"Yes or No" is a reasoning variety show that reveals the truth behind strange stories through a simple question-and-answer format. It breaks away from the complicated setups of traditional mystery programs, focusing on straightforward reasoning to uncover each story’s truth. Each episode features five guests—four detectives and one client. The client briefly reenacts the story of the episode, while the four detectives search for the truth by asking questions that can only be answered with “yes” or “no.” The show centers on the process of logical deduction, allowing the guests to get closer to the truth through each exchange. With a runtime of about ten minutes per episode, it simplifies complex formats and brings reasoning to its most concise form.
