Information overload

Information overload (also known as infobesity, infoxication, or information anxiety) is the difficulty in understanding an issue and effectively making decisions when one has too much information (TMI) about that issue, and is generally associated with the excessive quantity of daily information. The term "information overload" was first used as early as 1962 by scholars in management and information studies, including in Bertram Gross' 1964 book The Managing of Organizations and was further popularized by Alvin Toffler in his bestselling 1970 book Future Shock. Speier et al. (1999) said that if input exceeds the processing capacity, information overload occurs, which is likely to reduce the quality of the decisions.

In a newer definition, Roetzel (2019) focuses on time and resources aspects. He states that when a decision-maker is given many sets of information, such as complexity, amount, and contradiction, the quality of its decision is decreased because of the individual's limitation of scarce resources to process all the information and optimally make the best decision.

The advent of modern information technology has been a primary driver of information overload on multiple fronts: in quantity produced, ease of dissemination, and breadth of the audience reached. Longstanding technological factors have been further intensified by the rise of social media including the attention economy, which facilitates attention theft. In the age of connective digital technologies, informatics, the Internet culture (or the digital culture), information overload is associated with over-exposure, excessive viewing of information, and input abundance of information and data.

Even though information overload is linked to digital cultures and technologies, Ann Blair notes that the term itself predates modern technologies, as indications of information overload were apparent when humans began collecting manuscripts, collecting, recording, and preserving information. One of the first social scientists to notice the negative effects of information overload was the sociologist Georg Simmel (1858–1918), who hypothesized that the overload of sensations in the modern urban world caused city dwellers to become jaded and interfered with their ability to react to new situations. The social psychologist Stanley Milgram (1933–1984) later used the concept of information overload to explain bystander behavior.

Psychologists have recognized for many years that humans have a limited capacity to store current information in memory. Psychologist George Armitage Miller was very influential in this regard, proposing that people can process about seven chunks of information at a time. Miller says that under overload conditions, people become confused and are likely to make poorer decisions based on the information they have received as opposed to making informed ones.

A quite early example of the term "information overload" can be found in an article by Jacob Jacoby, Donald Speller and Carol Kohn Berning, who conducted an experiment on 192 housewives which was said to confirm the hypothesis that more information about brands would lead to poorer decision making.

Long before that, the concept was introduced by Diderot, although it was not by the term "information overload":

As long as the centuries continue to unfold, the number of books will grow continually, and one can predict that a time will come when it will be almost as difficult to learn anything from books as from the direct study of the whole universe. It will be almost as convenient to search for some bit of truth concealed in nature as it will be to find it hidden away in an immense multitude of bound volumes.
