Downor

Downor is a neologism that appears in informal discussions of decision theory and logic to denote a heuristic or operator that emphasizes choosing the lower-risk option among alternatives linked by a disjunctive relationship. The term blends the words down and or, signaling a downward or risk-averse reading of disjunctions.

Definition and variants

In its simplest reading, a downor rule selects the option with the smaller potential downside. In a probabilistic framing, a downor decision may be described as choosing the option whose worst-case loss is minimized, or whose outcome distribution has a more favorable lower tail. Some writers treat downor as a meta-rule for resolving choice when several options could be pursued but a single path must be chosen, effectively prioritizing risk containment over aggressive upside in uncertain scenarios. Because the term is informal, precise formulations vary across discussions.

Context and usage

Downor is not part of formal decision theory or mainstream statistical practice. It is primarily encountered in online forums, blog posts, and speculative writing about risk management, artificial intelligence alignment, and teaching examples meant to illustrate heuristics. As a result, there is no canonical definition or widely cited consensus on its mathematical properties. Critics often point out that risk-averse heuristics like downor can underperform in environments where upside is reliably valuable or where downside probabilities are misestimated.
