Joe Biden is correct that violent crime is near a 50-year low

“You risk your lives every day for the safety of the people you don’t even know. That’s why each of you, each and every one of you, is a hero. It’s no accident that violent crime is near a record 50-year low.”

I find the actual quote kind of problematic on multiple levels. ACAB aside, not every cop is a good guy let alone a hero.

And he is crediting police with a record 50-year low? I don’t buy that.

But yes, the perception that Republicans are “tough on crime” needs to go away cause their fear mongering has nothing to do with actual crime prevention.

it's also just wrong.

It's the lead folks. Biden should be crediting the EPA.

Something about causality and correlation…

[–] UnderpantsWeevil@lemmy.world 15 points 5 months ago

Correlation doesn't imply causation, but it does waggle its eyebrows suggestively and gesture furtively while mouthing 'look over there'.

Again, it's not been shown to be a significant factor in the drop in crime in the 20th century. There's more explanation needed than just lead.

The lead-crime hypothesis: A meta-analysis

Does lead pollution increase crime? We perform the first meta-analysis of the effect of lead on crime, pooling 542 estimates from 24 studies. The effect of lead is overstated in the literature due to publication bias. Our main estimates of the mean effect sizes are a partial correlation of 0.16, and an elasticity of 0.09. Our estimates suggest the abatement of lead pollution may be responsible for 7–28% of the fall in homicide in the US. Given the historically higher urban lead levels, reduced lead pollution accounted for 6–20% of the convergence in US urban and rural crime rates. Lead increases crime, but does not explain the majority of the fall in crime observed in some countries in the 20th century. Additional explanations are needed.

Systematic reviews / meta-analysis

The first meta-analysis of the lead-crime hypothesis was published in 2022. "The Lead-Crime Hypothesis: A Meta-Analysis", authored by Anthony Higney, Nick Hanley, and Mirko Moro consolidates findings of 24 studies on the subject. It found that there is substantial evidence linking lead exposure to a heightened risk of criminal behavior, particularly violent crimes. This aligns with earlier research suggesting lead exposure may foster impulsive and aggressive tendencies, potential precursors to violent offenses. The study concluded that, while a correlation between declining lead pollution and declining criminality is supported by research, it is likely not a significant factor in reduced crime rates, and that the link is generally overstated in lead-crime literature.

The study's implications point towards the potential benefits of reducing lead exposure to decrease crime rates. Such reductions could be achieved through initiatives like removing lead from products like gasoline and paint, water pipes and enhancing lead abatement measures in schools and residences.

Thanks for that.

So, you say biden is killing the small arms industry?

[–] JohnnyCanuck@lemmy.ca 7 points 5 months ago (1 children)

I think saying things like that is also meant to be inspiring. Like when you tell all the kids on a hockey team that they're great and they're gonna kick ass out on the ice, but you know who they're about to play and they don't stand a chance. But who knows, maybe telling them they're great will get one or two of them to dream about being a future hockey hero, and they'll get out on the ice and really kick some ass for once - make that extra pass, hit the net for a shot, or hold off on that big, useless, cross-check to the head that would put them in the sin bin for 5 minutes.

If the kids can dream, so can you, right?

[–] danc4498@lemmy.world 2 points 5 months ago (1 children)

I know that he has to say what he said regardless of if it’s true or not. But the problem is that many cops are actual bad guys.

If a third of your hockey team is perfectly capable of playing well but spends the whole game fighting and abusing their spouse, saying 100% of the team is doing great just gives validation to the bad apples.

[–] JohnnyCanuck@lemmy.ca 3 points 5 months ago (1 children)

Maybe you'll inspire those bad apples to be great.

No, bad apples spoil the bunch. that's kinda the whole thing about that idiom

[–] masquenox@lemmy.world 5 points 5 months ago

And he is crediting police with a record 50-year low? I don’t buy that.

Neither should you - if it's safe for you to walk the streets the pig is the last people on the planet you should thank.
