Study Calls Media Violence Public Health Threat

Study Calls Media Violence Public Health Threat

November 28, 2007
A new study which appears to have the support of the U.S. Center for Disease Control and Prevention (CDC) concludes that media violence - including video game violence - is an emerging public health threat second only to smoking tobacco.

Published in the Journal of Adolescent Health, the study by L. Rowell Huesmann (left) of the University of Michigan holds that consuming media violence adds a significant risk that the viewer will act aggressively in both the short and long term.

In conducting his research, Huesmann reviewed over 50 years of data on exposure to various forms of media violence, including TV, film, video game and the Internet. Huesmann, a senior research scientist at Michigan's Institute for Social Research, told Science Daily:
The research clearly shows that exposure to virtual violence increases the risk that both children and adults will behave aggressively... More than 60 percent of television programs contain some violence and about 40 percent of those contain heavy violence.

Children are also spending an increasingly large amount of time playing video games, most of which contain violence. Video game units are now present in 83 percent of homes with children.

Based on their joint research, Huesmann and colleague Brad Bushman believe that media violence significantly elevates the chance that children and adults will exhibit aggressive behavior. How significant is the risk? According to Huesmann:
Exposure to violent electronic media has a larger effect than all but one other well-known threat to public health. The only effect slightly larger than the effect of media violence on aggression is that of cigarette smoking on lung cancer.

Our lives are saturated by the mass media, and for better or worse, violent media are having a particularly detrimental effect on the well-being of children.

As with many other public health threats, not every child who is exposed to this threat will acquire the affliction of violent behavior. But that does not diminish the need to address the threat --- as a society and as parents by trying to control children's exposure to violent media to the extent that we can.

@ distaria

Yeah you have to use actual HTML tags here.
THE SKY IS FALLING, THE SKY IS FALLING!!
Wait... wait... so.... because almost everyone has played games, they're the cause? Let's drudge up a few related arguments. You're wearing red, you must be a commie. You're hair covers your eyes, you must be emo, and must be suicidal. You read books, you are too informed, and a liability, and must be killed. You have foreign friends, you're a terrorist, and must be detained. Sorry... but if all of these seem ridiculous, how does it sound when you try to single out a demographic that comprises of 98% of people under the age of 50 or something.
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAHHHHHHHH!!!!!

This is the most insane 'research' that I have seen in my life....

If I said that: I just did a study that air cases cancer after all everyone who has cancer breaths right???
THEN I WOULD HAVE A MUCH MORE REASONABLE ARGUMENT THEN THE ONE PRESENTED BY THE STUDY.....

Crime rates plummit as violence in media rises therefore media violence causes violence?????
Who ever said that aggression is bad????
Games worse than drugs, disause, poverty, guns etc????

WTF?!?!?!?!?!

These hacks are the worst spindoctors that I have ever seen....
For some reason the quote "When you gotta go, go with a smile!" From Nicholson's Joker came to mind.
...What?!?

Lemme get this straight- playing a video game or watching a violent movie is more dangerous than a car, living in poverty, disease, and doing drugs?

Can I have some of what they're smoking?
They took a sip of JT's bong water, didn't they?
The FACT is that this "study" was done by "reviewing" old, improperly, incomplete studies that did NOT take individual factors into consideration. Therefore, it's just more of the same baffoonery by incompetent researchers who couldn't tell you squat about the complexity of individuals and just want to spread more lies and deceit in the form of stereotypes.

Over the last 50 years, society as a WHOLE has changed. Events have taken place on grand scales. And each individual reacts differently to those situations for a variety of reasons. It's nice of them to play the "placate card" with the bit about "As with many other public health threats, not every child who is exposed to this threat will acquire the affliction of violent behavior." But of course, then they spew out the further nonsense of trying to bolster the stereotype watch, play, or read violence and you'll be violent.

This "study" is nothing more than sensationalistic tripe to aid in the continuation of fear mongering and misinformation to cover up incompetency on the part of many researchers. It's a good thing there are a few good researchers out there doing some good work. I wish THEY would get more attention. But apparently, the journals and even the government LOVES sensationalism rather than TRUTH.

However, despite living in an era "saturated with mass media (tm)," we have one of the lowest crime rates in our history? Or take Japan! Those folks are obsessed with games and TV and the like, yet they have one of the lowest crime rates in the world. The only possible conclusions to me is that these folks were either studying a parallel universe or are making sure to find exactly what they want to see.
"not every child who is exposed to this threat will acquire the affliction of violent behavior."

I think he should tell the truth and say "An incredibly small percentage of children, maybe 1 in several million will acquire the affliction of violent behaviour from media, and in those cases, it will more than likely be found that the child suffers from other mental and social problems."

"Exposure to violent electronic media has a larger effect than all but one other well-known threat to public health."

I think this is a ridiculous thing to say. What about the effect of dangerous driving? People in Ireland would argue that it is massively more of a threat than violent media. It's practically unknown for a week to go by without one or more fatal crashes. How about the health effects from consumption of drugs? Alcohol? Crime? Poverty? No, apparently make-believe characters killing each other is more of a threat than all of these...

Also, 2 very misleading statements:
"Children are also spending an increasingly large amount of time playing video games, most of which contain violence."
Maybe most video games contain violence, but are these the games the children are spending more time playing? 2 completely unrelated facts, but it seems to connect kids and violent games.

"Video game units are now present in 83 percent of homes with children."
I would hope that he takes into account the responsible homes where the parents do their duty and monitor the kid's media intake. And the homes where the children are infants.
More BS junk science from Bushman, so why am I not surprised?

I'd like to know what kind of drugs Bushman is on, so I know exactly what to avoid.
I love the graph at the end that lists secondhand smoke, homework proficiency, and asbestos as some of the "top public health concerns" facing our society. Completely absent from the list are: cancer, diabetes, heart disease, and obesity. Honestly, I think more people today are dying from chipmunk attacks than asbestos poisoning.
@ nightwng2000

But don't you think there's at least some similarities in all of the studies. And granted all studies are not identical, but all scientific research are all unique and we're talking about social science, not physics. Of course, historical changes need to be taken into account and I think they already know that.

@ HandofCrom

It's nice to make comparisons to Japan, but there's huge cultural differences between America and Japan. So it's an iffy statement that you made. Studying what they watch isn't going to useful. It's how they interprete and make it.
Pants.
@ Janarius

But don’t you think there’s at least some similarities in all of the studies. And granted all studies are not identical, but all scientific research are all unique and we’re talking about social science, not physics.


Alright, they are similar. They all study the short term effects of media violence. This guy is taking that short term research and coming to long term conclusions. That does not fly in my book.

It seems to me that this guy hangs with John Bruce and we will see Johnny boy touting this as a huge victory for his side.

It’s nice to make comparisons to Japan, but there’s huge cultural differences between America and Japan. So it’s an iffy statement that you made. Studying what they watch isn’t going to useful. It’s how they interprete and make it.


Why should we take into account "how [Japan] interprete and make it." when we completely ignore how the US interprets and makes violent media. Violent media is violent media no matter where you go. I agree that we have different societies, laws, norms, and mores but that is something that all these researchers don't ever take into account.

I will be back with more after I read the whole thing.
I wonder how many of the studies he looked at were his own. He's been trying to prove for years that violent media causes violence...
This is it. This is the big one. The comparison of gaming to smoking. The same has been done for fast food and other lifestyle choices, and I have been waiting to see them try this tactic.
If this "new" research flies...which it won't. JT needs to enclude others in his faux lawsuits. He should not only include the video game industry but all the magor movie producers for producing violent and viral media...publishers of violent books, tv shows...the list goes on and on...how is he going to find the time to get all these people in before he gets disbarred?
You know, spewing out nonsense and claiming to be a scientist in the process is MUCH MORE dangerous than playing Halo 3 or Call of Duty 4.

Listening to this crap every day makes me angrier than any videogame ever could.
"...not every child who is exposed to this threat will acquire the affliction of violent behavior."

The affliction? I don't understand these people. They try to make out violent behavior like something that springs from the void, into the pure innocent, helpless child's brain, [i]injected[/i] by the vile media. None of these people seem to remember that violence is part of human nature. There were children bullying (and killing) other children looooong before video games were even conceptualized. Could it be that by indulging in violent media, we're satisfying a primal part of our nature, a part that would eventually scream to get out in other, much more [i]real[/i] ways? I think Disturbed's song "Violence Fetish" sums this up rather well, actually. Pacifism is a noble goal to strive for, but given our history, on a large scale, just untenable. Free will's a bitch, eh?

I can pretty much guarantee that if humanity were suddenly given utopia, say aliens come down and give us technology so advanced that not a single person goes without food or medical care, or even really has to work at all, we'd [i]still[/i] be finding reasons to kill each other. Without pesky everyday concerns, perhaps even moreso.
Doh. Apparently [] tags don't work here. Whoops. A habit from UBB forums I guess.
Now for what I think of the "study":

Different people may have quite different things in mind when they think of media violence. Similarly, among the public there may be little consensus on what constitutes aggressive and violent behavior. Most researchers, however, have clear conceptions of what they mean by media violence and aggressive behavior.


Different people have different interpretations of media violence, but all researchers are clear and unified in their interpretaion? Gotcha. I guess researchers are not people. Either that or there is a specific scientific definition of "media violence"

No reputable researcher is suggesting that media violence is the sole cause of violent behavior.


Yet he goes on and blames violent media and calls it the second most dangerous thing to youth health.

In fact psychological theories that explain why media violence is such a threat are now well established.


Yet they remain theories. They have not been solidified into fact.

Somewhat different processes seem to cause short-term effects of violent content and long-term effects of violent content, and that both of these processes are distinct from the time displacement effects that engagement in media may have on children. Time displacement effects refer to the role of the mass media (including video games) in displacing other activities in which the child might engage that might change the risk for certain kinds of behavior (e.g. replacing reading, athletics, etc.). This review focuses on the effects of violent media content; displacement effects will not be reviewed here, although they may well have important consequences.


Here he talks about time displacement or the act of replacing one activity with another. The examples he uses as replaced activities are interesting. Reading and athletics. Athletics happens to be some of the most aggressive and violent activity a child can engage in. I would think that athletics would have some kind of detrimental effect on children.

Reding on the otherhand can be calming and educational. But take a look at some of the most popular books with children and you will see a lot of violence. Harry Potter, Lemony Snicket, Spiderwick, etc.

Let me stop here for now so that this comment does not get too large.
Janarius,
Similar in the sense that most research doesn't focus on the INDIVIDUAL and the complex nature of individuals. They find what appears to be a common ground, determine a statistic, then sets that common ground as a stereotype for the whole of a particular group throughout the species.

"violent video games increase aggression". Therefore, people who play violent video games are statistically probable for being aggressive.

OOOOoooooo....

Except that the study didn't take into account a great many factors. Some of those factors include, but aren't limited to:

Genetic factors.
Personality types of the individuals.
Emotions an individual feels while playing
Life experiences of the individual which shape a great many factors over time. Experiences from the tiny forgotten type to the "life altering" events.
Mood of the individual at the time of the study.
Likes and dislikes for a form of media, a particular genre, a particular product.
Capability of playing a particular type of game or even a particular type of console.
How the individual reacts to a particular product.
How the individual reacts to other situations, interactive or non-interactive and WHY (using all the above factors in those situations as well).

But researchers don't care about nor do they record these factors. They ignore the complexity of these factors and their play on an individual at any given moment. These factors zip past us when they happen to us as well. "second nature" is a way to describe how we treat that complexity.

But the overwhelming majority of the studies being reviewed have the simplistic "they externally appear to be more aggressive, so the media/product makes them more aggressive". It doesn't matter how the study is performed and it doesn't matter the "side comments" they make. In the end, that's all these studies amount to. And doing a "review" on those studies does nothing whatsoever other than to support them by not taking into account those complex factors any more than the specific studies themselves do.

Is it possible to do a study on these issues? I truly think there is a very possible way to do a study on the issue of aggression in general and get far more realistic and intelligent data from such a study without leading to stereotypes of any group of individuals. And, quite frankly, I think it would be far more useful to the science of psychology and mental health than these limited misused studies have been.

Haven't you heard? Playing games and choosing to smoke a legal product are the reasons all of those things exist! Yes, even the asbestos! Damn anyone for enjoying something someone else doesn't agree with. :)
@ nightwng2000

Well I wouldn't say they don't care about the factors you mentioned, but i guessed they "controlled" these factor by having a large and diverse sample population, so people in the low and high extreme of a variable would cancel each other out.

If you look at Richard Tremblay's work, mentioned earlier. He only talked about genetic factors and nothing about social, emotional expression or social competence. So I wouldn't jump on saying he doesn't care about other factors.

Besides, doing a study to investigate all these factors would take a lot of resources and time. and for data analysis of this type, the result can be rather tenuous I think. (better ask my stats teacher)
This is it. This is the big one. The comparison of gaming to smoking. The same has been done for fast food and other lifestyle choices, and I have been waiting to see them try this tactic.

Yeah, they'll be doing it to everything...

First it's smoking
Then Trans Fat
Then Booze
Then Video Games
on and on and on...

But they are wrong - as usual - more JUNK Science. I play video games, from slow tactical types to fast violent types. It's actually a good place to get rid of stress.

What this clown and others need to realize is that many of us, have a very strong grasp of what is reality and what isn't.

Actually, what angers me more than anything is blatant stupidity pushing an agenda. And this study is chock-full of it.
I have more now:

Those who had played the violent video game were more physically aggressive toward peers. Other randomized experiments have measured college students’ propensity to be physically aggressive after they had played (or not played) a violent video game. For example Bartholow and Anderson [25] found that male and female college students who had played a violent game subsequently delivered more than two and a half times as many high-intensity punishments to a peer as those who played a nonviolent video game. Other experiments have shown that it is the violence in video games, not the excitement that playing them provokes, that produces the increase in aggression [26].


Its not the thrill of playing the game but the game itself that makes people more aggressive. It is not the fact that most violent games are very competitive and when you make someone play a competitive game and then make them perform a competitive agression test they will show more aggression to others.

Nope it is the violent content.

In summary, experiments unambiguously show that viewing violent videos, films, cartoons, or TV dramas or playing violent video games “cause” the risk to go up that the observing child will behave seriously aggressively toward others immediately afterward.


Hey look he is coming to a "causual" conclusion.

One more quasi-experiment frequently cited by game manufacturers should be mentioned here. Williams and Skoric [28] have published the results of a dissertation study of cooperative online game playing by adults in which they report no significant long-term effects of playing a violent game on the adult’s behavior. However the low statistical power of the study, the numerous methodological flaws (self-selection of a biased sample, lack of an adequate control group, the lack of adequate behavioral measures) make the validity of the study highly questionable. Furthermore the participants were adults, for whom there would be little theoretical reason to expect long-term effects


Translation:

"This study is directly related to what I am writing about and I have to include it. But since it does not support my preconcieved notions, it is completely flawed and therefore worthless."

Give me a break.

A number of researchers have suggested that, independently of the plot, viewers or game players who are already aggressive should be the only ones affected. This is certainly not true.


Here he is again debunking research that does not support his thesis. He has not facts to back this up, just his opinion.

That is all I have. Feel free to continue debunking and otherwise complaining about this "study"
Glad to see that the CDC is an expert on psychology and the neurosciences. Ha. Also, let's be clear on some science terms here. A theory is a number of hypotheses that have been well tested and has a great deal of evidence behind it. Theories exist to explain why the data is what it is. It cannot be a fact, as it is an abstraction, but a true theory is considered fact. What this guy is talking about is a hypothesis. A hypothesis is just a guess at why something is the way it is. It may be true, it may not.
This is it. This is the big one. The comparison of gaming to smoking. The same has been done for fast food and other lifestyle choices, and I have been waiting to see them try this tactic.

I've been waitng for them to try this too. Once you say something is almost or just as bad as smoking - the big public health boogeyman - everyone's alarm bells go off. The only problem is smoking has major, demonstrable and physically tangible effects while the media violence is far more nebulous. They're really reaching here as the comparison is fallacious on a lot of levels. As Overcast said, it's just more junk science.

Also, how much does anyone want to bet that certain politicians - especially those running for president - (*cough!*Billary*cough!*) will pick up this ball and run with it?
You know, considering that 83% of homes now contain violent video games, yet much less than 83% of children act aggressively, you'd think they'd look at the other factors.

Wishful thinking, I suppose.
Janarius,
I do like the genetic research study as it does focus on another of those many factors. But it's still limited.

And when researchers make the argument about how much time and resources it takes to do a more thorough study, the word that seriously comes to mind first (and maybe a little biasedly): lazy.

Frankly, when it comes to studies that rely on such complex issues and so heavily on chaos theory as well (dang that uncertainty principle!), I hold very little interest in statistics. I'm not even a big fan of profilers because more ofen than not, we'll hear about successes but not how often they may be wrong. I keep having this image of the so-called "professional" who made all sorts of claims about the Branch Davidians in Waco... but had never met a single one and couldn't really back up any of his claims with FACTS.

Statistics have their uses. Unfortunately, too many folks love to use, or rather MISuse them, to create idiotic stereotypes about many groups of individuals.

I do believe there ARE good researchers out there. But like so many other good people in various professions, they get ignored in favor of the bad sensationalistic ones.

It's the attack of the buzz words! Exposure... risk... heavy violence... threat... public health... smoking... cancer... saturated... detrimental effect... affliction... control...

Scary medical terms are coming to mind: containment, euthanasia, sterilization, quarantine, vaccination, treatment, infection, contagion...

Soon there will be a new STD called VGA: Video Game Aggression. Remember, kids: if you have sex with a gamer, you're playing all the games they've played before.
BTW, that's pronounced "veeguh" or "The Veegs", for short.
Wow... this is really monumental research. I mean, if children weren't exposed to violent media aggressive behavior would be abolished. Children would stop mocking other children that were different from the accepted social norm. They wouldn’t hate someone for having different religious views or show bias against them for the color of their skin, mental capacity, or physical appearance. Yes, this study obviously proves that without violent media the world would become a utopia of peace and harmony.

We all know it’s true.
I like how they keep going on and on about the violence present in media and how playing violent games and such can increase AGGRESION (ie, not violence) but they never actually say what the actual 'threat' to one's health is. They just compare it to tobacco without actually SAYING what the health threat is.

Tobacco = Chemical that withers away organs and kills human beings.
Video Games = Media taken in through senses.

Last i checked, images and chemicals are not the same thing.
@ DavCube

Although not expressly concluded to in the article, the health haard seems to be the possible violent actions stemming from the aggressive behavior. He cannot prove that people who are more aggressive are more violent. But they can make that assumption because they are researchers and what they ay goes.
I'll put it bluntly: this research is shit, mainstream media are flies. Of course the media will notice this study, and give ALL researchers a bad name by attracting attention to it.

Serious studies don't get 10% as much attention as they deserve. Facts don't sell nearly as well as fear, but that's certainly nothing new.
Wow... Just... Wow...

@ EZK

Excellent analysis! Thanks for those points you mentioned. That's extremely helpful and points to the LARGE black hole in his summary argument and conclusion...

...lack of numbers.

Not once do you see him conclude with percentages or references to past studies and the number of subjects who were showing extra aggressive tendencies.

"As with many other public health threats, not every child who is exposed to this threat will acquire the affliction of violent behavior. But that does not diminish the need to address the threat — as a society and as parents by trying to control children’s exposure to violent media to the extent that we can."

Without statistics or facts to define how many exposed children will show violent behavior (as if children aren't violent because they haven't matured enough to understand how to express their anger in other ways SHEESH) this becomes nothing but propoganda. Unless he can show facts behind this "study" it's nothing more than theory and speculation PROBABLY to get the CDC and gov't to fund a project to try and prove a link. This smells like maneuvering for funding to me and nothing more.
@ Loudspeaker

No problem. Simply doing my duty as a concerned and informed individual.
There seems to be a correlation between the laxity of a country's porn laws (and almost inevitably as a result, the freakiness of their porn) and a lower reported rate of sexual assaults. I don't really think it's relevant, but it's interesting to consider.

I do think the media we consume affects how we behave. But I don't think it is useful to count up violent images as if all were the same, and think you have collected meaningful data that can be used to draw conclusions. I think the problem is not violence itself, but how it is presented.

It would not surprise me at all if it were true that neighborhoods where professional wrestling is broadcast have more schoolyard injuries than similar neighborhoods where it isn't. In fact, it would surprise me if that wasn't true. The message of professional wrestling is, "We are cool! Consume us over and over! We give you a buzz you can't get anywhere else! Woohooo!!"

However, depictions of violence can have exactly the opposite effect to what is usually described. Just like real violence, a depiction can make you more sensitive to future depictions of violence. Does Bambi make you want to hunt deer? Does Brokeback make you want to stomp queer? ... oh god, excuse me. I'm a horrible person.

The problem isn't violent media. The problem is junk media.
Loudspeaker, you're right on. There are no numbers whatsoever- numbers are the cold, objective elements of a scientific study. It's better to say "16% more" rather than "somewhat more" because "somewhat" is subjective.

I just have to say...don't they teach you the scientific method at school anymore? The most important thing about conducting experiments is putting variables into account (like the different moods of the people at the time of the experiment, and their family values).
Let me guess, he was one of the idiots that claimed junk food was turning our kids fat?
Reviewing 50 years of research is only likely to prove one thing: People love to scapegoat things. Whatever happened to finding the screams that went off from Elvis' gyrating his pelvis?
Consuming media is no where near threatening unless it is done without moderation. Then this just is as simple as any other form of entertainment as there is some risk of no moderation for many things in life.
Humans are naturally aggressive, and still trying to put blame that something will increase aggression is just silly. The testes increase aggression first and foremost, I'm glad they haven't gone with worldwide castration attempts; idiots.
A real threat should be idiocy coming from this guy, because spreading disinformation can cause many other problems than (like actual acts of murder) simply increasing aggression.
Wait a minute, I can't believe that L. Rowell Huesmann, Director of the Aggression Research Program, and Editor of the Aggressive Behavior journal found that something causes aggression???
Next you are going to tell me that the president of the state lottery commission thinks that people spending money on lottery tickets leads to people being millionaires!
Call me cynical but anyone who has affiliations with so many things that have "aggression" in the title seems highly unlikely to say, "Nope, we looked at it and it doesn't have anything to do with aggression."
IANAS (Statistician), but the overall appearance of this study looks... questionable. It looks a lot like he's attempting to attribute rare effects to a very common causes. Sort of along the lines of "All drug dealers wear Fubu jackets, therefore Fubu jackets make you deal drugs". Anyone see how that works?

I'd be much more curious to see this tied (or tried to be tied more like) to actual incidents of violence. Doubly so by including it with several other, more well known and less mentioned causes IE poor family structure, social marginalization, levels of abuse (physical and mental) and so on.

Unfortunately, statistical studies are a right bi**c to handle, and without a -large- base pool, it can be hard to make any actual conclusions. As well, unless one is careful to include all income levels and social situations, some kind of bias will exist.

Which goes to prove that statistics can be used to prove anything.
"As with many other public health threats, not every child who is exposed to this threat will acquire the affliction of violent behavior."

Erm. Isn't this wrong? Isn't a public health threat by definition something that does have an effect on everyone? Not everyone is affected seriously, but nobody gets away clean; not all smokers will get lung cancer but smoking will damage your lungs in some way.

Interesting theory time! A small percentage of people exposed to X will exhibit negative effects as a result of the exposure. Therefore X is a public health threat. In this case, the statement is X = games.

Let X = nuts.

So could it be that some people are, in a way, mentally allergic to games?
Sweet mother of the gods. The world is ending and it all due to the evils of media. War, plague, pestilence, and famine must all be servants of the Great Media. The one power destined to rule humankind or destroy it.

.... sorry but this was a button pusher.

Guess it is safer to sit in your garage with your car running and the doors shut, dodging in front of a student driver or going to war in Iraq, then to be near the mind controlling media.
Admittedly well over half the households in the US have at least one game playing device (I have 4 just for myself) but this is historically the way of things. When televisions became affordable they were in the majority of homes. The again so were clothes washers but I cannot remember anyone complaining about those even though there were related injuries. It would seem that everything that cannot be strictly controlled rots the minds of the user (especially the kiddies, must save the kiddies)

The "report" was compiled from 50 years of other reports. Odd that I cannot find anything in there saying of the checked reports had anything to do with Media nor that he checked and used all available reports.... ie he picked and chose (for all we know he could have been using JBT's book or some other game hater). His bias is much at the heart of the issue and should be considered.
Use what you want and ignore the rest.

At least he admits "not every child who is exposed to this threat will acquire the affliction of violent behavior" What he kind of forgot to mention that is it not even a majority. Take a few and just a really paintbrush so you can paint out a picture about All.
Here is a link to the journal that JCCalhoun mentions:

http://www3.interscience.wiley.com/journal/32356/home

Seriously, roll down and look at the list of articles in just that one issue.

Look at the first line in the abstract for the article "Young adults' media use and attitudes toward interpersonal and institutional forms of aggression":

"Links between media violence exposure and favorable attitudes toward interpersonal violence are well established..."

Really? Where?

What I want to know is: is the increase in agression enough to make a nonviolent person violent? Can the researchers like violent media as the primary cause of any particular act of violence?

What is it, Lassie? The connection seems to only be teneous at best? For all their fancy degrees, these researchers still haven't determined a causal link between a short-term increase in aggression and a long-term likelihood of violent behavior? Nobody enjoys violent entertainment in a vacumn, and thus other factors should be taken into account when a study linking it to ANY behavior is conducted? Good girl, Lassie!
I asked Dr. Christopher Ferguson who previously wrote journal articles on video games, and he's mentioned in GP too. and here's his responses to my inquiry about this news:

I'd have to disagree entirely with their conclusions. The research on media violence in general has been very poorly done, as other scholars have noted (Freedman, 2002; Savage. 2004). Briefly, major problems include the use of unstandardized, unvalidated measures of aggression, the tendency to ignore negative results in a manuscript and focus only on positive results, and the failure to eliminate "third" variables such as family violence, genetics or personality. These are widespread failures in his field, and as such it's impossible to really assess much of value from the field as it exists.

The statement that media violence exposure risk is close to that of smoking and lung cancer has been debunked. The effect size for smoking and lung cancer is (r = .9), (Block & Crain, 2007) not (r = .4) as once claimed (Bushman & Anderson, 2001). This larger figure is supported by the American Cancer Society's data noting that 87% of lung cancers are directly attributable to smoking with a relative risk of 23 (meaning smokers are 23 times more likely to develop lung cancer than non-smokers).
The effect size for media violence on violent behavior (even if you ignore all the significant problems I mentioned above) is (r = .1). There are many, many, many, many risk factors in life that are of much greater effect than media violence exposure.

and when I asked him about Block & Crain (2007) about the effect size and whether there was a response to their criticism:

Yes they responded, but not adequately in my opinion. They replied that they couldn't replicate Block and Crain's statistics...although I can't understand why not, as I could replicate them easily enough (in fairness, I can replicate how Bushman & Anderson, 2001 get their very different results too...it's just that their technique is not very good for converting medical data to psychological effect sizes). Despite Bushman & Anderson's response (2007) the data used in most medical studies can not be converted into the effect size r (Rosenthal & DiMatteo, 2001). My observation is that attempts to do so greatly truncate the observed effect size...which looks good to psychologists who want to think that our effects are as good as those seen in medical research...but they just aren't as even a little digging can reveal (I encourage anyone to read the American Cancer Society's statistics on smoking and lung cancer and see if they'd agree that 87% of violent acts can be attributed directly to media violence as is the case for smoking and lung cancer).
Did GP (or someone else) modify Huesmann's photo or is he a midget? His head is hugely disproportionate to his body size. Perhaps birth defects can be added to his list as a third public health threat?
What, we're only in second place? We should go after those filthy smokers and claim the top spot! I don't play video games to get silver medals.
@Simon Roberts
lol

@janarius
I like what he has to say, but can we get links to these studies?

Seems like these guys (Huesmann et el) are making the facts fit their theory instead of making their theory fit the facts.
@ Jon

"Honestly, I think more people today are dying from chipmunk attacks than asbestos poisoning."

Or at least RADON. Asbestos is generally considered a lung cancer risk, but has become less and less of a problem because it has not been used in home products for quite some time. RADON also causes cancer. However as it is a naturally occurring radioactive gas found in most basements around the USA. Also it is actually more dangerous in modern / well insulated basements because the insulation traps it, and causes it to concentrate into higher (and more toxic) levels.

This is why the Government already considers RADON the second leading cause of lung cancer in the USA.

Seems like he chose asbestos because it was more recognizable, which further reduces his credibility. It was already low I think, as years of violent media has made me fearful of 'mutants'...
This study is pretty poorly written and seems to lack an appropriate amount of professional detachment. I also wonder about the ethics using a literature review of mostly one's own research to seemingly push an agenda. Almost half the sources he uses are himself or his colleague Bushman and all the sources that seem to deal with the long term effects are by Huesmann and Bushman. Also there is the simple problem with long term studies, which is they tend to have a high attrition rate. The people who stay in the study may have a confound relative to the ones that refuse to continue the study. For example, depending on what incentives were offered to participate in the study (sometimes money is given to participants in studies), the ones who participated may confound the study due to similar socioeconomic status. Also, the longitudinal studies are correlational, which means that violence could cause the interest in violent media, violent media could cause violent behavior, or other factors could cause both. Additionally, the correlation is relatively small.
So... based on this I should be out on a killing rampage right now instead of writing comments here. Sounds logical. *rolls eyes* Not very trustful that the CDC is clamoring behind this, considering it's tied to an administration that's socially backwards. Oh well...

~Sol~
Meta-analysis, the act of studying masses of other people's work to try and find correlating patters, is notoriously inaccurate. It rarely works, and the chances of wrong conclusions is huge.

Unless Mr. Huesmann can come up with his own double-blind study that shows media violence = actual violence his "study" is complete bunk.

Move on.
So they are saying that increasing RISK is the same as a CAUSE and EFFECT? You have a high risk of dying in a plane crash when you get into a plane just like you reduce that risk when you drive in a car... of course you are increasing your risk to die in a car crash. Does not mean you WILL, just the risk of it increases. In other words, this study is blatant missinformation between the facts and the interpritation. In short:

Just because you increase the risk does not mean it is going to happen.
Oh, so we should get rid of things which increase aggression then? Does that include peewee sports teams?
@ Erik

No we should simply ban parents from the games. ;)
I have only three words to say: What the f***?
I sometimes wonder if they even realize what they're saying, because if any of this was true, we'd be a country of mass murderers.

And THAT'S what makes me laugh each and every time someone makes the claim that by simply taking in some form of violent media it makes anyone extremely close to becoming a violent person.
Hilarious. Simply hilarious. One could make the same corollary argument about running water in the home given the ubiquity of televisions and video games..

But, yea, if video games increase violence, shouldn't there be, oh, I dunno, an actual increase or something? Because according to the DOJ, "Since 1994, violent crime rates have declined, reaching the lowest level ever in 2005." Doom came out in mid-December of 1993. If we're to ignore all other risks and socioeconomic factors involved like this guy pretty much just did, it looks like an inverse correlation to me.

Can I has a brazillionty dollar research grant? ^_^
The research clearly shows that exposure to virtual violence increases the risk that both children and adults will behave aggressively…

Then why have only two of the people who have attacked me outright over the years been gamers of any kind?

More than 60 percent of television programs contain some violence and about 40 percent of those contain heavy violence.

1: Those percentages are inaccurate.

2: Violence on T.V. became irrelevent when the ability to block any channel you want became available.

Children are also spending an increasingly large amount of time playing video games, most of which contain violence.

I love when these people don't specify what they mean by "children". The term can easily refer to anyone under 18, or a specific age group, let's say, 5-12.

Video game units are now present in 83 percent of homes with children.

I don't know how accurate that is, but it's irrelevant regardless.

Exposure to violent electronic media has a larger effect than all but one other well-known threat to public health. The only effect slightly larger than the effect of media violence on aggression is that of cigarette smoking on lung cancer.

Buuuuuuuuuuuuuuullshit.

Our lives are saturated by the mass media,

Wow, he actually stated something true.

and for better or worse, violent media are having a particularly detrimental effect on the well-being of children.

Only if said children are being raised by the family television, which is not the fault of anyone in the media.

As with many other public health threats,

Violent media isn't a public health threat.

not every child who is exposed to this threat will acquire the affliction of violent behavior.

Vilence isn't an affliction, it's a part of human existence. Always has been, always will be.

But that does not diminish the need to address the threat — as a society and as parents by trying to control children’s exposure to violent media to the extent that we can.

That's quite easy, unfortunately, most people aren't up to the task.
@jon

Honestly, I think more people today are dying from chipmunk attacks than asbestos poisoning.

I'm sure the people in their 70s that currently have their lives threatened by cancer caused by asbestos like my grandfather would be overjoyed to hear that it could be worse, they could be chipmunk attack victims.

@Gavin Schmitt

Asbestos is generally considered a lung cancer risk, but has become less and less of a problem because it has not been used in home products for quite some time.

The thing is, the people at the most risk are those that worked in industrial settings. Worked on ships, worked on car brakes, worked on duct work in old buildings. Not home products. Since there are still a hell of a lot of old buildings around that have asbestos in I'm sure we'll be seeing plenty more problems from it for some time to come. Particularly with the poor immigrant workers hired to work on some of these old buildings that have no idea of the dangers, and whoever does the laundry at their house.
"support of the U.S. Center for Disease Control and Prevention (CDC) concludes that media violence - including video game violence - is an emerging public health threat second only to smoking tobacco."

20,000 people die in drunk driving accidents every year and the second emerging public health threat isn't alcoholism but them there vidya games and them movin' pictures.
Oh, and is heart disease heart attacks lower than smoking related cancers? Don't think so.

Not to mention the leading cause of death in America is still "bullet-to-the-abdomen-itis".
So these tests in which they gauge aggression how many of their test subjects killed/attack someone? Or is this where they use nerf bats or sound blasts as simulated aggression and somehow correlate that to real world violence.

Aggression is not a bad thing. An aggressive salesman will win out over a passive salesman. I don't want to see that video games cause violence, because frankly there are a lot of people who need to be more aggressive (as society at large seems to be getting sorta wussy), what I need to see is that playing video games somehow negates a person's moral limits.

Aggression is a normal human emotion.
I really wish I could pose this question to these researchers; How, if violent media makes people violent, has violent crime among youths actually DECREASED over the passed 20 years ?
This study is just crap. First of all, the conclusion seem exaggerated. The thought that violent media is worse than a nuclear disaster (Chernobyl, anyone?), natural disasters, non-tobacco health dangers, and even al qaeda is jacked up. These people, with all due respect to them, must have a bias against said media. Secondly, they didn't consider genetic factors as well as poverty, how the child was brought up, and that child's education. These factors are essential. Finally, agression NEVER equals violence. It CAN lead to violent acts, but aggression does not automatically cause violence. Saying that violent media increases aggression isn't satisfactory for the courts.

In the end this study just doesn't show the casual link and other important factors were not even taken into cosideration.

One more thing:
Like Erik said: Aggression is an emotion.
This flawed study brought to you by: The people for the pussification of todays north-American youth.

Thats right, these are the kind of people that think ALL aggression is bad and todays little boys and little girls should be enclosed in a plastic bubble and fed trite mental pablum well into their twenties.

I just love social engineers. I'm glad that I am the one in charge when it comes to what my kids will see and hear(Mostly, y can't watch them 100% of the time Just look at Jack Thompsons little sob story about how his sisters boy went over to a friends house and played GTA and thats why he's after Rock*). These jerks will have to step over my cold, dead body to take that right and responsibility away.
*This public service announcement from your good friends at CDC*

There has been an outbreak of a disease in our building. The disease cause people to lose all common sense and rational fault and blame very complex problems on very benign things, like say kleenex or video games. Please don't be alarmed as other than a very strong dose released in Washington D.C. and a small part in Miami there has only been a small amount of the virus that has managed to escape. While it may ahve infected some of our hospital staff, please don't be alarmed and don't listen to them either as they are not in the right state of mind. We are currently in the proccess of containing this virus and will most likely do so before the situation gets worse.

*Thank you for your time*
Oh and they don't call it JOINT research for nothing, that's actually how they draw their conclusions.
Wow I didn't know violent media could actully hurt somone that must be true! By now you will relize I am not serious and find it hard to belive these people. Oh yeah did you know a study in 2000 said games caused aggression, but they used the games Castlewolfenstien 3D and Myst, two different genres, and only allowed 15 minutes of play time.

-DarthCylon
Wait a minute first the study says this.

"Violent or aggressive actions seldom result from a single cause; rather multiple factors converging over time contribute to such behavior. Accordingly the influence of the violent mass media is best viewed as one of the many potential factors that influence the risk for violence and aggression. No reputable researcher is suggesting that media violence is the sole cause of violent behavior."

Then go on to compare violent media to cigarettes? It boggles the mind how stupid some people can be (and this is supposed to be a proffesional report too).
For those of you not familiar with Huesmann, he did a study that many politicians love to cite, but like all others, has Swiss cheese methodology. He was the one who did the longitudinal study measuring 8-year-olds, and showed that viewing habits back then were positively correlated with violent crime at age 30. This study, of course, had the problem of a high dropout rate, leading to all the data coming from the violent crimes committed by only 3 subjects. Huesmann himself admitted that if not for those 3 boys, there would be no significant statistical finding.
Wow they also contradict themselves in the next two sentences.

"Most youth who are aggressive and engage in some forms of antisocial behavior do not go on to become violent teens and adults [1]. Still research has shown that a significant proportion of aggressive children are likely to grow up to be aggressive adults, and that seriously violent adolescents and adults often were highly aggressive and even violent as children [2]."

So they say most aggressive youth do not become violent adults but aggresive adults? That right there basically admits that aggression is not equal to violence which SHOULD support our side. Then again they say most violent adults and teens (well not even most but a significant portion, the article was written in 1984 and I can't find a copy) used to be aggresive. But wait 2 sentences earlier they said most aggresive youths don't become violent. So they both admit aggresiveness does not equal violence and point out that correlation does not equal causation in 3 sentences without even meaning to, (both of which are points for our side). What geniuses.
And of course the whole graph is based on Correlation. So he's basically saying there's a bigger correlation between violent media and real violence than exposure to lead and low iq scores in children. Of course any idiot will tell you that correlation does not equal causation.
There is no denying that we are all influenced in some way by the media we consume, but that is a Superman sized leap to turns a kid into a killer.
"The best single predictor of violent behavior in older adolescents, young adults, and even middle-aged adults is aggressive behavior when they were younger. Thus anything that promotes aggressive behavior in young children statistically is a risk factor for violent behavior in adults as well."

Once again he contradicts himself here when before he said most aggressive kids do not grow up to be violent (and come on how many little kids do we know that love to knock over towers made out of blocks and have pillow fights). Not only that but anything that promots aggressive behavior? I could think of some board games that promote aggresive behavior within the games. Also as pointed out before, msot studies only show the short term effects. This means that if it promotes a short term aggresive behavior that wears off quickly that suddenly means they'll grow up to become violent. Such heavy bullshit.
"In fact psychological theories that explain why media violence is such a threat are now well established."

Aye so are the theories of how the government did 9/11 and how they faked the moon landing. Remember they are theories.
"Furthermore these theories also explain why the observation of violence in the real world—among family members, among peers, and within the community—also stimulates aggressive behavior in the observer."

Ahem. The sun rotates around the earth. This explains why the sun sets in one direction and rises in the other.

And again he is saying that aggresiveness equals violence which as he just proved earlier is not the case. he just proved was not the case Don't you just love it when people destroy their own arguments for you?

The fact that this guy even brings up displacement effects (e.g. the effects of playing video games instead of reading or doing something productive) makes him seem biased and makes his arguments seem more well pathetic.

I'm not even going to bother responding to the rest of his arguments since they destroy them selves (this paper will self destruct in five seocnds).
http://www.ncjrs.gov/pdffiles1/ojjdp/218587.pdf

Most of the case numbers are plateauing and have been moving up since 1962, thus meaning video games aren't to blame...
"But that does not diminish the need to address the threat "

*sigh*

And that's what ratings are all about... Protecting people from harmful material.
@ Janarius

Not much to say but DAYUMN, very well done.
ok...but what about the news???

The news has real violence but it is on daily.

What about the impact of violence in news on regular people????
@ TBoneTony

Dunno about you, but I just stop watching it unless there is somthing specific on. Theres always more interesting news on teh intertubes anyway.
we are expose to violence every freak in day..... god...... what the hell is worng with people.
Hey kids, here's a fun game you can play with all of your friends! It's called "Cherry Picker", and it's a real hoot!

Here's how to play:
1) Pick a conclusion that you want your "research" to come to.
2) Throw out any facts or evidence that don't support your conclusion.
3) If you don't have any facts or evidence left after step 2, no problem! Just make up some crap on your own!
4) Publish your results claiming them to be scientific facts.
[Optional] 5) Question the character, patriotism, or even sexual preference of anyone that disagrees with you.

Now you, too, can blame all of todays problems on whatever it is you don't like or understand, and even start wars for fun and profit!
Wow, yet another highly paid puppet. Just what the world needs.
My apologies, i realy need to elaborate more on my comments:

“The research clearly shows that exposure to virtual violence increases the risk that both children and adults will behave aggressively… More than 60 percent of television programs contain some violence and about 40 percent of those contain heavy violence.”

Honestly, how much are these bozos paid to stand on a soapbox and cite false statistics and somehow, by the skin of their teeth, attribute the violence in youth to video games? That, and they also fail to recognize that violent video games ARE NOT TARGETED FOR CHILDREN!

“Our lives are saturated by the mass media, and for better or worse, violent media are having a particularly detrimental effect on the well-being of children.”

Same argument was stated decades ago when television was introduced buddy.

Bottom line, idiots like these need to get their eyes off their pocketbook, get off their soapbox, and pull their heads out of their asses. They couldn’t convince anyone then, and they sure wont convince anyone now.
[...] Dass Videospiele die Wurzel allen Übels sind, ist ja bekannt. Deshalb überrascht eine neue Studie, die behauptet, Videospiele machen aggressiv, keine wirkliche Überraschung. Allerdings schließt diese Studie daraus, es handele sich um eine Gefahr für die Volksgesundheit (Public Health), da Videospiele extrem deutlich (statistisdch hochsignifikant) zu gewaltbereitem verhalten führen. Wenn man sich jetzt anschaut, dass laut dieser Studie 83% aller Kinder Zugang zu gewalttätigen Medien haben kann die Signifikanz aber nicht so hoch sein wie behauptet, denn dann wäre in Amerika bereits die Zivilisation zusammengebrochen. Interessanter ist da schon, dass Videospiele jetzt auch für Analphabetismus verantwortlich sein sollen. Zumindest laut der britischen Tageszeitung The Sun, das dortige Gegenstück zur Bild, die erst am Tag zuvor mit nackten Mädels als Werbung für das Videospiel Need for Speed Pro Street Auflage gemacht Aufmerksamkeit erregt hat. Tja, gestern so, heute so. Die Bundeszentrale für politische Bildung empfiehlt unterdessen Rollenspiele (explizit genannt wird Pokémon) fürs Lesen lernen. [...]
