Try this test. It is pretty wild. 

Don't cheat. You will only cheat yourself.

It is a quick test. It is a lot of fun. And, I promise, there are no "tricks" to the test.

Read this sentence:
    
FINISHeD FILeS ARe THe Re-
SULT OF YeARS OF SCIeNTIF-
IC STUDY COMBINeD WITH
THe eXPeRIeNCe OF YeARS.

Now count the F's in that sentence. Count them only once, only once:   do not go back and count them again.

After you are done, scroll down to see the answer.

The answer is below.

Answer:    
There are six F's in the sentence.

The "average" person finds three.

There is no catch. Many people do not see the Fs in the word "OF". It has been argued that the human brain tends to see them as Vs and not Fs.
