Recently on PBS Newshour there was a segment about Silicon Valley and their attempts to hire more diverse employees. A focus of the segment was employee training seminars about unconscious biases--where employees do exercises in order to make themselves more aware and careful about these biases.
Studies I've read have demonstrated that racial stereotyping is very real and very instantaneous--and exists among people of all races. But is there any scientific support for these classes being effective in reducing this unconscious bias?
