tossines

Tossines is a hypothetical term used in anthropology and decision theory to describe a set of ritualized, randomizing practices that groups use to make collective decisions. The concept is often employed in theoretical discussions and speculative fiction to explore how randomness can facilitate consensus and reduce bias in group choice.

A tossine ritual typically involves producing a random outcome through a physical mechanism or a deterministic procedure designed to approximate randomness. Common methods include coin flips, dice, seeds, or balloting procedures with prearranged rules. The process emphasizes equal participation, transparency of the method, and a presumption that no single participant can unilaterally determine the result. Outcomes are usually treated as binding within the context of the decision, though the ritual may be revisited if new information arises.

Origins and usage of the term are informal, and tossines are mainly used as a thought-experiment device rather than a widely observed practice. In academic writing, tossines are discussed to examine questions of legitimacy, fairness, and the limits of voluntariness in decision-making. In fiction and scenario planning, they function as plot devices to illustrate how communities cope with uncertainty and power dynamics.

Variants of tossine practices may differ in the rules for initiating the ritual, the number of participants, and the aggregation method (single trial vs. repeated rounds). The core idea is to harness randomness as a democratic or legitimizing mechanism in collective choice.
