What? Why? I think most of us assume people who go on mass shooting sprees have some kind of mental instability.

I see your background is mental health. Instead of just throwing out these cryptic "holier than thou" one-liners, you would do your cause (whatever it is) a lot more justice if you would actually explain your point of view rather than just trying to look like some kind of sage.

People incorrectly link mental illness to violence. Most violence, even spree killings, is not committed by someone with a mental illness. Mental illness is not a predictor of violence. (A previous episode of violence is; a drug or alcohol addiction is, but a mental illness, even a severe and enduring mental illness is not) People with a mental illness are very much more likely to be the victims, not perpetrators, of violence.

By linking mental illness to violence you stigmatize people with a mental health problem. This stigma makes people less able to seek help from professionals or friends or even family. People become irrationally scared of those with a mental illness and don't know how to offer help. Employers are less likely to offer employment to those with mental illness.

> I think most of us assume people who go on mass shooting sprees have some kind of mental instability.

But that's just ignorance caused by people who continue to lazily assume and then state that anyone who is violent is also mad - even if there's nothing to support that.

This is possibly an example of the conjunction fallacy. We see violence and cannot explain it, and so when we think "is this person violent, or violent and has a mental illness?" we end up at "violent and with a mental illness" even though it's less likely than "just violent".

Linking mental illness to violent crime is as lazy and ignorant as Fox news linking violent crime to African Americans, with the same mangling of statistics and undue focus on very rare events and lack of focus on common events.

Here is a small representative sample of contradictory cases:

You didn't bother reading the post, did you?

Tucson: "Loughner had been arrested (but not convicted) once on a minor drug charge[11]" - drug addiction combined with mental illness is the predictor here. The mental illness alone was not predictive.

https://en.wikipedia.org/wiki/Jared_Lee_Loughner

> Acquaintances said that Loughner's personality had changed markedly in the years prior to the shooting, a period when he was also abusing alcohol and drugs.

Again: drug or alcohol addiction are reasonable predictors of violent behaviour. Mental illness alone is not a reasonable predictor of violence.

Mental illness is common. It would be unusual for there to be no mass murders with a mental illness. All you're doing is lazily ignoring all the very many murders committed by people who do not have a mental illnes o focus on a tiny minority committed by people who do have a mental illness; and then you're ignoring the actual predictors of violent behaviour which are previous violence or drug / alcohol addiction.

There's a difference between linking mental illness to violence and linking violence to mental illness.

[DanBC]

That difference doesn't exist when you talk to people about their perceptions of mental illness and violent behaviour. They think that people with a mental illness are likely to be violent, even though that's very unlikely. They think that a violent event will have been perpetrated by a person with a mental illness even though again it's not likely.

[freehunter]

That's their problem then, not the problem of the parent author. If you think video games are real life and shoot someone because Call of Duty made you do it, you have a mental illness. No where did anyone here make the claim that everyone with a mental illness would do that though.

I drink tea because I have a cold. Not everyone who has a cold drinks tea, though. I'm guessing that mental illnesses might be a sensitive subject for you for some reason, but being overly politically correct isn't the answer to solving the social stigma. You can't deny that people who have trouble separating fiction from reality have a mental illness.
