1) What information did you get from this source that will be useful for your infographic assignment? 
Similar information from the other articles. However, it does include more specific examples of people being racist and fearing the "different." It also calls out social bias, which I didn't really see other articles call out (I guess prejudice, but this REALLY dives deep).

2) How credible is this research source? How do you know?
They used multiple quotes within their articles. Specifically from certified individuals. But, there are so many sources that they used. It would take forever to list them. Here are some, though:
Psychologist Markus Kemmelmeier, at the University of Nevada at Reno
Henri Tajfel, of the University of Bristol in England
John Turner, of the Australian National University
And more.
