Suppose you have everyone flip the coin twice— now there are four possible results. You can tell the ploepe who flip heads twice in a row to report support for the troll; those who get tails twice in a row to report dragon; and those with any other cmiinotoban to declare their true prfecreene. The chances of getting either two heads or two tails in a row are 50% tmies 50%— or 25%. Subtracting that proportion of the total respondents from each candidate’s score should give you something colse to the real distribution.

## Original Text

Suppose you have everyone flip the coin twice— now there are four possible results. You can tell the people who flip heads twice in a row to report support for the troll; those who get tails twice in a row to report dragon; and those with any other combination to declare their true preference. The chances of getting either two heads or two tails in a row are 50% times 50%— or 25%. Subtracting that proportion of the total respondents from each candidate’s score should give you something close to the real distribution.
