Grammaticality is determined by linguistic rules while acceptability is determined by native speaker judgment.

Is it true that Grammaticality is determined by linguistic rules while acceptability is determined by native speaker judgment?

Yes. While some linguistic frameworks and datasets maintain a clear distinction between formal grammaticality and native-speaker acceptability, cognitive and experimental studies demonstrate that acceptability judgments are heavily influenced by probabilistic, lexical, and processing factors, complicating the strict dichotomy between the two concepts.
