Your friend (let's call her Alex) is given an amount of money (say, €10), and is told she should share it with you. Alex can decide how much money you get, and how much she gets. Whatever she apportions to herself is hers to keep, on one condition: *you* have to agree to her proposal*.* In other words, Alex can propose any division of the money she likes, but the ultimate power lies in your hands: you can accept (and each of you gets your share) or decline (and both of you go home with nothing). What kind of split do you think Alex would suggest?\n", "\n", "According to classic economic theory, the only reasonable option is for Alex to propose the maximum share for herself (€9) and the minimum for you (€1). After all, you -- the responder -- would surely accept €1 as being better than nothing at all, so why would you decline her offer?\n", "\n", "When real people were asked to play this *Ultimatum Game* (Güth, Schmittberger & Schwarze, 1982)*,* however, economics around the world were shocked and astonished to discover that people are not actually all that rational. In fact, responders will often decline unfair offers, even if they, in economic terms, are only shooting themselves in the foot! The players in Alex's position -- the proposers -- also tend to be much nicer and tend to make proposals that are only *slightly* unfair." ] }, { "cell_type": "code", "execution_count": 2, "outputs": [ { "data": { "text/plain": "", "text/html": "

Shortly said, during an experiment the \"prepare\" script will be ran before the trial starts, and the \"run\" script will be ran during a trial (for more information see the [OpenSesame website](https://osdoc.cogsci.nl/3.3/manual/python/about/)).
