Have you ever wondered if your mind is normal (i.e. average) or somehow different? Here are 3 lateral thinking puzzles. The answers are published below, but do not go immediately to read them! Think up your own answers first.

Tests

TEST 1

Here is the story of a young girl. At her mother’s funeral, she saw an unknown young man. He was charming, really the man of her dreams. She madly fell in love with him. After a couple of days, the young girl killed her own sister…

Question: What motive did she have to do it?

TEST 2

Take at most 10 seconds to do this test, otherwise, it will not work.

Find how many ‘f’s there are in the following text:

+ + + + + + + + + + + + + + + + + + + + + + + + + + +

FINISHED FILES ARE THE RE-

SULT OF YEARS OF SCIENTIF-

IC STUDY COMBINED WITH THE

EXPERIENCE OF YEARS

+ + + + + + + + + + + + + + + + + + + + + + + + + + +

TEST 3

Do the following reasoning exercise, answering the questions one by one, without going to the next question if you have not answered the previous yet.

It is not necessary to write your answers.

How much is:

15 + 6 =

3 + 56 =

89 + 2 =

12 + 53 =

75 + 26 =

25 + 52 =

63 + 32 =

Yes, these are a bit more difficult but the exercise is really worth doing, so be patient:

123 + 5 =

Now think of a tool and a color!

Answers

TEST 1

She hoped that the young man would appear again at the funeral.

Explanation: If you gave the correct answer, you probably think like a psychopath.

The test was developed and used by a famous American psychologist to determine whether a person has a murderous mentality. Several criminals who did the test correctly answered the question.

If you did not give the correct answer, it is good for you! If someone of your friends found it, keep away from him! 🙂

TEST 2

How many ‘f’s did you find? Three?

It is wrong, there are six!

If you don’t believe me, go above and count them again!

Explanation: The mind cannot process the ‘OFs’. Awesome huh?

Anyone who manages to find six ‘f’s is a genius, those who find four or five are really rare, three – are normal… Less than three – change your glasses! 🙂

TEST 3

Did you think of a “red hammer”?

It is the answer given by 98% of people who did this exercise.

If you thought of something else, then you probably are one of the 2% of the people whose mind and thinking are quite different.

Did you solve these lateral thinking puzzles?

    *0* I LOVED THIS ANNA !! THANKS *-*
    I would’ve also enjoyed reading the Science behind these exercises.
    Keep up the awesome work.

    1. Anna

      Thank you for your appreciation! I will try to find some info

    2. Cerxi

      There is no science behind the first one, it’s an urban legend, actually.

      The second one is because of a quirk of how our brains interpret the English language, after years of use, especially monosyllabic words; phonetically. To your brain, “of” is parsed as “uv”, and so doesn’t count as an F word

      As for the last one, it’s actually a bit misrepresented here: Nontrivial math problems actually make it HARDER. When the trick is done in person, the math problems are very simple, but the questioner demands rapidfire answers, to get the questionee used to answering without thinking too hard. The numbers themselves have nothing to do with it. The simple fact is, under pressure, the first colour people are likely to think of is red, and the first tool is a hammer.

  2. moobs

    blue screwdriver

    1. raymond

      Green pencil

    2. great minds

      i thought i was special by not saying red hammer and here you are doubling up on my blue screwdriver. creepy.

    3. Sharmaine

      Omg I said blue screwdriver too! I’m shaking right now lol.

      1. Anna

        I think I should add the blue screwdriver option to the “red hammer” since it’s so popular :mrgreen:

  3. Maggie

    So apparently I’m a psychopathic genius and part of the 2%… awesome.

  4. raymond

    No sociopath 2% and green pencil and genius.

  5. ggugu

    great sum

  6. Marii

    1.I just guessed he was with her sister or something..
    2. I found 4/6, and only caught the last ‘of’
    3.Blue spade…

  7. Seirryn

    got the serial killer one, although it’s just an urban legend. found all the f-s. thought of a purple wrench

    1. Ames

      I thought of a purple wrench too! haha

    2. Becca

      Yup. Purple wrench. Three for three, same here. Bizarre.

  8. Sargonarhes

    Ok, I answered the first one right.

    I only counted 5 f at first.

    and a thought of a grey hammer.

    A genius I am not, just some one that likes to walk their own path. And if the shape doesn’t fit I will make it fit.

  9. Kane

    in number 2.

    there were no “f”‘s…..only “F”‘s and there were 6

    haha

  10. Danny D

    The first one was interesting, could have been a number of things. The second on got me! I missed all of the “of’s”. I did not think of a red hammer on the third one though, I thought of a silver wrench.

  11. Elizabeth

    Thought the first one was cause the guy was with her sister

    found all F’s

    purple wrench

  12. Clayton

    I thought she had some sort of affair and he turned her into this killing machine… That, or she was some sort of wild territorial animal and her sister was a threat.

    I caught one of the of’s, but not all of them. And actually I answered that there were no “f’s.” They were all “F’s.”

    Lastly, I said yellow hammer instead of red.

    Someone tell me what this means about me!

  13. Casiquire

    Yellow gardening hoe…is there something wrong with me? Lol.

  14. allan

    brown hammer

  15. leria

    For those of you who got purple wrench…….are you right or left handed?

    1. Becca

      Ambidextrous.

  16. Kevin Sweeney

    Question 2 : 0 f’s; 6F’s

  17. Hellchylde

    For number three.. I didn’t do the math.. only saw the last question. and still said “red hammer”.. weird

  18. Eric

    The second question asked how many “f’s” as in lower case. I only saw upper case F’s so my answer was none

  19. James

    i thought of a blue hammer, but when they ask u that, u feel pressured and dont always give the right answer

  20. 7777

    i said yellow hammer so i guess im semi-special

  21. Mandalyne

    Blue saw lol

  22. Amy

    Got the first one right, but I did hear it a few years ago and didn’t get it right the first time. Got all 6 f’s. Thought of a green knife- as a former scout I always have a knife on me and green is my favorite color.

  23. Happy

    I could not answer the first. I heard of the second so I knew what to look for. I thought of a purple wrench.

  24. Justin

    Green Hammer and I found the six f’s probably because I had seen it before. no idea of the first question

  25. Emily

    #1 I said because the man was her sisters husband lol
    #2 I said 3
    #3 I said Blue Hammer

  26. Lauren

    What does it mean if my answer to the first question was that she aborted her father’s unborn child?

  27. Jailton Bastos

    Martelo? Eu pensei no vermelho,mas numa chave…O.O

  28. Libba

    pink hoe…. hm ._.

  29. Arilde

    I thought her sister like the same man.

    I found 4 F’s.

    I thought of a Red Shovel.

  30. sam

    I said
    1. because her sister had become a man and she was pissed that it wasn’t the man she could be with.. lol

    2. I found 6

    3. I said purple wrench.

    I’m so smart. s-m-r-t.

  31. JenK

    1= I assumed she was literally dreaming of him and her sister was the one dating him?

    2-6f’s

    3= Yellow Saw?

  32. ajofie

    1-pain of extreme loss, confusion, desire, and anger. There was probably an argument of sorts.

    2- 5 fs

    3- mauve screwdriver

  33. Tantalus

    the person that thought up the first question in order to see if people have the mind of a murderer is about as smart as a chocolate teapot and about as useful, lol

  34. patrig

    answer 1 : the girl found out her sister killed her mom
    answer 2: I went full blown retard and looked at the pluses x’s instead of the sentence
    answer 3 green wrench

  35. softvelveteen

    could not answer 1
    5 fs
    purple hammer

  36. Shubham

    1. Failed

    2. counted all six F

    3. Yellow Wrench

  37. Jo

    It said the girl “madly fell”. She was obviously crazy.

    Got stuck on the idea that I could make more “F”s out of the “E”s, but couldn’t count them all in 10 seconds.

    Wrench of Green

  38. martin

    1 I thought the unknown boy was the priest presiding over the funeral
    2 6f’s, but have seen that before
    3 red screwdriver

  39. Aaron

    Not that it matters, but for posterity sake:
    1. She loved her sister’s new husband (come to think of it, why wasn’t she at the wedding?)
    2. 6 fs, but my mind glanced over two ofs before catching the mistake
    3. blue crowbar >.<

  40. Lucas

    1. Sister was dating the boy so she killed the sister?
    2. 5 f’s
    3. Purple Drill press

  41. jamie

    – i’m a psychopath :'(
    -found 5 of the f’s… so rare but not genius
    – strangely enough i thought of a pink spanner… hmmm
    i don’t even really like pink

  42. RTKean

    1]I thought she discovered that her sister hired the man to kill her mother and he was there to follow up by killing all the other heirs, of which. she was one. By Killing the sister the man would no longer have a purpose to kill thus saving herself.

  43. RTKean

    Sorry didn’t finish comment

    2] I got 6, I’m no genius, but I am alert.
    3] I thought of a orange hammer, so, orange sort of fits, i guess I paint things and put orange survey ribbon on items so as not to lose them. Logical.

  44. RTKean

    Sorry didn’t finish comment, it keeps feeding me back
