Information overload (aka information flood) is a term that is usually used in conjunction with various forms of
Computer-mediated communication such as
Electronic mail. It refers to the state of having too much information to
make a decision or remain informed about a topic. Large amounts of historical information to dig through, a high rate of new information being added, contradictions in available information, and a low
signal-to-noise ratio make it difficult to identify what information is relevant to the decision. The lack of a method for comparing and processing different kinds of information can also contribute to this effect. A recent article in the
New Scientist claimed that exposing individuals to an information overloaded environment resulted in lower
IQ scores than exposing individuals to
marijuana, although these results are contested. The same article also notes that a night
without sleep can be as debilitating as over-exposure to information. The term was coined in
1970 by
Alvin Toffler in his book
Future Shock.
