Count every ' F' in the following text:
FINISHED FILES ARE THE RE
SULT OF YEARS OF SCIENTI
FIC STUDY COMBINED WITH

A is 7+4+8+5+8+8+3+8
B is 7+4+5+7+2+4+8+3+5
The reasoning behind is further down.
Incredible or what? Go back and look again!! Anyone who counts all the 'F's' on the first go is a genius. Three is normal, four is quite rare.
(If you got it right on the first attempt, please let me know. You're a genius!!)
The brain cannot process 'of'.
