One thing I dislike about IQ problems, is when it gets difficult enough a person can find any number of patterns to generate the shapes

For instance, flip the shape upside down and move any horizontal bar to the opposite side. You'll get another one of those shapes. However because they come in pairs, it doesn't help with the missing shape. Therefore there must be some pattern between more than 2 shapes at once.

>>9615359
2

>>9615359
Here's another pattern: take the bottom one and overlap the one above it.
1) two lines overlap that are connected to the center
keep them
2) two lines overlap which are not connected to the center
Remove them
3) move the horizontal line to the opposite side

You literally cannot argue I'm wrong, because this generates the top shape from the bottom two shapes. Based on this reasoning the answer should be 2 and you cannot argue I'm wrong, even if I am wrong, because one pattern is as justified as the next.

>>9615377
Explain your reasoning nigger.

>>9615359
Work from top to bottom. The top two of a column yield the bottom.
Perform an AND on the central "spokes" and perform an XOR on the perimeter.
The answer is 2.

>>9615388
I just noticed that you can also work from left to right by performing an XOR on the spokes and an AND on the perimeter also giving 2.

>>9615397
>>9615388
me got by noticing that 2 incorporated all the elements of the corresponding row/collumn

>>9615377
this

>>9615359
I don't know if this is logically valid, but if you combine the first shape in the first row with the second shape in the second row, and the second shape in the first row with the first shape in the second row, and of course the first shape in the third row with the second shape in the third row, you all get well fit together shapes like puzzle pieces. Do that with the last shapes in the first and second row and you'll either get 1 or 2 depending on the rules.

>>9615412
that's more or less how I thought of it but I was too much of a brainlet to see how the big shapes related to the smaller ones. Really the missing piece should have been the middle. Would have been the ultimate pleb filter. Its pretty easy and intuitive as is and IQ tests never ask you to state your reasoning.

where can I find a bunch of these? Like seriously, they don't just make books comprised of these? I want to know if I'm retarded or not.

Ravioli Ravioli, give me more Questiolis!

>>9615359
It's a simple overlap one. You do the inner lines horizontally and the outer lines vertically. So 2.

>>9615377
This. Pretty simple, just an add/cancel pattern.

>>9615541
Better explanation.
The pattern is left to right, the first two columns create the third column.
The spokes cancel when they overlap.
The rim cancel if they don't overlap.

>>9615359
2 is the only one I see a loose pattern in
The center lines alternate from top to bottom as you go left to right and then on the final panel of the row they are on both top and bottom
The right hand diagonal line (lines in the case of the final row if 2 is correct) is kept and everything else is taken away

>>9615359
left to right: whatever black was in upper left in the first one, dissapears in the second and reappears flipped on the lower left, on 3 it dissapears. Note there is nothing black on the third row in that places so nothing changes. middle upper line is not on the first, but is on 2 and 3. Middle lower line is on 1 and 3 but is not on 2. lower right corner stays the same.
Therefore anwser 2.

>>9615359
This is a really nice variation on the classical XOR-puzzles. XOR for horizontal/vertical lines, AND for diagonal lines.

thick lines. If it's in both it gets carried over to last one. Thin lines, if it's in both it gets cancelled, if it's in only one of the two it gets carried over. 2

>>9615380
that's basically the inversion of the correct pattern, and it leads you to the correct result
if you want to adopt a strong position, find an equally plausible pattern that leads you to an incorrect answer

>>9615542
what is your definition of spokes and rims here?

>>9615440
https://en.wikipedia.org/wiki/Raven%27s_Progressive_Matrices

>>9615372
You're totally right.
Actually one should demand some reasoning from the test takers. Any reasonable solution should be right.
I once went through a sample IQ test for the job interview of a friend, and one problem was the continuation of
BCDFGHJKL***
We got to the solution "vowels left out" - which is a simple description - so MNP could be missing. But the actual solution was "leave out any fourth letter" - therefore MNO was "correct".
You'll be punished for thinking out of the box in such tests.

>>9616028
How does XOR work here? Look at piece 1,1 and piece 1,2. If you consider diagonal line = 1 and no diagonal line = 0 then look at the 1,1's upper left corner, that is a 1 since there is a diaginal there, now look at 1,2's upper left corner there is no diagonal there so that is a 0.

1 XOR 0 = 1. But in 1,3 there is no diagonal in the upper level corner. So your reasoning seem to fail here.

>>9616053
The "AND" means the logical AND operation.

>>9616056
I see it now

>>9616061
Didn't realize before that the formulation might be misleading.

>>9616063
It's okay.

I generalized the rules to:

diagonal + 0 = diagonal
diagonal + diagonal = diagonal

line+0=line
line+line=0

>>9616065
where addition is obviously commutative here.

>>9615541 >>9615542
2

Vertical & Horizontal lines cancel when overlap, added when otherwise,

The Diagonal lines remain when overlap, erased when otherwise.

>>9615359
The right answer isn't in there.

It's solved from left to right.

Where the diagonal lines out of the first two symbols overlap, the diagonal line is shown in the third symbol. And where the horizontal/ vertical lines overlap are left out of the third symbol.

So the answer should be pic related.

>>9616065 >>9616087
Answer 2

It can be represented mathematically as

diagonals
1 * 0 = 0
0 * 1 = 0
0 * 0 = 0
1 * 1 = 1

horizontal and vertical lines
|1 - 0| = 1
|0 - 1| = 1
|0 - 0| = 0
|1 - 1| = 0

>>9616101
welp, yep its two. Not only did i fuck up by instantly assuming OP to be a faggot and taking out the correct answer, i also fucked up the drawing by forgetting the two diagonals.

>>9616105
That is a clean way to represent it.

>>9615359
Couldn't tell, but narrowed it down to 1/2. Diagonals persisting in rows.

>>9615359

>>9616046
on average, smarter people find the right answer
how isn't important

What do you think is the minimum IQ needed to answer this particular question? I’d say 110

>>9616044
shut up Bill Clinton

>>9616197

>>9615359
These 2 do not belong with the rest.

>>9616197
wtf are you on about. It's 2

>>9615359
2 ez pz

>>9616108
good that you noticed your own mistake.
you have redeemed yourself

>>9615380
It works but its useless cause it's against the rules of the test.

2, bit of a brainlet to explain properly, but I'll try:

Going from top to bottom, you look at the first two images to decide what the third image looks like:

If the center sticks match they remain the same, if not you remove them, if the border sticks match you remove them and you place a stick where they don't match.

Why do people say online IQ tests are unreliable? How do I get tested? How hard is the question in the OP?

>>9617454
center sticks: AND
border sticks: XOR

Easy, its number 2.

What is outside must repeat to appear

>>9617574
why /pol/? What the hell does /pol/ have to do with this?

>>9617465
Every IQ test is unreliable in my opinion. You can't assign an exact number to someone's intelligence, the best they do is give a good approximation. OP's question is as easy as they get

alright, enough of this child's play

>>9617684
I'm going with 1.

>>9617758
explain your reasoning, homosexual

1

a line inside a circle cuts a circle into pieces so I'm going to assume two lines inside a circle also cuts it into pieces.

>>9617684
some fag just made this to troll people I bet

>>9617606
lmao rekt

>>9617684
>atomic shape, hour glass, square

>>9615359
Is this really what typical IQ test questions look like? I've been too scared to take one because I don't want to find out that I am retarded.

>>9617799
*I don't want to confirm

>>9617684
dafuq. this looks pretty hard

>>9617765
It's kinda difficult explain, more of a feeling I get from looking at it.
Though, looking at just the third column, if you draw that line together so the crescents bisect where the line is going through them then you would have a -90 degree rotation of 1 and it could be contained within that square.
But that's not a very good explanation because it doesn't account for the other patterns.

>>9617684
1
count the contained spaces in each sequence
>4,2,1
>8,4,2
>3,2,? (coincidentally the index is also the answer to the series)
that's what I think

>>9618065
what is the significance of 1 contained space?

>>9618142
The significance doesn't matter to answer the question

>>9618167
then its not a very convincing answer

>>9618194
Interested in what you score on IQ tests looking for significance in test structures

Completing the patterns has led to good results for me

>>9617684
I really wish C3 didn't exist

1,2,3
4,5,6
7,8,9

If you combine section 1 with section 5, you end up with a criss-cross square. When you combine section 2 with section 4 you also end up with a criss-cross square. When you rotate and transform the rest of the sections. You will once again find a criss-cross square...
The answer is 6 the criss-cross square

Unfortunately. I do see a problem in my answer of 6.... The rotation and transforming I mentioned requires the overlapping of non bold lines.... I might be wrong.

>>9618227
Don't worry, getting it wrong the first time only results in a 10 point deduction in your IQ score.

>>9615359
I am going to go ahead and answer 2

>>9616046
>Every fourth letter is missing
>A, the first letter is missing

Probably better not to work for those retards anyway.

>>9617348
What are the rules?

>>9618214
>you combine section 4 and section 2 you get a criss cross square

wut?

>>9615359

again this bullshit
no one cares
there are 1000 answers and none of them make sense
your IQ doesn't mean anything
grow up tard

>>9615359
Diagonal lines are boolean AND.
Horz and verts are boolean XOR.

Perform this operation on the first and second of each line to get the third.

>>9619151
There's one answer and it makes so much sense there are a shit ton of ways to get to it. You are just stupid

>>9615372
I took such a test recently, I just listed all the possible answers

>>9619345
nah, he's right. iq is proven bogus.

>>9619399

110
6
Please bully

>>9617684
prepare for brainlet
its 1
because 1st line is 2 nonfucked shapes in a row then a fucked one
2nd line is 2 fucked up shapes and then 1 normal one
last line is two normal shapes so it has to be a fucked up one- thus illuminating 2,3,4 and 5
plus it has semi circles which follows the rule from the 1st line where the circles make a fucked up circle

>>9619837
Who is to say what a "fucked up" shape is?

>>9616197
3 cant make sense because all the diagonal lines are present and that never happens before.

>>9619839
You take a good, hard look at those fucked up shapes and tell me there's a god.

>>9615359
I don't see a pattern, I think you are a troll cunt.

>>9617606
What did he post?

Took an online test and got 117, so am I smart enough to not be considered a brainlet?

>>9619892
some bullshit about how using the word "faggot" is insensitive I would guess.

>>9619860
>hat over hoodie

I love going out like that

>>9615359
answer is 2, outside elements don't matter and internal lines are xor'd horizontally

>>9615397
I just ignored the topleft-most squares in the pic and noticed that both from left to right and from top to bottom it consisted of moving the line along the triangle which basically consists of a 60 degree rotation counterclockwise. Then i added the two results to get 2. Am i brainlet or ritard?

>>9620155
Not an actual rotation thats just the best way i could describe it

>>9615359
One of the possible patterns is 2
You do an AND on each skewed line from pic 1 and 2 to get 3
You do an XOR on each vertical and horizontal line

mid row is just a fluke, or maybe the 2 splits combine into a square, who knows.

>>9622898
That was my reasoning as well

>>9621420
raven's matrices yes, it's only a small part of a professional iq test. Though you can get into mensa if you're good at it. I got over 130 on a mensa one and only 117 on a general IQ test, mostly because of low processing speed, but still. My brain can recognize patterns fast, but takes longer implementing the information and storing it for later use
