The Ksenia Psychopathy Checklist is a list of traits that describe psychopathy.
Psychopathy is an affective phenomenon.
We take behavior into account only as a means to assess affective traits.
We capture full psychopathy.
Although we also capture trait psychopath, this is secondary. Partial manifestations will not meet all Core-1 criteria, by design.
Psychopathy is an adaptive (beneficial) phenomenon.
We conceptualize psychopathy as an adaptive (beneficial) difference in personality (specifically, affect) that is reflected in psychophysiological reactivity, with some neutral traits. There is no implication of criminal behavior nor inherently maladaptive (mentally ill, pathological) traits.
Our foremost criterion is face validity.
Statistical validity is auxiliary and mostly used to organize questions and abbreviate the questionnaire.
The KPCL is a built on theoretical–semantic consierations
That is: We think about what each item means in psychological terms. The KPCL is a tool to understand and study how psychopaths think. The KPCL thus answers questions like:
How does it feel to be a psychopath?
How do psychopaths think?
Why do psychopaths do what they do, based on how they think?
We consider statistical results (results of factor analysis, external correlates of psychopathy questionnaires, etc.) only as a suggestion.
The KPCL does not contain a built-in variology or typology.
Instead the KPCL is the foundation. A variology can be built on top based on statistical data churning (empirical approach), theoretical–semantic model or combination thereof.
The KPCL subsumes the dark tetrad
Grandiose narcissism is part of Dominance—Grandiosity.
The concept of Machiavellianism in the dark tetrad is simply psychopathy conceptualized as cold and calculating instead of hot headed.
Sadism is included in items Sadism and Sadistic coziness. In addition, so-called “subclinical sadism” is included in items Enjoys having power and control over other people, Wrathful Hostility.
The KPCL is developed by Ksenia, an independent researcher that is a psychopath herself.
Ksenia has a privileged understanding from analyzing psychopathy in a detached matter-of-fact way incorporating both own experience and existing information from the literature.
The KPCL can be directly used for assessment.
Any person experienced in psychiatry and in particular with the concept of psychopath can use the KPCL to evaluate any person including herself. When used for self-assessment each item should be evaluated from a detached matter-of-fact viewpoint.
The KPCL can be used to develop questionnaires.
The KPCL is not a questionnaire since it is written in conceptual terms, not specific questions. It can be used to develop psychopathy self-report questionnaires or observed-rated questionnaires.
The hierarchical structure is a matter of convenience.
An hierarchical structure is used primarily to organize the presentation of the list of traits and make them easier to remember, think about and talk about. Although an attempt has been made to make the hierarchical structure semantically–theoretically meaningful, there is no implication that it is the only correct one.
The KPCL is a living work. Living work means the model changes to incorporate improvements to the model itself and to the description. Thus we update the description in this page. This is analogous to living standards related to the Internet and articles in a wiki.
In addition to the living version, we plan to eventually publish a stable version in a new web page in this web site. Subsequent versions may be occasionally published as required.
The list of items elaborates as needed for assessment.
Commentary on why a particular item was chosen go into the Development section.
1.1 Level of importance of items
Each item has a level of importance:
Core-1: Required.
Core-2: Not required. Considered part of psychopathy. Missing traits indicate incomplete psychopathy.
Complementary (Comp): If present, considered part of psychopathy. Missing traits do not indicate incomplete psychopathy.
Given a candidate trait, we ask ourselves: “If a person have less or none of this trait, do we say she is less of a psychopath?”. if not, then that should not be included in the definition of psychopathy, but merely as a correlate.
1.2 Rating scale
Assign a score to each item as follows:
Absent or minimal (0)
Partial (1)
Full (2)
1.3 The list of items
Some items have points. Points are suggestions to guide the evaluator. Use points to have an idea of what things to look for. Do not assign scores to each point. Ignore points according to judgment, especially when they are not applicable given the circumstances of the subject or when the evaluator knows of a more compelling reason to score the item than the points.
1.3.1 Coldness
Other names: Callosity–Unemotionality, Emotional Reactivity (R).
These items refer to emotional blunting, especially absence of negative emotions under threats to the self or to others. However, items that fit this description are placed within another subscale if they fit better. Items about the presence of an emotion (e.g.: sadism as opposed to absence of concern for the suffering of others) do not belong here.
Absence of empathy [Core-1]
Subject does not have empathy (a.k.a. “affective empathy”), i.e.: Does not feel negative emotions vicariously or for the mere fact that another person is suffering. Witnessing other’s suffering is humorous, annoying or indifferent for the subject.
Me and my friends were outside school when one classmate was hit in front of us by a car. I laughed. Some of my friends jumped. Some were distraught. Later they expressed they felt sorry for the accidented classmate.
Low arousal [Core-1]
Finds boring activities that keep most people engaged. Finds engaging activities that are highly arousing or requires stimulants to find activities engaging. Becomes bored doing the same activity.
I am bored most of the day.
I thought people were being metaphorical when they say “I am shaking from happiness”. I have never experienced that.
If I won the lottery, I would be like “Ok, good but it is not a big deal.”.
Points
Pervasive boredom
Reduced joyous excitement
Does not become elated by positive events or the expectation of positive events to the point of jumping, compulsively telling all contacts or having similar extreme immediate celebratory behavior.
Courageous or fearless [Core-1]
Unlike Stress resilience this is specific to fear in the sense of an overwhelming response of avoidance to an immediate and well-defined threat. E.g.: Fear of pain, fear of animals, fear of confrontation, fear of death.
It is stupid to fear death. It is literally nothing. You feel nothing being dead. It is the same as before you were born. Why would I be scared of that?
Cold aggression [Core-1]
Does not need to feel emotions in order to antagonize.
Absence of guilt [Core-1]
Absence of unconditional emotional love (as opposed to logical love) [Core-1]
If the subject feels love, it is always for people that do something for the subject. The love is experienced as a logical desire to have a mutualistic relationship with the other person.
Absence of somatic empathy [Core-1]
Subject does not experience negative emotions or a negative physical reaction to witnessing physical harm to other people including gore.
Emotional detachment [Core-2]
Able to reason and act about things matter-of-fact, i.e.: using logic without becoming emotionally involved. E.g. Judging the Russian invasion of Ukraine without taking sides.
Stresss resilience [Core-2]
Has no extreme emotions in situations that put pressure in most people to the point they react irrationally or freeze like accidents, shoot-outs and armed combat. Keeps control over herself. Does not find the situation traumatic during or after the fact.
Points:
Becomes focused under situations that cause stress to normies instead of blocking.
Capacity to ignore pain [Core-2]
Can ignore at least moderate pain so that it is felt and it hurts but does not affect the mental state of the subject. The intense form of this item is partial pain asymbolia: the subject is not hurt by at least moderate pain, i.e.: feels the sensation of pain but there is no annoyance whatsoever.
Grey rage [Core-2]
Reduced or absent red rage.
Includes reduced or absent emotional grudges.
Absence of depression in the strict sense [Core-2]
Anhedonia is not part of depression. Having anhedonia by itself does not disqualitiy somebody from this item.
Blunted or absent sadness [Core-2]
1.3.2 Tough Stance
These items refer to a tough judgment, i.e.: valoration of strength of character, rejection of weakness. Although Tough Stace is related to Coldness, Tough Stance is about viewpoint and thus primarily given by reasoning while Coldness is exclusively about emotions, namely emotional blunting.
Coldheartedness [Core-1]
P: I find it stupid and annoying that people make a big deal about commemorating the WTC attack, the Holocaust and similar.
No detached concern for the welfare of others overall. This is different from empathy. The following are not counted against this item:
Detached concern for people that are useful for one’s interests.
Detached concern in a mutualistic relationship.
Detached concern for particular people coming from a mutualistic relationship with said people. E.g.: A psychopath may have detached concern for friends and {family that do things for her}.
Detached concern coming from the psychopath’s activities. E.g.: A medic psychopath may have detached concern for patients in as much as providing adequate treatment for them.
Competitive jungle worldview (CJW) [Core-2]
A.k.a.: predator-prey worldview, social darwinism, drastic realism, competitive jungle belief. There are many ways to express this including:
There is predator and prey. If you are not a predator, you will be prey.
I do not care about justification. I do things because I can and I want.
Inherent rights do not exist. There only exists the will to do and the power to impose your will.
Losers deserve no help.
Fundamental strength [Core-2]
Fundamental strength means rejecting one’s weaknesses.
No blanket trust [Core-2]
Does not believe that people are trustworthy by default. Subject can trust a person if she has evidence that said person is trustworthy. Does not blindly trust authorities. Is reasonably skeptical of professional’s and expert’s opinion instead of taking it as the final word.
Radical realism [Core-2]
There is no point to hope to things to be different for how they are since hope does not make them so, actions do.
Values logic over emotions [Core-2]
Antiemotionality [Comp]
Disgust from people expressing intense emotions.
It annoys me when people die because a family member dies. What do they think they are going to accomplish with that? It just makes things worse for them.
The worst part of my birthday is when people give me their “best wishes”. I have to pretend I am thankful for that. How do “best wishes” benefit me? They do not. Just give me the gift and shut up.
People donate to charities to delude themselves that they are doing something good. That does not make them good in any way. It makes them stupid. Most charities are useless.
Radical accountability [Comp]
You are responsible for your conditions and your actions. If you are depressed, that is your fault for letting things get to you. If you did wrong what I asked of you then you earned a punishment, no excuses. If you did something stupid while being drunk then you are stupid. Control yourself or do not drink.
1.3.3 Dominance–Grandiosity
These items are related to a view of oneself as superior at the expense of others which supports a tendency (not just capability) to put down and exploit others for one’s benefit. This is in contrast with viewing oneself as not fundamentally better than others and treating others as peers.
High sense of self [Core-1]
Subjects sees herself in a positive image and better than others. Is self-confident/{secure in herself}. Is prideful and this pride is self-assured, not dependent on validation (a.k.a. hubristic pride).
The extreme form of this is grandiose sense of self: The subject consistently feels greater-than-life: A sense of being a goddess and any combination of perfect, invincible, infallible, immortal, far above human capabilities, the only conscious being in the universe, being the purpose of the universe, possessing an epistemologically privileged viewpoint (w.r.t. other intelligent agents), etc. Not to be confused with psychosis. Although the subject feels greater than life, she rationally knows this is not reality.
Egoistical [Core-1]
Is primarily concerned with own welfare, not morals, ideology or similar. To score full it is not required that the subject only concern is her own welfare. Is willing to cause a negative utility for others and fail obligations in order to obtain a positive utility for herself.
Psychopathy is ego-syntonic [Core-2]
If the subject is not aware that she is a psychopath evaluate whether the traits in this checklist are ego-syntonic. The subject does not wish to be normal and does not see psychopathy (or the traits) as a defect. For example: The subject sees not having empathy as positive.
Ego not dependent on praise and criticism [Core-2]
Manipulative [Core-2]
We define manipulation as eloquent talking directed to make the listener do what one wants. Note that manipulation does not necessarily involve lying.
The subject manipulates whenever it is required for her goal. This item does not require the user to always manipulate.
No distress during lying [Core-2]
Subject is confident of her manipulation skills and therefore feels no distress during lying. Absence of guilt (including as part of lying) is in a separate item.
Domineering–authoritative [Core-2]
Tends to tell other people what to do with an authoritative tone and has a willingness to coerce other people into doing what one wants. Note that this includes exploitation but is not limited to exploitation. It also includes giving recommendations with an authoritative tone and a tendency for grooming.
Points
An authoritative interpersonal style. A preference for the grammatical imperative (e.g.: “Do this”) instead of “Could you please do X?”.
Willingness to coerce people into doing what one wants. “Either you wash the dishes or we break up. I can find another one like you.”.
A tendency for motherliness/grooming, i.e.: Giving suggestions and steering other people’s lives towards one’s own idea of how they should conduct themselves, as opposed to mere suggestions. E.g.: “Quit your job and invest in cryptocurrency.”.
Contempt for people [Comp]
Most people are idiots/worthless/useless. In a crowd, I feel like being in the middle of a garbage dump.
90 % of people are mentally defective. They are worse than animals because they have the ability to use reason but choose to go with their impulses and feelings instead.
Enjoys having power and control over other people [Comp]
Respect is earned, not deserved [Comp]
Includes disliking following orders from unworthy authority.
Sadism [Comp]
Pure sadism or sadomasochism. It comes from enjoying power over other people and feeding one’s ego. It does not come from hatred of the victim.
It does not quality if the subject feels hot manic as a result of aggression. E.g. Feeling “bubbly” when stabbing somebody and seeing blood ooze does not qualify.
Sadistic coziness [Comp]
Subject experiences relaxation, calmness, peace or cozyness from observing the suffering of others either in-person, in media or in imagination.
I like imagining walking among a “forest” of people impaled in poles screaming and writhing in agony. It feels peaceful, like the coziness of a warm blanket in a cold day.
Leadership [Comp]
When working in groups subject has a tendency to be the official or de facto leader.
Difference with Domineering: Domineering refers to a style of interaction and can be evident in a single minutes-long interaction. Leadership is a role one adopts among a group and stays consistent through months or as long as the group lasts.
Arrogant affect [Comp]
Subject is confident of her own capability and when free to speak, readily mentions it in an exhibitionistic way.
Friend: I followed your advice and it worked. You were right.
Psychopath: I always am.
When people tell me I am very intelligent I say “I know.”. People have told me that since I can remember. It is no compliment, it is just a fact.
1.3.4 Asociality
Other names: Social disconnect, social indifference.
Reduced peer pressure/Does not care about social acceptance [Core-2]
Points
The subject is skeptical of the importance of issues talked about in mainstream media. E.g.: That SARS-CoV-2 warrants generalized fear and suspensionn of activities.
The subject is blunt to the point of being offensive as a side effect when there is nothing at stake because of being indifferent to whether this is well received by the other person.
Is indifferent towards social norms [Core-2]
Points
Subject does not accept at face value claims of competence of expert figures accepted by either mainstream or within groups she is member of. This does not refer to conspiracy theories. Conspiracy theories show lack of skepticism.
Absence of loneliness [Core-2]
Does not feel loneliness when alone.
Absent or reduced shame [Core-2]
If shame is present, it is mild and short-lived.
Blunted or absent indignation [Core-2]
Absence of envy [Comp]
Instrumental social relationships [Comp]
Social contacts are for a purpose. Entertainment is a possible purpose.
1.3.5 Irresponsability
These items have in common a prioritization for short-term reward over long-term consequences. This is related to the low pole of Big Five conscientiousness.
Wrathful hostility [Core-2]
Subject has a taste for confrontation and a desire to antagonize people for its own sake. Subject keeps control over whether to act on this desire. When acted on, it is cold aggression rather than aggression out of uncontrolled reactive emotions.
Irresponsability [Comp]
Finds difficult to impossible to perform activities because of obligation instead of intrinsic reward. Includes being unwilling to have an ordinary job, i.e.: with pre-defined working hours and that involve following orders.
Parasitic [Comp]
Obtains things at the expense of others instead of acquiring them with own labor.
Impatience [Comp]
Sensation seeking [Comp]
Prolonged boredom leads to performing entertaining/interesting activities that are costly or risky in order to relieve the boredom.
I was very bored so I induced serotonin syndrome on myself on purpose to see how it is like.
I went out in the night looking for something to set fire to.
Carefree [Comp]
Has little to no aprehension about the negative consequences of rewarding actions.
No ideological investment [Comp]
1.4 Pitfalls of evaluation
Female-to-male transsexual
We have found that natal women with antisocial traits that used FTM HRT in the past or use it in the present invariably have a fragile ego and thus are not psychopaths (Item High sense of self).
Sissies
We have found that male to female transsexuals that are attracted to men because of the false premise that men are the strong sex are BPD and thus not psychopaths (many items).
Art
We have found that style of art appreciation highly correlates with emotionality. Highly emotional people tend to like art that portrats “muh emotions” and vague concepts including abstract visual arts and poetry. Cold people tend to like art that portrays reality or an idealized version of reality, possibly with minor decorations. Said minor decorations do not opaque the realism. For example: Non-realistic colors in otherwise visual art.
View of women
Opinion/ideology/worldview is a posteriori
People who have compassion also expect the world to be compassionate with them
Coldness vs numbness
Reason vs emotion
To-do: Add my experience with telling people to describe things objectively.
**Does not take delusional insight from 5-HT2A agonists at face value.
Fear and freezing as part of inhibition, fearlessness as disinhibition.
Switchiness as a sign of emotinoal unstability
Antisocials vs psychopaths
Not spiteful
1.5 Development
1.5.1 Conceptualization
Conceptual traits, not the actual checklist:
Social dominance
Me at the expense of others.
Augmented narcissism
I am the most important person in the world. Others’ function is to serve me.
Much reduced or absent social contagion
Just because other people all agree on a judgment means nothing to me.
Egoism
Just because doing X instead of Y is better for society does not mean I will do X.
Cold rationality
Weak people suffer and die from their weaknes. That is a fact. I will not feel the pain of weak people but I feel my pleasure and my pain. Therefore I will act so as to maximize my pleasure and minimize my pain.
Competitive jungle worldview
There are predators and prey. Be a predator or else you will be prey.
Fearlessness or intense courageousness
1.5.2 Differentiation between subscales and items
Coldness vs Tough Stance
Both subscales include an absence of concern for others. Coldness is primarily affective while Tough Stance is judgmental.
Overly specific questions
Asking an overly specific question like “I would enjoy skydriving” and generalizing this to openness to experience. A subject may answer “No” because “It would ruin my hair.” despite being open to experience. This can be partially countered by including several such questions but gives a lower score arbitrarily to subjects that have the problematic answer.
Assuming that non-criminal psychopathy is a less intense manifestation
The KPCL is for full psychopathy. Moreover, we believe the criterion is stronger than all criteria for psychopathy used for both criminal and non-criminal populations. (E.g.: Aileen Wuornos would not pass a screening in Harpies Nest).
1.6 Ideas
Ideas under consideration.
(Question) I like being tested because I can show off my strength.
When I help people it is because I am bored, to make them dependent on me, to earn their favor, to build something intersting.
Detached concern instead of empathy.
(Question) I like using people’s own words to hurt them.
(Question) I find it funny when I accidentally break something that is not mine in front of the owner.
Blunted or absent hatred.
Disgust of people (I find it annoying to be next to normies, like smelling garbage.).
Engineer worldview
When somebody tells me her problems, I automatically think of how to solve them and tell her.
If a friend tells me she has a headache, I would rather tell her to take medication than to say “I hope you get better.”.
Inverted bright triad.
Not being a sore loser if the other party is not a sore winner.
Boxer attitude: Can delimit antagonism to the conflict itself and remain emotionally unaffected, like a boxer.
Radical solutions.
(?) Escalate to deescalate.
(?) Passive aggressive.
(?) Sadism is cute.
People have always called me a psychopath and I thought they were exaggerating.
Keeps control under mania.
Keeps control when under sedatives (e.g.: ethanol).
Preferred indifference.
No interest in conventional monogamy.
I do not require people to let me. I take what I want.
Minimal to none cognitive dissonance.
Face goes immediately to resting after laughing.
Violence and other’s suffering is relaxing and the tingles.
Absence of cringe feeling.
Absence of awkwardness feeling.
Narcissism (subset of traits):
I would only submit to somebody who is really strong.
I only provide proof of my mertis to people who have a legitimate reason to demand proof, never to protect my ego.
People are toys, tools or noise for me.
Most people are inferior to me.
Usually, if I have nothing to gain by pretending, I treat people as inferior to me becaue they are.
Worldview (subset of traits):
Anti-egalitarianism (???)
Empathy is weakness.
Rejection of weakness in oneself and others.
(Complementary) Stoicism.
(Complementary) Hedonism (???).
Owning one’s own actions. Perceived as cynism (I lied).
Caring about others as property (I would risk my life to protect a person I really like because she is mine).
Virtues are not superrational as in “if everybody did this, the world would be better”, but rather out of convenience or narcissism.
People care too much about things and that is a mistake. They end up causing suffering to themselves.
Rejection of blind altruism.
Rejection of rights.
Being very selective with whom one receives emotional comfort from, or altogether always rejecting it.
Human life has no intrinsic value.
Being antisocial in a calculated way is better than being antisocial out of impulsiveness. E.g.: Calculated murder should not be given a harsher sentence that impulsive murder. If anything, impulsive murderers should be punished for the stupidity.
(Question) If you walk on a dark alley and are raped, you have nobody to blame but yourself.
(Question) Give people enough rope to hang themselves with.
(Question) Pushing depressed people to suicide is good.
(Question) Better to die on your feet than to live on your knees.
Dimitri-Nietzsche (Fighting well is more important than the cause you fight for).
Trolley problem: When asked for what is the right thing (in a prosocial sense) is not averse to cause harm for the common good. Thus tends to utilitarianism, although may hold some deontological principles not based on empathy but on honor.
Reduced allegiance to groups born into.
Also include tentative physiophysical traits:
Diminished startle w.r.t nons.
Diminished instead of increased startle in presence of depictions of violence.
The tingles with respect to dominance and violence.
Low resting rate.
Higher level of endogenous μ-opioids or sensitivity of μ-opioid receptor OR of cannabinoid receptors.
Paradoxical response to dopaminergic stimulants.
Reduced sensitivity to DMT (?).
Physicalist view of delusional insight of serotonergic hallucinogens.
Do an impression management subscale:
I am incapable of feeling anything like love.
I am incapable of caring about people in any way.
I never do things for others.
I hate society and I would enjoy killing people.
I would love shooting a school.
Society are assholes (ASPD+BPD butthurt).
TO-DO: Sadism impression management.
I do not have emotions.
I can see myself becoming a serial killer.
Idea: Killing overemphasis, e.g.: I think about killing people most of the day.
Idea: Killing and torturing specifically, e.g.: There is certain people that deserve to be tortured and I would enjoy to be the one to torture them.
Idea: Deserving.
I wish I could understand and relate to people (autism).
I never help anybody.

2 List of psychopathy questionnaires and related
Questionnaires and checklists for psychopathy and neighboring concepts.
Do not use! Not introduced in the literature and there are no studies assessing any validity of this scale. Moreover, it conflates aggression with hot aggression.
This questionnaire has a dubious factor structure. Many factor models have been published. Some derived scales including only a subset of items of increased consistency have been published.
It is noteworthy that positive-scored items have a higher difficulty (in the meaning of item response theory) than negative-scored items. See for example Ray (2016) Positive and Negative Item Wording and Its Influence on the Assessment of Callous-Unemotional Traitshttps://www.researchgate.net/publication/279456470.

The authors did not give an explicit questionnaire. Instead, they defined an index of psychopathy based on the scores on facets of the NEO-PI-R. Although this implicitly results in a list of questions from which a questionnaire can be extracted, the point of the FFPI is that any questionnaire which evaluates the given FFM facets can be used to evaluate psychopathy.

My knowledge and experience tells me that the social world we live in is basically a competitive ‘in which the fittest survive and succeed, in which power, wealth, and winning are everything, and might is right.
It’s a dog-eat-dog world where you have to be ruthless at times.
Life is not governed by the ‘survival of the fittest’, we should let compassion and moral laws be our guide (R).
You know that most people are out to ‘screw’ you, so you have to get them first when you get the chance.
The best way to lead a group under one’s supervision is to show them kindness, consideration, and treat them as fellow workers, not as inferiors (R).
If one has power in a situation, one should use it however one has to in order to get one’s way.
All in all it is better to be humble and honest than important and dishonest (R).
Money, wealth and luxury are what really count in life.
Charity (i.e., giving somebody something for nothing) is admirable, not stupid (R).
It is much more important in life to have integrity in your dealings with others than to have money and power (R).
If it’s necessary to be cold blooded and vengeful to reach one’s goals, then one should do it.
Honesty is the best policy in all cases (R).
There is really no such thing as ‘right’ and ‘wrong’. It all boils down to what you can get away with.
Do unto to others as you would have them do unto you, and never do anything unfair to someone else (R).
Basically people are objects to be quietly and coolly manipulated for one’s own benefit.
