A thinking aid.

Segal (1987) sketched a hands-on way to plan a paper.

The author built a 3-D outline from index cards.

Cards sit in columns on a table so you can slide, add, or toss ideas as the story grows.

No data were collected; it is a how-to guide for writers.

The stacked-card method turns writing into a physical task.

Moving cards shows gaps, repeats, and order problems at a glance.

The paper claims this speeds up drafting and raises clarity.

Gilroy et al. (2019) extends the same spirit into the digital age.

Where Segal (1987) lets you shuffle paper in the open, Gilroy shows how to shuffle code and data on GitHub so others can replay your moves.

Both tools aim for the same target: transparent, re-arrangeable science.

Sacco et al. (2012) and Twyman (2025) also give practitioner-level scaffolds, but for therapy and system change rather than writing.

They fit side-by-side: use cards to plan the manuscript, then use GitHub to share it, FAP rules to shape client talk, and Twyman’s scale-up steps to move findings into schools.

You can build the card outline today.

Grab index cards, one idea per card, and line them up in story order.

When results surprise you, slide a card instead of rewriting whole pages.

The tactile step slows you down just enough to spot weak links before reviewers do.
