Good point.
“Flip this coin twice. If both flips agree, answer truthfully. If they're different, then answer ‘Yes’ if the 2nd flip was heads, ‘No’ if it was tails.”
“Flip this coin twice. If both flips agree, answer truthfully. If they're different, then answer ‘Yes’ if the 2nd flip was heads, ‘No’ if it was tails.”
I wrote the example thinking that people were filling in the survey in private (sort of like you, probably, do when voting).
Anyway, you get the concept :)

"You have a coin. Before flipping it, decide which flips you will count. Now flip it sixteen times, only paying attention to the nth and mth flips. If n and m agree, then answer truthfully, otherwise answer according to m's result, in a manner that you personally pre-designated"
:) That's when the survey-taker looks at you cross-eyed and just lies on the question.
