I found this article pretty interesting. It describes differing levels of empathy for people due to race. It talks about people being under medicated for pain, as well as mentioning an experiment where a person of color was given a longer sentence than a white person in identical scenarios.
I hadn't really thought of othering in quite this light, so I figured I'd share.
Here's a link to the article.

Fair warning about the comments, they're icky.
