Some Evidence That Violent Video Games Reduce Actual Violence

A few weeks ago, we released a podcast called “Who Runs the Internet,” which included Levitt’s thoughts on whether online mayhem, including violent video games, may actually reduce real-world violence.  Here’s what Levitt had to say on the matter:

Maybe the biggest effect of all of having these violent video games is that they’re super fun for people to play, especially adolescent boys, maybe even adolescent boys who are prone to real violence. And so if you can make video games fun enough, then kids will stop doing everything else. They’ll stop watching TV, they’ll stop doing homework, and they’ll stop going out and creating mayhem on the street. 

The Times of Israel recently reported on a new study confirming Levitt’s theory:

The research, done by The Center for Educational Technology, asserts that video games — even violent ones — are beneficial for children on a scale much bigger than originally thought. The claims are in contradiction to other studies that found that extended gaming led to depression, anxiety and stunted social development, not to mention the physical effects brought on by long hours of sitting. Some studies have also linked between video games and increased violent behavior in children, arguing that simulated violence leads to real-life violence.



How Can We Save Ourselves From Ourselves?

John List and Uri Gneezy have appeared on our blog many times. This guest post is part a series adapted from their new book The Why Axis: Hidden Motives and the Undiscovered Economics of Everyday Life. List also appeared in our recent podcast “How to Raise Money Without Killing a Kitten.”

It’s a late-September afternoon in 2009 and the students of Fenger High School on Chicago’s South Side are crossing a vacant concrete lot. Some live in the Altgeld Greens housing project. Others live in a part of Chicago’s rough Roseland neighborhood (also called “The Ville”).  Some of the students from these areas have developed fierce antipathies toward each other, though the groups are more like cliques than gangs.

As the teenagers cross the lot, a fight breaks out. Someone pulls out a cell phone and starts recording a video of 15 to 20 kids fighting. Around a minute into the video, someone discovers a couple of two-by-fours lying in the empty lot. Eugene Riley, sporting a red motorcycle jacket, takes one of the big pieces of wood from a pal and swings it like a baseball bat into the back of 16-year-old honor student Derrion Albert’s head.



The Data on Bar Fights

What happens when a fight breaks out at a bar? A Penn State sociologist gathered data from nightlife venues in Toronto to find out. From BPS Research Digest

Michael Parks and his colleagues trained dozens of observers who analyzed 860 aggressive incidents across 503 nights in 87 large clubs and bars in Toronto, Canada. Aggression was defined as anything from a verbal insult or unwanted physical contact to a punch or kick. Incidents were twice as likely to involve one-sided aggression as opposed to mutual aggression. The most common incident involved a man making persistent unwanted overtures or physical contact towards a female. Male on male aggression was the next most frequent category. All-female aggression was rare.

Third parties intervened in almost one third of these situations, and they were more than twice as likely to intervene in a non-aggressive way than to be aggressive themselves. Eighty per cent of third parties who got involved were men. Drunk third parties were more likely to be aggressive. Surprisingly perhaps, the most frequent kind of aggressive incident (male on female) was the least likely to provoke third party involvement. One-sided aggression between men also provoked few interventions. Parks and his team think this is probably because such incidents are judged to be non-serious and unlikely to escalate.



What Is the Relationship Between Income Inequality and Revolution?

A pair of interesting-looking papers, particularly interesting when paired, about income inequality and its relationship (or not?) to revolutions. From “Russian Inequality on the Eve of Revolution,” by Steven Nafziger and Peter H. Lindert:

Just how unequal were the incomes of different classes of Russians on
the eve of Revolution, relative to other countries, to Russia’s earlier history, and to Russia’s income distribution today? Careful weighing of an eclectic data set provides provisional answers.    We provide detailed income estimates for economic and social classes in each of the 50 provinces of European Russia.  In 1904, on the eve of military defeat and the 1905 Revolution, Russian income inequality was middling by the standards of that era, and less severe than inequality has become today in such countries as China, the United States, and Russia itself.  We also note how the interplay of some distinctive fiscal and relative-price features of Imperial Russia might have shaped the now-revealed level of inequality.



The Violent Legacy of Africa's Arbitrary Borders

Even if they haven’t heard the term Scramble for Africa, most people know that something went wrong when the continent was divided into nation states by European colonial powers.

Some economists, however, have taken the time to quantify the destructive nature of Africa’s national borders. Authors Stelios Michalopoulos and Elias Papaioannou have released a new working paper showing how arbitrary border decisions have affected war and civil unrest in Africa, particularly among split ethnic groups and their neighbors. Not surprisingly, the length of a conflict and its casualty rate is 25 percent higher in areas where an ethnicity is divided by a national border as opposed to areas where ethnicities have a united homeland. Examples of divided (and conflicted) groups are the Maasai of Kenya and Tanzania, and the Anyi of Ghana and the Ivory Coast. The conflict rate is also higher for people living in areas close to ethnic-partitioned hot-spots.



Should Mexican Drug Cartels Be Labeled as Insurgents?

A few weeks ago, Freakonomics received an email from a man in Mexico City describing the effects of Mexican drug cartel violence on daily life and asking for our solutions to his country’s seemingly endless crime problems. This week, The New York Times ran a piece on Mexican drug cartels and growing American infiltration of criminal organizations. Now, a new report from RAND on drug-trafficking violence in Mexico analyzes the situation in the context of an insurgency, bringing to bear research on defense-sector reform.

What’s clear is that the drug-fueled violence in Mexico has diversified over the last decade into several other underworld activities: human trafficking, weapon trafficking, and assassinations, just to name a few. In other words, the cartels are no longer just cartels — they are something larger.

The RAND paper reiterates many points that have become familiar to us about the situation in Mexico: corruption is rife, policing is weak. It also looks at how high unemployment and a “youth bulge” have helped fuel Violent Drug Trafficking Organizations (VDTO). For many young unemployed people, joining a crime syndicate is often the best job option. But the most jarring part of the paper is the discussion and comparison of Mexican drug violence to other insurgency trends around the world. Rather than a war on crime, what if the battle with cartels is really a battle with different insurgent groups?



What Should Be Done About Violent Crime in Mexico?

A reader named Rodolfo Ostolaza writes in with a most heartfelt plea about violence in Mexico. He would welcome all suggestions.

I live in Mexico City and, although the wave of violence in my country has not yet fully reached this area, I’m worried because we are living a state of terror, with bloody attacks, and a lack of humanity. That is why I am requesting your help.
What do you think we can do to change this? According to the chapter on crime reduction in Freakonomics, a judge’s decision was more influential than a change in public policy and law enforcement bodies in reducing crime in the U.S. I wish we could apply this “recipe” (allowing abortion throughout Mexico, which is currently legal only in Mexico City) to keep the hope that, in the future, things will be brighter. However, considering the Mexican idiosyncrasy, with strong influence of the Catholic Church, I believe that this measure would have, at best, a marginal impact.
I want you to share this question with your readers. Give us suggestions, ideas, different perspectives to analyze the problem. What follows are some thoughts and questions of how, I think, the problem should be analyzed.
First we must understand precisely the problem itself. It is true that the violence began to grow exponentially after President Calderón declared war.



Author Steven Pinker Answers Your Questions

Last week we solicited your questions for author and Harvard psychology professor Steven Pinker on his new book, The Better Angels of Our Nature: Why Violence Has Declined. You responded quickly with more than 50 questions. Now, Pinker is back with his answers to 10 of them. The result is a fascinating discussion (exactly the kind we like to have around here) on the roots of violence, the rationale for wars of the past and what a decrease in violence says about modern society. As always, thanks to everyone for participating.

Q Any thoughts on the negative side effects of decreased violence? Overpopulation? More sedentary populations? Decreased role for survival of the fittest? Not to say that violence is preferable, just wondering about the downsides of peace. – BL1Y



Bring Your Questions for Author Steven Pinker

With Libya finishing off a bloody revolution, the war in Afghanistan nearly a decade old, and Mexico engulfed in a savage drug war — it might not seem like it, but we’re living in the most peaceable time in history. That’s more of a commentary on just how violent our past is, rather than the tranquility of the present.
In his new book, The Better Angels of Our Nature: Why Violence Has Declined, Harvard psychology professor Steven Pinker lays out the difference in stark contrast, quantifying the dramatic decrease in violence over the ages, and uncovering the reasons for its decline. Pinker operates under the premise that the past is like a foreign country, and that we need to be reminded of its brutality. Starting with a tour of human history that stretches back to 8000 BCE, Pinker offers glimpses along the way, and shows how in the early going, violence persisted even as society and culture evolved.



Killing What You Eat: The Dark Side of Compassionate Carnivorism

There’s a relatively new category of conscientious consumer on the rise known as the “compassionate carnivore.” These are meat eaters who have chosen, with good reason, to remove themselves from the horrific practices of factory farming. In her thoughtful book, The Compassionate Carnivore, Catherine Friend puts it this way:

I believe it’s possible to show compassion for animals and still eat them. For me, this means paying attention. It means learning more about the animals I eat and taking some responsibility for their quality of life.

A significant number of meat consumers have taken this message seriously enough to become meat producers. Indeed, the urban homestead movement in particular has inspired untold numbers of urbanites to take compassion to the extreme and become part-time animal farmers themselves.
The rationale for this transition is multifaceted, and often quite convincing. “Those of us that raise our own animals,” one of my critics concisely points out, “are doing so because we don’t want to be part of the industrialized agricultural machine that routinely abuses animals for the sake of the almighty dollar.” An urban homesteader from Oakland went one further: “the level of appreciation for nature and life when you slaughter your own meat creates a kind of ethic that I think is what we need to save the world.”



Concealed Weapons on College Campuses

The Texas legislature seems likely to pass a law allowing people to carry concealed weapons on campus. Having observed enough shootings of professors by students in the U.S. over the past 45 years, I think this is a dreadful idea.



The Decline and Fall of Violence (Ep. 43)

Our latest Freakonomics Radio segment on Marketplace concerns a topic we’ve been writing about for a long time: violent crime — and especially why it rises and falls. In this segment, Levitt and I discuss the fact that overall crime and violence are likely at a historic low these days, and not by a little bit either. The conversation builds off the fascinating new book by Steven Pinker called The Better Angels of Our Nature: Why Violence Has Declined.
Pinker has just completed a very good Q&A on our blog, and you’ll hear him in the Marketplace segment as well. Even though many people are convinced that the world today is more violent than ever (can you say “media effect”?), Pinker lays out the facts of the decline and fall of violence in a way that is hard to dispute:



Fighting Suicide Bombers: What Works?

Efraim Benmelech, Claude Berrebi and Esteban F. Klor have already argued that a bad economy equals deadlier terrorists. Now, the three economists have turned their attention to the effects of house demolitions on terrorism.



The Bigger the Group, the Less Likely Pareto Improvements?

All classes were canceled at the University of Texas one recent Tuesday because of a shooting at the main library. I already had a haircut appointment scheduled for 4 p.m. and suddenly had a lot of free time before then. I called the hairdresser and asked to come by at 2. She was free then. This gave me a preferable work schedule; and, as I had been her last appointment, she got off work early.



Italy's Culinary Paradox

Food is fiction, after all, and there are many advantages to keep telling beautiful stories that brighten our day by enriching our palette. Plus, the moment we might start thinking about the culinary implications of a riot, things can become pretty tasteless.



When Radio Kills

During the 1994 Rwandan genocide, Radio Télévision Libre des Mille Collines (RTLM) broadcast anti-Tutsi propaganda and called for violence against Tutsis, which many experts believe significantly contributed to the violence. An interesting new job-market paper by David Yanagizawa seeks to determine the precise role that RTLM played in the genocide.



Do Jobs Really Cure Violence?

Does giving a man a job stop him from becoming a political insurgent? The generally accepted wisdom is that it does. In fact, the U.S. and other western powers have distributed millions of dollars of foreign aid in the hopes of reducing political violence and instability.



When Football Violence Turns Real

It’s well-established that domestic violence is bad for the children directly exposed to it (and possibly their classmates as well) but experts still debate the drivers of family violence. Economists have traditionally characterized violence as a signal to outside parties or as part of an incentive contract between family members.



Looking to Blog Readers for Good Ideas to Reduce Teen Shootings

In the wake of the national publicity that accompanied the beating death of Chicago Public Schools student Derrion Albert, the issue of teen violence has come to the fore.
Violence toward students in the Chicago Public Schools is, however, neither new nor rare.



War Is Over?

The 21st century could represent the end of war as we know it, writes political scientist John Mueller in a new paper for Political Science Quarterly. He notes that there have been no wars between developed nations since 1945, and that other international wars that fit the classic definition — the violent resolution of a dispute between two or more . . .




Do Hamburgers Cause Crime?

Most of us who eat meat regularly would still rather not kill an animal with our own hands. So we have, for generations, delegated that work to others. Jennifer Dillard, at Georgetown Law, authored a new paper looking at what that delegation costs the workers of industrial slaughterhouses. She argues that prolonged work on a kill floor exposes workers to . . .



Interesting Article on Los Angeles Gangs

Peter Landesman has written a fascinating article for L.A. Weekly on street gangs. The events he details are chilling. I can’t say I agree with some of the broader claims of the piece, however. Landesman argues that the gang problem is worse than it has ever been, and that gang violence hasn’t dropped the way other crimes have. A quick . . .



Betting on the End of the World

There’s a new John Tierney column out today, a good one, on doomsday predictions (mostly concerning biological weapons), and who’s backing up their predictions with cash (including Tierney) on LongBets.org. There’s more information on Tierney’s blog, including a link to this interesting essay by Steven Pinker about the overall decline of violence in modern times.
