Hardest "IQ" Test in the World Hardest "IQ" Test in the World

I found this while looking into Marilyn vos Savant's background in this thread.

They say that only 1 in a million people can get 90% of them right, or 43 of 48 questions. That's what it takes to get in the Mega Society. Some other high IQ societies only require you to get 50% right, and you'd still be way above Mensa level. That's how hard it is.

A few of the questions:


VERBAL ANALOGIES
Write the word or prefix that best completes each analogy. For example, in the analogy MAN : WOMAN :: ANDRO- : ?, the best answer would be GYNO-.

1. STRIP : MÖBIUS :: BOTTLE : ?
10. PILLAR : OBELISK :: MONSTER : ?
22. LANGUAGE GAMES : LUDWIG :: PIANO CONCERTI FOR THE LEFT HAND : ?

...

SPATIAL PROBLEMS
The design to the right is made up of three squares of different sizes, lying one on top of another.

What is the minimum number of squares that would be sufficient to create each of the following patterns?

26.

27.

29. Suppose 27 identical cubes are glued together to form a cubical stack as illustrated to the right. If one of the small cubes is omitted, four distinct shapes are possible; one in which the omitted cube is at a corner of the stack, one in which it is at the middle of an edge of the stack, one in which it is at the middle of a side of the stack, and one in which it is at the core of the stack. If two of the small cubes are omitted rather than just one, how many distinct shapes are possible?

...

INTERPENETRATIONS

34.Three interpenetrating circles yield a maximum of seven pieces, not counting pieces that are further subdivided, as shown to the right. What is the maximum number of pieces, not further subdivided, that can be formed when three circles and two triangles all interpenetrate?


35. Suppose two right circular cones and one right circular cylinder mutually interpenetrate, with the base of each cone and both bases (i.e., both ends) of the cylinder sealed by precisely fitting flat circular surfaces. What is the maximum number of pieces (i.e., completely bounded volumes) that can thus be formed, considering only the surfaces of these three figures as boundaries and counting only pieces that are not further subdivided?

...

PROBABILITIES

37. Suppose you are truthfully told that ten marbles were inserted into a box, all of them identical except that their colors were determined by the toss of an unbiased coin. When heads came up, a white marble was inserted, and when tails came up, a black one. You reach into the box, draw out a marble, inspect its color, then return it to the box. You shake the box to mix the marbles randomly, and then reach in and again select a marble at random. If you inspect ten marbles in succession in this manner and all turn out to be white, what is the probability to the nearest whole percent that all ten marbles in the box are white?

...

Suppose there is an ant at each vertex of a triangle and the three ants simultaneously crawl along a side to the next vertex. The probability that no two ants will encounter one another is 2/8, since the only two cases in which no encounter occurs are when the ants all go left (clockwise) -- LLL -- or all go right (counterclockwise) -- RRR. In the six other cases -- RRL, RLR, RLL, LLR, LRL, and LRR -- there will be an encounter.

For the following five problems, imagine there is an ant at each vertex and that the ants all simultaneously crawl along an edge to the next vertex, each ant choosing its path randomly. What is the probability that no ant will encounter another, either en route or at the next vertex, for each of the following regular polyhedrons? (Express your answer as a reduced fraction; e.g., 2/8 = 1/4.)

38. A tetrahedron
39. A cube
40. An octahedron
41. A dodecahedron
42. An icosahedron


NUMBER SEQUENCES

Determine the value of ___ in each of the following sequences. For example, in the sequence
1 4 9 16 25 ___ 49 64, the value of ___ is 36.

43. 4/10 ___/100 168/1,000 1,229/10,000 9,592/100,000 78,498/1,000,000
44. 1 4 17 54 145 368 945 ___
...
48.

I think smart people might be more likely to know what a klein bottle is, because maybe they are more interested in those kind of things.
But that would definitely introduce some unwanted variance in the test result.

I am super thick, I did not even get the example until I looked up andro and gyno in wikipedia. However all these IQ tests need a time limit to be able to be used for IQ estimation. Given enough time many people would get some of the maths based ones.

a month

Since it is partly based on knowledge it is essentially flawed to measure intelligence, but might be decent for IQ.

wait, you can spend a month, unsupervised and they ask ****wad questions like the wittgenstein one that any downie with an internet connection can answer? It's a terrible question supervised, but just pointless unsupervised.

The rules say that online research is not allowed. Obviously this is unenforceable.

Regardless of all those flaws, they say this:
"The median score is 8 right (I.Q. = 135)."
That's out of 48. Distributions and other info is here:

Spoiler:

7 %

I calculated all possible Black-White combinations:
10 White: 1/1024
9 White/1 Black: 10/1024
...

For every Black-White combination I calculated the 10 times White probability.

For every Black-White combination I calculated the weighted probability.

Than I divided 10 White's weighted probability by the sum of all weighted probabilities.

Is this correct?

IQ was invented for use in children and those that used to be referred to as "mentally ******ed".

It really doesn't have a good strict meaning for a population of adults.

"Your IQ may be higher, but mine is thicker."

Don't want to be a party-pooper, but it may not be fair or ethical to discuss the answers to these questions here.

"5. DISCUSSION OF PROBLEMS. As the Titan Test may be used as an admissions test to several societies, please do not share answers in a public forum with anyone who has not tried this test already."


btw this test is considered old and other more difficult tests have been developed.

From my understanding of IQ, this test has tons of questions that make no sense. IQ has nothing to do with knowing facts or vocabulary.

What in the hell would #10 be? Terrapin?

Reasoning: Obelisk comes originally from the greek and is a kind of pillar. Terras appears to be the greek word for monster, and terrapin is the only word I can think of that might be based on it that is a sort of monster.

I guess I'm too dumb for this club if you need to get 43 right.

It does not appear to have been updated any time in the last 6 years and the last update to the main webpage appears to have been in 2006. I don't think it's unreasonable to think that the webpage has been abandoned.

Also, from the mega society webpage:

The explosion of the Internet since 1995 has made it extremely hard to keep test answers secret. Half of the Mega and Titan test answers are easily available on the Internet today.
This article was written in 2001. I don't think discussing them at this point is unethical. I doubt they actually use these tests anymore (if they're smart -- and they claim to be).

Half of these are based on very specific knowledge that is not related to iq at all. It may be a hard test assessing a very particular form of intelligence, but to call it an iq test is a big stretch.

I was about to find this thread interesting until I realized I wasn't going to get any of the word association answers right. Then I gave up and did the sad face

At least I can say that I'm more self-aware than most of the people that actually could answer that stuff without serious study/research. So, I got that going for me...

Those feel to me like crossword puzzle clues. There are multiple "OH THAT MUST BE IT" answers possible. I feel like my earlier example isn't one of those, and that I just didn't stumble on the right way to look at it.

The sequences are actually doable with a bunch of work, as are the various plays on spatial relations. The word ones basically require you to know what the hell they're thinking.

Like the 4: HAND::9:? could be either some sort of weird reference to something, or maybe it's like squid because a hand has 4 spaces between digits and a standard squid would have 9 spaces between it's legs + tentacles. Or a hand has 4 fingers (not counting thumbs), so we need something with 9 fingers. And it can'e be "Frodo" post-smeagol bite since 9 would be counting his thumbs too and we discounted thumbs from the first.

EDIT: I think there's a unit of measure called a hand, which may be 4 inches. What's 9 inches? PENIS.

My contention: I overthink them because I am apparently dumb and lack the requisite knowledge to see the intended reference.
