Cowork can assemble a polished report or deck from your source folder. Polished is not the same as trustworthy. Every major claim in the artifact must trace back to a source you approved. Provide a template, voice constraints, and a list of what must not be claimed , not just what should be included. Review figures, captions, and speaker notes separately. They fail differently than body text. You own the final artifact. You are responsible for what it says.

Edward Tufte spent decades arguing that most data presentations obscure more than they reveal , through chartjunk, overloaded slides, truncated axes, and disconnected captions. His phrase "evidence corruption" applies to slides that prioritize visual appeal over analytical honesty. His critique of the PowerPoint culture in engineering organizations was not a design complaint; it was a claim about how presentation format shapes what decision-makers believe. A deck that looks good and misleads is worse than a messy document that tells the truth.
