Answer to Quick Intelligence Test
FINISHED FILES ARE THE RESULT OF YEARS OF SCIENTIFIC STUDY COMBINED WITH THE EXPERIENCE OF YEARS.

Did you find 3 F's in this sentence?


Wrong, there are 6 F's in the sentence.

Read it again!
The brain cannot process the "F" in "OF."
Incredible or what?
Anyone who counts all 6 "F's" on the first go is a genius. Three is normal, four is quite rare.
