emotions in faces, compared with Caucasian schizophrenia patients. The authors point out that these previous studies showed only Caucasian faces as test stimuli—a major procedural flaw that no one had anticipated. Pinkham et al. designed a better study in which test subjects—both Caucasians and African Americans with schizophrenia as well as comparison subjects of both races—were shown both Caucasian and African American faces as test stimuli. The authors found that the capacity to recognize and remember emotions in faces is no different between Caucasians and African Americans, whether they have schizophrenia or not. But memory for the faces and discrimination of emotions in them are higher when the study subject is of the same race as the person expressing the facial emotion.
Some interesting follow-on questions for investigation: Would exposure to multi-ethnic faces early enough reduce the emotion discrimination deficit? Is there a learning window? Are there differences between subgroups (more integrated communities show lower deficits)? What is the impact on eyewitness subject identification across racial lines?
