I'm pasting part of a comment I made a few days ago on a different post:
This is called implicit racism, and it permeates our society to a systemic level. Healthcare can be a good example, and the U.S. criminal justice system is the best example imo.
One thing that really drives home the systemic implicit racism in this country are studies that have people rate black and white men on how strong/large/muscular and threatening they perceive them to be. The black men were perceived to be more threatening and that use of force was more likely to be viewed as justified. Black and white Americans both perceived the black men to be stronger, taller, and more muscular than their equal-sized white counterparts. Source
Another study found that people view black boys as older than they are, and that they are more responsible for their actions than white boys, whose actions were more likely to be excused by the belief of childhood innocence. So our society essentially strips black boys of their perceived childhood innocence. Same Source
Also should definitely be pointed out that Black Americans are incarcerated at a nearly 5 times greater rate than are White Americans. Source
Man.. I'm having deja vu...
