On Heads, sleeping beauty gets asked once. On Tails, she gets asked twice. If I walk into the room and see her being asked, it's a better bet that the coin landed tails. If this experiment is repeated many times, "Tails" will be the right answer twice as often. You can try this with a friend. As someone pointed out later on in the page, you just answer the first question freely and if it's tails are required to answer the second question the same way as you did the first. Or just answer heads every time--no memory wiping required. If it's really 50/50 then answering heads should get you your answer. Because the interviewer asks questions in an unbalanced manner, the interviewee actually gets more information just by being asked.
