[edit] A false belief?
Firstly, well done. However, I am somewhat unhappy with one aspect of this article. For me it is the quality of the way the belief is held that is paramount. The belief does not have to be false. This is discussed in the article but I cannot see an acceptance in the article that a delusional belief may be true from the outset and yet still delusional. Let me give an example to clarify what I mean. A man with delusional jealousy about his wife presents and describes his concerns that his wife is unfaithful. He has the classic features. He presents clearly psychotic reasoning for his justifications, e.g. stains on her underwear are proof, her occasional looks outside the window are to see if her lover is there. You interview the wife and find that she had a brief affair a year before the onset of the husband's condition but there is no way that he could know about this. True his belief is of an ongoing affair and you could say that therefore his belief is false, but let's extend it and consider the case where the wife IS having an affair. The husband though is clearly psychotic in the way that he holds the belief. Now, one way to test this is to say it is the fixity of the belief but I do take the points in the article on this subject. I am afraid though in practice that this is probably the main deciding factor for me and many other psychiatrists I know. But how to express this in an article? --CloudSurfer 07:07, 16 Sep 2004 (UTC)

- Since writing the above I have had a look at one of the references given in the article. I do not have access to the full article but it would appear from the abstract that it is dealing with the issue above. --CloudSurfer 05:24, 20 Sep 2004 (UTC)

- Hi there CloudSurfer,
-
- The initial sentence describes delusions as false beliefs as this is the everyday definition of a delusion. It then goes on to discuss the psychiatric definition which although currently does include the criterion of a delusional belief being false (as per the current DSM definition), it also requires that the belief be held in a certain way (again as outlined in the article).
-
- In terms of your point about delusional jealousy, I think the following paragraph covers this quite well:
-
- In other situations the delusion may turn out to be true belief. For example, delusional jealousy, where a person believes that their partner is being unfaithful (and may even follow then into the bathroom believing them to be seeing their lover even during the briefest of partings) may result in the faithful partner being driven to infidelity by the constant and unreasonable strain put on them by their delusional spouse. In this case the delusion does not cease to be a delusion, because the content later turns out to be true.
-
- However, I agree it could be clearer in explaining a belief may be true from the the start and still be diagnosed as delusional. However, as the diagnostic criteria for a delusion are at best, confused, and at worst, incoherent, meaning there is no adequate final definition (as the Spitzer article makes clear).

"Many religious beliefs hold exactly the same features, yet are not considered delusional." --- POV and not even accurate. Many atheists and others consider religious beliefs to be delusional. And Nietzsche said, of faith: "...a casual stroll through the lunatic asylum shows that faith does not prove anything." --195.93.21.98 02:23, 24 October 2005 (UTC)
Whole books could be written on this issue. It is very difficult to identify which of our beliefs are actually justified. Is an unjustified belief necessariy delusional? Does a delusional belief have to be harmful in some way to earn the epithet?
Examples
1. I believe God exists
- as an atheist I would say this belief is unjustified by the evidence. But is it harmful? Is it delusional?
2. I believe I can fly unassisted
- again an unjustified belief (though it can only be disproven by experiment!). Most people would call it delusional. Does it matter, though, as long as one doesn't attempt to act on the belief and try to fly off a cliff?
It should be pointed out that belief (1) can cause also people to do extremely dangerous things - hijack planes and fly them into buildings, launch crusades, persecute heretics. The same could be said of some political beliefs - that one's nation is a master race, or that violent revolution is necessary to obtain a just society.
3. I believe my partner/parent/child loves me
Again, this might be unjustified by the evidence. If so is it delusional? Might we depend on such unjustified beliefs such as this for our mental and emotional wellbeing?
No answers there I'm afraid. Which makes me wonder whether a "delusion" can be defined in terms other than subjective judgements.

- Similarly, it has always troubled me that a person could walk into a hospital and say "I saw demons yesterday" and immediately be committed to the psychiatric unit, but in many churches, the same statement would not be unusual. Kat, Queen of Typos 01:20, 23 January 2006 (UTC)
[edit] Knowing the delusion
We've all heard the axiom "crazy people don't think they're crazy". Is this untrue? Is it possible to have delusional thoughts, while knowing they're delusional? Example: if a person believed there was some unseen or unknown external intervention in their life (i.e. god, fate, aliens), but knew it was impossible.
What about contradicting beliefs, e.g. every potential mate they meet is in love with them and that they are not good enough for every potential mate or that they wouldn't want to be with them? Would that be considered to be delusional?
Just a couple of things I've been curious about.
Many things that we can not see and can not touch are true. e.g pain, love, soul, etc.
Knowing About Delusions from the Inside Out Rather Than Just Observed Behavior
I experienced a drug induced psychosis thirty-some years ago. I was able to with part of myself know what I was thinking may not be true, but the thoughts and feelings were so overwhelming it was hard to do anything more than ride out the psychosis. I did this by separating myself from the old environment, moving, and putting myself under house arrest. This was with a little outside help, and a lot of taking responsibility for my situation and hope that I would recover.
It is hard to for people who are suffering with delusions to do much more than to try to be opened minded. Delusions often appear to be deeply rooted. I know this from personal experience and working in Mental Health for the last 15 years. I think it wise to breach the subject that a delusion may be a false belief with a small amount of truth, but not belabor the notion.
I think it is importation to understand that delusions can be like a great wave that "rolls over the mind and engulfs it.” In my experience part of my thinking process understood the delusions I was having and how there was no “real proof” to back them up, but they were still overwhelming and the motivation of many of my thoughts and some actions.
take, for example, the classic instance of a person who thinks their thoughts can be heard by those around them - it's nonsensical! questions arise: would _i_ be able to hear _their_ thoughts? not necessarily. guess i better watch what i think. step further: they know my secrets and *must* know that i know; maybe the room going quiet as a thought private passes by is proof, but that's irrational, and yet, ultimately undeniable. the hold is unshakable. on some level, in some way, what cannot be, is. so what could cause this? a dread-inducing, cold-sweat-forcing fear of judgement, another example of the irrational? ultimately, would a person holding such beliefs want to stick around when not even his own mind is a haven from the judgement to which they irrationally, uncontrollably, and naturally overreact? maybe they speak very loudly the names of the ones who can hear in their mind to witness no reaction, and do so again in intervals expected to bewilder, to elicit a surprise reaction - only to fail. the delusion loses a lot of pull in the decisions and thought processes of the individual, but ready for the next delusional phase is the fact that the ones you're attempting to fool could once again be a step ahead, aware beforehand of your shouting ploy.
also, the perceived lack of privacy and implied negativity towards the self due to perceived, obsessive judgement could go a long way in explaining the personality loss commonly associated with schizophrenia, or at least, a cause. sorry for the rant.--Nod 08:34, 25 February 2006 (UTC)
[edit] Religious faith excluded?
Is it really excluded from the definition by psychologists? Is this a contentious issue within the field of psychology? Is the person who added that statement to the article delusional?

[edit] Robertson Panel
In the article Robertson Panel it mentions that shrinks are used to "reduce" interest in UFOs, aliens. Someone sued the CIA under the FOIA and got the information for the Robertson Panel, which it states that in a debunking campaign, psychiatrists are to be used, along with the media, and to spy on all UFO/alien organizations and groups. Martial Law 07:58, 18 April 2006 (UTC) :)
Since the docs are used, thus explains the "delusions" used to insult and ridicule people who have had these experiences as persuant to the Robertson Panel and Project Grudge protocol. Martial Law 08:00, 18 April 2006 (UTC) :)
Can this one be explained ? Martial Law 08:12, 18 April 2006 (UTC) :)
[edit] Animals inside of him??
"...and now realises that this person was laughing because the man has animals living inside him"...what does that mean? Figurative or his own delusion of animals? Le Anh-Huy 09:22, 22 April 2006 (UTC)

[edit] Primary and secondary delusions
Jaspers originally made a distinction between primary and secondary delusions.
According to Jaspers, primary delusions (sometimes called true delusions) are distinguished by a transformation of meaning, so that the world, or aspects of it, are interpreted in a radically different way by the delusional person. To others, this interpretation is 'un-understandable' in terms of the normal mental causality, mood, environmental influences and other psychological or psychopathological factors. Jaspers describes four types of primary delusion:
- delusional intuition - where delusions arrive 'out of the blue', without external cause.
- delusional perception - where a normal perception is interpreted with delusional meaning. For example, a person sees a red car and thinks that this means the person's food is being poisoned by the police.
- delusional atmosphere - where the world seems subtly altered, uncanny, portentous or sinister. This resolves into a delusion, usually in a revelatory fashion, which seems to explain the unusual feeling of anticipation.
- delusional memory - where a delusional belief is based upon the recall of memory or false memory for a past experience. For example, a man recalls seeing a woman laughing at the bus stop several weeks ago and now realises that this person was laughing because the man has animals living inside him.
Secondary delusions (sometimes called delusion-like ideas) are considered to be, at least in principle, understandable in the context of a person's life history, personality, mood state or presence of other psychopathology. For example, a person becomes depressed, suffers very low mood and self-esteem, and subsequently believes he or she is responsible for some terrible crime which he or she did not commit.
[edit] Possible Edits re: "Unfalsifiability", "Falsity", "Diagnostic issues", etc.
Re:
"Delusions do not necessarily have to be false or 'incorrect inferences about external reality' [2]. Some religious or spiritual beliefs (such as 'I believe in the existence of God') including those diagnosed as delusional, by their nature may not be falsifiable, and hence cannot be described as false or incorrect [3]."
What does the term 'unfalsifiable' mean, here? If it means necessarily true, then it is true that such a belief "cannot be described as false", but that God exists would hardly seem to be an example. If it means cannot be shown to be false, then that God exists might be an example (depending upon what God is conceived to be), but I see no reason to say that such beliefs "cannot be described as false or incorrect": it need not be the case that all falsehoods can be shown to be false. Perhaps the intent was to say that such beliefs cannot be known to be false (which is true if a belief must be capable of being shown to be false in order to be known to be false).
Re:
"In other cases, the delusion may be assumed to be false by doctor or psychiatrist assessing the belief, because it seems to be unlikely, bizarre or held with excessive conviction. Psychiatrists rarely have the time or resources to check the validity of a person’s claims leading to some true beliefs to be erroneously classified as delusional [5]. This is known as the Martha Mitchell effect, after the wife of the attorney general who alleged that illegal activity was taking place in the White House. At the time her claims were thought to be signs of mental illness, and only after the Watergate scandal broke was she proved right (and hence sane)."
This paragraph presupposes that delusional beliefs must be false despite the fact that the two immediately preceding paragraphs were aimed at showing that delusional beliefs can be true (and succeed in that aim, I think). If it is intended that the paragraph not imply that delusional beliefs must be false, then '...leading to some true beliefs to be erroneously classified as delusional...' could be changed to '...leading to some beliefs being erroneously classified as delusional...', and '...only after the Watergate scandal broke was she proved right (and hence sane)...' could be changed to either '...only after the Watergate scandal broke was she proved right, which made it seem unlikely that her allegations evinced mental illness...' or '...which made it plausible that her allegations were well grounded...'.
Moreover, since the paragraph is about the erroneous classification of beliefs as delusional, '...the delusion may be assumed to be false...' would be better rendered as '...a belief may be assumed to be delusional...'.
Finally, the entire section entitled "Diagnostic issues" seems to suffer from a failure to adequately distinguish between the following distinct issues:
(1) Whether the proposed definition succeeds in capturing all and only the cases of delusional belief in some "intuitive" sense of 'delusional belief'. (The notion that there are "counterexamples" to a definition presupposes that there is a pre-existing concept of which the definition is supposed to be an articulation.)
(2) Whether the proposed definition defines a condition which is unacceptably susceptible of misdiagnosis.
Perhaps these two issues ought to be treated in two separate sections. Hemlock 22:36, 24 April 2006 (UTC)
[edit] Grammatical error?
"Some religious or spiritual beliefs (such as 'I believe in the existence of God') of some, including those diagnosed as delusional, by their nature may not be falsifiable, and hence cannot be described as false or incorrect."
Of some, the words I emboldened, are not in the article, but I think they should be because the sentence doesn't make sense without them. Someone correct me if I'm wrong, or correct the page if it's wrong.

[edit] Idea of delusions in Buddhist teachings
Delusions are an important element in Buddhism. I was surprised there was no reference to the idea of Buddhist delusions in this article. Would it be appropriate to add this? --Raymm 16:58, 21 March 2007 (UTC)
- I've never heard that before. What would you use as a citation?--DorisHノート 17:03, 21 March 2007 (UTC)
Ok, this might take me a little while, but I'll get you something authoritative for you to consider. --74.100.172.207 02:42, 29 March 2007 (UTC)
For example: "Delusion: A mental factor that arises from inappropriate attention and functions to make the mind unpeaceful and uncontrolled. There are three main delusions: ignorance, desirous attachment and anger. From these arise all the other delusions, such as jealousy, pride, and deluded doubt." p 197, "The New Meditation Handbook", Geshe Kelsang Gyatso ISBN 0948006 91 9 --Raymm 16:10, 5 April 2007 (UTC)
