The Trolley Problem.
Now it’s your move.

A runaway trolley. Two tracks. No clean answer. Make the call, then see what AI predicted you’d do.

Choose what’s at stake.

Your decisions become the game.

  1. 01Face the problem.

    Read the scenario. Decide which track you’re willing to take.

  2. 02Lock it in.

    The AI seals its predictions before you commit. Compare notes when you’re done.

  3. 03Compare with friends.

    Invite a friend to face the same ten dilemmas, then see where your decisions split.
