James Fallon: The Psychopath Inside Q&A

Professor James Fallon has written an exciting new book combining his background in neuroscience with his personal experience having many characteristics (and the brain scan) of a psychopath. THE PSYCHOPATH INSIDE: A Neuroscientist’s Personal Journey into the Dark Side of the Brain (Kindle version here) is part memoir and part scientific review of both the recent genetic and neuroscience research that has been done on psychopaths.

As a special offer to this blog's audience, Dr. Fallon has graciously offered to answer some of your questions. If you have a question for Dr. Fallon, please post it in the comments addressed to "Dr. Fallon:". I will collect your questions (or a representative sample) and send them to him. When I receive his answers, I will post them in a future blog post.

Here is an except from his book:

I was thinking about putting something up about the book and then asking my readers and twitter followers if they had any questions in particular that they would like to ask him. I could select a representative sample, if he would be willing to give his thoughts? 

One October day in 2005, as the last vestiges of an Indian summer moved across Southern California, I was inputting some last-minute changes into a paper I was planning to submit to the Ohio State Journal of Criminal Law. I had titled it “Neuroanatomical Background to Understanding the Brain of a Young Psychopath” and based it on a long series of analyses I had performed, on and off for a decade, of individual brain scans of psychopathic murderers. These are some of the baddest dudes you can imagine—they’d done some heinous things over the years, things that would make you cringe if I didn’t have to adhere to confidentiality agreements and could tell you about them. 

But their pasts weren’t the only things that separated them from the rest of us. As a neuroscientist well into the fourth decade of my career, I’d looked at a lot of brain scans over the years, and these had been different. The brains belonging to these killers shared a rare and alarming pattern of low brain function in certain parts of the frontal and temporal lobes—areas commonly associated with self-control and empathy. This makes sense for those with a history of inhuman violence, since the reduction of activity in these regions suggests a lack of a normal sense of moral reasoning and of the ability to inhibit their impulses. I explained this pattern in my paper, submitted it for publication, and turned my attention to the next project. 

At the same time I’d been studying the murderers’ scans, my lab had been conducting a separate study exploring which genes, if any, are linked to Alzheimer’s disease. As part of our research, my colleagues and I had run genetic tests and taken brain scans of several Alzheimer’s patients as well as several members of my family, who were serving as the normal, control group. 

On this same October day, I sat down to analyze my family’s scans and noticed that the last scan in the pile was strikingly odd. In fact it looked exactly like the most abnormal of the scans I had just been writing about, suggesting that the poor individual it belonged to was a psychopath— or at least shared an uncomfortable amount of traits with one. Not suspicious of any of my family members, I naturally assumed that their scans had somehow been mixed with the other pile on the table. I generally have a lot of research going on at one time, and even though I try to keep my work organized it was entirely possible for things to get mixed up. Unfortunately, since we were trying to keep the scans anonymous, we’d coded them to hide the names of the individuals they belonged to. To be sure I hadn’t mixed anything up, I asked our lab technician to break the blind code. 

When I found out who the scan belonged to, I had to believe there was a mistake. In a fit of pique, I asked the technician to check the scanner and all the notes from the other imaging and database technicians. 

But there had been no mistake. 

The scan was mine.

Almost sociopath (part 2)

From a reader (cont.)

The main issue in my hesitation at self-diagnosis is this...I know enough people similar to me - in and out of my own family - that also fit these parameters to a certain extent to still be unsure.

My mother seemed to have had similar experiences in her past.  She is a control freak with those around her (though especially with me) and has to be right (Dr Phil asks "would you rather be right or happy?", to her being right IS being happy).  She is very charming, people seem to like her a great deal, but when they prove to be less-than in some way to her she'll grow a tad nasty with them...this includes me with whom she's grown overly aggressive to the point of abusive - emotionally and mentally if not, once or twice, physically.

My grandmother is the same...though seems more borderline/narcissistic in personality and her behavior may also be due to other medical issues.  My grandfather was known to have many behavioral problems as a boy/teen and was, even by his own confession looking back, abusive to his children ("it was the way it was back then"), but did well in the navy and, after the birth of his children, did not have criminal issues at all to my knowledge.  One aunt was known to be promiscuous and switch her entire personality with each mate (I always imagined borderline more than anything) while the other settled happily into a marriage in which both her and husband live beyond their means without much concern for the future consequences - :cough: IRS audit :cough:.  My uncle is the most clearly the "typical sociopath" with a string of moves, jobs, and even (easily debunk-able) lies in his wake - he is also, though, the lowest-functioning person in the family so that could be why I'm most aware of his "typical" sociopathic behavior.

Some of my friends often seem to have the same viewpoint and will make similar-type jokes as me - including those others have called "wrong", "mean", etc - and will both laugh at and repeat my own.  They seem amused by the same things, to wanna do the same things, and believe the same general things as I do...but I wonder if this one isn't a bit of a chicken and the egg situation.  Are they conforming to me or am I conforming to them?

Or am I seeing a likeness that's not truly there for some self-denial/self-comforting (they're similar, thus like me, thus I'm "normal") reason??  (Other family members, to my knowledge, have not done any sort of cruelties to those around/close to them and they emote more frequently with more genuineness, it seems.)     ....OR are they all also truly like me?

And, if both family and friends are truly like me, then am I not a sociopath at all?  Or, maybe, am I an "almost" or "borderline" sociopath (most self-tests online came back as this or as "high-functioning")?  OR have I been surrounded by enough my own kind for long enough that I never realized what, exactly, my "kind" was until your blog, which resonates so thoroughly with me I swear I could've written some of the posts myself?

Any help you can offer would be much appreciated, any thing you need answered in order to help me I'll answer (outside the details of true name, etc, of course).  If you wish to put this up on the blog that is also fine...perhaps others are in a similar situation as mine and need the help.

Sincerely

"Skye"

PS: Please note I'm a tad late to the game on this - I'm 30 - but was always a late bloomer in personality, if I was to move to the next stage at all.  (I only truly realized the gender of my mate is irrelevant to me a few years ago, I still live with my mother due to crap financial issues - I'm working to rectify this one now - and never moved beyond the "I shouldn't do that because, if caught, I'll get in trouble"...it is seriously the only thing that keeps me in line, if I think I can get away with something I will absolutely give it a go.)

Nature vs. nurture

This New York Times article states the obvious -- bad parents can't take all the credit for good children and good parents can't take all the blame for bad children. Interestingly, it goes out of its way to say that bad behavior does not necessarily equal sociopathy:
“I don’t know what I’ve done wrong,” the patient told me.
She was an intelligent and articulate woman in her early 40s who came to see me for depression and anxiety. In discussing the stresses she faced, it was clear that her teenage son had been front and center for many years.
When he was growing up, she explained, he fought frequently with other children, had few close friends, and had a reputation for being mean. She always hoped he would change, but now that he was almost 17, she had a sinking feeling.
I asked her what she meant by mean. “I hate to admit it, but he is unkind and unsympathetic to people,” she said, as I recall. He was rude and defiant at home, and often verbally abusive to family members.
Along the way, she had him evaluated by many child psychiatrists, with several extensive neuropsychological tests. The results were always the same: he tested in the intellectually superior range, with no evidence of any learning disability or mental illness. Naturally, she wondered if she and her husband were somehow remiss as parents.
Here, it seems, they did not fare as well as their son under psychiatric scrutiny. One therapist noted that they were not entirely consistent around their son, especially when it came to discipline; she was generally more permissive than her husband. Another therapist suggested that the father was not around enough and hinted that he was not a strong role model for his son.
But there was one small problem with these explanations: this supposedly suboptimal couple had managed to raise two other well-adjusted and perfectly nice boys. How could they have pulled that off if they were such bad parents?
To be sure, they had a fundamentally different relationship with their difficult child. My patient would be the first to admit that she was often angry with him, something she rarely experienced with his brothers.
But that left open a fundamental question: If the young man did not suffer from any demonstrable psychiatric disorder, just what was his problem?
My answer may sound heretical, coming from a psychiatrist. After all, our bent is to see misbehavior as psychopathology that needs treatment; there is no such thing as a bad person, just a sick one.
But maybe this young man was just not a nice person.
For years, mental health professionals were trained to see children as mere products of their environment who were intrinsically good until influenced otherwise; where there is chronic bad behavior, there must be a bad parent behind it.
But while I do not mean to let bad parents off the hook — sadly, there are all too many of them, from malignant to merely apathetic — the fact remains that perfectly decent parents can produce toxic children.
When I say “toxic,” I don’t mean psychopathic. . . .
I often tell readers that not every asshole ex of theirs is a sociopath, and the same applies for misbehaving children. In this situation, though, I actually think it is foolish to discount the potential role of sociopathy. There is a strong genetic but weak environmental link to sociopathy, which is consistent with having two normal sons and one sociopathic one. Furthermore, although inconsistent discipline may not be enough to cause anyone to become a sociopath, it could trigger sociopathy in someone who was genetically predisposed to it, as sociopath children are particularly sensitive to incentive structures and perceived fairness (i.e. consistency and reciprocity). I obviously don't know the full story, but just based on the article, the description fits sociopathy, at least for this kid.

After spending time with my family recently, I am more convinced that nurture had a significant role to play in my development into a sociopath. When people ask me whether I had a bad childhood, I tell them that it was actually relatively unremarkable, however I can see how the antisocial behaviors and mental posturing that now define me were incentivized when I was growing up -- how my independent emotional world was stifled and how understanding and respect for the emotional world of others died away. Still I don't think I was "made" into a sociopath, nor was I born one. I feel like I was born with that predisposition, that I made a relatively conscious decision to rely on those skills instead of developing others, and that the decision was made in direct response to my environment and how I could best survive and even thrive in that environment. It's a bit similar to this author's description of her own survivalist adaptations:
If you’ve read much about writers, you know that many of us grew up with an alcoholic parent or in some otherwise dysfunctional home. Me, too. Kids who are raised in households where feelings of safety and predictability are up for grabs might be more likely to turn into storytellers. We spend a lot of emotional energy trying to guess what might happen next, and mentally drawing up different contingency plans. It puts us in the “what if” habit early.
Genetics are important for sociopathy, but environment plays a crucial role as well. Although the NY Times article notes that "[f]or better or worse, parents have limited power to influence their children," such that they should be reluctant "to take all the blame — or credit — for everything that their children become," unfortunately (or luckily?) they can still take quite a bit of blame (or credit) for sociopathic children, particularly with new "studies suggesting that such antisocial behavior can be modified with parental coaching." Knowledge is power.

Psychopath: the documentary


This hour long documentary is probably worth watching, particularly for people who are just learning about sociopathy. For the sociopaths, most of it will seem a little over the top, but for some reason that passes as science and journalism when it comes to the dreaded sociopath.

Interesting moments:

27:42 What sociopaths are doing/thinking when they are talking to you.

31:14 Nature vs. nurture -- environment alone isn't enough to create a sociopath, otherwise we'd see more sociopaths in war torn areas, also "intervening" with child sociopaths.

34:40 Biological basis for the condition.

42:40 Treatment.

45:05 Mandatory brain chips and/or "surgical intervention" for sociopaths.

Microchips in the brain is by far the scariest idea I have even heard of to "deal" with the "psychopath problem," and I have heard of a lot of creative ones involving islands, internment camps, or specialized soldiers. My favorite comment:

“we will replace ‘dysfunctional’ brain mechanisms with microchips” what the…!?!?!?!!! no you wont, i’ll quite happily be labelled as psychotic for violently opposing such an idea! ultimate mind control! ill be thankful for some violent psychopaths when the powers that be try that one!!!! The moral authority of these guys is terrifying to say the least it absolves them as ‘normal’ people, my definition of psychopath would include anyone who thinks mind control chips are an acceptable course of action! microchip control for difficult people who dont fit into a society that worships money and rewards the ‘industrial psychopaths’ with untold riches. i wonder if we are all a little bit psychotic and these therapists are the abnormal ones in trying to standardise emotional response to life events- prescribing that any given situation has a ‘proper’ emotionally standard response? the guy who describes the psychopaths abnormality as reading someone else’s faces and tailoring what they say in response- like this is some sort of weird anomaly. pathologically frightened control freaks are what the therapists come across as by their own diagnostic criteria, desperately seeking to reign in the personalities they cannot understand. i’ve watched some scary documentaries by alex jones et al about social control but this one is far more frightening in its implications. eugenics is alive and well, cull the abnormal, praise be to the sheepthinkers.

Can we eliminate evil?

A reader suggested this Morgan Freeman narrated special "Through the Wormhole: Can We Eliminate Evil?" Not surprisingly, it features sociopaths and studies on the brain that give interesting insight to how we decide what to do and what constitutes evil.

The first clip is about empathy, and illustrates well the recent study that found that sociopaths feel empathy when directed to put themselves in the shoes of others.




If you have the genetics of a killer and the brain anatomy of a killer, are you destined to become a killer? James Fallon.




And finally this was an illustration of this experiment regarding the moral lives of babies.

Free will = not what you think it is

This is an interesting lecture from philosopher and neuroscientist Sam Harris about how the common conception of free will is not scientifically supported. Specifically he debunks two assumptions on the popular conception of free will: (1) we are each free to think and act differently than we did in the past ("you became a police man, but you could have become a firefighter") and (2) we are the conscious source of our thoughts and actions, i.e. we feel like we want to do something so we do that thing. The problem with these assumptions is that "Everything that could possibly constitute your will is either the product of a long chain of prior causes, so you're not responsible for them, or it's the product of randomness, and you're not responsible for that, obviously, or it's some combination of the two."


He has an interesting analogy at the beginning about a man sleeping in a park and getting his face bitten off by an alligator versus a man with the axe. The result is the same, but people hate the man and not the crocodile because wWhat else is a crocodile going to do, coming upon you napping in the park" whereas a man is allegedly in control of his actions.

Another interesting assertion: "Most people imagine that a belief in free will is necessary for morality. . . . The difference between happiness and suffering exists without free will." Still, there are a lot of interesting implications for morality. At 46:00 he talks about how we can make reasonable distinctions between premeditated and impulsive crime given that free will doesn't exist. punishment, morality, etc.

"In specific cases we have already changed our view of evil. Whenever we see the cause of someone's behavior, when we see for instance that a murderer had a brain tumor . . . so as to explain his violent impulses, that person suddenly becomes a victim of biology. Our moral intuitions shift utterly. Now I'm arguing that a brain tumor is just a special case of physical events giving rise to thoughts and actions. If we fully understood the neurophysiology of any murderer's brain, it would be as exculpatory as finding a tumor in it. If we could see how the wrong genes were being relentlessly transcribed, if we could see how his early life experience had sculpted the micro structure in his brain in just such a way as to give rise to violent impulses, the whole conception of placing blame on him would erode."

Common genetic risk basis for psychiatric disorders

The NY Times reports the findings of a new study that links the same genetic glitch to schizophrenia, bipolar disorder, autism, major depression and attention deficit hyperactivity disorder. And sociopathy? I see autism and ADHD on there, both of which I think are related to sociopathy.


Their study, published online Wednesday in the Lancet, was based on an examination of genetic data from more than 60,000 people worldwide. Its authors say it is the largest genetic study yet of psychiatric disorders. The findings strengthen an emerging view of mental illness that aims to make diagnoses based on the genetic aberrations underlying diseases instead of on the disease symptoms.

Two of the aberrations discovered in the new study were in genes used in a major signaling system in the brain, giving clues to processes that might go awry and suggestions of how to treat the diseases.

“What we identified here is probably just the tip of an iceberg,” said Dr. Jordan Smoller, lead author of the paper and a professor of psychiatry at Harvard Medical School and Massachusetts General Hospital. “As these studies grow we expect to find additional genes that might overlap.”
***
Researchers had already seen some clues of overlapping genetic effects in identical twins. One twin might have schizophrenia while the other had bipolar disorder. About six years ago, around the time the new study began, researchers had examined the genes of a few rare families in which psychiatric disorders seemed especially prevalent. They found a few unusual disruptions of chromosomes that were linked to psychiatric illnesses. But what surprised them was that while one person with the aberration might get one disorder, a relative with the same mutation got a different one.

Jonathan Sebat, chief of the Beyster Center for Molecular Genomics of Neuropsychiatric Diseases at the University of California, San Diego, and one of the discoverers of this effect, said that work on these rare genetic aberrations had opened his eyes. “Two different diagnoses can have the same genetic risk factor,” he said. 

In fact, the new paper reports, distinguishing psychiatric diseases by their symptoms has long been difficult. Autism, for example, was once called childhood schizophrenia. It was not until the 1970s that autism was distinguished as a separate disorder.

I thought this was very interesting, especially the one twin schizophrenic and the other bipolar. I get a lot of emails and see a lot of comments where people mention that there is someone in their family who is a narcissist or BPD or bipolar. It could be that being exposed to these people in an intimate, familial setting could be the environment that is triggering otherwise unrelated genes in sociopaths, etc.? Or maybe we all share more in common genetically than we had previously considered. Right aspies?

Of course the predicament here is that if we killed sociopaths or put them on an island, that really wouldn't weed out the gene, would it? Sterilize sociopaths? Same argument would apply to anyone who shared the genetic risk factor, maybe bipolar, autistics, etc.? Genocide targeting sociopaths may have gotten just a little bit more complicated.

What exactly is psychopathy?

A reader sent this interesting article from one of our favorite researchers, Jennifer Skeem, whose previous attack on the PCL-R caused Robert Hare to take her to court and delay the publication before it was eventually released. The article is sort of an interesting primer on psychopathy and summary of the most recent research. She has her own ideas about the correct delineation of psychopathy that seems reasonable. First she discusses why there are so many ideas about what exactly sociopathy is:

As we will discuss, many of the controversies surrounding psychopathy stem from fundamental disagreements about its basic definition, or operationalization. The scope of phenomena encompassed by the term psychopathy has varied dramatically over time, from virtually all forms of mental disorder (psychopathy as “diseased mind”) to a distinctive disorder characterized by lack of anxiety; guiltlessness; charm; superficial social adeptness; dishonesty; and reckless, uninhibited behavior (Blackburn, 1998). Even contemporary conceptualizations of psychopathy contain puzzling contradictions. Psychopaths are often described as hostile, aggressive, and at times revenge driven (N. S. Gray, MacCulloch, Smith, Morris, & Snowden, 2003), yet they are also characterized as experiencing only superficial emotions (Karpman, 1961; McCord & McCord, 1964). They are impulsive and reckless, yet apparently capable of elaborate scheming and masterful manipulation (Hare, 1993). They can rise to high levels of achievement or status in society, attaining success in business and public life, yet present as criminals whose behavior is so poorly thought out and lacking in regard even for self-interest that they occupy bottom rungs of the social ladder

Given these contrasting depictions, it is scant wonder that some experts have concluded that the concept of psychopathy, as commonly understood, is disturbingly problematic: a “mythical entity” and “a moral judgment masquerading as a clinical diagnosis” (Blackburn, 1988, p. 511), “almost synonymous with ‘bad’” (Gunn, 1998, p. 34), “used by the media [to convey] an impression of danger, and implacable evil” (Lykken, 2006, p. 11). In the words of William and Joan McCord (McCord & McCord, 1964), two influential figures in the historic literature on psychopathy, “the proliferation of definitions, the tendency to expand the concept to include all deviant behavior, the discrepancies in judgment between different observers——these pitfalls in the history of the concept—— are enough to make a systematic diagnostician weep” (p. 56).

She then (optimistically) asserts that all is not lost, that sociopathy is a thing and we can figure out what that thing is through careful parsing of the literature and empirical evidence. First she dispels some myths:

  • Psychopathy is synonymous with violence: "However, psychopathy can and does occur in the absence of official criminal convictions, and many psychopathic individuals have no histories of violence."
  • Psychopathy is synonymous with psychosis: "In contrast with psychotic patients, psychopathic individuals are generally rational, free of delusions, and well oriented to their surroundings"
  • Psychopathy is synonymous with antisocial personality disorder (ASPD): "The difference arises largely because measures of psychopathy include personality traits inferable from behavior, whereas measures of ASPD more exclusively emphasize antisocial, criminal, and (to a lesser extent) violent behavior."
  • Psychopathic individuals are born, not made: "Contemporary understanding of the pervasive interplay of genetic and environmental influences in determining behavioral outcomes of various kinds argues against the likelihood that any psychiatric condition, including psychopathy, is entirely 'born' or 'made.'"
  • Psychopathy is inalterable: "some recent empirical work has emerged to suggest that personality traits in general, and psychopathic traits more specifically, undergo change across major developmental transitions"

The article is quite long. I will probably keep going back to it over the next month or so and perhaps sharing things that I learn here.

Socios: all in the family


This is one of my favorite songs. I love the lyrics: "One child grows up to be somebody that just loves to learn and another child grows up to be somebody you'd just love to burn. Mom loves the both of them, you see it's in the blood. Both kids are good to mom -- blood's thicker than mud." Of course when I first heard the song I thought I heard "Somebody that just loves to burn," which was obviously more applicable, but the rest is true -- my family loves me just as much as my empath siblings. But with the holidays upon us, I have been thinking about socio family members. Some think that as many as 1 in 25 people are sociopaths, and if that's the case you'd imagine that even more people have a sociopath in the family. Or maybe you turn out to be the sociopath in the family, like the man in this article:
Jim Fallon recently made a disquieting discovery: A member of his family has some of the biological traits of a psychopathic killer.
* * *
Three years ago, as part of a personal project to assess his family's risk of developing Alzheimer's disease, Dr. Fallon collected brain scans and DNA samples from himself and seven relatives. At a barbecue soon thereafter, Dr. Fallon's mother casually mentioned something he had been unaware of: His late father's lineage was drenched in blood.

An early ancestor, Thomas Cornell, was hanged in 1673 for murdering his mother. That was one of the first recorded acts of matricide in the Colonies. Seven other possible killers later emerged in the family tree. The most notorious was distant cousin Lizzie Borden of Fall River, Mass. In 1892, she was accused and then controversially acquitted of killing her father and stepmother with an ax.

As a lark intended to enliven family get-togethers, Dr. Fallon decided to analyze the data from the Alzheimer's project to see whether anyone in his family matched the profiles of killers he had studied. His initial subjects included himself, his three brothers, his wife, and the couple's two daughters and son.
* * *
To his surprise, Dr. Fallon found that the analysis of his own brain showed he had inherited certain high-risk forms of MAOA and other various aggression-and violence-related genes.

"I'm the one who looks most like a serial killer," he says. "It's disturbing."
* * *
"I'm still in balance, but I seem to have low emotional engagement," says Dr. Fallon, noting that the brains of many cold-blooded murderers reveal a similar picture.

Dr. Fallon thinks that one vital factor may have prevented him from becoming a killer. "I had a charmed childhood," he says. "But if I'd been mistreated as a child, who knows what might have happened?"
The moral of this story to me is be careful how much you preach about genetic testing and forced imprisonment of sociopaths because you may turn out to be one of us.

Lighter sentencing for genetic predispositions

This NY Times article discusses new experimental evidence that suggests that when judges (not juries) sentence criminals for whom there is evidence of genetic predisposition to violence and crime (in this experiment, psychopaths), they give lighter sentences than they otherwise would:

The new experiment focused on sentencing by judges, not jury verdicts. It found that neurobiological evidence reduced judges’ sentences by an average of about 7 percent for a fictional defendant convicted of battery and identified as a psychopath.


In the study, three researchers at the University of Utah tracked down 181 state judges from 19 states who agreed to read a fictional case file and assign a sentence to an offender, “Jonathan Donahue,” convicted of beating a restaurant manager senseless with the butt of a gun. All of the judges learned in their files that Mr. Donahue had been identified as a psychopath based on a standard interview — that is, he had a history of aggressive acts without showing empathy.

The case files distributed to the judges were identical, except that half included testimony from a scientist described as “a neurobiologist and renowned expert on the causes of psychopathy,” who said that the defendant had inherited a gene linked to violent, aggressive behavior. This testimony described how the gene variant altered the development of brain areas that generate and manage emotion.
***
The judges who read this testimony gave Mr. Donahue sentences that ranged from one to 41 years in prison, a number that varied with state guidelines. But the average was 13 years — a full year less than the average sentence issued by the judges who had not seen the testimony about genetics and the brain.
***
“But then those who read about the biological mechanism subtracted a year, as if to say, ‘This guy is really dangerous and scary, and we should treat him as such, but the biological evidence suggests that we can’t hold him as responsible for the behavior,’ ” said James Tabery, an assistant professor of philosophy at Utah.
***
This mixed result — added punishment for the defendant’s being identified as a psychopath, tempered by empathy for his having a possible genetic predisposition — provides a good illustration of what legal researchers call the double-edged sword of biobehavioral evidence. On one hand, a biological predisposition suggests that a person is likely to be dangerous in the future and should get a longer sentence; on the other, it implies a lower threshold of responsibility. The evidence could cut either way, depending on the judge.

Almost a psychopath

From illustrious reader Daniel Birdick, regarding the book Almost a Psychopath: Do I (or does someone you know) have a problem with manipulation or lack of empathy?, in which people are apparently psychopathic without necessarily rising to the level of diagnosis:

I skimmed through the the Almost a Psychopath book. They adhere to the Hare definition of psychopathy and then label the "almost psychopath" as someone who behaves like a diagnosed psychopath, only less so. Very scientifically precise, no?~
This spectrum issue reminds me of the 2nd James Fallon video from one of your recent posts. Here this guy is, with the DNA and the brain of a serial killer, yet instead of becoming a murderer he instead becomes a neuroscientist. He is clueless about the impact of his own behavior on others up until the point when he sees the results of the brain scans, although his family is completely unsurprised by his discoveries. So, by virtue of his utter lack of caring and his genetic and neurological makeup, can we call him an almost psychopath? Or does the absence of antisocial or criminal behavior (relative to diagnosed psychopaths) indicate that he is not at psychopath at all, in any way that matters? Some, like good old Dr. Robert, base their notions of psychopathy entirely on what does or does not happen on the inside. The Hare checklist on the other hand is behaviorally based, with a few exceptions. I think the checklist assumes, to paraphrase the ultimate paragon of passivity, that you shall know a tree by its fruits. What you experience on the inside only matters when it expresses itself on the outside. I am inclined to agree. What you do matters more than what you don't feel. So what if you feel callous and unemotional on the inside. What matters is how you actually treat people. Right? Why then all the blather about empathy and emotional responses to social faux pas, like guilt and shame? Is it the whole authenticity thing? I find that to be another red herring. What self are we being authentic about? Where is this ghost in the machine and why won't it show up on a PET scan? Is it really "virtuous", whatever the hell that means, to be honest and admit that you don't give a flying fuck about whatever sob story some clueless twat wants to lay on you, or is it in fact more moral to pretend to care by aping the right facial expressions and body language?
Went on a bit of a rant there. Anyway...

Nurture trumping nature

I have posted before about James Fallon, neuroscientist, University of California, Irvine, professor, psychopath expert, and successful psychopath (?) before.  I thought this video was worth posting as well because it targets more the personal experience of what his family thinks about who he is and his childhood was instrumental in Jim not developing into a killer, despite his brain and genetic predispositions.




6:55: His mother tells him about how Lizzie Borden is a cousin of his.  On one line of his family there were at least 16 murderers.

7:54: He decides to check the brain scans and DNA of his family members for the brain signatures and genes linked to psychopathy.  He discovers everyone is normal except for him, who has the brain scan signature of a killer and all of the genetic markers predisposing to impulsivity, violence, etc.

10:05: Reaction from his family "I knew there was always something off.  It makes more sense now."  "Everything that you would want in a serial killer he has in a fundamental way."  "It was surprising but it wasn't surprising."  "He's always had a standoffish part to him."

11:00: Jim is honest with himself "I have characteristics or traits, some of which are . . . psychopathic." he gives the example of how he could blow off an aunt's funeral.  "I know something's wrong, but I still don't care."

11:40: Why wasn't he a killer?  "Whether genes are triggered or not will depend on what happens in your childhood."

12:28: "It turns out that I had a unbelievably wonderful childhood."

I think this is an interesting and accurate portrayal of what a high functioning psychopath might look like.  I think people expect to see very obvious differences, but frequently they're not obvious or they're not really visible.  It's like this response from Jennifer Kahn, author of that NY Times Magazine article on psychopathic children, when asked about whether the child's behavior was more or less extreme than she expected:

I think I expected Michael to be more immediately extreme. When I arrived, he was on his good behavior, but he did get extreme later in the night. Something that Waschbusch said he struggles with is that it is hard to define what is prepsychopathic behavior and what is behavior caused by a different kind of problem — it does tend to cross different diagnoses. It wasn’t the screaming or fits or slamming the toilet seat that struck me; it was the calculated coldness and the flip between emotional states. But I had expected it to be more obvious. When I entered the house, of course, I was thinking of adult psychopaths who have led criminal lives for decades, which is normally how they come to our attention. I was maybe expecting a child version of that, but of course that’s kind of ridiculous. Even among adult psychopaths, that would be a small minority.

How sociopaths are made?

I've been reading Social Intelligence by Daniel Goleman and thinking about how and why I became a high functioning sociopath. Psychologists and scientists believe sociopthy is some combination of genes and environment, which makes sense, particularly in light of recent research suggesting that not only do genes matter, but that the body's varying expression of the genes appears in response to environmental or other factors. As Dr. Goleman says:
If a gene never expresses the proteins that could direct the body's functioning in a given way, then we may as well not possess that gene at all.
If there were some triggering event or environmental force that triggered my sociopathy, I think it was just as likely something that happened to me as a baby than something within my conscious memory. For instance, when I was an infant I had a particularly bad case of colic, a poorly understood condition affecting infants whose main symptom is "frequent, inconsolable crying." According to my parents, I cried incessantly, and according to my medical records I had to go to the doctor for a ruptured navel due to excessive crying. I'm sure my parents did as well as they could, but it no doubt must have been difficult to tolerate such a child, much less nurture it.

Dr. Goleman says that although the brain doesn't reach maturity until 20, the biggest growth spurt is in the first 24 months of life. He also cites a study regarding the importance of the very beginning of a mammal's existence in brain programming:
[A]t least for mice, a vital way that parenting can change the very chemistry of a youngster's genes. [A] singular window in development [is] the first twelve hours after a rodent's birth--during which a crucial methyl process occurs. How much a mother rat licks and grooms her pups during this window actually determines how brain chemicals that respond to stress will be made in that pup's brain for the rest of its life.

The more nurturing the mother, the more quick-witted, confident, and fearless the pup will become; the less nurturing she is, the slower to learn and more overwhelmed by threats the pup will be.

The human equivalents of licking and grooming seem to be empathy, attunement, and touch. If [this research] translates to humans . . . then how our parents treated us has left its genetic imprint over and above the set of DNA they passed down to us. And how we treat our children will, in turn, set levels of activity in their genes. (pp. 152-54)
The book is not all that helpful for sociopaths, and has a low opinion of us generally, so I wouldn't recommend taking the time to read it. But maybe I'll post some other sociopath-specific information I find.
