Lesson 20: Ask for a table, not a paragraph.

Models can pull specified fields out of messy text into a structure you define. The whole trick is that you choose the columns — because the columns are the analysis.

Why this matters: Comparing six studies in prose is slow and error-prone. Pulled into a table with the columns you chose, the pattern is visible in ten seconds and the gaps announce themselves.
