How many "F"s

Have you come across this one?

How many "F"s do you see in the following text.


FINISHED FILES ARE THE RE-
SULT OF YEARS OF SCIENTIF-
IC STUDY COMBINED WITH
THE EXPERIENCE OF YEARS.

I was absolutely convinced that there were only three.

There's no trickery!
I gather I'm a person of average intelligence!

Like me ,you probably didn't see the 4th one at first ,because it has a v sound ?

Four ?

If you've seen four, aren't you missing something - maybe ask a six year old?

He is only a welder, don't expect to much, go easy on him.

Finger puppets can be used to distract Mr Clegg from sad thingsEuropean finance ministers said the rescue package would prevent the deputy prime minister from staring out the window for hours or turning up to Parliament in his underpants with 'help me' scrawled across his chest in blackcurrant jam.

Under the plan each student in Britain will be paid £9000 a year to be Mr Clegg's best friend, with bonus payments for singing him to sleep or entertaining him with a puppet show.

It must be the smallest number of distinct isosceles right triangles that will tile an isosceles right triangle.

I think A.R. you'll need to 'unsober up' to see more.

When I did it myself I couldn't believe there were more than three.

What tricks does our brain play on us that we don't see them all?

It seems a really simple task, one six year olds might be able to see abd do because they aren't conditioned by lots of reading.

Interesting little experiment, but sadly I don't think being able to count to 6 qualifies me as a genius.
