I also agree with your comment. I did both questions as fast as I could and only got the first wrong and the second right. It reminded me of a brilliant Civil Engineering professor I once had who was showing us his notes on the projector (the kind with the light bulb and magnifying glass over head) and someone asked him if he could turn off the lights. The student meant the lights, as in the classroom lights so he could see the projection better. The professor turned off the projector instead :)

I saw a pound coin and a 10p coin (UK) and got the first one wrong, I saw a bar graph with a lot of doubling bars, and saw the long history of doubling and got the second one right. I saw the money by denomination, and not as a quantity perhaps. Interesting.

Ok, so I posed both questions to my wife, and she answered both correctly, only pausing about 2 to 3 seconds before answering both. She then said the questions are stupid and are too elementary. Maybe this study is not foolproof and is only there to make people like me feel better about not being able to answer simple math questions better :P

Basically, once again, I've learned that my wife is smarter than me and that these studies should be taken with a grain of salt.

P.S. She is not a math person nor is she a tech person.

Just a sec.. where are you seeing that?

Sorry, I was describing the visual images I get when solving problems like this, the article is pure text.

Hmmm. Interesting that you point that out. I think if we were presented with a math formula (symbols), we'd have aced it.

I think the reason why my wife did it so fast is because it was fed to her as text only - in fact, I just read it to her. She's a lawyer and she's much better at interpreting text than most people.
