Brief Intelligence Test
A quick test of perception: Don't cheat!
Read this sentence:
FINISHED FILES ARE THE RE-
SULT OF YEARS OF SCIENTIF-
IC STUDY COMBINED WITH
THE EXPERIENCE OF YEARS.
Now count ALOUD the F's in that sentence.
Count them ONLY ONCE: do not go back and count them again.
There are six F's in the sentence.
There is no catch. Many people forget the "OF"'s. The human
brain tends to see them as V's and not F's.
Pretty weird, huh? It fools almost everybody
