Can you count? Are you sure?

If you’ve ever gone through some form of continuous improvement training you may have done this little experiment.

But in case you haven’t, I’d like to challenge you to count the number of times the letter “F” (upper or lower case) is used in the following paragraph.

Post your guess, I mean answer, in comments section.  Ready?  Go!

The necessity of training farm hands for first class farms in the fatherly handling of farm live stock is foremost in the eyes of farm owners. Since the forefathers of the farm owners trained the farm hands for first class farms in the fatherly handling of farm livestock, the farm owners feel they should carry on with the family tradition of training farm hands of first class farmers in the fatherly handling of farm live stock because they believe it is the basis of good fundamental farm management.

    I got 27 the first time and 29 the second time so let’s call it 28! What do I win if I’m right?

    I got 35, But reading the post some says 36, so I need to count every line again and count F’s by line. And finally I found the F’s missing.
    36 is my number.
    Good excersice. If we can’t count properly, imagine when we ask the people in the shopfoor they pay attention and found the failing parts!!

    I got 36. I think some of the people who got 35 may be missing one of the “of’s” or the second “f” in “forefathers”. Nice exercise!

    By the way, this exercise is often used to demonstrate measurement system variation in Six Sigma training.

    The question is ambiguous. The “next paragraph” could refer to the one about farm hands or this one:

    “Post your guess, I mean answer, in comments section. Ready? Go!”

    In case the latter, the correct answer is zero.

    I’m with Jon on the question being ambiguous. If based on the paragraph in italics, 36. Used standard work tool of “search” and letter “f,” which highlighted each one, one at a time. I did this before and never came close to the right amount, which is 0 or 36 or ?? Great thinking exercise.

    0 or 36, depending on the actual next paragraph, or the inferred paragraph.

    We used to do something similar during Kaizen training, and the trick is not to read the words, either count backwards or turn the paragraph upside down.

    Or, may be you can copy the whole content into an excel workbook. Suppose you paste it in cell A1.
    Now paste this into any cell:
    =LEN(TRIM(SUBSTITUTE(SUBSTITUTE(A1,” “,”`”),”f”,” “)))-LEN(SUBSTITUTE(TRIM(SUBSTITUTE(SUBSTITUTE(A1,” “,”`”),”f”,” “)),” “,””))

    This will give you the result as 36 !

    Ron,

    I have worked in various industries, in various quality roles, i.e. Quality Engineer to Quality Manager. During that time, we have had to find a way to proof materials that people read. The best and most accurate way we have found is to actually, read the test backwards. Start at the last word and go backwards word by word. The reason for this is the human brain “fills in” words for us. Not sure if you have ever seen the paragraph written with only first and last letter of certain words and the letters in-between mixed up, but people are still able to read that paragraph normally, and understand the context. We read backwards as the brain then does not “fill in” the missing letters since it is not used to reading in this matter. It allowed us to catch mistakes, quickly and easily and not require someone manually typing it into another tool to do the work. I hope this helps if anyone else is doing this type of work, as this is a quick solution. Suggest using a piece of paper to help people move backwards in the paragraph as well instead of letting natural habits take over and “read” normally.

    Thanks,

    Sean

    I get 36. I copied & pasted the paragraph into MS Word & used the ‘find’ function (searched for ‘f’). Quick & easy.

    36. My eyes are now trained to recognize that “of” has an F in it. Just like they are trained to pick up when a word is doubled such as the “a bird in the bush” illusion.
