onthebeach there was another interesting topic buried in the article I linked to in the post that followed that one https://archive.is/ccDaI#selection-1963.101-1963.244

"The WSU article did not find that the officers studied were free of subconscious racial bias — far from it. In fact, fully 96 percent were more likely to associate images of weapons with black faces on the Harvard University Implicit Association Test."

I can't see any references for that claim but one of the more significant reports on implicit bias using the Harvard test was McConnell & Leibold (2001)

I've not dug through it enough yet but there are some strong arguments that the test is not doing what it's proponents think it is, doing more to test for in group/out group preference rather racial bias. I've also heard claims that the finding regarding a high level of implicit bias against blacks were actually reversed.

A few links covering problems with the implicit bias test which appears to be behind a lot of the claims about police bias against blacks in the US.

Thank you.

Otb,

"A hysterical member of the public, someone very much like yourself maybe, reported a gun offence."

Pfft....here are a few examples from the US.

"'It's not illegal to be black': Cops complain online about white people getting 'freaked out' by their black neighbors and wasting police time with 911 calls.

One officer was called to investigate two black people jump-starting a car.

Another cop was dispatched to confront a black man fishing in a pond.

Woman dialed 911 after seeing 'mean-looking Middle Easterner' on street.

"‘So I'm working last week and get dispatched to a call of 'Suspicious Activity.' Ya'll wanna know what the suspicious activity was? Someone walking around in the dark with a flashlight and crow bar? Nope. Someone walking into a bank with a full face mask on? Nope.

‘It was two black males who were jump starting a car at 930 in the morning. That was it. Nothing else. Someone called it in. People. People. People. If you're going to be a racist, stereotypical jerk... keep it to yourself.’"

"A former 911 dispatcher called Nursehokiehi said that lots of people rang in to report a ‘suspicious person’ and when asked for clarification as to what was suspicious about the individual, ‘most would mumble, stumble or even whisper “umm, he’s/she’s black” or “Muslim-looking”’.

Nursehokiehi added: '[replying] "Ma'am, it's not illegal to be black (or Muslim, or Mexican, etc)... " usually worked.'"

"Other racist complaints aired on the thread include a lady who called the police because a black man was sitting in a truck opposite her house, a woman in a college town who reported a ‘middle easterner’ strolling along looking ‘mean’"

"....‘We frequently get calls about black men and women and kids, yes kids, walking. Like WWB [Walking While Black] was actually a crime and not a Twitter joke.'"
