How the Rulside method works

  1. Read the brief and separate facts from assumptions.
  2. Apply one technique to fictional, controlled material.
  3. Check the decision and record its limitations.
  4. Solve a complete case with greater autonomy.

Three levels covering the same curriculum

  • Explorer: step-by-step instructions.
  • Analyst: less help and more independent decisions.
  • Expert: a complete investigation with few hints.

Responsible practice

Rulside uses fictional scenarios and teaches learners to document uncertainty. It does not ask them to investigate real people or access private data.
