The Information Overload Bias

The tendency to place too much attention on information, even when it's barely relevant.

Curiosity and confusion lead us into information binges. And, with Google continually beckoning and rewarding us, the info-gathering habit is harder to break than ever.

When you confront the brain with too much information, the quality of the decision tends to decline.
