I think history has a huge impact on people's beliefs and behavior today. As the videos mention, bias has come not only from Jim Crow laws, but from entertainment and messages that have been shown to society for decades. Bias exists in our society from the beliefs that these messages have instilled. For example, as one of the videos mentioned, society is taught that "black=threat." If anyone has had a chance to watch the "13th" documentary, you might remember the part where they described that the news tends to portray POC as criminals more often. The idea of African Americans as violent criminals is perpetuated by our media to this day.
