@@AndyUwU1003他們是知道的,可以參考維基 「Prior to the show, a contestant is administered a polygraph exam and asked 100 questions (50 questions in season one)-many of which are asked again in front of the studio audience during the actual taping of the program. Without knowing the results of the polygraph, they are asked 21 of those same questions again on the program」 況且不知道題目又何來測謊結果呢?
