Information overload

Information overload has been documented throughout periods where advances in technology have increased a production of information. As early as the 3rd or 4th century BC, people regarded information overload with disapproval. Around this time, in Ecclesiastes 12:12, the passage revealed the writer's comment "of making books there is no end" and in the 1st century AD, Seneca the Elder commented, that "the abundance of books is distraction". In 1255, the Dominican Vincent of Beauvais, also commented on the flood of information: "the multitude of books, the shortness of time and the slipperiness of memory."[14] Similar complaints around the growth of books were also mentioned in China. There were also information enthusiasts. The Library of Alexandria was established around the 3rd century BCE or 1st century Rome, which introduced acts of preserving historical artifacts. Museums and libraries established universal grounds of preserving the past for the future, but much like books, libraries were only granted with limited access.

Renaissance humanists always had a desire to preserve their writings and observations,[14] but were only able to record ancient texts by hand because books were expensive and only the privileged and educated could afford them. Humans experience an overload in information by excessively copying ancient manuscripts and replicating artifacts, creating libraries and museums that have remained in the present.[14] Around 1453 AD, Johannes Gutenberg invented the printing press and this marked another period of information proliferation. As a result of lowering production costs, generation of printed materials ranging from pamphlets, manuscripts to books were made available to the average person.

Following Gutenberg's invention, the introduction of mass printing began in Western Europe. Information overload was often experienced by the affluent, but the circulation of books were becoming rapidly printed and available at a lower cost, allowing the educated to purchase books. Information became recordable, by hand, and could be easily memorized for future storage and accessibility. This era marked a time where inventive methods were established to practice information accumulation. Aside from printing books and passage recording, encyclopedias and alphabetical indexes were introduced, enabling people to save and bookmark information for retrieval. These practices marked both present and future acts of information processing.

Swiss scientist Conrad Gessner commented on the increasing number of libraries and printed books,[14] and was most likely the first academic who discussed the consequences of information overload as he observed how "unmanageable" information came to be after the creation of the printing press.[18]

Blair notes that while scholars were elated with the number of books available to them, they also later experienced fatigue with the amount of excessive information that was readily available and overpopulated them. Scholars complained about the abundance of information for a variety of reasons, such as the diminishing quality of text as printers rushed to print manuscripts and the supply of new information being distracting and difficult to manage. Erasmus, one of the many recognized humanists of the 16th century asked, "Is there anywhere on earth exempt from these swarms of new books?".[19]

Many grew concerned with the rise of books in Europe, especially in England, France, and Germany. From 1750 to 1800, there was a 150% increase in the production of books. In 1795, German bookseller and publisher Johann Georg Heinzmann said "no nation printed as much as the Germans" and expressed concern about Germans reading ideas and no longer creating original thoughts and ideas.[20]

To combat information overload, scholars developed their own information records for easier and simply archival access and retrieval. Modern Europe compilers used paper and glue to cut specific notes and passages from a book and pasted them to a new sheet for storage. Carl Linnaeus developed paper slips, often called his botanical paper slips, from 1767 to 1773, to record his observations. Blair argues that these botanical paper slips gave birth to the "taxonomical system" that has endured to the present, influencing both the mass inventions of the index card and the library card catalog.[19]

In his book, The Information: A History, A Theory, A Flood, published in 2011, author James Gleick notes that engineers began taking note of the concept of information, quickly associated it in a technical sense: information was both quantifiable and measurable. He discusses how information theory was created to first bridge mathematics, engineering, and computing together, creating an information code between the fields. English speakers from Europe often equated "computer science" to "informatique, informatica, and Informatik".[21] This leads to the idea that all information can be saved and stored on computers, even if information experiences entropy. But at the same time, the term information, and its many definitions have changed.[5]

In the second half of the 20th century, advances in computer and information technology led to the creation of the Internet.

In the modern Information Age, information overload is experienced as distracting and unmanageable information such as email spam, email notifications, instant messages, Tweets and Facebook(Meta) updates in the context of the work environment.[22] Social media has resulted in "social information overload", which can occur on sites like Meta (previously Facebook), and technology is changing to serve our social culture.

In today's society, day-to-day activities increasingly involve the technological world where information technology exacerbates the number of interruptions that occur in the work environment.[23] Management may be even more disrupted in their decision making, and may result in more poor decisions. Thus, the PIECES framework mentions information overload as a potential problem in existing information systems.[24]

As the world moves into a new era of globalization, an increasing number of people connect to the internet to conduct their own research[25] and are given the ability to contribute to publicly accessible data. This has elevated the risk for the spread of misinformation.

In a 2018 literature review, Roetzel indicates that information overload can be seen as a virus—spreading through (social) media and news networks.[11]

E-mail remains a major source of information overload, as people struggle to keep up with the rate of incoming messages. As well as filtering out unsolicited commercial messages (spam), users also have to contend with the growing use of email attachments in the form of lengthy reports, presentations, and media files.[30]

A December 2007 New York Times blog post described E-mail as "a $650 billion drag on the economy",[31] and the New York Times reported in April 2008 that "e-mail has become the bane of some people's professional lives" due to information overload, yet "none of [the current wave of high-profile Internet startups focused on email] really eliminates the problem of e-mail overload because none helps us prepare replies".[32]

In January 2011, Eve Tahmincioglu, a writer for NBC News, wrote an article titled "It's Time to Deal With That Overflowing Inbox". Compiling statistics with commentary, she reported that there were 294 billion emails sent each day in 2010, up from 50 billion in 2009. Quoted in the article, workplace productivity expert Marsha Egan stated that people need to differentiate between working on e-mail and sorting through it. This meant that rather than responding to every email right away, users should delete unnecessary emails and sort the others into action or reference folders first. Egan then went on to say "We are more wired than ever before, and as a result need to be more mindful of managing email or it will end up managing us."[33]

The Daily Telegraph quoted Nicholas Carr, former executive editor of the Harvard Business Review and the author of The Shallows: What The Internet Is Doing To Our Brains, as saying that email exploits a basic human instinct to search for new information, causing people to become addicted to "mindlessly pressing levers in the hope of receiving a pellet of social or intellectual nourishment". His concern is shared by Eric Schmidt, chief executive of Google, who stated that "instantaneous devices" and the abundance of information people are exposed to through e-mail and other technology-based sources could be having an impact on the thought process, obstructing deep thinking, understanding, impeding the formation of memories and making learning more difficult. This condition of "cognitive overload" results in diminished information retaining ability and failing to connect remembrances to experiences stored in the long-term memory, leaving thoughts "thin and scattered".[34] This is also manifest in the education process.[35]

In addition to e-mail, the World Wide Web has provided access to billions of pages of information. In many offices, workers are given unrestricted access to the Web, allowing them to manage their own research. The use of search engines helps users to find information quickly. However, information published online may not always be reliable, due to the lack of authority-approval or a compulsory accuracy check before publication. Internet information lacks credibility as the Web's search engines do not have the abilities to filter and manage information and misinformation.[36] This results in people having to cross-check what they read before using it for decision-making, which takes up more time.

Viktor Mayer-Schönberger, author of Delete: The Virtue of Forgetting in the Digital Age, argues that everyone can be a "participant" on the Internet, where they are all senders and receivers of information.[37] On the Internet, trails of information are left behind, allowing other Internet participants to share and exchange information. Information becomes difficult to control on the Internet.

The BBC reports that "every day, the information we send and receive online – whether that's checking emails or searching the internet – amount to over 2.5 quintillion bytes of data."[38]

Social media are applications and websites with an online community where users create and share content with each other, and it adds to the problem of information overload because so many people have access to it.[39] It presents many different views and outlooks on subject matters so that one may have difficulty taking it all in and drawing a clear conclusion.[40] Information overload may not be the core reason for people's anxieties about the amount of information they receive in their daily lives. Instead, information overload can be considered situational. Social media users tend to feel less overloaded by information when using their personal profiles, rather than when their work institutions expect individuals to gather a mass of information. Most people see information through social media in their lives as an aid to help manage their day-to-day activities and not an overload.[41] Depending on what social media platform is being used, it may be easier or harder to stay up to date on posts from people. Facebook users who post and read more than others tend to be able to keep up. On the other hand, Twitter users who post and read a lot of tweets still feel like it is too much information (or none of it is interesting enough).[11] Another problem with social media is that many people create a living by creating content for either their own or someone else's platform, which can create for creators to publish an overload of content.

Decision makers performing complex tasks have little if any excess cognitive capacity. Narrowing one's attention as a result of the interruption is likely to result in the loss of information cues, some of which may be relevant to completing the task. Under these circumstances, performance is likely to deteriorate. As the number or intensity of the distractions/interruptions increases, the decision maker's cognitive capacity is exceeded, and performance deteriorates more severely. In addition to reducing the number of possible cues attended to, more severe distractions/interruptions may encourage decision-makers to use heuristics, take shortcuts, or opt for a satisficing decision, resulting in lower decision accuracy.

Some cognitive scientists and graphic designers have emphasized the distinction between raw information and information in a form that can be used in thinking. In this view, information overload may be better viewed as organization underload. That is, they suggest that the problem is not so much the volume of information but the fact that it cannot be discerned how to use it well in the raw or biased form it is presented. Authors who have taken this view include graphic artist and architect Richard Saul Wurman and statistician and cognitive scientist Edward Tufte. Wurman uses the term "information anxiety" to describe humanity's attitude toward the volume of information in general and their limitations in processing it.[54] Tufte primarily focuses on quantitative information and explores ways to organize large complex datasets visually to facilitate clear thinking. Tufte's writing is important in such fields as information design and visual literacy,[55] which deal with the visual communication of information. Tufte coined the term "chartjunk" to refer to useless, non-informative, or information-obscuring elements of quantitative information displays, such as the use of graphics to overemphasize the importance of certain pieces of data or information.[56]

In a study conducted by Soucek and Moser (2010),[57] they investigated what impact a training intervention on how to cope with information overload would have on employees. They found that the training intervention did have a positive impact on IO, especially on those who struggled with work impairment and media usage, and employees who had a higher amount of incoming emails.[58]

Recent research suggests that an "attention economy" of sorts will naturally emerge from information overload,[59] allowing Internet users greater control over their online experience with particular regard to communication mediums such as e-mail and instant messaging. This could involve some sort of cost being attached to e-mail messages. For example, managers charging a small fee for every e-mail received – e.g. $1.00 – which the sender must pay from their budget. The aim of such charging is to force the sender to consider the necessity of the interruption. However, such a suggestion undermines the entire basis of the popularity of e-mail, namely that e-mails are free of charge to send.

Economics often assumes that people are rational in that they have the knowledge of their preferences and an ability to look for the best possible ways to maximize their preferences. People are seen as selfish and focus on what pleases them. Looking at various parts on their own results in the negligence of the other parts that work alongside it that create the effect of IO. Lincoln suggests possible ways to look at IO in a more holistic approach by recognizing the many possible factors that play a role in IO and how they work together to achieve IO.[60]

It would be impossible for an individual to read all the academic papers published in a narrow speciality, even if they spent all their time reading. A response to this is the publishing of systematic reviews such as the Cochrane Reviews. Richard Smith argues that it would be impossible for a general practitioner to read all the literature relevant to every individual patient they consult with and suggests one solution would be an expert system for use of doctors while consulting.[61]
