Readability scores measure how difficult your text is to read. For academic writing, you actually WANT higher complexity — but not so high that your examiner struggles to follow your argument. The ideal range for thesis writing is grade level 14-18 (Flesch-Kincaid).
The US school grade level needed to understand your text. Academic papers typically score 14-18 (postgraduate level).
0-100 scale (lower = harder). Academic writing: 10-40. Popular science: 50-60. Newspapers: 60-70.
Years of education needed. Academic papers: 14-18. Above 18 means even experts may struggle — simplify.
Unlike creative writing where active voice is preferred, academic writing uses passive voice strategically. The ideal range for a thesis is 15-25% passive sentences. Below 15% can sound too informal; above 30% becomes hard to follow.
"The data were collected using semi-structured interviews."
Focus on the action, not the researcher — standard in methodology sections.
"It was found that the results were affected by the variables that were identified."
Triple passive — confusing. Rewrite: "The identified variables affected the results."

Flesch-Kincaid grade level 14-18, Flesch Reading Ease 10-40, Gunning Fog 14-18. This means your writing is complex enough for academic standards but still followable by an educated reader.
No. If your Gunning Fog exceeds 20, even experts will struggle. Complexity should come from ideas and precise vocabulary — not from unnecessarily long sentences. Aim for clarity within formality.
