AC9.3 · learner packet

Cooperation
and conflict.

Harbour Commons protocol and five records for testing claims without turning learners into the experiment.

No real stakes. No labels.

Tokens have no connection to grades, money, food, privileges, or access. Only anonymous group totals are recorded. Participant, observer, analyst, recorder, and independent-study routes are equivalent.

Fictional simulation · Weeks 3–5

Harbour Commons

A coastal growing cooperative draws water from a shared fictional reservoir. The exercise observes aggregate patterns under different rules; it does not identify winners, losers, or personality types.

Starting stock

60

fictional water tokens at the start of every condition

Private action

0 · 2 · 4 · 6

tokens requested per role card and round

Renewal

½ remains

Add half the remaining stock after withdrawals, never exceeding 60

Round rule

Ending stock = starting stock − aggregate requests. If requests exceed stock, record unmet demand and set stock to zero. Renewal = half the ending stock, rounded down. Next stock = ending stock + renewal.

Condition A · rounds 1–3

Baseline

No discussion. Private action slips. Publish group requests, unmet demand, and stock only.

Condition B · rounds 4–6

Communication

Two minutes of discussion before each round. Agreements are not enforced.

Condition C · rounds 7–9

Self-made rule

The group writes one allocation or replenishment rule plus a review process.

Condition D · rounds 10–12

Unequal capacity

Fictional role cards change stated needs. Cards are random and never tied to learner identity.

Safety and validity rules

  • Reset stock to 60 before every new condition.
  • Record anonymous group totals only; destroy private action slips after totals are checked.
  • No real reward, penalty, deception, forced disclosure, or public individual comparison.
  • Stop a round if privacy fails, instructions change mid-round, or a learner withdraws consent.
  • Record deviations and missing data instead of quietly repairing them.
Tool 01 · Week 3

Question and preregistration

Commit to a narrow comparison before seeing the results. A changed prediction remains visible in the revision record.

Tool 02 · Weeks 1–5

Source evidence audit

Use one copy per source. Do not treat a historical case, mathematical model, laboratory experiment, and field study as the same kind of evidence.

Confidence in the narrow claim
Tool 03 · Week 4

Anonymous round log

Record group totals and protocol quality. Keep private actions out of the dataset and portfolio.

Label condition, outcome, scale, units, and missing data. A line between rounds does not itself prove causation.

Tool 04 · Weeks 1 and 6

Claim ladder

Each rung needs more support than the one below it. Do not climb by changing vocabulary alone.

01 · Recorded observation

What appears directly in a source or anonymous dataset?

02 · Narrow inference

What relationship might explain the observation here?

03 · Mechanism explanation

What process is proposed, and what evidence tests it?

04 · Transfer claim

Where else might the finding apply, and what differs there?

05 · Political conclusion

What should people do—and what additional values or evidence does that require?

A simulation result cannot prove:

that people are naturally good or selfish; that one institution is universally legitimate; that punishment is just; or that a political identity must be adopted.

Tool 05 · Week 6

Report and revision planner

Make the method reproducible, the evidence inspectable, and the limits impossible to miss.
