Interesting read and I like that you included people's comments as that is very useful in understanding what is happening during the test.
My only comment is that if you want to test if people can actually tell the difference between two options is to give them three samples, of which, two are identical. (I did not read the whole thread so I'd this was already mentioned, my aplologies.). The problem with pick A or B is you have a random 50% chance of getting it right. But when you have to say A=B or A=C or B=C, and then select the one that is different, then it is very difficult to generate a correct result through guessing. It is strange watching people adamantly claim that they can tell the difference between the three samples, but then they get it wrong of which of the two out of three are identical! Not a slam of what you did, but just a suggestion if you or someone else does a study in the future.
