The above is the link you referring to. Its inherently bias once again, its a video simulation (not much better than survey) with 100 participants (very small sample size)...plus we dont know how the participants are chose. Either way, a good number of them could just be pulling trigger less on black suspect because they dont want to appear bias. But what i thought was really interesting and the key point in article is that when faced with black suspect their level of anxiety was higher than when suspect was white...so boom right there, stop and ask yourself why??? And bro had it been a real life scenario that increase anxiety translates to pulling trigger faster (i.e tamir rice RIP)...because it was a fake simulation with no real threat, they simply panic and thought about their action a little longer because of the social implications and interpretation that they they maybe bias and hence the hesitation in shooting black suspect....again in a real life scenario with real threat, you could careless how society is going to view you, your increase anxiety will make you pull that trigger faster because you saying to yourself i gotta get home safely to my loved ones.
But the real question is why would the anxiety level be higher upon viewing a black suspect vs any other group? its a rhetorical question.
Lastly the person who conducted the research said in the article "There's an unarguable problem that minorities are overrepresented in officer-involved shootings," James said
