"In the 2013 post "Lizardman's Constant is 4%", Alexander coined the term "Lizardman's Constant", referring to the approximate percentage of responses to a poll, survey, or quiz that are not sincere. The post was responding to a Public Policy Polling statement that "four percent of Americans believe lizardmen are running the Earth", which Alexander attributed to people giving a polling company an answer they did not really believe to be true, out of carelessness, politeness, anger, or amusement.
Alexander suggested that polls should include a question with an absurd answer as one of the options, so anyone choosing that option could be weeded out as a troll."
I might propose an extended/obvious corollary. The public will vote for whatever makes things most interesting/amusing. Laughing Gnome NME poll / Boaty McBoatface etc.
