Tilgáta

Tilgáta is a term used in Icelandic to denote a tentative explanation or educated guess that can be tested through observation and experiment. In science, a tilgáta is a specific proposition that makes a numerical or observable prediction about the behavior of a system under defined conditions. A tilgáta should be testable and falsifiable, enabling empirical assessment and potential revision based on evidence.

Etymology: The word combines til-, meaning toward or for, with gáta, meaning guess or estimate, reflecting its function as a provisional, testable idea.

Formulation and use: Researchers formulate tilgátur to explain phenomena, to guide data collection, and to structure experiments. A tilgáta should be stated clearly enough to yield predictions that can be confirmed or disconfirmed by data. As evidence accumulates, tilgátur may be supported, refined, or rejected. In many cases, a well-supported tilgáta contributes to the development of a broader theory.

Relation to theory: Unlike a theory, which is a robust, well-substantiated explanation of many phenomena, a tilgáta is inherently provisional and subject to falsification. The process of testing tilgátur is a core part of the scientific method and applied research across disciplines, including natural and social sciences.

Example: For instance, a tilgáta may state that increasing temperature accelerates the rate of a chemical reaction, and experiments measure reaction rates at different temperatures to test the prediction.
