informal psychology study

Here's the information you are given:
1. All cards are red on one side and green on the other
2. The red side either has an A or a C written on it
3. The green side either has a 19 or 22 written on it.

There are 4 cards arranged so the sides you can see show A, C, 19, and 22. Which 2 cards would you flip to attempt to verify the rule that if there is an A on one side then there is a 22 on the other side?

edit: the color (red/green) is irrelevant.

I won't vote because I read this the other day in one of my texts. 😀

IF YOU HAVEN'T VOTED YET, DON'T KEEP READING!



Yeah, we just discussed it today in class, and I wanted to see if people were really that stupid 🙂.

If a decent number of people vote, I'll try the alcohol/coke version and see if people do better on that one 🙂.

Call me stupid, but I'd flip the "A" card over to see if it said 22, and the "22" card over to see if it said "A".

Is it that simple, or am I missing something?

I read about something like this before but I forgot the point of it. 😱

A and 19.

Edit: you have to see if 19 has an A on the other side or not.

Right. The fact that the 22 has an A or C on it doesn't help... you can only disprove the rule if the 19 has an A on it, or the A has a 19 on it.

so its not about getting the question right, it's about ruling out that the first card you might pick up might not not be the right one?

how does an A on the 19 disprove the rule? the rule is you have an A or C on one side, and 19 or 22 on the other... you just proved A is on one side...

Read my original post. The rule you want to verify is that an A on one side implies a 22 on the other side. It's a given that all cards have A or C on one side, and 19 or 22 on the other.

Never mind. Reading comprehension problem on my part.
