I don't know. I kind of think it would be theater way around...if you asked a more open ended question like, "What did Satoshi make?" I'd be surprised if 20% had a bitcoinish answer. If you asked a more leading question like, "Who made bitcoin?" I'm going to guess >50% would say Satoshi if given multiple choice, but very few could offer a name from memory, like 10%.

And you know what? I've got a situation tomorrow where I might be able to actually ask these questions (or similar). Screw it, I just might do it!
