“What information consumes is rather obvious:
it consumes the attention of its recipients.
Hence a wealth of information creates a
poverty of attention, and a need to allocate
that attention efficiently among the over-
abundance of information sources that might
consume it.”
— Herbert Simon

cues that lead the user in the right direction

7.
When information scent grows stronger from
page to page, users are confident that they’re
headed in the right direction. But when it’s
weak, they may be uncertain about what to
do, or even give up.
