metalevels

Metalevels refer to hierarchical layers of analysis, reasoning, or control that operate on the level below them. In this sense, the object level describes phenomena or tasks directly, while the metalevel governs how those phenomena are studied, modeled, or managed. The distinction helps distinguish what is being done from how it is decided or organized to be done.

In philosophy and cognitive science, metalevel reasoning asks questions about the reasoning process itself, such as how to allocate attention, time, or computational resources, or which representations and models to use. This contrasts with direct task performance at the object level.

In artificial intelligence and computer science, metareasoning is the study of reasoning about the reasoning process. A metalevel component might decide when to stop an extensive search, how much to simulate, or whether additional data gathering is warranted, with the goal of improving overall efficiency and effectiveness.

In statistics and data analysis, metalevel or metamodeling often refers to models about other models or about the data-generating process. Hierarchical or Bayesian meta-models treat multiple layers of uncertainty, data, or models. Meta-analysis is a related concept that synthesizes results across multiple studies, effectively analyzing analyses.

In logic, metalanguage refers to the language used to discuss another language (the object language). Statements about truth, proof, or interpretation are made at the metalevel, separate from the statements within the language being discussed.

The term metalevels is context-dependent and can carry varying precise meanings across disciplines, but it generally denotes a higher-level viewpoint that governs, analyzes, or controls the level of primary activity below. See also: meta-, metareasoning, metalanguage, hierarchical modeling.
