Politicians often blame video games for some of the violence in our world, and while it is true that the top five most popular video games right now are all shooter games, do the guns on screen really translate into aggression in real life?

Can video games make you violent?

One of the main arguments people make against video games is that they prime kids to be violent.

Priming is a non-conscious form of memory where one stimulus influences the response to a subsequent stimulus.

For example, if I said the word yellow then asked you to name a fruit, you would most likely say banana.

This led to a study in which researchers had participants play one of two games.

One game where they were in a car avoiding collisions.

Another where they were just a mouse avoiding a cat.

Following the game, the researchers, based on priming, hypothesized the players would be faster at categorizing objects associated with the game they played, more quickly in the real world.

So the players looked at pictures of things like a bus or a dog and were asked to quickly label them either as a vehicle or an animal.

Those who played the car game were no faster at categorizing vehicles.

And those who played the cat game were no faster at categorizing animals.

In fact, those who played each game had a slower reaction time to the related category, meaning negative priming might actually be occurring.

Oh, science, you're always just messing with us, aren't ya?

But unlike the 8-bit games of our past, today's game designers are capable of producing incredible graphics.

Therefore, another criticism is the more realistic a game, the more likely it will activate aggressive behavior.

To study this concept, one study had participants play one of two combat games, one where the characters were modeled using rag doll physics - movements modeled off of the human skeleton, which means they had very physically realistic death behaviors.

The other game used deaths that were extremely unrealistic.

Afterwards, aggression was assessed via a word association test, and the game with the more realistic deaths showed no increase in aggression.

Of the available research, most find no link between video games and violence.

A meta-analysis of studies showing a positive link between games and aggression found that they often used ineffective lab tests of aggression; for example, measuring brain waves and heartbeats, which doesn't necessarily translate to actual criminal behavior.

And in the past, when a correlation has been found, it's been weak.

Criminologists who study mass homicides refer to the link between violent games and crime as a myth.

In fact, in 2011 the US Supreme Court ruled that research did not find clear connection between violent video games and aggressive behavior.

Unfortunately, we all know how often after a crime, video games and violent media get brought into the conversation, but the truth is this might actually be distracting from the more significant causes of violence.
