    Reminds me of a trolley problem variant I saw once. It went roughly like this:

    A trolley is headed for Track A, where a single person is tied to the tracks. You can pull a lever and cause the trolley to switch to Track B, which enters a tunnel that you cannot see inside. Track B might have 3 people tied to the tracks, or it might be free of people. You can’t see which.

    Two hours ago, a perfect prediction machine inside the tunnel predicted whether you would pull the lever.

    • If it predicted that you would pull the lever (sending the trolley into the tunnel), then it tied 3 people to Track B, thus setting it up so pulling the lever would kill 3 people.
    • If it predicted that you would not pull the lever, then it ensured Track B is free of obstacles.

    The perfect prediction machine is guaranteed to have made the correct prediction. Do you pull the lever?
