    Default IQ Test Accuracy

    I was at Barnes & Noble today and decided to try this Self-Scoring IQ Test designed by the Honorary International President of MENSA, Victor Serebriakoff. There are two tests comprised of verbal, mathematical and spacial questions. I didn't even bother to take the second test because the first one was so frustrating. It made me question how valid IQ testing really is. I thought I would solicit some feedback from the forum regarding a few of these conundrums.

    Mistake #1 In the Example below, the third missile is clearly incorrect. (3+2) x 2 = 10, not 12.



    Mistake #2 Here is a description of how this problem works:



    The piles of blocks shown are solid. Any block without support is shown as such. Each diagram represents a pile of identical blocks. Write a number beside each letter in the column to show how many other blocks touch the block indicated by each letter. A whole face must touch.

    We're looking at SA 33 here.



    For A, I count one face, which is the edge of E.
    For B, I count one face, which is the edge of B.
    For C, I count three faces, one broad side of D, the edge of C, and the edge of B.
    For D, I count two faces, one broad side of C, and the edge of D.
    For E, I count two faces, the edge of E and the edge of one that isn't labeled between A and B.

    According to the answers in the back of the book, however... (SA 33) A=2, B=2, C=3, D=3, E=3.



    Am I misunderstanding something here? The directions clearly state that a whole face must touch.

    Mistake #3 SA 35



    For A, I count one face, the broad side of B.
    For B, I count two faces, one broad side of A, and one broad side of an unidentified block.
    For C, I count two faces, the edge of C against D and one broad side of an unidentified block below it.
    For D, I count three faces, the edge of D against E, the edge of C, and the edge of an unidentified block.
    For E, I count one face, the edge of D.

    But according to the answers, A=4, B=4, C=5, D=4, E=2. Refer to the answer for SA 35 in the second image above.

    Mistake #4

    Here is a description of the problem.



    In SA 37, each of the three cubes have three images on them, Cubes 1 and 2 share a common image, the two dots. The directions state that the same design does not appear on more than one cube, however, if the first and second cube are the same, we see a total of five different images. The directions clearly say that each cube has two blank faces so how can you have a six-sided cube with five images and two blank faces?



    But according to the answers, the first and second cube are the same.



    Mistake #5

    SA 40 has five different cubes, four of which have three different images, and one of which has two images. There is a total of fourteen different images that we can see. None of the cubes can be the same because the directions state that each cube has two blank faces, therefore there must be five different cubes.



    Yet again the answer in the back of the book states that there are three cubes. How can that be?



    Mistake #6

    My issue with these questions is one of semantics. Both questions use the word turn, which suggests a rotation, but in the second image, they apparently mean to flip. The example in the first image is correct, if you turn it clockwise, you get the image that is underlined. In the second image, however, the answer in the example they give is A, which would be correct if you FLIPPED the image upside down. But if you turn it upside down (as in rotate it), it would look more like C, except with the circle in the bottom right-hand corner instead of the bottom left.

    Keep in mind that this test was designed by the "Honorary International President of MENSA." If there are this many inaccuracies in a practice test, how many errors are there in IQ tests that you pay to take and can't verify their reliability? Consequently, how accurate is the score that you receive?

    Haha, that's pretty appauling.





    There are many issues with IQ tests. But allow me to state one of them.

    The fact that doing many IQ tests, trains you and thus artificially inflates your IQ by knowing the patterns and problemtypes before hand. It won't truely test your IQ unless you are faced with a new problem you've never encountered before and find/understand the problem quickly upon seeing it. That's the only way you'd access the parts of your brain that are relevant, and not just your memory banks.

    To keep making relevant IQ tests, one has to come up with entirely different concepts to test peoples IQ's. And there is a limit to how much you can do that.


    IQ is not a good measure of objective intelligence.

    I have a hard time accepting the legitimacy of an intelligence quiz that isn't proofread.

    Your images don't work. Have you considered a different host like imgur?

    Until I see the images, can't comment.

    The entire concept of IQ is stupid imo. You can't just "measure" intelligence, it's not that simple. If the concept itself is flawed then what can you expect from some mere test? I don't care if they have MENSA labeled on them or whatever, for me MENSA is just one big joke that I can't take seriously, always has been that way to be honest.

    One would assume that all of them have been checked for errors. Problem is, when you take an official IQ test, you have no way to compare your answers to the supposed correct answers.

    I wonder if anyone else is having problems seeing them. Are you accessing the forum on a cell phone? It was a pain in the ass to upload them in the first place so I'm probably not gonna do that again.

    IQ tests aren't all encompassing, but they do measure some forms of intelligence, whether it's mathematical, verbal, spatial, etc.

    The problem with that is that they aren't accurate and many people have blind faith in them which is what leads to my negative opinion of them. The people for their blind faith and the tests for their inaccuracy.

    The practice test that I took had a lot of inaccuracies. I haven't paid to take an official IQ test, but now I'm reluctant to put too much stock in the results without being able to verify it myself.
