I can’t let this go. It’s nothing like that. Yes, you are just positing opinions as if they’re facts, but that’s not everyone. There has been reviews of the literature. E.g I can’t recall the book off the top of my head but something like out 120 studies on effectiveness of different policing strategies, only ~20% of studies showed statistical significant effects for any given strategy and a fair amount of those failed to replicate. Meanwhile we’ve continually had studies pointing to lead as a significant driver with significant effect sizes. You keep strawmanning this “solely” argument that no one is making while also ignoring the plethora of data pointing to it being a huge driver, and by the far the largest driver with any body of evidence. It’s not like this stuff isn’t being studied, yet I challenge you to find studies that can show anything near the evidence for these other factors.
