Brain Teaser: Can you count?

By: SharpBrains

Quick! Count the num­ber of times that the let­ter F appears in the fol­low­ing sentence:

—

“Fin­ished files are the result of years of sci­en­tific study com­bined with the expe­ri­ence of years.”

—

How many did you find?

Answer:

How many letters F did you count? Three? Wrong, there are six! It is no joke! Read again:

         FINISHED FILES ARE THE

         RESULT OF YEARS OF SCIENTIFIC

         STUDY COMBINED WITH THE

         EXPERIENCE OF YEARS

Almost everyone guesses three. Why? It seems that the brain cannot correctly process the word "OF". The letter F usually makes the "f" sound, like in "fox". However, in the word "of", it makes a "v" sound. Somehow, your brain overlooks the word "of" as it scans for the sound of "f".
