... stereotype is so pervasive in the US culture that it is even internalized by the ingroup.

What leads them to conclude that this is a stereotype?

They spent time and money on this? Niggers commit orders of magnitude more violent crime and are fucking dangerous. Of course White people are going to be on guard around them.

If you normalized the data with respect to conviction rates for violent crime, I would imagine that the "bias" would probably vanish. People aren't apprehensive of black males, they are apprehensive of people who they view as more likely to commit violent crimes against them. That is also why people are not apprehensive about asian males, as they have a very low rate of violent crime.

People, and even niggers, don't like niggers because niggers are violent.

Just because something is a stereotype doesn’t make it false. The data on this one is very clear.

Niggers are far more violent than people.

I decided to look up the etymology of the word "stereotype" and guess what, the individual who coined the term to mean what it means today is of course A JEW!!

Etymology: https://www.etymonline.com/word/stereotype

Key takeaway:

The specific meaning "preconceived and oversimplified notion of characteristics typical of a person or group" is recorded by 1922 (Walter Lippmann, "Public Opinion").

Early life excerpt from his jewkipedia article (emphasis mine):

Lippmann was born on New York's Upper East Side as the only child of Jewish parents of German origin.

Once again, my jewdar is successful. It's honestly tiresome how it really is EVERY SINGLE TIME.

What a waste of money to fund a study that concludes what EVERYONE knows.

Niggers tense up around niggers. Thus, niggers are racist.
