AI Coherence Score Without Logic in IELTS Writing

Direct answer

Many AI tools score Coherence & Cohesion by counting connectors and paragraph breaks, not whether each sentence follows from the last. An essay can earn AI praise for Moreover and In conclusion while jumping from claim to unrelated example. Examiners read argument chains: position → reason → evidence → link. When AI CC is 7 but TR is 6, you may have cosmetic cohesion without logic, a common inflation trap before exam day.

Surface cohesion vs logical progression

Surface Linking words, paragraph length, topic-looking sentences

Logic Each idea supports the thesis; no orphan examples

Examiner CC Band 7 needs clear progression throughout

Patterns AI over-rewards

Pattern	AI may see	Examiner sees
Connector stacking	High CC	Mechanical jumps
Template body	Clear structure	Thin TR, list not argument
Paraphrased intro	Cohesive opening	No new development
