I wonder if there is any literature on how conventions such as "calling it," double-dares, eany-meany-miny-moe and such have evolved? These are "games" that are used to facilitate decision-making and arbitrate disputes in childhood culture. Are such practices a training ground for adult interdependent decision-making? Do they capture or even inform adult notions of fairness and efficacy? For how long do people persist in using these practices? And, finally, where do they come from? I expect such conventions could have a very long history -- over the centuries.
