Jack is looking at Anne, but Anne is looking at George. Jack is married, but George is not. Is a married person looking at an unmarried person?
A) Yes.
B) No.
C) Cannot be determined.
This is from this month’s Scientific American — article unfortunately costs money. It’s about “dysrationalia,” which is what happens when people with nominally high IQ’s end up thinking irrationally. A phenomenon I’m sure we’ve all encountered, especially in certain corners of the blogosphere.
And the answer is the first option. But over 80 percent of people choose the third option. Here’s the solution: the puzzle doesn’t say whether Anne is married or not, but she either is or she isn’t. If Anne is married, she’s looking at George, so the answer is “yes”; if she’s unmarried, Jack is looking at her, so the answer is still “yes.” The underlying reason why smart people get the wrong answer is (according to the article) that they simply don’t take the time to go carefully through all of the possibilities, instead taking the easiest inference. The patience required to go through all the possibilities doesn’t correlate very well with intelligence.
I thought C. I didn’t read all the posts, I’m too impatient. The reason for my choosing C was that we do not know where George is looking. He might be looking at his nails, himself, Jack. Hence we don’t have enough info to answer the question.
All of you are trying to arguing about “What I choose C”… Next time only say, oh shit! is really A? and don’t try to autosatisfy yourselves saying to you “Eh eh, I have a Scientific reason to choose C”. Next time, simple say, nice game bro.

#102, PeneErectus:
Well, I did choose A.
But I still think it’s an interesting question as to why many people chose C: It suggests some ideas about how people think.
You can learn something about a system from its failures, as well as from its successes…
But cant Anne still be in a LIVE-IN relationship… Consider all the options.. So its C
Nice, so, I’m smart =D xD
The answer is C). We do not know if Ann is a person. Therefore, we cannot determine the answer. To say A) is to make an assumption and therefore to be wrong.

Hi, Im Jack, I was not looking to Anne, I was looking to George, but I felt embarrased to recognise it at first… so I lied. Oh! The answer is still “YES”, it doesn’t change nothing….
