Read the sentence below and count the F letters. Count them ONLY ONCE. Do not go back and count them again!
FINISHED FILES ARE THE RESULT
OF YEARS OF SCIENTIFIC
STUDY COMBINED WITH
THE EXPERIENCE OF MANY YEARS.
What is your answer?
Is it THREE?
Well..
There are six F in the sentence. There is no catch. Most people forget the "of"s. The human brain tends to see them as V instead of F. Furthermore, the word "of" is a very difficult thing to visualize. You know what a "file" is, you can imagine something "scientific", you can picture something that is "finished", but you just can't picture an "of".
So if you spotted four, five, or six, you beat the average..
