I never knew about these. The wiki article is actually pretty funny.
"the NORC reported that 73% of subjects in the study said that they could live indefinitely with eight sonic booms per day, while 25% said that they couldn't. About 3% of the population telephoned, sued, or wrote protest letters"
I think the juxtaposition of the survey results and the other means of displaying dissatisfaction is interesting... The results of our toothpaste survey showed 73% like our new, minty flavor, 25% were not favorably impressed and 3% had to get dentures.
