Can you predict people?

How a round works

1. You’re holding an amount of real NIM.
2. You choose how much to pass to the next stranger who plays. Keeping all of it is a real option.
3. Before you see anything, you guess what the average person does.
4. Then you find out: your choice, your guess, and what researchers found studying the same kind of decision.

The NIM is real, and it travels

What you pass on becomes the next person’s money to decide over. A chain moves from stranger to stranger, getting smaller each time, until what’s left is too small to divide again, and whoever’s holding it then is told the chain ends with them, and keeps it.

Three questions

Split runs solo, right now. Trust needs a second person, you hand everything to a stranger and it triples in their hands, then they decide what comes back to you. Ultimatum needs one too, you offer a share, they set the least they’ll accept before they’ve even seen your offer, and too low costs you both everything.

Each one is a real experiment behavioural scientists have run for decades. The difference is that here it’s your money, and you find out where you sit.
