This is when people give too much credence to immediately available information. For example, if you read/heard about something in the news (limited information, and one point of view on it) you go around believing it, thinking you are informed.
What you didn’t give weight to was what you didn’t find out about it – other points of view, the full story, the time leading up to the event, etc. How could you, you didn’t have the information.
How often to do make up your mind or take action based on the readily available (limited, packaged) information easily at hand?
