Intro:
Since the attacks of 9-11, there has been an increase of interest in both the general public and the scientific community about the effects of religious belief on violent behaviour.
In the past, there has been research that has shown a link between experiencing violent media and aggressive behaviour. Further replication of these studies found that the aggression was increased if the viewer identified with the individual committing the violence (such as seeing a soldier from one's own country, or supporting a cause they believe in, kill an enemy of that country/cause). Aggression also in increased in instances where the violence appears to be justified (A man kills another man for sleeping with his wife). This has been studied primarily in TV and video game media, however, little has been studied about the effects of written word on this aggression.
Before I explain the Hypotheses, I want to linger at this. By saying "experiencing violence increases aggression" nobody is saying that playing violent games or watching violent movies makes you violent. No real scientist would promote the idea that games or TV make kids violent and aggressive the way the media promotes, but, there are studies that show odd trends. If this is a major issue of contention to people we can go over it more.
Anyways, given what is known about media effects on aggression, the authors posed 2 hypotheses:
1) Greater aggression will be seen in people exposed to a Biblical description of violence than those exposed to secular descriptions of the same violence. (Identification increases aggression)
2) Aggression will be greater when the violence is sanctioned by God than when it is not. (Justification increases aggression)
The experiment was then divided into two identical studies, one done at Brigham Young, the other at Vrije Universiteit.
Study 1:
-248 American Students, 95m 153f
-99% Believed in God and the Bible
-97% Members of the Church of Jesus Christ of Latter Day Saints
Study 2:
-242 Dutch students, 110m 132f
-18% Catholic
-11% Protestant
-12% Muslim
-8% Christian (I suppose other than Catholic or Protestant, or didn't specify)
-2% Hindu
-1% Jewish
-8% other
-40% no religious affiliation
-50% Believed in God
-27% Believed in the Bible
Procedure
Each Study was then divided into 2 groups. One of these groups would read a biblical description of violence (Judges 19-21) whereas the other half would read the same description as if it were a scroll that had been found in an archaeological dig in 1984. The hope was that people would not necessarily recognize the obscure judges passage instantly as being biblical. There is no evidence that it did not work.
The story involves a group of people avenging the rape and murder of a woman of their faith by destroying a village and starting a war that eventually left thousands dead.
There was then a second manipulation, for half of the people in both the biblical and secular violence groups, a passage that specifically had God justifying this violence was added.
This first part of the experiment is based on the idea of subconscious priming. This is something that has been shown to produce reliable results in the patterns of human thinking. By presenting people with words or pictures, you activate every single memory that the person has associated with that idea, only the most salient and relevant one gets through to conscious thought however. But, even though you never consciously thought about those other things, they are still "primed", meaning that they will be more accessible to conscious thought than they were prior. So, say you are a fan of the Ali G show. Now me just saying that name, whether you are a fan or not, has primed all of your memories of that person. It is likely that you have thought of Borat, maybe some of his anti-semitic remarks. Possibly you would be more likely to tell a marijuana joke, or laugh about Butros Butros Gali's name. The same principal is at work here. Even though people are not consciously enraged or angered by what they have read, they would be more likely to make aggressive decisions or show aggressive behaviour due to it being primed. Again the hypotheses being that 1) the biblical description of violence will have a greater effect on the priming of aggressive behaviour and 2) the sanctioning of violence by God will increase the priming of aggressive behaviour.
In the second part of the experiment, subjects are lead to believe that they are competing in a response time test against another person. Each time they lose, they are blasted with noise over earphones. However, when they win, they believe their opponent gets the same. There is also a 0-10 scale by which the subject is able to determine the level of violence that his opponent hears when they lose. 0 being no noise, 10 being a quite uncomfortable blast. Aggressive behaviour in this experiment was described as using the 9-10 level. In reality, the subject is being tested at random intervals against a computer. There are trials the subject cannot win where they will be blasted with a random level of noise, thus very rarely the highest levels (20% odds).
While this may seem a hardly relevant test of aggression, please remember, scientists aren't aloud to indoctrinate children into extremist ideologies to see what the effects are. These experiments have been shown as reliable demonstrations of human aggression.
Results
Study 1 - Brigham Young University
People reading biblical passages were more aggressive than those who read secular passages.
People who read violence justified by God were more aggressive than those who read unjustified passages.
Men were more aggressive than women
Study 2 - Vrije Universiteit
Those who believed in God were more aggressive than those who did not although in both believers and nonbelievers, depictions of violence justified by God increased aggression.
Secular depictions of violence, whether justified by God or not, showed no different between believers or nonbelievers in aggression produced.
Men who believed in God were more aggressive than those who did not when God sanctioned the violence. Whereas women were the same regardless of whether God sanctioned the violence or not.
