presumtioner

Presumtioner is a term used in some discussions to describe the collection of presumptions that underlie reasoning, argumentation, or decision-making. It is not a standard term in major legal, philosophical, or linguistic dictionaries, but it is encountered in niche writings and discussions about how people reason.

Etymology and scope: The word appears to be formed from the verb "presume" combined with the suffixes -tion and -er, to denote an entity that embodies presumption. Its meaning varies by author, but it generally refers to the set of assumptions adopted as baseline or default within a system.

In practice: A presumtioner can refer to either a person who operates under a given set of presumptions or to the systemic collection of those presumptions used to guide inference. This can apply to legal contexts (where legal presumptions shape outcomes until evidence counters them), scientific practice (where priors or default hypotheses serve as starting points), or everyday reasoning.

Relation to other terms: Presumtioner overlaps with but is not identical to presupposition, assumption, and presumption. Presumptions can be unwritten and automatic; presuppositions are background assumptions built into statements; priors are explicit starting beliefs in Bayesian analysis.

Critique and use: Relying on presumtioners can speed up decision-making but risks bias and error if they are incorrect or outdated. Transparency in listing and justifying presumptions improves clarity and allows testing and revision.
