Genetic Explanations

Why Do Men Commit most of the Crimes?

Men are responsible for 86% of all indictable crimes in England and Wales, 88% of crimes against the person, 90% of murders, and 98% of sexual offences (all for the year 2012).

Testosterone is one of the factors but it is just one of the chemical messengers that make men more risk taking and aggressive.  The real question is why did men evolve to be more risk taking and aggressive in the first place?

There is an (incorrect) assumption that the behaviour and insecurities of men and women is received solely via “socialisation” i.e. an interaction with their environment.  For example a male preoccupation with aggression and risk taking is “caused” by being exposed to other male role models.  This incorrect assumption is based on flawed and discredited social “science” research that fails to correct for genetics.

1. We are a disposable container that has evolved to ensure genes get moved forward in time.  We die.  They don’t.  Any behaviour conferred by the genes on a species, which increases the likelihood of having more offspring, will ensure more of those genes are passed to the next generation.

2. Evolution takes a long time.  One tick of the evolutionary clock takes about 250,000 years.  i.e. we are virtually identical to our ancestors from 50,000 years ago.

Our male and female ancestors have had very different evolutionary pressure over the previous millions of years.

Human females have a pathetic ability to reproduce, having no more than a dozen pregnancies in their lifetime. Each pregnancy is life threatening and she will generally only produce offspring one at a time. Their fertility declines sharply at 35 and falls off a cliff at 40.  Human children are unusually vulnerable in infancy and take many years to reach maturity.  Women therefore engage in a long, energy sapping and life threatening investment in their children to ensure these (few) offspring reach childbearing age.  She must choose her mate with great care to ensure her offspring receive beneficial genes from the father, which in turn maximises the chance of her own genes prospering in the next generation.  It also means she must carefully and selflessly look after the few offspring she manages to produce.  She (i.e. her genes) has no other choice.  So she evolved to be nurturing.

Human males produce 250,000 sperm every second and their number of offspring is limited only by their opportunity to impregnate willing (or unwilling) females.   They are fertile their whole life.  Two strategies would work to increase the number of their genes in the next generation.  1. Look after their offspring, nurture them and ensure they reach child bearing age  (i.e. copy the only strategy available to women). 2. Spread their sperm as far and wide as possible, have thousands of offspring and hope that some reach childbearing age.  A third alternative is the best.  Do both.  Men invest almost nothing in child rearing so it makes sense for them to take huge risks to have the opportunity to reproduce.

It is also worth pointing out why men are so disposable in evolutionary terms, whilst at the same time being more valuable for getting large numbers of genes in subsequent generations if they are very successful and / or out-survive other men.  A population of 100 women and one man has a good chance of survival.  A population of 100 men and one woman is probably doomed.  If men kill off their competitors (in a good war for example) the population can survive and the surviving men’s genes will massively prosper.  If women are killed off their genes won’t prosper due to their very limited ability to reproduce.   Evolution of genes explains why men will be more risk-taking, aggressive and competitive.  Evolution of genes explains why women are dramatically less aggressive.  It’s not in her genes’ interests if the whole population dies out. This also explains why men and women are more likely to put men in harms way and feel more protective towards women (reference: Moral Chivalry).

Women will choose high social status men (a proxy for him having good genes) to ensure their own genes have a good chance of survival in future generations.  To prove high social status takes a bit longer so women tend to go for successful, older men (4 years older in the UK on average).

Men are programmed to advertise their success and achievements in order to attract a high social status mate.  It is worth taking risks to achieve this status because the genetic rewards can be enormous.  For example about 8% of the men in a large region of Asia have Genghis Khan’s Y chromosome.  He clearly had many willing and unwilling sexual partners but took great risk to achieve this.

Men will choose younghealthy, fertile (“attractive”) women because their chosen mate primarily needs to be fit to survive 9 months of pregnancy and the years of childcare that follows. Men have evolved to visually select a mate on this basis.  Women have evolved for millions of years with this pressure.  Women are therefore programmed to try to look young and attractive in order to find a suitable mate. Much of this behaviour is hard wired, as is our sexuality and our urge to have sex with attractive members of the opposite sex.

I’m describing the is not the ought of human behaviour, and nothing here should make us believe we can predict the behaviour of individual men and women.  But please remember evolution is about survival of our genes and does not care one jot about human happiness, fairness or equality.

But to put the male of our species in context here are two relevant facts:
1. Men commit most of the crimes.
2. Few men commit crimes.

Actually we men evolved into a social, altruistic species, with a few violent exceptions.

Also whilst men commit most of the crimes, they are also its main victims:

Men are the main victims of violence and violent death

Men are the main victims of violence and violent death

Many women in the media seem to feel that men don’t know what it’s like to be a victim.  This is something from which women suffer at the mercy of men.  Intuitively we believe this.  We feel protective towards women.  I have two teenage children and worry much more for my daughter when she goes out at night.

However it is my son who is immensely more at risk from an early, violent death.

In the UK men are the victims of 62% of violent crime.  They are also much more likely to die early and violently though accident and trauma. They account for 95% of work related deaths, 92% of motorcycle deaths and have three times the overall road traffic mortality rate as women.  Men account for 75% of suicides and are 68% of all murder victims.

And just to remind ourselves that as a society we are happy to put our young men in harm’s way, the statistics for UK military deaths in Iraq and Afghanistan to May 2012 reports 582 male deaths and 8 female.

All the statistics seem to indicate that the world is a much more dangerous place for men than for women.

They have different and more fatal dangers than those that affect women.  However they are dangers nevertheless.

Men very much know what it’s like to be a victim.

Accidental and Violent Deaths:

Men are considerably more likely than women to have an accident or to die at work. Almost four out of every five (79.5 %) serious accidents at work and nineteen out of every twenty (94.9 %) fatal accidents at work in the EU-27 in 2009 involved men.

(Ref: Health and safety at work statistics)

There is also a significant and notable disparity between the deaths caused by road traffic accidents between men and women, with men being over three times as likely to die from a road accident. 

(Ref: RAC Foundation 2009)

Obviously men take many more casualties in war than women because we are more prepared to put them in harm’s way.  The UK fatalities in Afghanistan and Iraq to May 2012 were 582 men and 8 women.

(Ref: UK Fatalities in Afghanistan and Iraq)

Violent Crime:

Men are more often the victim of violent crime than women: “The CSEW (Crime Survey of England and Wales), which measures the experiences of a representative sample of the population resident in households, provides a good measure of the volume of violent crime offences. It shows 2.1 million offences occurring, based on the 2011/12 survey, mostly against men (62%), mostly not reported to the police (56%), and with a relatively high proportion being repeat victimisations (24%).”

This is statistics from the Crime Survey of England and Wales is based on a survey of peoples’ experience of crime and includes crimes which were not reported to the police.

(Ref:  Office of National Statistics  page 3 and 6)

Suicide:

There were 4,552 male suicides in 2011 (a rate of 18.2 suicides per 100,000 population) and 1,493 female suicides (5.6 per 100,000 population).  i.e. 75% of all suicides are male.

(Ref: Suicides in the United Kingdom, 2011)

Murder:

In the UK 2011/12:  367 murder victims were male and 172 were female. This means that more than two-thirds of homicide victims (68%) were male.

In 2010/11, 435 homicide victims were male and 201 were female.
