How countless Fs do you see?

There is a succinct puzzle that has actually been law the rounds for a when now, i m sorry asks a very straightforward question, namely how countless Fs do you view in the complying with sentence?


“Finished records are the result of years of scientific study merged with the endure of years.”

Give the a go now and also take note of her count. Nothing over-think it and don’t invest a many time ~ above it.

You are watching: How many f in the picture answer

Did you acquire an answer? your answer is correct.

What?!? How deserve to this be? Well, the question was “How many Fs do you see?” If you only saw two, then the is the correct answer.

Admittedly, that was a bit cheesy and also pedantic, so let’s modify the question and make the a bit more robust by asking

How plenty of Fs are there in the complying with sentence?

You more than likely answered three, yes? This is the price most civilization give. Or an ext accurately, this is the price most indigenous speakers give.

The answer

There space actually six instances that the letter ‘f’ in the sentence – go back and check.

If friend still just see three, then inspect out the three times the word ‘of’ appears, they have actually the letter ‘f’ together well. Possibly this representation is an ext helpful.

Finished files space the an outcome of year of scientific study an unified with the experience of years.”

Infuriating, isn’t it?

The traditional (incorrect) assessment

Most of the areas where you watch this riddle then draw the an easy conclusion that the an ext you see, the more intelligent girlfriend are. Wasn’t that a funny pattern-matching exercise.

This conclusion significantly misses the suggest of the exercise and, together we will certainly see, has actually nothing to carry out with intelligence, but an ext to perform with just how we procedure language.

The linguistic assessment

There room two components that will affect your answer.

Firstly, the inquiry itself (how plenty of fs carry out you see) was a tiny bit mean, together it misdirects you right into thinking that a letter ‘f’ has a difficult sound, choose ‘fail’, but not a soft sound favor ‘of’ (where is sounds much more like a ‘v’).

The very first two words in the sentence (finished files) reinforce this incorrect subconscious thinking.

When we review the check sentence, because the word ‘of’ no sound prefer it has actually an ‘f’ in it, us don’t count it.

The other point is that when we process language, we don’t provide the same importance to every word. We have tendency to skip the small words, such as ‘in’, ‘on’, ‘of’, ‘at’ etc. And also give many of our fist to the nouns and also verbs. In various other words, once we check out the test sentence, we don’t really review the three instances of words ‘of’ – we just blur past them.

These two points account for why indigenous speakers tend to view three, instead of six.

Native speakers?

I’ve especially mentioned indigenous speakers an ext than once and also there is a reason for this.

When you very first learn a brand-new language, every one of the words room unfamiliar and also all have actually equal importance. Together you get more familiar v the language, you begin to process the words in a an ext targeted way, for example, glossing end the small, familiar, words.

What this method is the if you provide this test to someone who doesn’t speak English, they will many likely gain the exactly answer of six because, for them, it really is a pattern-matching exercise.

The astonishing conclusion is the the much better you room at English, the much more likely you room to gain the wrong answer. This is not how tests are supposed to work.


This has implications for proofreading. As soon as I’m proofreading my own text, I admit to having a remote spot. I know what the text is claimed to say and also my brain does a an excellent job that auto-correcting. I view what is supposed to be there, instead of what really is there. For various other text, as soon as I’ve read it a couple of times, the same effect occurs (to a lesser extent).
