What Breaks (Contrarian Correction)

Most guides tell you to dump all your files into a notebook at once and ask "summarize everything." That is backwards.

Loading raw documents without a structural primer causes NotebookLM to weigh all text equally, blending low-value headers or introductory fluff with core data. You must anchor the notebook with a strict citation policy first.
