Back in 2002, I had a little piece published on excessive collecting behaviour in the Guardian newspaper (‘Addicted to hoarding’). In it I wrote:
“I have always been interested in why we have what seems like an innate ability to collect. I would almost go as far as to say that we are ‘natural born hoarders’. Furthermore, there has been surprisingly little research in this area and Freud’s theories on the topic are unfortunately almost empirically untestable. I would also add that for some people, collecting is at the pathological end of the behavioural continuum. There are some that are (for want of a better word) ‘addicted’ to collecting and there are some with obsessive-compulsive disorders who simply cannot throw away anything”.
Since then I’ve published a few articles on the psychology of collecting in this blog and is probably one of the reasons that I have had a few approaches over the last couple months from journalists asking me about the psychology behind various forms of collecting. (In fact, I’ve also been approached to write an academic chapter on the phenomenon too). Two of the most recent media requests included journalists writing articles on why people collect retro video games (which I hope to write about in a future blog) and another on why people collect ‘sexual trophies’.
I have to admit that I am no expert on sexual trophies so I did a little reading on the topic. According to one definition I came across, a sexual trophy is “any item or piece of clothing gained from a sexual encounter as proof of a successful sexual conquest”. To tie in with the release of US comedy I Just Want My Pants Back, MTV conducted a [non-academic] survey and reported that one in three young British people (aged between 18 and 34 years) admitted to owning some sort of sex trophy with one in six of them (16%) claiming they had two or more sex-based trophies (a group that MTV termed ‘Sexual Magpies’).
However, when it comes to the collecting ‘sexual trophies’, I would argue that most academic research that I have come across on the topic relates to more criminal sexual deviance rather than day-to-day sexual encounters. For instance, in the 2010 book Serial Murderers and Their Victims, Dr. Eric Hickey described the case of man – who was a voyeur – from Georgia (US) that used to break into houses and steal women’s underwear. On his eventual arrest they found over 400 pairs of knickers that he had stolen. More disturbing are cases such as this excerpt from a story in the Daily Telegraph. This is arguably more typical of what I perceive to be sexual trophy hunters:
“A company manager and ‘pillar of the community’ has been exposed after 20 years as a serial sex attacker known as the Shoe Rapist. James Lloyd, 49, a long-standing Freemason who took the footwear of his victims as trophies, was finally caught through advances in DNA techniques. Police later found more than 100 pairs of stiletto shoes hidden behind a trap door at the printing works where he was employed… As well as taking their shoes, he often stole jewellery from the women, mainly in their teens and early 20s, between 1983 and 1986” (Daily Telegraph, July 18, 2006).
However, Dr. Hickey’s book describes even worse acts of sexual trophy collecting. He noted that many serial killers are “known for their habits of collecting trophies or souvenirs. Others have collected lingerie, shoes, hats, and other apparel”. A sizeable section of the book concentrates on the types of serial killers that are popular in the media (such as those that commit ‘lust murders‘) and are the subject of many Hollywood films such as the series of films with (my favourite fictional psychopath) Hannibal Lecter. As Hickey notes:
“These are the rapists who enjoy killing and, often, indulging in acts of sadism and perversion. These are the men who have engaged in necrophilia, cannibalism, and the drinking of victims’ blood. Some like to bite their victims; others enjoy trophy collecting – shoes, underwear, and body parts, such as hair clippings, feet, heads, fingers, breasts, and sexual organs…[and] evoke our disgust, horror, and fascination”.
One of the cases discussed is 1950s US serial killer Harvey Glatman (known in the media as ‘The Lonely Hearts Killer’) who used to take photographs of the women he murdered. Citing the work of Dr. Robert Keppel (another expert in serial murder cases and author of Serial Murder: Future Implications for Police Investigations), Dr. Hickey wrote:
“His photos were more than souvenirs, because in Glatman’s mind, they actually carried the power of his need for bondage and control. They showed the women in various poses: sitting up or lying down, hands always bound behind their backs, innocent looks on their faces, but with eyes wide with terror because they had guessed what was to come”.
Other murderers described by Dr. Hickey included a man that liked to surgically remove (and keep) the eyeballs from his sexual victims (most probably 1990s’ serial killer Charles Allbright) and another that skinned his victims and made lampshades, eating utensils, and clothing. In his overview of necrophilic homicide (i.e., those individuals that kill others in order to engage in sexual activity), Hickey also mentions that such necrosadistic murderers often engage in other paraphilias related to necrophilia “including partialism or the desire to collect specific body parts that the offenders finds sexually arousing. This may include feet, hands, hair, and heads, among others”. Hickey also noted that:
“Another important characteristic of these lust killers was the ‘perversion factor’. This subgroup was often prone to carry out bizarre sexual acts. These acts most commonly included necrophilia and trophy collection. Jerry Brudos severed the breasts of some of his victims and made epoxy molds. Brudos, like others, also photographed his victims in various poses, dressed and disrobed. The photos served as trophies and a stimulus to act out again”.
Later in the book, Dr. Hickey examines the case of Jerry Brudos in more detail (please be warned that some of the things written here may offend those of a sensitive nature):
“At an early age, Jerry Brudos developed a particular interest in women’s shoes, especially black, spike-heeled shoes. As he matured, his shoe fetish increasingly provided sexual arousal. At 17, he used a knife to assault a girl and force her to disrobe while he took pictures of her. For his crime he was incarcerated in a mental hospital for 9 months. His therapy uncovered his sexual fantasy for revenge against women, fantasies that included placing kidnapped girls into freezers so he could later arrange their stiff bodies in sexually explicit poses. He was evaluated as possessing a personality disorder but was not considered to be psychotic…He continued to collect women’s undergarments and shoes. Prior to his first murder, he had already assaulted four women and raped one of them. At age 28, Jerry was ready to start killing…He took [his first victim] to his garage, where he smashed her skull with a two-by-four. Before disposing of the body in a nearby river, he severed her left foot and placed it in his freezer. He often would amuse himself by dressing the foot in a spiked-heel shoe. His fantasy for greater sexual pleasure led him…to strangle [another victim] with a postal strap. After killing her, he had sexual intercourse with the corpse, then cut off the right breast and made an epoxy mold of the organ. Before dumping her body in the river, he took pictures of the corpse. Unable to satisfy his sexual fantasies and still in the grasp of violent urges, he found his third victim…After sexually assaulting her, he strangled her in his garage, amputated both breasts, again took pictures, and tossed her body into the river”.
Arguably the most infamous ‘sexual trophy collector’ was 1980s US serial killer Jeffrey Dahmer, the so-called ‘Milwaukee Cannibal’. In Dr. Hickey’s account he noted that:
“Restraining Dahmer, the officers looked around the apartment and counted at least 11 skulls (7 of them carefully boiled and cleaned) and a collection of bones, decomposed hands, and genitals. Three of the cleaned skulls had been spray-painted black and silver. These were to be part of the shrine fantasized by Dahmer. A complete skeleton suspended from a shower spigot and three skulls with holes drilled into them were found throughout the apartment…Chemicals, including muriatic acid, ethyl alcohol, chloroform, and formaldehyde, were also discovered, along with several Polaroid photographs of recently dismembered young men. A complete human head sat in the refrigerator”.
Another infamous case from the early 1970s (that I admit I had never heard of until I read Dr. Hickey’s book) was Ed Kemper, a cannibalistic killer who also collected human trophies and keepsakes of his victims. Citing the book Hunting Humans by Dr. Elliot Leyton, it was reported that:
“At the age of 23, Ed started killing again, a task that would last nearly a year and entail eight more victims. He shot, stabbed, and strangled them. All were strangers to him, and all were hitchhikers. He cannibalized at least two of his victims, slicing off parts of their legs and cooking the flesh in a macaroni casserole. He decapitated all of his victims and dissected most of them, saving body parts for sexual pleasure, sometimes storing heads in the refrigerator. Ed collected ‘keepsakes’ including teeth, skin, and hair from the victims. After killing a victim, he often engaged in sex with the corpse, even after it had been decapitated. In his confession Kemper stated five different reasons for his crimes. His themes centered on sexual urges, wanting to possess his victims, trophy hunting, a hatred for his mother, and revenge against an unjust society (Leyton, 1986)”.
The most obvious question related to these depraved acts is why such people do it in the first place. Writing in the Encyclopedia of Murder and Violent Crime, Nicole Mott provides an answer:
“A trophy is in essence a souvenir. In the context of violent behavior or murder, keeping a part of the victim as a trophy represents power over that individual. When the offender keeps this kind of souvenir, it serves as a way to preserve the memory of the victim and the experience of his or her death. The most common trophies for violent offenders are body parts but also include photographs of the crime scene and jewelry or clothing from the victim. Offenders use the trophies as memorabilia, but also to reenact their fantasies. They often masturbate or use the trophies as props in sexual acts. Their exaggerated fear of rejection is quelled in front of inanimate trophies. Ritualistic trophy taking, as is found with serial offenders, acts as a signature. A signature is similar to a modus operandi (a similar act ritualistically performed in virtually all crimes of one offender), yet it is an act that is not necessary to complete the crime”
In one of my previous blogs on the psychology of collecting more generally, I referred to a paper by Dr. Ruth Formanek in the Journal of Social Behavior and Personality. She suggested five common motivations for collecting: (i) extension of the self (e.g., acquiring knowledge, or in controlling one’s collection); (ii) social (finding, relating to, and sharing with, like-minded others); (iii) preserving history and creating a sense of continuity; (iv) financial investment; and (v), an addiction or compulsion. She also claimed that the commonality to all motivations to collect was a passion for the particular things collected. Personally, I think that the acquisition of sexual trophies – even in the most deranged individuals – can be placed within this motivational typology in that such individuals clearly have a passion for what they do and I would argue that the behaviour is an extension of the self that to some individuals may be a compulsion or addiction.

I have just come back from a two-week holiday in Portugal and managed to catch up with reading a lot of non-academic books. Two of the books I took with me were Paul Trynka’s biography of Iggy Pop (Open Up and Bleed ) and Brett Callwood’s biography of The Stooges, the band in which Iggy Pop first made his name (The Stooges: A Journey Through the Michigan Underworld ). Just before I left to go on holiday I also read Dave Thompson’s book Your Pretty Face is Going to Hell: The Dangerous Glitter of David Bowie, Iggy Pop, and Lou Reed (2009). This engrossing reading has been accompanied by me listening to The Stooges almost non-stop for the last month – not just their five studio albums (The Stooges , Fun House , Raw Power , The Weirdness , and Ready To Die ) but loads of official and non-official bootlegs from the 1970-1974 period. In short, it’s my latest music obsession.
Although I say it myself, I have been a bit of an Iggy Pop aficionado for many years. It was through my musical appreciation of both David Bowie and Lou Reed that I found myself enthralled by the music of Iggy Pop. Back in my early 20s, I bought three Iggy Pop albums purely because they were produced by David Bowie (The Idiot , Lust For Life , and Blah Blah Blah ). Thankfully, the albums were great and over time I acquired every studio LP that Iggy has released as a solo artist (and a lot more aside – I hate to think how much money I have spent on the three artists and their respective bands over the years). Unusually, I didn’t get into The Stooges until around 2007 after reading an in-depth article about them in Mojo magazine. Since then I’ve added them to my list of musical obsessions where I have to own every last note they have ever recorded (official and unofficial). When it comes to music I am all-or-nothing. Maybe I’m not that far removed from my musical heroes in that sense. I’m sure my partner would disagree. She says I’m no different to a trainspotter who ticks off lists of numbers.
One thing that connects Pop, Reed and Bowie (in addition to the fact they are all talented egotistical songwriters and performers who got to know each other well in the early 1970s) is their addictions to various drugs (heroin in the case of Pop and Reed, and cocaine in the case of Bowie – although they’ve all had other addictions such as Iggy’s dependence on Quaaludes). This is perhaps not altogether unexpected. As I noted in one of my previous blogs on whether celebrities are more prone to addiction than the general public, I wrote:
“Firstly, when I think about celebrities that have ‘gone off the rails’ and admitted to having addiction problems (Charlie Sheen, Robert Downey Jr, Alec Baldwin) and those that have died from their addiction (Whitney Houston, Jim Morrison, Amy Winehouse) I would argue that these types of high profile celebrity have the financial means to afford a drug habit like cocaine or heroin. For many in the entertainment business such as being the lead singer in a famous rock band, taking drugs may also be viewed as one of the defining behaviours of the stereotypical ‘rock ‘n’ roll’ lifestyle. In short, it’s almost expected”.
Nowhere is this more exemplified than by Iggy Pop. Not only would Iggy take almost every known drug to excess, it seemed to carry over into every part of his lifestyle. For instance, reading about Iggy’s sexual exploits, there appears to be a lot of evidence that he may have also been addicted to sex (although that’s speculation on my part with the only evidence I have is all the alleged stories in the various biographies of him). Another thing that amazes me about Iggy Pop was that he decided to give up taking drugs in the autumn of 1983 and pretty much stuck to it (again mirroring Lou Reed who also decided to clean up his act and go cold turkey on willpower alone). Spontaneous remission after very heavy drug addictions is rare but Iggy appears to have done it. Maybe Iggy gave up his negative addictions for a more positive addiction – in his case playing live. David Bowie went as far as to say that playing live was an “obsessive” for Iggy. As noted in Paul Trynka’s biography:
“[His touring] was simultaneously impressive and inexplicable. David Bowie used the word’ obsessive’ about Iggy’s compulsion to tour – but there was an internal logic. Jim knew he’d made his best music in the first ten years of his career, and he also believed he’d blown it…but he knew his own excesses or simple lack of psychic stamina were a key reason why the Stooges crashed and burned. Now he had to still prove his stamina, to make up for those weaknesses of three decades ago”.
Iggy Pop is (of course) a stage name. Iggy was born James Newell Osterberg (April 21, 1947). The ‘Iggy’ moniker came from one of the early bands he drummed in (The Iguanas). I mention this because another facet of Iggy Pop’s life that I find psychologically interesting is the many references to ‘Iggy Pop’ being a character created by Jim Osterberg (in much the same way that Bowie created the persona ‘Ziggy Stardust’ – ironically a character that many say is at least partly modeled on Iggy Pop!). Many people that have got to know Jim Osterberg describe him as intelligent, witty, talkative, well read, and excellent social company. Many people that have been in the company of Iggy Pop describe him as sex-crazed, hedonistic, outrageous, a party animal, and a junkie (at least from the late 1960s to the early to mid-1990s). It’s almost as if a real living character was created in which Jim Osterberg could live out an alternative life that he could never do as the person he had become growing up. Iggy Pop became a persona that Jim Osterberg could escape into. When things went horribly wrong (and they often did), it was Iggy’s doing not Osterberg’s. It’s almost as if Osterberg had a kind of multiple personality disorder (now called ‘dissociative identity disorder’ [DID]). One definition notes:
“[Dissociative identity disorder] is a mental disorder on the dissociative spectrum characterized by at least two distinct and relatively enduring identities or dissociated personality states that alternately control a person’s behavior, and is accompanied by memory impairment for important information not explained by ordinary forgetfulness…Diagnosis is often difficult as there is considerable comorbidity with other mental disorders”.
I don’t for one minute believe ‘Jim/Iggy’ suffers from DID but a case could possibly made based on the definition above. Some of the things he did on stage in the name of ‘entertainment’ included gross acts of self-mutilation such as stubbing cigarettes out on his naked body, flagellating himself, cutting his chest open with knives and broken glass bottles. He was a sexual exhibitionist and appeared to love showing his penis to the watching audience. On one infamous occasion, he even dry-humped a large teddy bear live on a British children’s television show. (Maybe Iggy is a secret plushophile? Check out the clip on here on YouTube).
In 1975, Iggy was admitted to the Los Angeles Neuropsychiatric Institute (NPI) and underwent treatment (including psychoanalysis) under the care of American psychiatrist Dr. Murray Zucker. After he had completely detoxed all the drugs in his body, Iggy was diagnosed with hypomania (a mental affliction also affecting another of my musical heroes, Adam Ant). This condition was described by Iggy’s biographer Paul Trynka:
“Bipolar disorder [is] characterised by episodes of euphoric or overexcited and irrational behaviour, succeeded by depression. Hypomanics are often described as euphoric, charismatic, energetic, prone to grandiosity, hypersexual, and unrealistic in their ambitions – all of which sounded like a checklist of Iggy’s character traits”.
Dr. Zucker later told Paul Trynka that hypomania tends to get worse with age and it hadn’t with Iggy and therefore the diagnosis of a bipolar disorder may have been wrong. Dr. Zucker now wonders whether “the talent, intensity, perceptiveness, and behavioural extremes” of Iggy were who he truly was “and not a disease…that Jim’s behaviour was simply him enjoying the range of his brain, playing with it, exploring different personae, until it got to the point of not knowing what was up and what was down’. In short, Dr. Zucker (who maintained professional contact with Iggy during the 1980s) claimed Iggy was perhaps “someone who went to the brink of madness just to see what it was like”. Dr. Zucker also claimed that Iggy (like many in the entertainment industry) was a narcissist (“excessive for the average individual” but “unsurprising in a singer…this unending emotional neediness for attention, that’s never enough”). In fact, Iggy went on to write the song ‘I Need More‘ (and was also the title of his autobiography) which pretty much sums him up many of his pychological motivations (at least when he was younger).
It’s clear that Iggy has been drug-free and fit for many years now although many would say that all of his best musical work came about when he was jumping from one addiction to another – particularly during the decade from 1968 to 1978. This raises the question as to whether musicians and songwriters are more creative under the influences of psychoactive substances (but I will leave that for another blog – I’ve just begun some research on creativity and substance abuse with some of my Hungarian research colleagues). I’ll leave the last word with Dr. Zucker (who unlike me) had Iggy as a patient:
“I always got the feeling [Iggy] enjoyed his brain so much he would play with it to the point of himself not knowing what was up and what was down. At times, he seemed to have complete control of turning this on and that on, playing with different personas, out-Bowie-ing David Bowie, as a display of the range of his brain. But then at other times you get the feeling he wasn’t in control – he was just bouncing around with it. It wasn’t just lack of discipline, it wasn’t necessarily bipolar, it was God knows what”.

A couple of weeks ago I bought a secondhand copy of The Fortean Times Book of Weird Sex by Steve Moore (mainly because it cost me only one pence at an online book store). One of the stories (on pp.96-97) concerned a bizarre story of an autoerotic death involving an adolescent boy. I checked out the reference list at the back off the book to see where the story had originated and the source was listed as an Associated Press story from Knoxville (Maryland, USA). It didn’t take me too long to track down the press release on the internet. The report said:
“A 16-year old boy in Knoxville was found dead in his bedroom in what police describe as a gruesome, horrifying death. Firefighters were called to the scene Monday morning by a neighbor who smelled something burning. When the firemen found the remains of the teenager they called the police in to investigate. At first investigators believed that they were dealing with a ritualistic murder. Posters of heavy metal rock and roll groups covered his bedroom walls, groups which are often connected with satanic worship and rituals. According to a firefighter who was on the scene, the boy was found nude, with the remains of a cow’s heart attached to his genitals. Wires had been attached to the heart and plugged into a wall socket. The boy died from electrocution, then the electricity literally cooked his remains. Investigating Officer Hardaway dismissed the ritual murder theory when detectives found several underground pornographic magazines under the boy’s mattress. One of the magazines, called ‘Ovid Now’, describes a sexual ‘toy’ that can be made from the fresh heart of a cow, a simple electrical circuit, and some batteries. This deviancy is apparently gaining limited popularity in the rural South. Practitioners get the dead heart to beat, and then use the beating organ for sexual perversions. ‘This is one of the most gruesome things I have ever seen. I can’t believe that there are people who actually enjoy this sort of thing’ Hardaway commented. The boy’s parents are currently on vacation in Florida, where they were contacted and informed about the tragedy. They were unavailable for comment”.
As I have already written a previous blog on electrophilia and published an article on the ten strangest autoerotic deaths (in the magazine Bizarre) I thought it would make the basis for a good blog. However, after a bit more investigation I discovered the story to be a fake. The Snopes.com website (also know as the Urban Legends Reference Pages) investigated the story and showed it to be completely false. The author of the article (Barbara Mikkelson) wrote:
“The [cow heart masturbation story] isn’t a bona fide Associated Press article. No such death has been recorded, let alone been reported on by the Associated Press. What we have here is a work of fiction, an inventive leg-pull. Pranksters are everywhere, both on-line and off-line. In this case, someone took his best shot at presenting a gruesomely salacious story as a news item by dressing it up to mimic the style he assumed wire service copy adhered to, resulting in a laughable Associated Press pastiche”.
The same article also reported another fictitious tale of masturbatory death by animal (in this case a lobster). Here, the story was that a women had masturbated using a live lobster and that the lobster had defecated into her vagina, implanting brine shrimp eggs that then hatched inside her. Additionally, there are a few fictional cases in literature, the most infamous being the use of an animal liver as a masturbatory aid in Philip Roth’s 1969 novel Portnoy’s Complaint. The novel is basically the monologue of (as Wikipedia describes) “a lust-ridden, mother-addicted young Jewish bachelor who confesses to his psychoanalyst in intimate, shameful detail, and coarse, abusive language”. In my previous blog on sitophilia (sexual arousal from food), I did note that processed animal tissue has been used as a masturbatory aid (the most notable being botulinonia that involves the sexual use of sausages).
However, there is one case report in the scientific literature that is definitely true. It was published in a 1990 issue of the American Journal of Forensic Medicine and Pathology by Dr. Barry Randall, Dr. Richard Vance, and Dr. Timothy McAlmont and was simply titled ‘Xenolingual eroticism’. The paper described the case of a 29-year old female that presented at an abortion clinic saying that she had missed her periods and that she had a possible pregnancy that required termination. She was given a D&C (dilatation and curettage) and a muscular “pale grey tissue mass” measuring seven centimetres in length and 3 centimetres in diameter was found inside her vaginal passage. The object removed from her vagina turned out to be a deer tongue that the woman has been using as a masturbatory aid. At the time their case study was published, Dr. Randall and colleagues reviewed all the relevant literature on masturbatory practices in the Index Medicus database and found 42 papers (of which 27 detailed autoerotic deaths and 14 describing the psychology of autoeroticism). They then noted that:
“Only one reference reviewed various nonlethal autoerotic practices. Over a 42-year period, Aliabadi et al. recorded 18 patients, only three of whom were women, who presented with foreign body insertion for erotic purposes. All three women had inserted foreign bodies into the urinary tract. Acts of autoeroticism involving vaginal masturbation with foreign objects are perhaps more common. None to our knowledge have been reported because these do not result in death or injury, and typically would not come to medical attention. The literature discloses examples of foreign bodies extracted from the male and female lower urinary tract because objects of small diameter may be retracted by natural muscular impulses into the proximal urethra and/or bladder. Indeed, according to Kinsey and others >90% of foreign bodies found in the female bladder or urethra are there as a result of masturbation. Also, large objects retrieved from the vagina are found mostly in married women aged 17-30 [years]. However, these objects, most commonly bananas, cucumbers, and other large vegetables, rarely come to surgical attention. The medical literature reveals only seven references to bestiality. None of them deals with the issue of using nonviable animal tissue for autoerotic purposes. This report is presented so that xenoerotic objects may be placed on the list of possible masturbatory tools that may come to the attention of medical personnel”.
As far as I am aware, the case study by Dr. Randall and colleagues is the only academic paper on the use of animal tissue as a masturbatory aid. I did actually cite this study in a previous blog in relation to Dr. Anil Aggrawal’s 2011 typology of zoophiles in the Journal of Forensic and Legal Medicine. The case cited by Randall and colleagues could be classed as a fetishistic zoophile. According to Dr. Aggrawal, these individuals keep various animal parts (especially fur) that they then use as an erotic stimulus as a crucial part of their sexual activity. Obviously the use of a deer tongue is rare but appears to fit the definition of a fetishistic zoophile.

“Real happiness consists in not what we actually accomplish, but what we think we accomplish” (Charles Green Shaw, American abstract artist)
Ever since I can remember I have always been someone that compiled lists. Back in my youth it was lists of my favourite pop groups, film stars, sports stars, etc. I still make loads of lists but these days they are more likely to be long ‘to do’ lists (in fact, I’ve even written articles on getting the most out of ‘to do’ lists and being organized – see ‘Further reading’ below) or writing articles in the form of lists (in fact, I used to write what I called ‘psychol-lists’ for the British Psychological Society’s in-house magazine The Psychologist). When I make lists I feel more productive, and they are often the spurs to get things done (as long as I actually do the things on the list).
Obviously, list making can be an important activity in the organizational skills of many working individuals. Based on my own observations, most people make lists so they (i) don’t forget things, (ii) don’t procrastinate, (iii) feel in control and focused in what they are doing, (iv) can relieve stress, and (v) can cross things off the list and feel a sense of accomplishment. However, for a minority of people, making lists appears to be obsessive and a mental health issue. In short, there may be a fine line between being organized and being neurotic. From my own personal experience, I know that writing lists can be related to perfectionism. But life isn’t perfect and not completing activities on ‘to do’ lists can raise stress and worry levels. Ironically, the only way some people can deal with this is to make even more lists of things to do.
Obsessive list making is sometimes referred to as glazomania (check out the ‘Manias’ page at The Scorpio Tales website). Online dictionaries tend to define glazomania as either “a passion for list making” or “an unusual fascination with making lists”. However, the term ‘glazomania’ doesn’t appear to be used much academically. I did come across one recent paper in Distinktion: Scandinavian Journal of Social Theory, by Dr. Urs Staeheli that mentioned it:
“Recently, quite a number of coffee-table books have been published that collect different sorts of everyday lists. Some authors even speak of a ‘glazomania‘ (Cagen 2007) – that is, an uncontrolled urge to produce lists and a fascination with list-making”
However, there was no other information provided. I managed to track down the 2007 reference to Sasha Cagen’s book (To-Do List: From Buying Milk to Finding a Soul Mate, What Our Lists Reveal About Us). The book includes creative list-making exercises with the aim of helping individuals to “get in touch with their passion for life, inside and out of work, and refocus them on what brings them alive”. Cagen now makes a living on writing and giving workshops on the benefits of list making (one of her major clients being Google)
Although the term ‘glazomania’ is seldom used academically or clinically, obsessive list making is often mentioned as one of the symptoms of obsessive-compulsive disorder. As one online admission I came across noted:
“I have OCD, and recently my OCD flares up in the form of compulsive list making. This behavior totally affects my ability to be productive because I am constantly afraid of forgetting something and of spending time doing the wrong thing. Does anyone have any tips on how to break the cycle?”
The Wikipedia entry on obsessive-compulsive personality disorder notes that the main symptoms are “preoccupation with remembering and paying attention to minute details and facts, following rules and regulations, compulsion to make lists and schedules, as well as rigidity/inflexibility of beliefs or showing perfectionism that interferes with task-completion. Symptoms may cause extreme distress and interfere with a person’s occupational and social functioning” (my emphasis)
Psychologically, an argument could be made that obsessive list makers are simply trying to create an illusion of control in otherwise chaotic lives. The reason whyindividuals with OCD make lists compulsively is that they often afraid (in some cases, to the point of being phobic) that they will forget something important (even though research shows they do not have memory problems). These (arguably unnecessary) lists provide a reminder to carry out daily activities (i.e. brushing teeth, making breakfast, etc.). As with other OCD-type behaviours, the action of making a list helps the individual to feel psychologically better (albeit temporarily). The etiological roots may lie in the fact that the sufferer may at some point in their past history have been reprimanded severely, or repeatedly, by others for innocently forgetting things that were important. The OCD Types website adds:
“They never learn that they do not need the list to remember things. People with OCD may also make lists to remember things that may be contaminated to later wash or avoid, which also contributes to the OCD process. List-making can be in writing or verbalized aloud”.
In 2010, the BBC reported an exhibition at the Archives of American Art in Washington featuring lists made by eminent artists (everything from “scribbled on scraps of paper” to the “elaborately illustrated” including lists by Pablo Picasso, Alfred Konrad, Oscar Bluemner, Eerp Saarinen and Harry Bertoia). Bluemner even kept lists of lists. The curator of the exhibition (Liza Kirwin) told the BBC that:
“In trying to give order to his life, [Bluemner] obscures the clarity of the inventory of his work. He’s completely obsessed with this type of record keeping…This very mundane and ubiquitous form of documentation can tell you a great deal about somebody’s personal biography, where they’ve been and where they’re going. People can relate to this form of documentation because so many people are list keepers and organise their lives this way”.
In the same article, the BBC interviewed the US psychoanalyst Dr. Michael Maccoby who claimed that there are various types of list makers. However, there was little detail and the only quote in relation to types of list makers claimed: “The extreme is the obsessive who has to make lists of everything. These are people who have an unconscious fear that everything is going to be out of control if they don’t make a list”. As far as I am aware, there is no published empirical research on personality types and list making although there is some psychological literature showing that list making – as part of time management practices – appears to have some beneficial effects on both student grade point averages and workplace productivity.
Finally, a few months ago, an online article by Dr. Carrie Barron at the Psychology Today website provided a brief summary of why making lists is psychologically good for people. I’m not sure about the empirical basis of her claims but they seem to have reasonable face validity. I’ll leave you with her reasons (her verbatim list of “six great benefits”!). In summary, Barron believes that lists:
- “Provide a positive psychological process whereby questions and confusions can be worked through.
- Foster a capacity to select and prioritize. This is useful for an information-overload situation.
- Separate minutia from what matters, which is good for identity as well as achievement.
- Help determine the steps needed. That which resonates informs direction and plan.
- Combat avoidance. Taking abstract to concrete sets the stage for commitment and action. Especially if you add self-imposed deadlines.
- Organize and contain a sense of inner chaos, which can make your load feel more manageable”.

Throughout my career, I have constantly pointed out that I met very few people that are genuinely addicted to playing weekly or bi-weekly Lotto games. When stating this, some people counter my assertion that they know people who spend far too much money on buying Lotto tickets and that it is areal problem in their life. However, this is a classic instance of confusing ‘problem gambling’ with ‘gambling addiction’. These two terms are not inter-changeable. When I give lectures on gambling addiction I always point out that “all gambling addicts are problem gamblers but not all problem gamblers are gambling addicts”.
Nowhere is this more relevant than in the print and broadcast media. For instance, I have been one of the co-authors on the last two British Gambling Prevalence Surveys (published in 2007 and 2011). In these surveys we assessed the rate of problem gambling using two different problem gambling screens. Neither of these screens assesses ‘gambling addiction’ and problem gambling is operationally defined according to the number of criteria endorsed on each screen. For instance, in both studies we used the criteria of the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) to estimate the prevalence of problem gambling. Anyone that endorsed three or more items (out of ten) was classed as a problem gambler. Anyone that endorsed five or more items was classed as a pathological gambler. Pathological gambling is more akin to gambling addiction but we found only a tiny percentage of our national participants could be classed as such. What we did report was that 0.9% of our sample were problem gamblers (i.e., they scored three or more on the DSM-IV criteria).
What we didn’t say (and never have said) was that 0.9% of British adults (approximately 500,000 people) are addicted to gambling. However, many stories in the British media when they talk about problem gambling will claim ‘half a million adults in Great Britain are gambling addicts’ (or words to that effect). I am not trying to downplay the issue of gambling addiction. I know only too well the pain and suffering it can bring to individuals and their families. Also, just because I may not define a problem gambler as being genuinely addicted (by my own criteria as outlined in a previous blog), that doesn’t mean that their problem gambling might not be impacting in major negatively detrimental ways on their life (e.g., relationship problems, financial problems, work problems, etc.).
However, returning to the issue of being ‘addicted’ to Lotto games I have always stated in many of my published papers on both addiction and (more specifically) gambling addiction, that addictions rely on constant rewards. A person cannot be genuinely addicted unless they are receiving constant rewards (i.e., their behaviour being reinforced). Playing a Lotto game in which the result of the gamble is only given once or twice a week is not something that can provide constant rewards. A person can only be rewarded (i.e., reinforced) once or twice a week. Basically, Lotto games are discontinuous and have a very low event frequency (once or twice a week). Continuous gambling activities (like the playing of a slot machine) have very high event frequencies (e.g., a typical pub slot machine in the UK has an event frequency of 10-12 times a minute). Gambling activities with high event frequencies tend to have higher associations with problem gambling, and are more likely to be associated with genuine gambling addictions.
That doesn’t mean people can’t spend too much money buying lottery tickets. Buying ticket after ticket can indeed lead people to have a gambling problem with Lotto. However, I know of no addiction criterion that relates to the amount of money spent engaging in an activity. Obviously the lack of money can lead to some signs of problematic and/or addictive behaviour (such as committing criminal activity in order to get money the person hasn’t got to gamble) but this is a consequence of the behaviour not a criterion in itself. In most of the behavioural addictions that I carry out research into (exercise addiction, sex addiction, video game addiction, etc.), there is little money spent but some of these behaviours for a small minority of people are genuinely addictions.
One of the reasons I felt the need to write this article was a press release I saw the other day from the Salvation Army in New Zealand. The story basically said that for some people, playing Lotto was an addictive activity. Here are some of the things the press release said:
“The Salvation Army Problem Gambling service is seeing an increase in the number of clients for whom Lotto products has become a problem for them and their families. ‘When it becomes an addiction, gambling creates havoc in people’s lives’, says Commissioner Alistair Herring, National Director of Addiction Services. ‘The gambling of some of our clients has led to criminal offending, domestic violence, loss of the family home, and – most commonly – children going without food and other basic needs. Regrettably, some people are unable to buy a simple product like a Lotto ticket without it leading to harm for themselves and others. A Lotto ticket can seem harmless but once their purchase becomes an addiction the results can be devastating’…In the past year, The Salvation Army problem gambling programme assisted over 1400 clients most of whom used Lotto. Fifty-seven clients said Lotto was the most significant aspect of their gambling problem. ‘This sort of sales promotion without fully understanding the damage the product can have on an individual and their family is irresponsible. New Zealand is moving toward food labelling that identifies additives dangerous to health. Yet Lotto tickets are sold without any warning that they can lead to health dangers through addiction’. One of the results of Lotteries Commission activity is that Countdown supermarkets recently started selling Lotto tickets at the checkout”.
Many of you reading this may think I am being a little pedantic but while I don’t doubt that buying too many Lotto tickets can be problematic if the person buying them simply can’t afford it, the resulting behaviour is ‘problem gambling’ not ‘gambling addiction’. In relation to my own criteria for addiction, the only way someone could be addicted to Lotto was if they were actually addicted to the buying of the tickets rather than the outcome of the gamble itself. This is not as bizarre as it sounds as some research that I carried out in the late 1990s and early 2000s with Dr. Richard Wood appeared to show that a small proportion of adolescents (aged 11 to 15 years) were addicted to playing both Lotto and scratchcard lottery games.
While it is theoretically possible for kids to be hooked on lottery scratchcards (as you can play again and again and again if you have the time, money, and opportunity), we found it strange that adolescents should have ‘addiction’ problems with Lotto. However, in follow-up qualitative focus groups, some adolescents reported that they actually got a buzz from the buying of Lotto tickets and scratchcards because it was an illegal activity for them (i.e., only those aged 16 years or older can play lottery games in the UK so the buying of tickets below this age is a criminal offence). Basically, there was a small minority of kids that were getting a buzz or high from the illegality of buying a lottery ticket rather than the gambling itself.
Along with Michael Auer, I published a paper in the journal Frontiers in Psychology where we argued game type was actually irrelevant in the development of gambling problems. We provided two examples that demonstrate that it is the structural characteristics rather than the game type that is critical in the acquisition, development and maintenance of problem and pathological gambling for those who are vulnerable and/or susceptible. A ‘safe’ slot machine could be designed in which no-one would ever develop a gambling problem. The simplest way to do this would be to ensure that whoever was playing the machine could not press the ‘play button’ or pull the lever more than once a week. An enforced structural characteristic of an event frequency of once a week would almost guarantee that players could not develop a gambling problem. Alternatively, a risky form of lottery game could be designed where instead of the draw taking place weekly, bi-weekly or daily, it would be designed to take place once every few minutes. Such an example is not hypothetical and resembles lottery games that already exist in the form of rapid-draw lottery games like keno.
Although many people (including those that work in the print media) may still use the terms ‘problem gambling’ and ‘gambling addiction’ interchangeably, hopefully I have demonstrated in this article that there is a need to think of these terms as being on a continuum in which ‘gambling addiction’ is at the extreme end of the scale and that ‘problem gambling’ (while still of major concern) doesn’t necessarily lead to problems in every area of a person’s life.

In a previous blog on five ‘weird addictions’ I briefly mentioned pagophagia, a craving and compulsion for chewing ice. Pagophagia is a type of pica (which I also covered in a previous blog). Pica is defined as the persistent eating of non-nutritive substances for a period of at least one month, without an association with an aversion to food. Although the incidence of pagophagia appears to have increased over the last 30 years in westernized cultures, Dr. B. Parry-Jones (in a 1992 issue of Psychological Medicine) carried out some historical research and pointed out that both Hippocrates and Aristotle wrote about the dangers of excessive intake of iced water. Parry-Jones also noted that references to disordered eating of ice and snow were also recorded in medical textbooks from the sixteenth century. However, the first contemporary reference to pagophagia appears to have been a 1969 paper by Dr. Charles Coltman in the Journal of the American Medical Association entitled ‘Pagophagia and iron lack’.
Pagophagia is closely associated with iron deficiency anemia but can also be caused by other factors (biochemical, developmental, psychological, and/or cultural disorders). If pagophagia is due to iron deficiency (such as case studies of those with sickle cell anemia), it may sometimes be accompanied by fatigue (e.g., being tired even when performing normally easy tasks). Dr. Youssef Osman and his colleagues published a number of case reports of pagophagia in a 2005 issue of the journal Pediatric Haematology and Oncology including the case of a child with sickle cell anemia and rectal polyps (that caused a lot of bleeding and made the anemia worse):
“An 8-year-old Omani boy, a known case of sickle cell anemia…presented with history of craving for ice. The child was noticed over the last 4 months to like drinking very cold water and to open the deep freezer and scratch the ice and eat it. The parents tried to stop him from doing so, but they failed…The child was started on oral iron therapy…and his craving for ice was completely stopped. Meanwhile, the rectal polyp was removed surgically”.
Other potential health side effects include constant headaches (a ‘brain freeze’ similar to ‘ice cream headache’) and teeth damage although this is thought to be relatively rare. However, a recent paper by Dr. Yasir Khan and Dr. Glen Tisman in the Journal of Medical Case Reports highlighted the case of a 62-year-old Caucasian man who presented with bleeding from colonic polyps associated with drinking partially frozen bottled water.
Khan and Tisman also suggested that some people who are deficient in iron experience tongue pain and glossal inflammation (glossitis). Others claim that chewing ice may help those with stomatitis (i.e., inflammation of the mucous lining inside the mouth). A recent 2009 case study published by Dr. Tsuyoshi Hata and his colleagues in the Kawasaki Medical Journal, reported the case of a 37-year old Japanese women who ate copious amounts of ice to relieve the pain of temporomandibular joint disorder (i.e., chronic pain in the joint that connects the jaw to the skull). Khan and Tisman also claim that the classical symptoms of pagophagia have changed in the last 40 years since Dr. Coltman’s initial paper in the Journal of the American Medical Association.
“This may probably be the result of advances in technology and changes in culture. When initially described [by Coltman], pagophagia was defined as the excessive ingestion of ice cubes from ice trays and the ingestion of ice scraped from the wall of the freezer. With the advent of ice cube makers and auto defrosters, the presentation of pagophagia has changed in a subtle manner as described in…our patients. Now we observe a subtler ingestion and/or sucking of ice cubes from large super-sized McDonald’s-like cups and from the use of popular bottled water containers that have been frozen”.
There have been few epidemiological studies examining the prevalence of pagophagia. Such estimates vary widely within particular populations but (according to Dr. Youssef Osman and his colleagues) have been shown to be more common in low socioeconomic and underdeveloped areas. Pagophagia is thought to be relatively harmless in itself or to one’s health, although there are some claims in the literature that pagophagia can be addictive. However, empirical reviews suggest that pagophagia (and pica more generally) is part of the obsessive-compulsive disorder spectrum of diseases. As a consequence, some case studies even suggest that ice chewing compromises their ability to maintain jobs or personal relationships.
Treatment for pagophagia can often be overcome with iron therapy and Vitamin C supplements (to supplement iron deficiency if that is the cause). For instance, Dr. Mark Marinella in a 2008 issue of the Mayo Clinic Proceedings successfully treated a 33-year old woman with pagophagia following complications with gastric bypass surgery:
“The patient received red blood cells, iron sucrose, and levofloxacin. On further questioning, the patient denied taking vitamin, mineral, or iron supplements since surgery and reported prolonged, heavy menstrual cycles. She consumed large amounts of ice daily for several months. The patient’s husband frequently observed her in the middle of the night with her head in the freezer eating the frost off the icemaker. The patient admitted to awakening several times nightly for months with an uncontrollable compulsion to eat the frost on the icemaker. This craving resolved after transfusion and iron administration”
However, if the condition is psychologically or culturally based, iron and vitamin supplements are unlikely to work, and other psychological treatments (such as cognitive-behavioural therapy) are likely to be employed.
