Look at the text below and
count the number of "F"s you see.

Finished files are the re-
sult of years of scientif-
ic studies combined with
the experience of many
years of experts.

Some people see only four. Most see five. Some get six. Very few see seven,
which is the correct number. Really, go back & count again, slower this time.
We are not as observant as we think... Pick a card any card.
