A psychological feeling of being overwhelmed by too much information, or simply the factual presence of an exponentially increasing amount of information itself.
Information overload might be framed in terms of Barry Schwartz's paradox of choice, in which too much choice leads to increased opportunity cost of information not attended to. The psychological effects include increased expectations of the value of the information, and regret over ignoring information.
Some coping strategies for dealing with information overload include increasing the specificity of one's information need, and satisificing instead of maximizing.
