The Iowa Gambling Task is a laboratory game that serves as the foundation for the scientific understanding of intuition.

On a computer screen, four stacks of cards are displayed to participants.They will be awarded a cash reward or a penalty each time they turn a card.Two of the decks typically offer substantial rewards but even greater penalties, resulting in a loss over many turns.

The safer option is the other two decks, which have even smaller penalties and rewards than the other decks.
