Teams hand-simulate a simplified content-ranking algorithm, watching how small rules about engagement can snowball into unintended outcomes like an echo chamber.

Setup

Print or hand-copy the essential prompt for Social-Media Algorithm Simulator, then set out only paper, pencils, and the common or recycled items needed for one test. Use a tabletop representation whenever the original version mentions a room, specialized device, or digital tool; the learning comes from the decisions and evidence, not elaborate scenery.

Activity

  1. Define the central success test in Social-Media Algorithm Simulator and make a paper planning sheet for the inputs, actions, and expected result.
  2. Represent the system without electronics by using labeled cards, paper controls, tokens, a ruler, or a student acting as the device; follow the same cause-and-effect rules described in the project.
  3. Run at least three cases, including one difficult or unexpected case, and record input examples, operating rules, predicted outputs, and actual outputs.
  4. Revise one rule, layout, mechanism, or decision after the failed case, repeat it, and explain with the recorded evidence whether the change worked.

Done when: The group has completed Social-Media Algorithm Simulator when it can present the round-by-round results and propose one rule change that would reduce the unintended effect and point to the observation, measurement, comparison, or trial that supports its conclusion.

Steps

  1. Read the simple ranking rule, such as show more of what gets clicked, and predict what kind of content will dominate after several rounds.
  2. Run the simulation by hand for a few rounds, sorting post cards based on the engagement rule.
  3. Track the results, find the feed has narrowed to one extreme type of content faster than expected, and identify which rule caused the snowball.
  4. Present the round-by-round results and propose one rule change that would reduce the unintended effect.
