There are 6 F's in the sentence "FINISHED FILES ARE THE RE- SULT OF YEARS OF SCIENTIF- IC STUDY COMBINED WITH THE EXPERIENCE OF YEARS". Spotting 3 F's indicates average intelligence, 4 above average, 5 means you can look down on most people, and spotting all 6 means you are a genius. Many people overlook the F's in "OF" because the brain sees them as V's instead.
