| The much-cited Milgram experiment of 1961 suggests the answer might be yes.

| If violence wasn't such a kick for people war would not exist. We may not like to admit it, but war is attractive for a lot of people. The primitive tribal side comes out and people often find it hard to settle back into "normal' society after the kick of war. Only when we have emotionally developed will we learn to curtail our violence instincts.John Murphy, Amsterdam | |
| I KNOW that I am capable of violence and it scares me, particularly as with Army & martial arts training I could mete it out effectively. But I also choose not to react violently, partly because I know I could if it became necessary. That's the key: 'Necessary.' Not because something or someone has annoyed me, but because my life or that of someone else is threatened and the only recourse is to use violence in protection.Megan, Cheshire UK | |
| There's a very interesting alternative perspective to this in "On Killing: The Psychological Cost of Learning to Kill in War and Society" by Colonel Dave Grossman. He argues, backed by a lot of convincing historical evidence, that most people are intrinsically reluctant to kill others. However this reluctance can be overcome by appropriate conditioning. Unfortunately, one of the best ways to do this, is to condition people by exposing them to realistic violent computer games, rather as many teenagers are administering to themselves nowadays.Alan Y, Oxford, UK | |
| The proposition that we are [all?] born to be violent is spurious and/or irrelevant because the vast majority of us for the vast majority of the time [if not all of the time] are not violent. The question is not 'why are people violent?' but 'Why are SOME people not passive?'. Psycho-social experiments examining violence have tended to generalise from small scale non-naturalistic settings. Historical examples of mass violence have to be understood in terms of the cultural contexts not the behaviour of individuals. Neuroscience is not only in infancy in this area but has major problems in separating cause from effect and in sampling. Moreover, the issue of actual violence can and perhaps should be de-coupled from that of fascination with violence. Dr Peter Morrall, York, UK | |
| There is much research both within the social sciences and beyond (population genetics, for example) studying the innate basis for altruism. Articles such as yours give a one-sided picture when they do not address the other side of the coin. There are just as many biological arguments for the empathic, cooperative side of humanity. A case in point for the potential bias caused by not seeing this, is your citation of Milgram. The whole point of that experiment, was that authority can make people do things they emphatically DON'T want to do, and indeed avoid doing without immediate authoritarian influence. Milgram reports two participants having full-blown seizures, because of the stress caused by the conflict of interest. You are misrepresenting Milgram's work by using it as evidence for innate bloodthirstiness - Milgram himself was in fact arguing the opposite and blaming obedience to authority for the expression of aggression.Ben Brown, Brighton | |
| I'm honestly surprised this could be considered news. The human capacity for violence is blatantly obvious and I'm quite astonished that someone could be so naive that they're suprised that we're all capable of violent acts.John Kingston, Hertford, UK | |
| The article is correct in its assertion that we are all capable of violence, The worst potential for violence, however, occurs when a charismatic leader grooms a country and its citizens to use violence against a group or for the purpose of territorial expansion. Recent examples of this are Hitler and General Tojo. Joe Roberts, psychologist, Jackson USA | |
| From studying the diaries of those who perpetrated some of the most brutal and personally involved killings in the Holocaust, the one thing that has stuck with me is how shockingly normal most of those who took part in the killings were - and how eager many participants were. It wasn't just desensitised and committed Nazis, but people you would consider everyday workers who personally killed others in cold blood. One particular incident where railway workers took part in a mass execution of Jews in Poland because they were bored stands out. When you read their accounts of what took place, there is no place for remorse, but instead a giddy excitement untinged by ideology. So much for clear, rational and objective thought ruling human behaviour...Jonny McQuitty, Oxford | |
| Have to think about this one for a while. Would like to think it is reversed and that we are mostly all benevolent people who under the worst circumstances can become violent. Seems that my thinking is not along the lines of this article. We have all had experiences where people we know do bad things that we never thought them capable of. So this lends credence to what is said here. But I am still not totally convinced.Janet, New Athens, IL USA | |
