What are these easy questions? Without looking at any other replies I can tell you with 100% accuracy that the ball costs 5 cents. That makes the bat cost 1.05$ and together they cost 1.10$.
The lotus question is also piss easy, the only possible error is the result of a pretty grave oversight. Maybe they should have polled people at a local rock concert since these might be inclined to think with their own head and not students from some ivy league indoctrination factory  |

The results of this study are 100% correct.
I did basically the same thing... I even got the lily pad one right without issue so I was like "whatever I'm totally not falling for this".
I did realize 10c was wrong pretty fast but it still took me like 30s to realize why... |

In a lake, there is a patch of lily pads. Every day, the patch doubles in size. If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half of the lake?
I must be a genius.. my first response .0000001 seconds after reading the question was 47 since every day it doubles in size so obviously its 48-1=47......... :/ I don't even understand how someone would get 24 although maybe thats the point of the thread but was too lazy to read it all... |

Dang it, considering the rule:
please answer as spontaneously as possible.
I ended up with an answer of 10 cents. Wait, if this study shows that more intelligent people are more prone to cognitive bias, and I got the wrong answer, could that imply that I'm actually really smart?
+ Show Spoiler +No. That would be a logical fallacy of affirming the consequent. |

can someone please explain these?
Bat + Ball = $1.10 (ok)
Bat = Ball + $1 (ok)
=> (Ball +1) + Ball = 1.10 (no..... ball + $1 = bat + ball) no where did it say if you buy 2 balls and add a dollar it equals $1.10
Ball + Ball = $.10 (now irrelevant)
2Ball = $.10 (now irrelevant)
Ball = $.05 (now irrelevant)
Ball = X Bat = X + 1.00 X+ (X + 1.00) = 1.10 2X = .10 (If you do not understand how I got here, then well... idk what to say) X = .05
my problem with this is; let's say we know the ball costs 10cents, using your formula to prove it.
If we know the ball costs 10 cents we have no unknown X for his equation. If we would tackle it using logic it would also make either the premise P1: Ball + Bat = 1.10 false or the premise P2: Bat + 1.00 = Ball false.
so you're saying the question is wrong not the price of the ball? Equations should work backwards
Isnt the question define X, with x + x + 1 = 1.1 Being the general statement Its still really hard to think anyone can be serious with 10 cents being the ball right. even if so that would make the bat 1.10 (being a dollar more) and the total 1.20(not the problem, your mixing it up) The bat was never defined in the original statement, so defining the bat is a byproduct of finding out X (the way it went through my mind anyways, how i shouted 5 cents)
I just think the answer can be either 5 or 10 cents. Using a mathematical equation doesn't prove every situation. The question is; What is the price if there is 1 dollar difference? (White still costing $1.10) If you can't use your equation to resolve if you know the answer, doesn't it make your formula incorrect?
The question was
A bat and ball cost a dollar and ten cents. The bat costs a dollar more than the ball. How much does the ball cost?
We break down the information we are given into two premises
P1: Cost[bat] + Cost[ball] = $1.10
P2: Cost[bat] = Cost[ball] + $1.00
Using this we set up an equation to find the cost of the ball.
X: cost of ball
Y: cost of bat
From premise P2
Y = X + $1.00
From premise P1
Y + X = $1.10
=>
X = $1.10 - Y
Replace Y with the deduced value of Y (from P2) above to get
X = $1.10 - (X + $1.00)
=>
X = $1.10 - X - $1.00
=>
X = $0.10 -X
=>
X + X = $0.10
=>
2*X = $.10
=>
X = $0.10 / 2
=>
X = $0.05
But I guess you want to argue that "math is stupid" or "there might be an undisclosed premise Px that alters the cost of the ball at any time!". Since you posts so far have been partly unintelligible I don't find it particulary interesting to continue this.

Yay, i got both questions right!
Ummmmmmm... so my opinion as of now is that this (i don't really know what it is...hypothesis?) is either wrong or flawed, or something other than completely correct.
Since I can't see anything other than the abstract, I HAVE NO IDEA what they did exactly... but i have a few questions/comments, so here they go.
How does someone (in this case, the investigator of the study) rate people's intelligence? IQ's aren't even unanimous in their ability to determine intelligence, or at least ALL kinds or areas of intelligence. Unndergraduates at Ivy League schools may or MAY NOT be highly intelligent. It's also possible that they work REALLY hard. Those are often the more successful anyways.
What exactly is the study suggesting? If I were a colleague of these guys, I would urge them to rephrase of lot of their sentences, but I'm not in that realm of academia, so maybe that's why it's hard to follow. What i mean is...
What is the bias they are talking about? Bias of how smart people are? Obviously we aren't talking racial/economical...maybe social? Is bias the right word for this, or is what they are trying to say is that the smarter you are, the more likely you gloss over minor mistakes?
What if the people who answered incorrectly aren't actually the smartest people taking this test? If Neil de Grasse Tyson took this, I bet he would answer right, as well as most mathematicians...
I guess what I'm saying, is I'm really doubtful that this study can conclude anything. It may be somewhere in between a "waste of time", and "needs many more studies to mean anything".
Education does not equal intelligence, although it can foster it. I'm pretty sure (just like ALMOST EVERYTHING) that there are genetic as well as learned components to intelligence. So obviously studying THINGS may increase how smart you are, but it shouldn't be confused with increasing how knowledgeable either.
My definition of intelligence would be the capability and rate one learns, comprehends, and extrapolates/applies information. IN OTHER WORDS, problem solving capability. It's range is from about a rock --> infinite (like a god, or Jane or something). Obviously both god and jane would not only get those answers right, but know a lot more about why questions like those are relevant to these questions. So are the people missing these further along the line than the ones who aren't? Maybe...probably not, though.
EDIT: Since i'm no longer attached to any university, I won't be able to view the article in depth, but maybe someone could answer, what is cognitive sophistication? Is that like my History professor who maintains a nice beard, wears tweed suits, talks slowly and sophisticated, with a pipe, and over utilizes long words? Or do they just mean smart? I sincerely hope it's not the latter.

Well clearly none of the degrees attached to their names were math degrees. Some people go their entire lives without advancing far beyond a middle school understanding of math, even if their other areas are exceptionally strong.
Now watch this cleverness:
A bat and ball cost a dollar and ten cents. The bat costs a dollar, more than the ball. How much does the ball cost?
Suddenly the ball costs 10 cents instead of 5 cents. ****ing commas man. How do they work.
Haha this is awesome, took me second to read the comma correctly ^_^

The ball costs 5 cents! My immediate though was that the ball was 10 cents but I had a feeling it just wasn't correct so I wanted to reevaluate, I don't like to make snap decisions. I'm not good on the spot haha.
This study actually doesn't surprise me as the more intellectual people are the more arrogant they seem to be in regards to their own intelligence and thus will answer questions like these quickly because 'It's so easy!".
I got the lilypad correct two but, yet again, my immediate thought was to blurt 24 DAYS then I immediately said "WAIT A MINTUE!" However I feel that by reading the OP people are going to be more likely to double check their answers in their head as they are expecting it to be a trick question, that's probably why I wasn't so quick to confirm my answers of 24 days or 10 cents. |

The question was
A bat and ball cost a dollar and ten cents. The bat costs a dollar more than the ball. How much does the ball cost?
Agree to disagree, duel me

Obviously the ball is five cents, which I'd be surprised to see anybody NOT answer, however if you have zero time to calculate the answer then I think most people would have 10 cents jump into their head as the cost of the ball.
I know when I read the question I thought "10c because...no it's 5 cents, duh". I can't see many people getting this wrong in a written test (because the calulation takes less time than writing "10c"), but I could see many people getting the answer wrong in a verbal test (where you just blurt out 10c, by the time the thought makes it to your lips you know it's wrong, but it's too late). |

| Trick questions are trick questions for a reason. Theres a pretty good chance a dumb person would get this question wrong too, its just taht smart people think they got the right answer by saying 10cents. |

Maybe, people didn't consider how those psychology students suck at math since they hadn't used it much (SAT maths lol). I'd assume they have to be good at (they are tested on) = i.e. they are tested on memorising and giving theoretical solutions to problems, just like a biology or maybe chemistry subject.
Somebody correct me if I'm wrong with my assumptions.
Try asking Engineering/Mathematics/IT students -- people who actually are tested on their logical thinking.
This study seems ridiculous for now.

Ahh good point. Those are trick questions for a reason. Why are they testing cognitive bias with trick questions? At least have some normal control questions or something.
