One way to check this is to look at my graph of the 60 biggest cities ranked in order of increase in murder victims from pre August 9, 2014 to the same time period in 2015 (based on Carl Bialik’s data in FiveThirtyEight.) The biggest absolute increases have been in heavily black cities.
The Obama Administration’s promotion of BlackLivesMatter rageaholics seems to be encouraging blacks to murder blacks.
Okay, heavily black Baltimore tops the chart, but Memphis--which has a population that is almost identically black (63.1% to 63.3%, respectively)--is second to the bottom. Chicago is near the top, but Raleigh, a city in the South, has seen an absolute decrease in homicides. It's basically a wash. Racists will see what they want to see!
Fortunately, regression analysis can help resolve this dispute. Using Census quick facts data, we find that the correlation between the percentage of a city's population that was black in the 2010 census and the absolute change in the number of homicides it experienced in the first seven months of 2015 compared to the first seven months of 2014 is .44 (p-value = .0006).
When a single variable correlates this robustly with an outcome in the social sciences, it's worth paying attention to, even more so when we take into consideration potential discrepancies in the geography of police jurisdiction in 2015 and the geography of Census city designations in 2010. Noise and imprecision in measurement will virtually always weaken perceived correlative relationships. In other words, the true relationship is probably even higher than .44.
Steve is one of the best in the business at noticing patterns, so it comes as little surprise that his general impression has empirical validation.
A plausible and seemingly obvious consequence of the "black = good, white = bad" narrative, embodied most saliently in the Black Lives Matter movement, is that blacks feel let off the leash. A corollary to that, though, is that whites tend to feel even more restrained (at least until they come to a breaking point and abruptly and savagely tear the arm off of the hand that has been slapping their cheeks for a generation).
When blacks, who already behave relatively poorly, are encouraged to behave with still less restraint than before and relatively well-behaved whites are simultaneously shamed for even allowing a putatively improper thought to materialize in the recesses of their minds, the gap in civilized behaviors between blacks and whites grows yet wider. Falsely portraying predatory blacks as victims pushes blacks to be more predatory. Falsely portraying white victims as predators pushes whites to become more sheepish (again, for some period of time before the threshold of tolerance is breached).
For awhile, it's great for race-hustling grievance mongers and virtue-signalling ethnomasochistic whites alike. Good things have a tendency of coming to an end, though.
