This is what I mean about people taking the test being preselected to agree with yudowsky: that argument only works if you've read the sequences and are on board with his theories. Anyone not in that group would be able to just type "no lol" without issue. I guess he could explain all the necessary background detail as part of the experiment. I still don't believe that would work on the "average person" though, or anyone outside a statistically tiny group.
I guess the answer is not to let the scientists guard the AI room.
