Are Psychopaths Dangerous Social Predators A Closer Look at the Evidence

[Music]

the serial killer ted bundy became a

global spectacle when he was prosecuted

for his gruesome crimes on live

television

as these live pictures unfolded many

people quickly realized that there was

something mysteriously different about

bundy

wendy generally came across as a

sensible and charming

kind person which are all qualities that

many of us seek out in partners and

friendships

but then there were moments where bundy

would arrogantly mock the court

proceedings while also showing a

chilling disregard for the victims and

their families

bunny even decided to serve as his own

attorney

discarding every legal advice he was

given

effectively self-sabotaging his chances

in court

he was later found guilty and sentenced

to death with the judge famously

describing bundias

extremely wicked shockingly evil and

vile

according to experts in forensic

psychology

ted bundy was absolutely no ordinary

offender

he exemplifies what they clinically

refer to as a psychopath

psychopaths has have been described as

social predators

who are completely lacking in conscious

and in feelings for others

psychopathic individuals may seem normal

as

did bundy but this outer appearance of

normality is just a carefully

constructed play act

it’s an imitation if you will it’s their

way of

masking an underlying predatory

personality profoundly deprived of a

moral compass

today the most relied upon method to

clinically assess

or identify psychopaths like ted bundy

is the so-called hair psychopathy

checklist revised

or in short the pclr this diagnostic

checklist consists of 20 personality and

behavioral items meant to describe a

stereotypical psychopath

for example the checklist describes

psychopathic personality as

grandiose remorseless shallow and

lacking empathy

and their behavior is described as

socially parasitic

impulsive and criminally versatile

in practice the checklist is used by

assessing to

what degree a patient matches these 20

traits

if there’s a substantial degree of

resemblance

such a person is then clinically

diagnosed as a psychopath

for comparison forensic psychologists

often describe

ted bundy as a near perfect match

many judiciary and correctional systems

across the world

including the us and canada acknowledge

the use of the pclr

and this is because psychopaths are

believed to be qualitatively different

from ordinary offenders

but how different are psychopath really

you might ask

and why are these alleged differences

relevant in the legal context

according to the developers of the pclr

psychopaths deviate from the average

offender in at least three

fundamental ways which in turn may or

may not influence their legal processes

first psychopaths are believed to be

extremely dangerous

so for example if if an offender is

clinically diagnosed as a psychopath

this may inform the decision on whether

the offender should be

admitted into a high-risk facility or

whether he should be granted parole

secondly it’s commonly believed that

psychopaths don’t change

that they are unresponsive to treatment

and rehabilitation efforts

the psychopaths may therefore be

excluded from inmate rehabilitation

programs

and in the us for instance this belief

about chronicity has been also been used

to argue that juvenile psychopathic

offenders should be transferred into

adult courtrooms the

third and final claim is that

psychopaths lack

conscience that they don’t feel remorse

and empathy and

are therefore unable to make proper

moral judgments

this may inform a judge or a jury about

the offender’s character

which can impact a variety of decisions

such as the sentencing deliberation

it is largely because of these three

claims and their potential forensic

implication

that the pclr has been repeatedly called

the single most important

psychological assessment in the criminal

justice system

so far all of this sounds very intuitive

perhaps

there is a basic demand in the legal

system to manage

extremely dangerous offenders and the

pclr simply helps us identify who they

are

however while this way of using and

implementing the pclr

might seem intuitive it doesn’t

necessarily follow that it’s also

unproblematic

so why is that well consider

first that it is estimated that on a

global scale

hundreds of thousands of individuals are

assessed every year

using the pclr and many of these people

are

as a consequence of this diagnosis being

treated differently

in the criminal justice system so that’s

all clear

but here is a potential problem

if we treat psychopaths differently

based on the claims made by forensic

psychologists

that they are extremely dangerous

untreatable

without conscience then it’s absolutely

essential

that this is also true so if we actually

went ahead and scrutinized these three

claims

we should find that those who are

clinically diagnosed as psychopaths

also fit this general description at

least to some

reasonable or substantial degree

on the other hand if it turns out that

those individuals we diagnose

are in fact no more dangers than

ordinary offenders

then the use of the pclr would be

unjustified

and therefore amount to plain legal

discrimination

since it would mean that these hundreds

of thousands of individuals are still

being managed as if they are extremely

dangerous

such as for instance being placed in

high risk institutions

or being done by parole and so forth

this short analysis demonstrates how

high the stakes really are

when it comes to implementing a tool

like the psychopathy checklist

either the assessment is justifiably

contributing to

making society safer or it’s a vessel

for discriminatory practices

in theory only one of these two stories

can be true

so which one is it

approximately one and a half year ago my

colleagues and i set ourselves the task

of

thoroughly answering this basic question

where the psychopaths truly are

extremely dangerous untreatable and

without conscience

to do so we systematically reviewed the

past

25 years of research scrutinizing and

aggregating the results of hundreds of

studies

involving thousands of imprisoned

psychopaths

our study was recently published in the

peer-reviewed journal

psychology public policy and law and in

terms of the study’s content

it’s one of the most comprehensive

reviews ever to be published in the

field of psychopathy studies

and here’s what we found

in terms of assessing levels of

dangerousness in

psychopath this is typically done by

tracking and comparing

post-release recidivism so for example

if

psychopaths are faster than

non-psychopathic offenders to commit

new crimes after being released from

prison

this is then interpreted as higher

levels of risk or

dangerousness we found that there was

some

evidence that psychopaths compared to

average offenders

are statistically more likely to engaged

in

post-release criminal activities however

to our surprise

the data only suggested a weak to

moderately higher probability

to illustrate what this data actually

tells us

picture a hypothetical group of

offenders who

criminally recidivate at some point in

time after being released from prison

in this group some individuals will do

so after only a few weeks

where others will take much longer

perhaps even years

a normal distribution of this data may

look something like this

where the right side represents those

who recidivate

relatively quicker and to the left those

who are relatively longer to recidivate

if we compare this to the average data

on psychopathic offenders

the picture generally looks something

like this

obviously this is a simplified way of

representing the data

but as we can see these two groups have

far more in common than what

differentiates them

and i assume we can all agree that this

difference can hardly justify calling

the one group

ordinary offenders and calling the other

group extremely dangerous predators

now in terms of the second claim about

untreatability or chronicity

the way this is typically studied is to

compare whether

psychopaths make therapeutic progress or

whether

treatment programs have any positive

effects on criminal behavior

we found no evidence that psychopaths

are unresponsive to treatment and

rehabilitation efforts

actually there were positive results

across intervention methods that

mirrored progress in other offenders

this included positive gains from

cognitive and behavioral therapy

for example such as learning to better

control aggressive impulses

in short contrary to the common beliefs

that

psychopaths are chronic psychopaths

can actually be rehabilitated in similar

ways as other offenders

in terms of the third claim that

psychopaths are

morally incapacitated we were

particularly interested in studies that

analyze psychopaths conscience

empathy and moral judgments and here

we were quite frankly amazed by our

findings

and again not in a good way first

we were unable to find a single

empirical study

measuring conscience and psychopaths

this was especially surprising

since the most read and cited book about

psychopath

is entitled without conscience

how can scientists claim to know that

psychopaths lack conscience

if they have never attempted to measure

it

we then reviewed the research on

psychopaths capacity to empathize

for example a typical empathy study

measures whether psychopaths can

correctly

identify the emotion in facial

expressions

say the difference between sadness and

fearfulness

however not a single study showed the

psychopath had

any clear differences let alone severe

impairments of empathic capacities

finally we analyzed dozens of studies on

how psychopaths make

moral judgments this included research

on whether psychopaths perceive

moral situations differently as well as

studies testing responses to ethically

complex questions

for instance consider the question is it

morally permissible to steal medicine to

save a sick person’s life

well you might think that this is a

complex

question studies actually show that

there’s a remarkable similarity in how

most people answer such questions so if

psychopaths

really do lack a moral compass then it’s

at least reasonable to

expect that their answers could be

different

however across multiple studies

psychopaths did not show any

difficulties in making moral judgments

instead their performances merely

reflected those of

ordinary people

our study is the first ever to take a

systematic and

integrative look into the three common

descriptions of psychopath

and there’s really no way we can

sugarcoat the results

we found that all three claims were

either largely or

entirely unjustified

what this actually means is that the

individuals we assess or

identify as psychopath in the criminal

justice system

for instance by using the pclr do not

actually

fit the common description of

psychopaths in other words

the narrative we tell about psychopaths

is simply not angered in reality

it’s nothing but fiction

now there’s an almost unimaginable

number of ways that this

fiction about psychopath can create

problems in the legal context

as mentioned it may contribute to parole

applications being denied or

affect sentencing recommendations but

consider

also that some studies in the us have

found

that describing a person as a psychopath

predicts juror support for capital

punishment

it’s likely that using the checklist in

some cases

could be a matter of life and death

obviously these type of decisions

or any other forensic decisions for that

matter

should not be based on fiction and when

we mistakenly do so

this ought then to be rectified in one

way or the other

right if this is the case

if this is our viewpoint then it’s quite

possible that we have in front of us

a problem which could have overwhelming

legal

professional and ethical consequences

because what do we do with cases where

the pclr has played a defining role

should denied parole applications be

re-evaluated

must we allow guilty individuals to

request a new trial on the ground of

prejudicial

evidence what about psychopathic

juveniles who were transferred to adult

courts

should they be transferred back if so

what if they are no longer in the

adolescence

and how will all of this impact the

credibility of our profession

now some of you might be asking yourself

here towards the end

is he really telling me that the ted

bundies of our communities are no more

dangerous than other

criminals of course not obviously there

are people out there

that are more dangerous than others and

nothing could be more evident when faced

with serial killers like ted bundy

but while we can easily call these

people psychopaths

it is an entirely different task to

develop instruments that can identify

them with scientific precision

something that the pclr aims to be doing

but nevertheless fails at

yet the assessment still has the legally

compromising effects on a presumably

vast number of people

therefore i believe you must immediately

halt and seriously reconsider the

current

widespread use of the hair psychopathy

checklist revised

thank you

] 连环杀手 ted bundy 因

在电视直播中犯下的骇人听闻的罪行而被起诉,成为全球瞩目的景象。

随着这些现场照片的展开,许多

人很快意识到,bundy wendy 有

一些神秘的不同,

通常给人的印象是一个

明智而迷人的人

这些都是

我们许多人在合作伙伴和友谊中寻求的品质,

但有时邦迪

会傲慢地嘲笑法庭

诉讼,同时也

对受害者及其家人表现出令人不寒而栗的漠视,

兔子甚至决定担任自己的

律师,

抛弃 他得到的每一条法律建议都

有效地自我破坏了他

在法庭上的机会

他后来被判有罪并被

法官判处死刑 根据法医心理学专家的说法,他

描述了邦迪亚

极其邪恶、令人震惊的邪恶和

卑鄙

特德邦迪绝对不是

他所例证的普通罪犯 他们在临床上

所说的 精神病

患者 精神病患者被描述为

完全缺乏意识

和对他人感情的社会

掠夺者

掩盖潜在的掠夺性

人格,严重剥夺了

道德指南针

今天最依赖的方法来

临床评估

或识别像 ted bundy

这样的精神病患者是所谓的头发精神病

检查表修订

或简而言之 pclr 这个诊断

检查表由 20 个性格和

行为 用于描述

典型精神病患者

的项目 例如,清单将

精神病患者的人格描述为

浮夸、无情、肤浅和

缺乏同理心

,他们的行为被描述为

社交寄生

冲动和犯罪多才多艺

s 这 20 个

特征,

如果有相当程度的

相似性

,那么这样的人就会在临床上

被诊断为精神病患者

以供比较法医心理学家

经常将

ted bundy 描述为几乎完美的匹配

,包括美国和加拿大在内的世界上许多司法和惩教系统

承认使用

这是因为精神病患者被

认为在性质上

与普通罪犯不同,

但是您可能会问精神病患者到底有多大不同,

以及为什么根据 pclr 精神病患者的开发者的说法,这些所谓的差异

在法律背景下

与普通

罪犯有很大差异 至少在三个

基本方面,这些方式反过来可能会或

可能不会影响他们的法律程序

第一个精神病患者被认为是

极其

危险的,例如,如果一个罪犯被

临床诊断为精神病患者,

这可能会告知

罪犯是否应该被

接纳的决定 进入高风险设施或

是否 r 他应该获得假释

其次,人们普遍认为

精神病患者不会

改变他们对治疗

和康复

工作没有反应,因此精神病患者可能会被

排除在囚犯康复计划之外

,例如在美国,这种

关于长期性的信念也被使用

争辩说青少年精神病

罪犯应该被转移到

成人法庭

第三个也是最后一个主张是

精神病患者缺乏

良心,他们不会感到自责

和同情

,因此无法做出适当的

道德判断,

这可能会告知法官或

陪审团 罪犯的

性格会影响

诸如量刑审议等各种决定,

这主要是由于这三个

主张及其潜在的法医

含义

,pclr 一直被反复称为

刑事

司法系统中

迄今为止最重要的单一心理评估所有这一切 听起来很

直观 e 是法律

体系中管理

极其危险的罪犯的基本要求,

pclr 只是帮助我们识别他们

是谁,

然而,虽然这种使用和

实施 pclr 的方式

可能看起来很直观,但并不

一定意味着它也

没有问题,

所以为什么

首先考虑一下,据估计,在

全球范围内

,每年有数十万人

使用 pclr 进行评估,其中许多人

由于这种诊断

在刑事司法系统中受到不同对待,所以这

一切都很清楚,

但 这是一个潜在的问题,

如果我们根据法医心理学家的说法对精神病患者进行不同的治疗

,即他们非常危险,没有

良心是无法治疗的

,那么这也是绝对

必要的

,所以如果我们真的

继续仔细检查这三个

说法,

我们应该会发现 那些被

临床诊断为精神病患者的人

也符合这个一般描述

另一方面,如果事实证明我们诊断出的

那些人实际上并不比普通罪犯更危险,

那么至少在某种合理或实质性的程度上,那么使用 pclr 将是

不合理的

,因此构成明显的法律

歧视,

因为它会 意味着这

数十万个人仍然

受到管理,就好像他们非常

危险

,例如被安置在

高风险机构

或被假释等等。

这个简短的分析表明

当涉及到 实施

像精神病检查表这样的工具,

要么评估是合理地

有助于

使社会更安全,要么是理论上

歧视性做法

的容器,这两个故事中只有一个

是真实的,

所以

大约一年半前我的

同事和 我为自己设定

彻底回答

精神病患者的基本问题的任务 确实

非常危险,无法治疗,而且

没有良心

这样做 我们系统地回顾了

过去

25 年的研究,仔细审查和

汇总了

涉及数千名被监禁的

精神病患者的数百项研究的结果

我们的研究最近发表在

同行评审期刊

心理学公共政策和法律上 就该

研究的内容而言,

它是

有史以来在精神病研究领域发表的最全面的评论之一

,这是我们

在评估精神病患者的危险程度方面发现的结果,

这通常是通过

跟踪和比较

释放后的累犯来完成的 因此,例如,

如果

精神病患者在出狱后比非精神病患者更快

地犯下

新罪行,

那么这将被解释为更高

水平的风险或

危险性,我们发现有

一些

证据表明,与普通罪犯相比,精神病患者

在统计上更有可能 从事

发布后 e 犯罪活动 但是

令我们惊讶

的是,数据仅显示出较弱到

中等较高的概率

来说明该数据实际上

告诉我们的

情况

仅在几周后这样做

,其他人可能需要更长的时间,

甚至可能需要几年时间

。这些数据的正态分布可能

看起来

像这样 将此与精神病罪犯的平均数据进行比较

,图片通常看起来

像这样,

显然这是表示数据的一种简化方式,

但正如我们所见,这两个群体

的共同点远多于

区分他们的地方

,我认为我们都可以同意 这种

差异很难证明将

这一组称为

普通罪犯 s 并

根据关于不可治疗性或慢性性的第二个说法现在称另一组为极其危险的掠食者。

通常研究的方式是

比较

精神病患者是否取得治疗进展或

治疗计划是否

对犯罪行为有任何积极影响,

我们没有发现任何证据表明 精神病

患者对治疗和

康复工作

没有反应 实际上

,干预方法

取得了积极的结果,反映了其他罪犯的进步,

这包括

认知和行为治疗

的积极收益,例如学习更好地

控制攻击性

冲动,这与精神病患者的普遍信念相反

慢性精神病

患者实际上可以以与其他罪犯类似的方式康复

,就第三项主张而言,

精神病患者在

道德上无行为能力 我们

分析精神病患者的良心

同理心和道德判断的研究特别感兴趣,这里

w 坦率地说,我们对我们的发现感到非常惊讶,

而且首先

我们无法找到一项

衡量良心和精神病患者的实证研究,

这尤其令人惊讶,

因为关于精神病患者的阅读和引用最多的书

的标题是没有良心

,科学家们怎么能声称 要知道如果

精神病

患者从未尝试过衡量

它,他们就会缺乏良心,

然后我们回顾了关于

精神病患者移情能力的研究

,例如,一项典型的移情研究

测量了精神病患者是否能够

正确

识别面部表情中的情绪,

说出悲伤和恐惧之间的区别,

但不是 一项研究表明

精神病患者有

任何明显的差异,更不用说

移情能力的严重损害

最后我们分析了数十项

关于精神病患者如何做出

道德判断的研究,其中包括

关于精神病患者是否以

不同方式看待道德状况的

研究以及测试对道德行为的反应的研究

例如,复杂的问题 考虑这个问题在

道德上是否允许偷药来

挽救病人的

生命 你可能认为这是一个

复杂的

问题 研究

实际上表明,大多数人回答这些问题的方式有显着的相似性,

所以如果

精神病患者

真的这样做 缺乏道德指南针,那么

至少可以合理地

预期他们的答案可能会

有所不同,

但是在多项研究中,

精神病患者

在做出道德判断时并没有表现出任何困难,

相反,他们的表现仅仅

反映了普通人的表现,

我们的研究是第一个

对 并

综合研究精神病患者的三种常见

描述

,我们真的无法

粉饰

我们发现所有三种说法

在很大程度上或

完全不合理的结果

这实际上

意味着我们

在刑事司法中评估或认定为精神病患者的个人

系统

例如通过使用 pcl r

实际上并不

符合对精神病患者的常见描述,

换句话说

,我们讲述的关于精神病患者的叙述

在现实中根本没有被激怒,

它只不过是虚构的,

现在有几乎无法

想象的方式,这种

关于精神病患者的虚构可以

在法律背景下造成问题,

因为 提到这可能会导致假释

申请被拒绝或

影响量刑建议,但

也考虑到美国的一些研究

发现

,将一个人描述为精神病患者

可以预测陪审员支持死刑

,在

某些情况下使用清单

可能是一个问题

显然,这些类型的决定

或任何其他有关该事项的法医决定

不应基于虚构,当

我们错误地这样做时,

如果是这种情况,

则应该以一种或另一种权利来纠正 我们的观点那么很

可能我们面前有

一个可能已经结束的问题 压倒性的

法律

专业和道德后果,

因为我们如何处理

pclr 发挥决定性作用的案件

应该拒绝重新评估假释申请

我们是否必须允许有罪的个人以

偏见

证据为由要求重新

审判 被转移到成人

法庭

如果他们被转移回来

如果他们不再处于

青春期怎么办?所有这些将如何影响

我们职业的可信度

现在你们中的一些人可能会问

自己,

他真的在告诉我吗

我们社区的 ted bundy 并不

比其他

罪犯更危险,当然并不明显

有些人

比其他人更危险,

当面对像 ted bundy 这样的连环杀手时,没有什么比这更明显了,

但是虽然我们可以很容易地称这些为

人们精神

病态者

开发可以

用 s 识别他们的工具是一项完全不同的任务 科学精确度

pclr 旨在做的事情,

但仍然失败,

但评估仍然对可能大量的人产生法律上的

妥协影响,

因此我相信你必须立即

停止并认真重新考虑

目前

广泛使用的头发精神病
