Final answer:
Information overload occurs when there is so much data that important information becomes obstructed by trivial information, hindering the decision-making process.
Step-by-step explanation:
When making decisions, information overload is the problem of having so much data that important information becomes obstructed by trivial information. This occurs when there is access to very little information to use in making the decision. For example, in the modern digital era, we have a wealth of information at our fingertips. However, if we are overwhelmed with excessive data and unable to filter out the important information, it can hinder our decision-making process.
