Math question supposed to reveal if someone is autistic

Post Reply New Topic

"A bat and a ball cost $1.10 in total. The bat costs $1 more than the ball. How much does the ball cost?"

A 2022 study found that those who were autistic were more likely to answer the question correctly. But to me it seems that anyone with a normal or average level of logical intelligence will give the correct answear.

Harvard-backed math question that reveals if someone could be autistic

Utter BS. I don't know if there's evidence that autistic people are more likely to be good at math (although based on people I know I'd guess yes), but obviously plenty of nonautistic people are good at math and plenty of autistic people are bad at math. Not to mention that question is fairly simple, it doesn't even say much about a person's math ability. It couldn't reveal anything about autism.

I am glad you included "supposed to" in the title. One study is one study, and that's all. Scientifically meaningless.

(Will all WP members who didn't solve the problem correctly now please change their profile and declare themselves neurotypical today. If this is not done by midnight they will turn into pumpkins).

Mathematical ability is highly heritable, and there are an abundance of studies on that topic; this is true for both neurotypicals and the AS population.

I have asd and dyscalculia, but I thought the ball can't be ten cents because most people would think that, so it must be wrong.

Do both disabilities cancel each other out, or what?

I got it right but it took me a while.

Like, yeah -- the bat can't be 1$ more than the ball if the ball is 10¢ and then it adds up to a 1.10$; that will be false -- that will add up to 1.20$ instead because the if the ball is 1$ more expensive, the bat would be 1.10$.

So the ball had to be less than 10¢ to add up to a bat that supposedly is 1$ more expensive than the ball if it had to add up to a 1.10$...


Yes, mine is a convoluted mess.
I don't have a greater than average mathematical ability.

Only a few inclinations over it like my bias towards geometry and logic.

And my reading comprehension is average at best and to compensate, I had to recheck and add more reasoning.

I'll work this out in pennies.

110 = (100 + x) +x

110 = 100 + 2x

110 - 100 = 2x

10 = 2x

5 = x

From the linked article. I'm not sure everyone read the article before commenting.
"If a person takes the time to think through the question and answers it correctly, it reveals that they're using their ability to think logically to fully understand the mathematical components.

This could put them on the spectrum because those with autism are neurologically built to think this way. Luraschi said that answering the question correctly 'can be indicative of a certain type of thinking style.'

Although this test cannot replace a clinical diagnosis, it can shed light on your thinking style.

A 2022 study found that those who were autistic and relied on the slower, logical and intuitive way of thinking were more likely to answer the question correctly."

I couldn't figure it out. At least not right off the top of my head. If I had written it out I think I would have, but I saw other people's answers first.

I got it wrong at first, so guess I must be a NT whoo hooo!! !

That took about 15 seconds.

My first reaction, though, was disbelief that you can buy a bat and ball for $1.10.
