If you were around in the 80's, you had a Rubik's Cube puzzle. I hated those things and always resorted to pulling the stickers off to win in frustration. Some students from Swinburne University of Technology created a robot that can solve the puzzle in 10.69 seconds. That under 11-second time includes time for scanning the faces of the cube and having the algorithm process the scans to solve the cube. link

You can ask the same things to the same people worded slightly different ways, and still get rather different results. For example, changing a question from asking did humans develop other animals to did animals and plants develop from other species can give a large difference, or explicitly including God in a question about a process will change the results compared to asking about the same thing without naming God.
People are kind of fickle when it comes to asking questions, even without all of the religious and political baggage that comes up in such surveys. A project researching how to teach basic physics once found, for basic homework questions, asking a person a question, then asking them "What answer would a smart student give?" caused some people to change their answer...
