[QUOTE=mr apple;36387154]Can they at least tell us why the ball is 5c?
Seems like a stupid question not backed up
"How much is 2 + 2?
The question is both obvious and wrong, it's 3."[/QUOTE]
Because if the bat is 1 dollar more, then it is $1.05. Then added with the 5 cent ball, it equals $1.10, which was the total mentioned in the question.

bat + ball = 1.10 and bat = ball + 1 implies ball + ball + 1 = 1.10 implies 2(ball) = .10 implies ball = .05. Then bat = ball + 1 implies bat = .05 + 1 = 1.05.

[QUOTE=Ray-The-Sun;36387147]The first question is really poorly worded. It leaves a lot of stuff vague; it says a dollar more, when what is really meant is [I]exactly[/I] a dollar more, for example.[/QUOTE]
How is it vague? It says 1 dollar, which means exactly one dollar. Same with with math problems that give you X=3, you don't go thinking "Yeah but is the X [B]actually[/B] 3?".

Took me almost 10 minutes to figure out the correct answer for the first question. I feel dumb.

Both two and three are more than one, are they not?

I must be pretty smart, because i have no fucking idea about the ball

The ball took me a few seconds to do it and I initially just thought that it was a dollar but it's pretty easy to think about twice.
The lily pad was so easy. If it's covering the whole lake and it doubles every day, it only takes one day for it to go from half, to fully covered if it's doubling. No one should struggle with that.
I don't think this means anyones dumb, or smart. Mental math shortcuts are useful but thinking about anything more than once should allow you to doubt yourself and ask the question down different paths.

[QUOTE=Jack Trades;36381949]I fucked up on the Ball and Bat question but I answered Lilypad question correctly, what does that make me?[/QUOTE]
You predicted that the 2nd answer would be a "trick the person into answering quickly" question after you learned your lesson from the first one.
The point was not whether you got it wrong when you read the next sentence, but what your brain first thinks to do.
In the vast majority of situations these questions the "shortcuts" your brain uses are helpful.
for instance:
Bob, Joe, and Sam are given 100 chocolate bars each
Bob ate half of his 20 chocolate bars and had 80 chocolate bars left.
Joe ate twice as many chocolate bars as Bob and had 60 chocolate bars left.
Sam ate twice as many chocolate bars as Joe.
What does Sam have?
"smart" people will first multiply by four as opposed to doubling the number twice, but the first method is prone to messups. The 2nd, safer method is slower and hence those who use that answer instead are less prone to messups.
Both methods will lead to the right answer but the first one will be faster in most cases.
The people who used the first method are "smart," because they answer fast but when given a trick question they are more likely to fuck up.
Cognitive bias can be ironed out by anyone by just taking the slow route to a question. Truly smart people will know when to use the first method and when to use the second method.
The problem is the only thing they are basing "smart" off of is speed.
Person A takes 5 seconds to answer 1+1 correctly
Person B takes 1 second to answer 1+1 correctly
Person C takes 2 seconds to answer 1+1 correctly
Which of them is the smartest?
The most logical answer is person B so we label that person as the smartest.
If you ask them different types of questions before labeling you'll get a different answer.
Person A got the first question in the article wrong because he's a dumb fuck
Person B got the first question in the article wrong because he answered quickly and didn't double check
Person C got the first question in the article right. At first, he found the same answer as B, but caught how it was wrong in the double check.
Now are totals are person A got 1 out of 2 right, person B got 1 out of 2 right, and person C got 2 out of 2 right.
Wasn't B supposed to be the smartest? It's now C according to our new data.
also, the answer to the first question in case you were wondering is [sp]Sam has diabetes[/sp]

"Here’s a simple arithmetic question: 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?
The vast majority of people respond quickly and confidently, insisting the ball costs ten cents. This answer is both obvious and wrong. (The correct answer is five cents for the ball and a dollar and five cents for the bat.)"
I'm bad at math and got it wrong
it either means I'm 'too smart' or slightly dumb

I got both of them wrong and still don't know the answers...
The first question was worded weird, at least for me. When I see "a dollar more" I assume that whatever the ball equals the bat is a dollar.

I got the first one wrong but after reading 2 words from the sentence afterwards my brain started functioning and I revisited the problem and got it right. Got the lilypad-thing right instantly. I feel so smurt now.

if someone were to ask me that I would pretty much know it was a trick question, and think about it a second time before I answered

For some reason, when told that it's a trick question I always get it wrong (I did the same thing the last time this topic came up)
It's as if my brain goes "Better not stuff this up!" then instantly walks into a (metaphorical) wall.

I can do maths too!
Lets say my IQ is x.
x = a
if a belongs to the interval [100,200] (lets be realistic) ;
then x = a ;
then log x = log a aswell ;
log 200 = log 20 + log 10 = log 2 + log 100 = 2.301 ;
log x = log 2 + log 100
to get rid of the log;
10^(log x) = 10^(log 2 + log 100)
x = 10^2.3~
x = 200
My IQ is 200!
Maths man, you can't prove me wrong.

I often don't even think about certain problems.
My best description would be "it pops" into my head.
It's extremely strong with writing styles and wording, "picturing" scenes and problems and human motives.

Yes log20+log10 =log 20 makes totally sense

Woops, small mistep, but it matters not!
See, the article is true, smart people screw up!

Sometimes, I get the answer to relatively long and difficult problem popping up in my head for no reason, I'd assume it's kinda normal.
Also I'm quite sure he was being sarcastic.

[QUOTE=Ray-The-Sun;36387791]Both two and three are more than one, are they not?[/QUOTE]
The article says "a dollar more", not "more than a dollar". I'm a bit worried about people who can't understand the basic arithmetic to solve the problem, even after explaining it to them, but I'm even more worried about people that get it wrong because they can't read.

This is why I always make stupid mistakes in exams that seem simple a shit when the teacher explains, I demand a handicap system like in golf.

Well, I guess smarter people are more proud of their thinking and therefore, will be more inclined to not accept mistakes they do.

Oh boy, an article can make a poorly worded trick question in order to confuse people into giving the wrong answer. Whee, such an achievement. Clearly this shows that there's no point to being intelligent if you can be confused.

How is any of those questions poorly worded, they make perfect sense?

[QUOTE=LarparNar;36402352]How is any of those questions poorly worded, they make perfect sense?[/QUOTE]
They're intended to be deceptive. I suppose 'poor' isn't the right word.

I'm so smart I still don't understand the answer
