Mental illness, autism, and mass murder, or why Joe Scarborough needs to shut up

Today, Joe Scarborough at MSNBC warned viewers not to generalize about the horrific events in Aurora, CO, and then proceeded to opine that the killer in question was "on the autism scale." I'm not exactly sure what "on the autism scale" means, as I've never in all my years of involvement in the autism community come across such a device, but many of us in that community were waiting--nay, expecting--something like this almost from the minute we learned who had committed these murders. Too bad it came from a parent member of that community.

Hey, Joe, you've got a gun in your hand, and it's not like the one that the who-knows-what-his-disorder-is murderer in Aurora used. No. Your weapon is of a more subtle nature, and you wield it from a venue that reaches millions of people who don't know that the ammo you're firing is empty bullshit. But that bullshit ends up smearing the autistic community as violent criminals capable of all manner of psychotic behavior, including the taking of innocent lives and the well-planned rigging of an apartment building with dangerous explosives. And you must understand this on some level, as you have a son who is on the autism spectrum.

Here's the thing, Joe. You're conflating what can be very personal, nonfatal aggression of an overwhelmed autistic person with the wanton and willful and carefully planned destruction of total strangers in a crowded theater. Yes, some autistic people are aggressive, in the moment, in response to a moment, to being overwhelmed and not understood, to being mishandled and misused. That sort of aggression is a very, very different animal from the sort of cold, calculated malevolence that leads a young man to inflict tragedy across a large swath of humanity, total strangers to him, arriving with a measured burst of deadly force before calmly surrendering himself to authorities. You, Joe Scarborough, see that behavior as somehow "on the autism scale." Anyone who has even a mild grasp of autism knows how very far from reality that kind of behavior is for an autistic person. 

So let's talk about violence. 

A look at the violence literature reveals two rough categories of violent brain and genetics: the brain of the impulsively or hostilely violent and the brain of the proactive, or instrumentally violent--the one who carefully plans the violent act, rather than committing it in the heat of the moment. Impulsive violence, thanks to its unpredictability and relative ubiquity, seems to get the bulk of the attention. Proactive violence, which encompasses the planned violence of war, is a different animal altogether. And psychopathic instrumental violence may well be the most terrifying of them all. The two appear to have very different underlying mechanisms and origins, as well:
Biological models of violence have identified distinct neural patterns that characterize each type of violence. For example, the "low-arousal" aggressor more likely to commit instrumental violence is underreactive and responds sluggishly to stressors. In contrast, the "high-arousal" aggressor who is more prone to hostile violence tends to be hypervigiliant and easily frustrated 
In humans, instrumental aggression is roughly analogous to predatory aggression although it is limited to intraspecies behavior....Similarly, emotional or hostile aggression in humans could be considered the analogue of defensive aggression in response to a threat or perceived threat.
No one--and I mean, no one--has a clue what drove this man to commit his heinous crimes. What we do know is that he planned his hellish introduction into our psyches for months beforehand, carefully accumulating all the accouterments needed to generate a national and personal nightmare. What we also know is that he carefully planned his violent act; it was not, like an autistic meltdown, an act of the moment, an unplanned reaction

And you're wrong on some other counts as well, demonstrating the real dangers of a weapon like yours in the hands of the uninformed. You said that the minute you heard about the shooting, you knew it would be young white male, probably from "an affluent neighborhood." While being young, white, and male may fit the profile of many serial killers, mass murders are a different breed. They come from different backgrounds and ethnicities, but most share a single motivation: revenge. When they go beyond personal connections in their targets and kill total strangers, that revenge is usually against a society the killer thinks has wronged him. 

Other features in common are being male, being a "loner," and feeling alienated from the world. For the record, "autistic" does not equate with "loner" or "male," as much as you or the news media would like to distort it into that mold. Research, such as it is, suggests that the more a killer goes impersonal and targets strangers, the more likely a mental illness is to be involved. While that mental illness is usually paranoid schizophrenia, we must all remember that there are many, many more murderers in this world who are not schizophrenic than there are schizophrenics who commit this kind of violence. The coupling is not inevitable or even common. Indeed, better predictors of violence are unemployment, physical abuse, and recent divorce. The killer in the Aurora case had recently in effect become unemployed, having left graduate school and done poorly on spring exams. 

I'll close with this final observation: Autism is a disorder that is present from birth or very soon after. There are, however, other mental disorders and mental breaks that occur, particularly in young men and particularly at vulnerable developmental periods like adolescence and early adulthood. Not only does autism not fit here simply by virtue of its lifelong presence, but also, it's not something that just kinda shows up when a man turns 24 years old. 

The man who destroyed so many lives showed several signs of extreme stress prior to his murderous rampage. Were these stressors the trigger for him? That, I cannot say. But I can say that stress does not bring on autism in one's 20s, and autism at any age doesn't lead to carefully calculated revenge killings of innocent strangers. So, Joe, why don't you just put down your weapon and back away... as quickly as you can.
