Sometimes an experiment to see if you can go five minutes without eating the marshmallow is just an experiment to see if you can go five minutes without eating the marshmallow, and not a trick to see what happens if they give you three marshmallows after eating the first one.

Sometimes, but they have a habit of lying about the purpose.

Yes, this is what every very smart person who underperforms or behaves illogically in a study says. Well, actually, I didn't choose wrong, I was testing the experiment. I chose to eat the marshmallow because I wanted to force them to reveal what would happen next, and then they told me the experiment was over, exactly as I predicted. I win again.
