Remember correlation does not imply causation.

Apple prices and divorce rates are correlated too!

My favorite one is chocolate consumption vs nobel prize winners by country.
Honest question: what standards of evidence do people have for concluding causation (in physical systems)?
Experiemnts that try to fix or eliminate other variables.

This is usually not possible for economics and other social sciences.

I think the gold standard is experimenting for physical systems. Then you can control for whatever you want. For medicine it would be double blind study (select participants, split them in 2 groups, then you know the groups are the same, give one group the medicine, give the other group placebo).

And then we get to social sciences - like economics - very hard to make an experiment. You can't just play with the interest rate to write a paper...

Yes, it's difficult to run macroeconomic experiments.

The question still stands. What degree of evidence is sufficient to not be off-hand-dismissed with 'Correlation does not imply causation'?

Since inferring causality is hard, we look for counterexamples that disprove it. Hence the reliance on randomization and the null hypothesis.

A counterexample in social sciences might be that the corresponding relationship is found across methodologies and cultures. This turns a question of causal inference into questioning the power of overturning longitudinal data. Statisticians differ about the philosophy on that.

I agree it depends on the domain.

“Successful randomization” might be a more helpful term than “gold standard” here because in this domain the amount of covariance with gold prices is embedded into some people’s arguments.

In social sciences: natural experiments.

In medical sciences: interventions.

Given the stated aim of higher interest rates is to increase unemployment, it's not a stretch to expect a causative effect. That said, I'm sceptical the higher interest rates achieve the stated aim in any sense, though even screwing over the poor with higher mortgage and loan payments could easily increase crime.
Except when the higher interest rates result in a "soft landing".

https://www.noahpinion.blog/p/how-did-the-us-achieve-a-soft-...

And yes, higher interest rates do reduce inflation.

I know people keep saying "higher interest rates do reduce inflation", but I'm yet to see any supporting evidence for this. Japan is a nice example where the exact opposite appears to be true.

The soft landing in the US could easily just be down to the stimulus effect of handing out free money in the form of interest when inflation was going to come down anyway as the supply shocks work through the system.

Interest rates predictably influencing inflation is now on the level of a test of faith.

Good thing the article writer is actually aware of this.
There was a blog which posted funny high correlation quantities. Wonder if newer algorithms can find clusters of quantities and try to infer causation. Like it could determine fuel prices, food prices and people going hungry as a cluster.
Any causation where someone lives to tell the tale, is tricky to fully tease out. Everything is feedback loops.
If you correlate ice cream consumption with accidental drownings amongst children you will find a striking match up. I propose to ban ice cream to limit drownings.

Or maybe it is because it is summer when most kids eat ice cream and go swimming?

Of course it is easy to put these two things together, but it is much harder with economics to know if there is a simple answer or a complicated one.

Well, we can test this counter-factual by banning ice cream during the summer and see if it affects the number of accidental drownings. do(X)
I am not an economist but that claim looks bogus to me. I suspect a lot of indirection between crime - GDP - interest rates, which makes me suspect a spurious correlation.
Also cherry-picking metrics and ignoring others (imprisonement rate), is trying really hard to push an "implication".
The article dealt specifically with imprisonment rate, and cited numbers for how it correlates poorly, and constantly lags, as well as a source which suggests increased imprisonment might actually contribute to more crime.
Did you read the article? The bulk of it is dealing with the indirection and other factors.
to all the quick replies below, the article actually goes a bit in the possible causation and how higher interest rates might relate to higher financial stress in society and how that relates to crime rates.
Do they control for unemployment?
Why would they want to? Part of the hypothesis is that interest rates drive increased unemployment which drives crime. Overall their thesis is that interest rates are a leading indicator of economic stresses that highly impact crime rates.

The report uses data from the Uniform Crime Report. UCR records crimes reported by the police, which isn't the same as crimes occured.

It's likely the link here is between Government Budgets (including budgets for police resources), and Interest Rate. Low IR generally happens in response to recessions. Budget cuts (including police budget cuts) also happen in response to recessions. Police activity reduces with reduced police budgets. Crimes reported to UCR reduces with reduced police activity.

However, inflation versus crime is studied across nations with academic rigor. Bias from a single source does not undermine the conclusion that inflation is a higher factor in certain crimes than, say, unemployment.

https://pinkerton.com/our-insights/blog/inflation-and-crime

"Academic rigor," especially in these social science studies, has usually come to mean "fraud" or at best "bad methodology".

Search "Reproducibility Crisis", "Dan Ariely" or "scientific fraud" and you should get the jist of why you shouldn't trust many headlines for new discoveries right now. Especially "surprising" results that go against expectations

https://www.nature.com/articles/d41586-023-03486-5

https://www.newyorker.com/magazine/2023/10/09/they-studied-d...

This is not my field, but I remember that article as completely undermining your claim that “academic rigor” “usually” implies “fraud”.

My take on the replication problem (I’m not a social scientist) is that we now think the original experiments missed a confounding factor out of ignorance or lack of statistical sophistication.

This is not how Ariely and Gino were caught, though. I wouldn’t call their research surprising at all (again, not my field), but their randomization failed. Replication should have found a different level of support and introduced skepticism of the rigor of their methodology.

>usually come to mean "fraud" or at best "bad methodology".

It's what I originally wrote. Good job cherry picking. You sure this isn't your field?

Ok, so my take on the Nature article that it painted a rosy picture of today’s dispersed research teams mutually verifying each others results. Is your argument that the bad-old days still taint modern methods?
'headlines' are not the 'result's.

You should always take media 'headlines' about science with a grain of salt.

Not just for social sciences, but for dark matter, string theory, everything.

The replication crisis is bit overblown because the 'right' want to use that to drive their own more 'biblical' view of the world. By sowing doubt about all science, like done with cigarettes.

Social sciences do replicate at rate over 50%. That is long way from nothing replicating. Sorry 50% isn't good enough, it isn't like string theory is replicating, and nobody is getting out pitch forks.

another take https://www.vox.com/future-perfect/21504366/science-replicat...

It should be noted the ‘left’ also wants to use this in order to drive their own worldviews. They are both sides of the same coin after all.
False equivalence. The Left has an agenda, sure. The Right believe they are gods chosen and are fighting a holy war.

The Right believe they are being directed by GOD. Their soul will be tortured for all eternity if they don't fight a war on earth following the will of God.

How do you argue a factual point with someone that is basing their decision on being directed by the god of the entire universe.

Basically the modern Christian Right, is fighting their own Jihad. We just don't have a good word like that to describe it.

So, I would disagree they are two sides of the same coin.

The left is maybe skewing some statistics, while the Right is ready to kill people for their god (checkout how many mass shootings are based on Right Talking points).

For clarity, the Rosenfeld study referenced in the Pinkerton article (while talking about inflation rather than Interest Rates) also uses the UCR dataset as its primary datasource, while its european equivalent, also collected from police reporting, is used for its non-American datasource.
Yeah, the section intriguing to me was:

‘ The work of the historian David Hackett Fischer identified four major instances of inflation in Western history, in the 14th, 16th, 18th, and 20th centuries. In each of these periods, violent and property crime rates increased, and then fell once prices stabilized. When inflation decreased in the early 1990s, both Europe and the United States saw a corresponding decline in crime.’

Other sources use something called the Modified Wald Causality test, which should only be convincing to someone already acquainted with the field. The modern European data comes from Interpol, which might suffer the same collection bias as USA. We’re looking at first-order changes, anyway, so I wager this causality test can be sensible, even if the incoming data suffers from a linear bias.

hm... there's some correlation definitely. most likely there's simply the common factor behind them, which is the economy. (bad times get the knives, good times make you nice)

> UCR records crimes reported by the police, which isn't the same as crimes occurred.

What data would be better?

Crime survey data often removes many of the noise in recorded crimes data. Basically surveying a cross section of people and asking them if they've been a victim of crime in the last X months, and what type of crime.
A survey doesn't sound very accurate, since some people are more and less likely to be victims of crime. If drug dealers are killing each other and robbing each other, that is still X number of homicides and robberies during the year that the police investigates, while 0% of surveyed have been victims.
Why do you think that the survey wouldn't include drug dealers in the respondents?
Very few people are drug dealers, so unless you ask everybody, they will not be included.
Wouldn’t this be fixed by doing a proper, representative survey?
Insurance claims for stolen property and health stats around number of stabbings? Not perfect, but perhaps useful to validate UCR data.
I would love to see any rigorously documented causation or even correlation between police budgets and crime rates.
A cursory watch of the "Hamsterdam" season of The Wire, or the "serial killer" one, will be enough to remove any faith in the accuracy of police stats. (Yes, it's fiction, but it's based on years of hardcore journalistic experience "on the crime beat" by show writers).
>UCR records crimes reported by the police, which isn't the same as crimes occured.

No, but it's the best available proxy.

How often do police departments have budget cuts? Union negotiated contracts usually do a good job of protecting at least the rank and file...
Does that imply that US society becomes disfunctional if there's no access to debt? What's making it impossible to function within the existing budgets and causes this huge dependency on borrowing with cheap rates?
Borrowing impacts jobs, and housing costs, both of which have outsized effects on people's budgets.
Ok, but why is the impact of borrowing costs so big on the US?
It's intentional. When the institutions responsible talk about 'raising interest rates', they implicitly add 'to increase unemployment which will reduce spending and reduce inflation'.
Why are we assuming this is US specific? Does it not happen in other countries? (Not rhetorical, i have no idea what the answer is)
Why would it not be? As long as there is credit available, supply of it will drive demand for products and services, and property, and either creates jobs and/or affect prices also for people who never borrow. The reality is that there are very few places in the world where people in general can afford to buy property without borrowing for example, and rental prices tend to reflect purchase prices.

If the entire economy is structured around the expectation of low interest rates, then raising interest rates would certainly upset a lot of plans. Many businesses would find they could not afford to employ as many people as expected. Many employees would find not only that they had lost their jobs, but also wasted many years training for a job that no longer exists.

Those who invested in affected businesses or capital goods with inflated prices due to easy credit will find those investments collapsing in value.

Eventually, the economy could restructure into a more sustainable form, where investments, business sizes and training were aligned with the new state of the economy. But a pain period is not really avoidable, other than by relowering interest rates. The longer interest rates are kept low, the longer and more painful the transition.

> Many businesses would find they could not afford to employ as many people as expected.

How does that work? Are they regularly covering their payroll with loans?

I believe that many business indeed operate at a loss for extended periods of time, by deliberately spending more money on future developments or obtaining customers than they take in revenue.
This was definitely true for tech in the last cycle, but how true is this both outside of that industry and historically at all?
Any big business lives on loans. Which is why you see, for example, retailers going bust right before Christmas - which "surely" should be the busiest and most profitable time of the year...? But to go through it you need to buy inventory, which requires loans - if you can't raise money, because the market thinks you're already in bad shape, you have to close up shop.

Most significantly-sized businesses rely on credit week-in week-out, and tend to implode very quickly if the market turns off the tap.

The first hypothesis that comes to mind is that a fixed percent of people experience a financial stress every year. If debt is available they use it. If not they become desperate and turn to crime.
Does the availability of debt for individuals really vary that much in a high vs low interest rate environment? I feel like high interest debt is available whether the Fed funds rate is 0.75% and when it's 5.50%.
People at the margins have a lot more trouble accessing even high-interest debt than you probably do. Some of them actually have nontrivial default risk that makes even arbitrarily high interest rates plausibly not worth it.
Sure. Does that availability change meaningfully with a change in broader interest rates, though?

Is there a lender that decides to stop making payday loans and buy T-bills instead?

Because parity of expected returns is achieved roughly when interest rates remain roughly proportional along the risk curve, and of course subprime loans are particularly sensitive to repayment risk as rates go up, it's absolutely possible to get priced out of payday loans.

At the level of individual lenders, this looks more like all institutions shifting slightly toward lower-risk lending across the board than any individual lender choosing to buy t-bills instead of making payday loans. But then again, that's exactly what "maintaining higher capitalized operating reserves" means.

Is this some kind of joke?

Ever heard of Keynes and his liquidity preference theory?

Ever heard of Wolfgang Stützel and his book about balance mechanics?

It's pretty obvious. The person with the money gets to decide and they are allowed to decide to not decide at all.

Since one person's credit is another person's debit, the credit side determines indebtedness. Positive money balances determine how much debt there is in the economy and since people have a preference for holding money balances, those money balances keep ballooning and correspondingly, indebtedness must go up.

No, not a joke and I'm not a college educated economist and indeed haven't read the work of Keynes or Wolfgangs or whomever. Which is why I'm asking, no idea what's going on with your condescending tone?
It's the other way around:

High interest rates happen when there is high inflation

High Inflation is present in periods of poor impulse control from consumers who bid up prices

Poor impulse control periods are not something that happen in a single societal fundamental such as purchases of goods and services, but across the board including crime, killings and drugs

People are looking for a cause and a link between government actions, Fed actions and crime (and other phenomenons), but it's really the contagious seasonality of human behavior that changes . Government and Central Banks are totally part of it, not causing it, they are just people subject to the contagious seasonality like the rest of us.

For the elites this particular contagious season of human behavior means cooking the books of their publicly traded company or starting a war, whereas for those who are not so high in the food chain means stealing a car or punch their nextdoor neighbor after a fight.

> Poor impulse control periods

> the seasonality of human behavior

Is it really a thing? Does impulse control come in waves?

Yeah that sounds ridiculous to me. Yes I can understand that high interest rates come from periods of iresponsible borrowing by capitalists who have become complacent due to low interest rates continuing for a long time. However, to act like this complacency, which is caused by a deep understanding of the economy and business-minded spirit, would also affect the lower classes in some way even though they are largely unaware of the details of the economy or lack the ability to exploit it, is a strange stretch. Even more of a stretch is saying that the lower class equivalent of risky borrowing because of a feeling of security is... doing crime because you feel so secure in your employment?? Why would anyone in their right mind be compelled to do crime because your life is just going too well and you have too many opportunities to better yourself legally? The claims of the article make much more sense.
> > your life is just going too well and you have too many opportunities to better yourself legally?

Internalized concerns about time opportunity cost and sense of urgency and the aforementioned poor impulse control and irrational exuberance, a mix of all of them too.

Test it on yourself, when you are in a good mood or in a 'let's go after it' mood you are more likely to be speeding, the higher the mood, the lower the impulse control, it can drive you up to 120-130 mph maybe while your favorite song is playing and there is a stretch of open road ahead. Even 140 if your car is powerful, and you don't notice it. You are breaking a bunch of laws in that moment without realizing.

It comes from within, it has nothing to do with finances, job market, savings or any reasoned thought. Thank God! Being irrational and getting away with it, and then looking back in a moment of rationality is an emotion that makes us human.

I think you would need to prove to me that most of these crimes are poor impulse control in everyday activities rather than large life decisions that most people don't do when they have other oppurtunities - like joining gangs.
> > large life decisions like joining gangs

Have you ever lived in bad neighborhoods? There is no interview process to join a gang, a person starts with something mundane like moving drugs for some very low ranking affiliate from some area of the city to another. Literally just driving, nothing life changing.

You could rebut, why not become an Uber driver, to which I reply: same amount of money that Uber driver makes in a whole day in about 1-2 hours tops.

When you hear news reports saying "X or Y joined Z gang in 2016 and climbed within the criminal organization" , you can be sure that the first mundane task he made for some low ranking affiliate back in 2010 perhaps even earlier.

And do you not think that the problem with the gang giving you way more money is caused by minimum wages being well below the living wage (so legal work keeps you in poverty), social mobility being low (so working hard never gets you an improvement in your lot), unemployment being high, and people's only choices being jobs where they have zero hours contracts and reduced workers rights like Uber (making again, it seem less worth it and still sorta risky as a choice). Deciding to run drugs for a gang is again, not something you do on impulse like pushing harder on the accelerator pedal. You do it based on cost-benefit analysis. This cost benefit analysis comes from you being exploited my capitlists making record profits. They are having a great time and are borrowing recklessly. The people at the bottom of society do not see any sort of benefits proportional to the labour they would have to put in to participate. They are clearly not just happy campers suffering from poor impulse control from having it too good.
> > Does impulse control come in waves?

We know inflation, debt and violence do. What human behavior can possibly be the base cause for such effects?

High Inflation is present in periods of corporate price gouging when given the opportunity...
Despite what your indoctrination books say, consumers don't set prices - businesses do. You don't "bid" on the price of food, stationary, tyres... In fact, in developed economies consumers can "bid up" very few items - basically only real estate. The price of everything else is supply-driven.

High inflation, in the modern world, happens at times of shocks on the supply chain - energy, raw materials, catastrophic events and so on.

I don't know why you'd peddle some pseudo-psychology with a side-serving of bad moralism, but it's not the truth.

> > I don't know why you'd peddle some pseudo-psychology with a side-serving of bad moralism, but it's not the truth.

Businesses don't exist in vacuum, they are always maniacally monitoring how fast or slowly consumers buy up all their inventory of that particular item or grocery.

You should stop acting like everybody isn't watching everybody else in the pursuit of maxiumum result with minimum effort. Even you are doing so right now by looking up at what 'the other side' (businesses) are doing and trying to politically ostracise 'the other side'.

I said consumers in my OP just because they are a largest group of people, because it also includes business owners, they too are consumers! I further believe the largest group of people always has the lion share of input in a phenomenon.

But of course when a business owner arrives on their premises in the morning and stops wearing the hat of the consumer, they will too be subject to impulsivity by making a impulse purchase of some item from their supplier (based on data, or even more probably gut instinct that it would sell), and the supplier does the same with the farmer, or the raw material procurer etc. etc.

Everybody is watching everybody else, they see that impulsivity pays rewards so they start acting impulsively too, this affects and spreads among the population very evenly regardless of social class, the higher classes impulsivity and impulsive purchases just makes the news while the lower classes doesn't.

> they are always maniacally monitoring how fast or slowly consumers buy up

Of course, but consumer behaviour on most items is relatively fixed, and largely reactive to shocks. That is very visible in the current situation: we had little or no inflation for 20 years and then BANG the cost of natural gas and wheat skyrockets because of herr Putin, and suddenly we're in an inflation-heavy world. That's not consumer-driven, that's supply-driven.

> trying to politically ostracise 'the other side'.

I'm not ostracising anyone. The fact is that prices are set by business owners to maximize their profits - that's just how it is. Consumers can only react to that. Your quixotic comments try to blame consumers for "impulsively" paying higher prices for food or basic supplies, and that's just preposterous.

> consumers in my OP just because they are a largest group of people, because it also includes business owners

No, it does not. Gas-industry CEOs don't bid on gas supplies for their own garage or "impulsively" because they like it; they speculate on a scarce resource, rationally taking opportunities to maximize their gain - and that is what drives inflation, the selling side engaged in rational maximization of profits. Same for petrol, wheat, etc. Everything else, including final consumers, can only react in cascade effects, and trying to blame them is just cruel.

You are kind of on the right track but still messing up.

Interest rates are up in times of present scarcity and future abundance.

So given a supply shock that increases scarcity, there might not be enough resources for everyone.

Then you will see both crime and interest rates coincide.

Meanwhile if there are enough resources for everyone, it is obvious that simply working will get you the resources you need.

Enough resources for real time order and consumption, maybe.

But the thought process that compels people (both consumers and businesses) to desire more than real time order and consumption , or even just upgrade to products that are more intensive as far as raw materials are concerned, is psychological and contagious.

It's not like everybody suddenly arrived independently at the same conclusion

The real startling link is between wealth inequality and high crime.
Given that high interest rates mean it's very advantageous to have money, might interest rates just be a leading indicator of wealth inequality?
As it turns out, low/zero interest rates since 2008 have led to asset bubbles just about everywhere - which of course benefits wealth holders. Housing being the most egregious example.

Hopefully the return to normal rates will deflate those asset bubbles.

Thing is, for as insane as they may seem on the surface, assets prices have managed to keep in line with the return on investment. The returns are where the gains have really been made. In other words, it is not so much an asset bubble as it is a consumer activity bubble.

Which is unsurprising as that is specifically why the rates were lowered in the first place – to spur on consumer activity when it started grinding to a halt in 2008. And why rates have risen again recently – to try and tame consumer activity amid a supply chain no longer able to keep up with it.

So, yes, as consumer activity declines, asset values will go with it. But that also means less for the average Joe. As people have to do with less, it isn't too hard to think that crime will increase as a result. When there are no longer toys to placate them, people will find something to do.

This sounds really dubious.

They talk about rates affecting unemployment which affects crime, but if you look at the unemployment chart, it is completely out of sync with the rates vs crime chart that they base their argument on.

To a lay person this just sounds like thieves are denied the easy thieving button during high interest rates, and substitute their income with IRL thievery.
Does this replicate outside of the US? How is it for Singapore, or Sweden, or Saudi?
Low interest rates create a lot of well paying jobs. I think there should be no interest at all for the greater good...

I also think crime would not exist if everyone could afford basic necessities

Was reading somewhere crime is an intended produce, necessary to maintain a government in place to run the system.

Government: look, without us who would protect you from criminals.

It probably needs more than just criminality. But "foreign" threats would probably not be enough to justify how large government entities are throughout the globe.

Governments consciously or unconsciously need crime so would always make sure it doesn't get entirely eliminated.

Me think governments also like unemployment, since they provide unemployment and other social benefits.

I think they also like narcotics, ensuring not only constant supply of crime but also feed into the pharmaceutical business. Once you are hooked it's rather simple to pick you up and hook you to the official, legit drugs. At least for a while.

Wouldn't go as far as saying they may also benefit from epidemics and pandemics, they do provide the convenience to mandate everyone to stay home right before social protests get too well organised, that would be a stretch. Not an impossibility though.

Turkey tried this, results were catastrophic. Google erdoganomics. We had 8% annual interest and an annual inflation of over 100%, fun times.
Assuming he uses the zero interest money to do austerity, it could work, at least in theory. Except Erdogan never intended to do austerity. He just wanted to borrow money at low interest. I admit that I misunderstood his intentions.
The problem was that Erdogan borrowed at a higher interest rate. The issue with countries outside of US is that the local currencies are not accepted anywhere so you cannot cover your deficit by printing money. You need us dollar, gold reserves to back the value of your currency.

If you decrease interest rates while you have high inflation, people spend like there is no tomorrow. If you could buy 2 loaves of bread and 2 tvs today, you can only buy 1 loaf of bread and 1 tv in a month's time. So you buy and stock. This creates increased demand which creates increased prices.

At some point you don't even know what the prices of things are, manufacturers don't know it as well, so they increase the prices higher to cover anticipated future costs. Your wages rise but your purchase power declines each month.

Portions get smaller, prices get higher, you live a shitter life.

Inflation is the mother of all evil. If high interest rates are needed to keep it under control it is worth every effort.

One assumption I don't see covered at all, they seem to be assuming that the percentages of total crime being reported to police is constant.

The study uses UCR data which only records the number of crimes reported to police. How can we know that the correlation here isn't actually that the likelihood of a crime being reported is linked to inflation? I.e. with lower inflation I'm less willing to deal with reporting some types of crimes to police, but with higher inflation I'm stressed personally and financially and am more likely to report a crime.

This is junk analysis because there will always be signals that randomly correlate. There are a lot of signals out there that we can plot pairwise and the axises here aren't identical. All this says is that long term interest rates formed a hump shape, and crime formed a hump shape. There are so many hump shapes it is just a matter of finding 2 humps that peaked around the same time.

Not only that, but in this case peak interest rates were around the infamous 1970s era when a lot of policies change. So even if these are related, there is probably a hidden variable that a lot of policies changed at the same time and the two series still aren't causally related. There was likely a policy refresh on how crime gets handled at the same time as there was a policy reset on how interest rates were managed.

Yeah, this is exactly what I thought. Interest Rates correlate to a lot of things. Seems like stretch to say there is a cause, not just correlation.

Like, there is more crime in cities, but, because there are also more people. What is per-capita crime. Small town with 10 people, 1 felon, man, they are 10% felons.

> Seems like stretch to say there is a cause, not just correlation.

A better take might be that they reliably happen together.

The statistical analysis doesn't seem to go beyond correlations, so this could well be just an instance of https://en.wikipedia.org/wiki/Spurious_relationship, ie a statistical fluke like marriage rates correlating negatively with longevity or pirate activity with climate change.
It may be but that doesn't mean it's not interesting. I doubt the relationship for is truly spurious but it's certainly indirect. Even if we determine that crime and interest rates are driven by the same external forces it will force us to evaluate policy on another axis.
The link between the decline of piracy and rising global temperatures was the industrialization of the British empire - studying piracy (unsurprisingly) wouldn't have yielded any insights on climate change. Similarly, interest rates may have not much to tell us about crime.
When observed over short timeframes, there is clear seasonal variability along with decline in oceanographic piracy when the weather conditions are unfavourable to the activity. A study on the decline of piracy over the long timeframe would notice that the trend is down due to increasingly rougher seas – caused by climate change.
economic stability correlates with low crime rate, color me shocked
"almost perfect correlation" is an interesting way to describe 0.77
A much more interesting link is between crime and atmospheric lead emissions, which looks similar to this but conforms much more tightly. I'm more inclined to buy that than interest rates considering we have more direct evidence between lead exposure and violent tendencies.

High interests rates are linked to poverty and it would not surprise me if more violent crimes were commited in poor neighborhoods
What if we eliminated interest rates (as technically, they constitute the exploitative practice of usury, and therefore theft), and opt for equity participation instead?

(This is how Islamic banking operates, as riba is forbidden. Indeed, usury is also condemned by the Church, and Catholic banks would sustain themselves on, e.g., service fees for the labor involved in, say, issuing a loan or investing on someone's behalf or whatever. And the Jewish Talmud forbids taking interest between Jews, though it does permit charging goyim interest. Regardless, you do not need to appeal to religious law or teaching as these merely reflect the demands of justice and just economic exchange.)

"if you give everyone lots of free stuff, they won't be killing each other as much as usual because they will be too busy chewing". Who could guess.
