I've read of a technique where for self-reported statistics you mix in a non-pertinent question with a known probability, using Bayes to extract the original prior probability.
For example, instead of asking kids "do you smoke pot?" you ask that of 80% of people and the other 20% get "do you own a dog?"; the surveyor has no idea which question was asked but knows the overall population of dog owners.
Does this technique have a name that you know of and did you consider it?
