Subject: Reminder: HCI/UX-Related Logic Puzzle
I'm still desperate for responses to this logic puzzle (I want to compare the results to a different form of the same puzzle, that had 200,000 responses!).
So if you haven't done so already, please consider spending a few minutes trying to solve it. It's good for your brain :)
Please distribute widely. I will share the results and their implications for HCI and User Experience.

1. Each block has one colored face that is either red or blue and the others are neither (they're natural grain wood or black or something)
2. Each block has a red face, there's another face that is blue, & the others are neither
3. Each face of block B is either red or blue
Maybe none of those really matter. My friend Andrew did this & his answer was different from mine.
I originally said I'd have to know the color of block B. I wonder what kind of faulty logic I have for saying that.
Andrews reasoning was that "the red-or-blue color for B is under A or over C to be non-visible, but it has to be either red or blue, no? So it's either top-down red-red-blue or red-blue-blue," either of which results in a red directly over a blue, making the answer "yes".
I wasn't sure it had to be either red or blue. Do you think that is assumed?
To me it was more like "I have three citrus fruits in a row, lemon on top, lime on the bottom, is the middle one a lime or a lemon?" It doesn't SAY there might be oranges or strawberries, but I said I couldn't rule the possibility out until I knew if the middle fruit was yellow or green.
I must say, even talking through all this illustrates a LOT to me about how I think.
