I came across this study on information overload recently and wanted to highlight a few points from it.
SOLVING THE INFORMATION OVERLOAD PROBLEM: THE
ROLE OF UNCONSCIOUS THOUGHT IN ENHANCING ONLINE
"This assumption implies that people who have made a good decision often experience a high level of satisfaction during and after the process. Thus, in this study it is reasonable for us to use satisfaction with the decision as our measure of decision quality."
"H1: When one is dealing with rich information, using unconscious thought results in better decision quality than using conscious thought."
"H2: When one is dealing with rich information, an increase in the total quality of the information leads to an increase in the quality of the decision."
"H3: When one is dealing with rich information, an increase of the quantity of the information results in a decrease in the quality of the decision."
"When the information supply exceeds the information processing capacity, an individual usually has difficulty in identifying the relevant information, becomes highly selective, ignores much of the information, and fails to reach a satisfying decision."
"H4b: When one is dealing with rich information using unconscious thought, the greater the quantity of information, the higher the quality of the decision."
