For the past 18 years, I have studied the brain activity, psychology, and genetics of psychiatric
patients and the brain scans of psychopathic serial killers. A few
months ago, I was approached by a non-profit human rights organization
to create a presentation on the mind of a dictator--an especially
compelling issue in light of recent uprisings against autocrats in the
Middle East and North Africa.
After combing through literature on the
world's worst dictators and combining it with my neuroscience research
and that of others on psychopaths, I presented my theory in May at the Oslo Freedom Forum,
an annual conference produced by the Human Rights Foundation. The
following article is based on my speech, an attempt to look inside the
minds of these elusive and powerful world players.
So, what binds dictators across history and geography? What traits do
they share? To begin with, let's examine the general characteristics of
psychopaths. They are usually charming, charismatic,
and intelligent. They brim with self-confidence and independence, and
exude sexual energy. They are also extremely self-absorbed, masterful
liars, compassionless, often sadistic, and possess a boundless appetite for power. These are just a few of the character traits present in a genuine psychopath.
There
is a dearth of brain-scanning and genetic reports on dictators, but the
distinct psychological traits common to the classic psychopath can be
used as a starting point in studying their behavior. I have analyzed the
traits of many modern-day dictators and have identified commonalities
with classic psychopaths. Libya's Muammar al-Gaddafi, for example, is
paranoid, narcissistic, power-hungry, and vain. Belarus's Alexander
Lukashenko is among the world's most dangerous dictators; he actively
attacks his opposition-a clear sign of malignant psychopathic
megalomania that is almost impossible to satisfy.
Meanwhile, Venezuela's
Hugo Chávez is a freedom-fighter turned dictator, somewhere in the
middle of the scale between normal and psychopath. Though not a
dictator, I would like to have scanned the brain and tested the DNA of
Osama bin Laden. He exhibits many traits typical of classic psychopathic
dictators--grandiosity, charm, vengeance, vanity, and sadism. With his
abrupt maritime burial, we missed a tremendous opportunity to study the
inner workings of an evil mind.
Somewhat
predictably, dictators do not relate in a normal manner to other people
in a person-to-person, empathetic way. They may associate themselves
with "people" as a whole or "people" in a tribal or abstract pan-world
sense (as Hitler may have had with pan-Germanism, or Stalin with
pan-Slavic sentiments), or even with "the world"-anonymous variables
that they exploit at their own discretion. But beyond any generalized
pan-nationalistic "empathy," which they usually exploit at their own discretion, what actually makes a person psychopathic?
Just
behind the eyebrows and deep to the neocortex in the temporal and
frontal lobes, is the extended amygdala. It is a key node in the brain
circuit that mediates "animal instincts" and it contributes to making 2
percent of the world's population psychopaths--and a few of the most
versatile and talented of these become dictators.
In the brain's
lower frontal lobe--the orbital cortex, ventromedial prefrontal cortex,
and anterior cingulate cortex--we find the circuit that is likely to be
damaged in the psychopathic dictator, where aggressive impulses
originating in the amygdala are inhibited and moral and ethical choices
considered through interactions with the orbital and ventromedial
cortex. People with low activity in this area are particularly
predisposed to impulsive
or psychopathic behavior. When we struggle with moral
dilemmas--fighting between the angel and the devil in ourselves--this
part of the brain is activated. However, when the center of the frontal
lobe is malformed or injured, it fails to activate and the amygdala in
the temporal lobe takes over and controls behavior.
The amygdala is a major center for the circuits that regulate fear, rage, and sexual desire, emotional memory,
among other things. This part of the brain center is directly connected
to the ancient survival and appetite center in the septum,
hypothalamus, and brainstem, is dysregulated in some people with
emotional problems. This can occur developmentally during fetal
development and can be affected by both genes (especially those
associated with serotonin and the other monoamine neurotransmitters) and
environment (e.g., maternal stress, drugs
of abuse, severe stress).
Both the frontal lobe and the amygdala
connect with each other, and with the brain's hedonistic hotspot in the
nearby nucleus accumbens and are in a moment-to-moment fight
for control of behavior. Either the morality compass and impulse control
mechanisms of the lower frontal lobe, or the more animal amygdala in us
wins that battle. In some individuals, the amygdala can be so poorly
developed that it creates an extreme pattern of dependency.
So
what satisfies a normal person--such as reading a good book or watching
the sunset--does nothing for someone with an underdeveloped amygdala.
For some people, this means a greater tendency toward drug and alcohol addiction
and severe painful withdrawal that gets progressively worse over time,
leading to malignant dependent behaviors. For sadists, they become
addicted to torture and killing; dictators get high on power, an
insatiable drive that gets progressively worse, or malignant with time.
Contributing
to my own hypothesis on the basis of psychopathic behaviors, I
considered differences in the brains of psychopathic serial
killers. Over the past 15 years, I have examined functional and
structural brain scans of murderers in comparison to normal people as
well as those with schizophrenia, depression,
addictions, and neurodegenerative diseases. Even in blind analyses of
large numbers of such scans, it became obvious that the psychopathic
murderers had a common pattern of functional loss in the orbital and
ventromedial cortex of the frontal lobe, the anterior-medial temporal
lobe especially in the amygdala, and adjacent limbic cortices such as
the anterior cingulated cortex.
However, there are other factors that may need to be present to breed a cold-blooded murderer. The warrior gene,
MAO-A, is one of over a dozen genes that are associated with aggressive
behavior, and may also play a role in the creation of a killer,
although it has yet to be proven that these gene variants actually cause
such behaviors. Some of these aggression related genes such as MAO-A
are transmitted from mother to child through the X chromosome, but it is
more prevalent in men due to the fact that males have only one X
chromosome, thus if they inherit the warrior gene, it will always be
active.
Women have two X chromosomes, but one is turned off by chance (X inactivation)
so more women are likely, in a probabilistic way, to have an inactive
warrior gene. Some of these gene variants such as the promoter for the
serotonin transporter, while though to predispose one to the harmful
long-term effects of early abuse, also enhance positive, loving early
experience that can offset the otherwise negative biological
determinants.
In addition, men are particularly predisposed to a gene
variant for vasopressin, which makes them prone to poor mate or
interpersonal bonding and perhaps more likely to exhibit clan behavior (tribalism). Men are also impacted by genetic variants for the androgen sex
receptor, with one variant or allele favoring magnanimity and the other
fostering selfishness. It is no coincidence that all dictators are men.
When looking at demographics, around 30 percent of Caucasians are found to have the MAO-A (short form) warrior gene. The
rate is similar among Africans, despite the daunting physical
environments, tribal cultures, and that they have higher dictators per
capita than any other continent. The highest level is found in the
Chinese and Polynesian population; 60 percent are equipped with a
warrior gene.
Variants of this gene have differential impacts on
different ethnicities, so a high rate in one ethnicity does not mean
they would tend to be more aggressive, since many genes are involved and
the way these genes interact with other genes (epistasis) varies in
different ethnicities. In general, such complex adaptive behaviors and
traits are impacted by a myriad of gene variants in a way that is only
beginning to be understood. Proving causation between a gene variant and
a behavior is a daunting challenge, especially since any gene might
only contribute 1 or 2 percent to the variance in such behaviors.
To develop into a dictator--in addition to theoretically having a
hefty percentage of the 12 to 15 particularly aggressive gene variants
and a dysfunctional frontal lobe and amygdale--an individual has usually
also been seriously abused in childhood, and/or lost important caretakers, such as biological parents.
Yet such extreme combinations are no guarantee; it is a matter of a
hypothetical probability calculation. A certain degree of some of these
factors are apparent in each and every one of us--as a quantitative trait what matters is the overall gradation.
We often think about dictators in terms of good vs. evil. However, the highly trained soldiers that are sent out to eliminate dictators may have many of the same qualities as their targets. I have worked with defense agencies in the fields of cognition
and extreme small group warfare to discuss how to determine the right
types of people that have the icy, aggressive qualities combined with
the warmth and morality that together make a good soldier who acts
optimally depending on the context of the situation, for example being
in a surprise firefight vs. dealing with the local civilian
population.
Previous gang leaders from L.A. have done particularly well
on one such desirable trait: they seem to have an intuitive sense of
danger and are rarely caught by surprise, and as such are gifted
survivors. In the end, what makes the difference between these soldiers
and dictators, psychopaths, and killers is the balance between their
emotions, drives, instincts, and moral compass in a contextually
appropriate manner.
