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.
Paper 4 explicitly distinguishes between grammatical status (well-formedness according to formalisms) and acceptability status (intuitive goodness determined by native speakers).
Paper 0 argues that acceptability judgments present serious problems for binary formal grammars because they are gradient and influenced by various factors, showing that grammaticality and acceptability cannot be neatly separated into distinct deterministic categories.

The analysis
Judged against the evidence record for claims of this kind.
Paper 6 suggests that phonological acceptability judgments reflect similarity, lexical, and sensorimotor factors rather than strict evaluation of formal rules or constraints alone.
