Digital hoarding
The increasing availability of digital materials coincides with increased opportunity for people to accumulate digital materials. Van Bennekom et al. introduced "digital hoarding" in scientific literature in 2015 after reading descriptions of it published on the internet by both patients and professionals. They define it as "the accumulation of digital files to the point of loss of perspective, which eventually results in stress and disorganisation." Since the publication of this case study, several attempts have been made to study digital hoarding. In each of these publications there are clear knowledge gaps identified citing the need of more research to better understand digital hoarding. Sweeten et al. conducted one of the first research projects in 2018 that focused on digital hoarding, examining characteristics and potential problems associated with digital hoarding. They identified five barriers to deleting digital data including: keeping data for the future/just in case, keeping data as evidence, lazy/time consuming, emotional attachment to data, not my server-not my problem. They also identified four problems associated with accumulating excessive amounts of data including: effects on productivity, effects on psychological wellbeing, cybersecurity issues, links with physical hoarding. Participants in this study were frequently surprised by how much data they accumulated yet still experienced difficulties when discussing discarding that information. This study of digital hoarding was limited by a small sample of participants and the absence of an agreed upon standardized scale to measure digital hoarding behavior. Vitale et al. published another early research project in 2018 investigating digital data perceptions among a small sample of individuals with diverse backgrounds. This research focused on what digital items individuals held onto for multiple years and the criteria used to determine why and how those digital items were considered worth saving. The researchers used hoarding and minimalism as two extremes to discuss the spectrum of tendencies uncovered during interviews as they found these tendencies required context for understanding and not fitted for binary categorization. In addition to bringing attention to hoarding tendencies, Vitale et al.'s research compared and contrasted these tendencies as they relate to identity construction. Dillon suggests within the spectrum Vitale et al. established with hoarding and minimalism as extremes at each end, most human engagement with digital and physical objects falls in between those two extremes. Published studies focused on digital hoarding include adult participants and no children. One researcher in search of ways to apply what is known about adult hoarding to identifying and treating hoarding behavior exhibited by children suggested further research into digital hoarding behavior among children. The limited studies focused on examining digital hoarding behavior identified the following influential factors as having significant impact on an individual's decision to accumulate digital material:




Researchers cite the following developments in technology as playing a role in enabling the increased accumulation of digital material: The focus of existing studies on digital hoarding are narrow in scope, typically focusing on determining what differences and similarities exist between people's reasons to accumulate digital material in a work setting vs private setting. This boundary between work vs personal information spaces is becoming increasingly difficult to sustain prompting some archivists to suggest work and personal information could merge into personal record keeping. Other limitations include small sample research groups and a lack of agreed upon metrics to fully measure the aspects of digital hoarding behavior. Digital clutter is the term often used to describe the resulting (digital) artifacts of digital hoarding, but it should not be understood as exclusively the result of hoarding. Digital clutter can be created as a side-effect of high occurrences of another user activity, such as the computer desktop icons created through frequent installation of applications. In such a case the clutter does not reflect the user's intent to hoard. Housekeeping is the term often used to refer to the activity by which digital clutter moves out of the 'clutter' designation, either by being thrown away, or by the recognition of its importance, thus no longer making it part of the 'clutter'. Diagraphephobia is the fear of deleting files or an extreme fear of losing your data. Gadget Hoarding is the excessive hoarding of electronic hardware including computers, cellphones, wires and cables, VCR and DVD players, audio equipment, routers, and tablets, sometimes suffered along with digital hoarding. Digital hoarding occurs in any electronic spaces where information is stored. These are common areas where digital clutter may exist:





A cluttered email inbox arises when a user does not have a system for archiving some messages and deleting others that are no longer wanted. Electronic documents can become clutter if a user does not delete extraneous files, or if the files are poorly organized (e.g. inconsistent folder structure, empty folders). Some social media platforms also provide opportunity for digital hoarding. On the social networking site Facebook, for example, one can accumulate a vast number of “friends” that may merely be acquaintances or lapsed contacts or even complete strangers. Groups and Pages can also contribute to clutter when users join and like new ones, respectively, without leaving or unfollowing those in which they are no longer interested. Digital hoarding stems from a variety of individual traits and habits, corporate conditions, and societal trends: Digital hoarding can lead to many problems: Many American documentary television series depict the struggles of compulsive hoarders, such as "Hoarding: Buried Alive" on TLC and "Hoarders" on A&E. These shows have popularized awareness of hoarding, showing the consequences of accumulating clutter. However, these programs usually focus on physical hoarding. The WPTV story of Fort Lauderdale, Florida, resident Larry Fisher is a notable exception. This program focused on digital hoarding, depicting Fisher's longstanding refusal to delete any digital content. Instead, Fisher purchased an additional computer every time he ran out of hard drive space. The BBC News story of Washington, D.C., resident Chris Yurista expresses a counterpoint to this perspective. The program portrayed Yurista as a "21st century minimalist" for living with hardly any physical assets, substituting digital goods wherever possible. Though digital hoarding is often given a negative connotation, some counter that it is not an unhealthy or detrimental practice. One argument states that a large amount of digital content is not a problem in itself; rather, the problem is content findability. The size of the World Wide Web illustrates this point: a vast amount of content is available, but search engines such as Google have mastered effective algorithms for instantaneous findability. Digital hoarding can also be logical for email correspondence. Businesses often use email as the primary form of communication, so deleting conversations and documents that seem unimportant could be problematic if they are needed later. Disk storage is increasingly abundant and inexpensive, so concern over the cost of digital hoarding is rarely necessary. In addition, digital hoarding is clearly more benign than physical hoarding, which is more visible and takes up physical space. Finally, on a subjective level, digital hoarding can hardly be viewed as problematic if the consumer simply does not feel burdened by their collection of digital data. From the few studies that have specifically examined digital hoarding, participants cite their reasoning for saving many digital files is due to the lack of physical space it takes up. Siddick et al. examined carbon and water footprints of data centers located in the United States noting a lack of transparency surrounding the role of data centers in handling data, obscuring the environmental implications of data centers from the public eye.
As a medical condition
Research indicates there may be correlation between individuals who exhibit physical and digital hoarding behaviors and acknowledges there is a lack of psychological literature on the subject. Several studies suggest the main influential factors of digital hoarding are related to issues reduced costs for storing data, individuals lacking time to curate accumulated data, the perceived lifespan of data and emotional attachment to digital assets. The studies conducted to examine digital hoarding are limited in scope as this is an emerging area of study. There is a lack of agreement among researchers about whether digital hoarding is a condition to be treated rather than a normal human activity.
