Write and retest a financial decision rule
See this course’s project requirements
An original financial decision-case comparison and rule test covering anchored prices, sunk costs, recurring charges and delayed spending with a prewritten decision rule.
Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.
What to include
- A controlled price-anchor comparison and choice explanation.
- A sunk/avoidable cost decision table.
- A twelve-month price comparison and crossover calculation.
- A dated value-comparison record and access-constraint note.
- A framed-choice comparison with explicit design limitations.
- A complete financial decision-case comparison and rule-retest log.
Review and revise
Use these criteria to check your work and choose what to improve.
- All supplied records reconcile and the decision uses the named case rules.
- Calculations show units, intermediate values and a second check.
- Changed-input practice revises the affected result and identifies uncertainty.
- The final project combines six lesson records, separates fictional assumptions from current rules, and states a supported next step.

The idea in everyday life
This is an original fictional practice case. No account, payment, personal record or outside participation is required. Rule: compare qualifying delivered totals, exclude unrecoverable past payments, and pause if recurring cost or payment capacity is unknown. Case A shows a $100 anchor/$70 current offer versus qualifying $60 offer.
A useful rule responds to value and constraints, not the anchor or past spending; test it on cases designed to tempt an error.
Write and retest a financial decision rule — worked practice
A useful rule responds to value and constraints, not the anchor or past spending; test it on cases designed to tempt an error.
Use paper or a local table; label all amounts as fictional USD unless the case names another unit. Rule: compare qualifying delivered totals, exclude unrecoverable past payments, and pause if recurring cost or payment capacity is unknown. Case A shows a $100 anchor/$70 current offer versus qualifying $60 offer.
Financial decision rule inputs
Paste at A1.
| AInput or record | BSupplied value |
|---|---|
| Case A anchor USD | 100 |
| Case A current USD | 70 |
| Qualifying alternative USD | 60 |
| Other recurring offer USD/month | 5 |
| Other offer term | Unknown until changed case |
| Pause rule | Recurring total or capacity unknown |

1. Step 1: Write the rule before revisiting the case
Write the rule before revisiting the case.
You should see: Current equivalent cost and feasibility govern; unknown recurring cost triggers pause.
A useful rule responds to value and constraints, not the anchor or past spending; test it on cases designed to tempt an error.
2. Step 2: Apply it to the price-anchor case
Apply it to the price-anchor case.
You should see: Choose $60 under the stated equivalent features.
Keep this intermediate result so the final decision can be checked.
3. Step 3: Test a second case with $5/month and unknown minimum term
Test a second case with $5/month and unknown minimum term.
You should see: Pause and verify the term before estimating total cost.
Keep this intermediate result so the final decision can be checked.
4. Step 4: Compile the decision-case comparison and rule-retest record
Compile the decision-case comparison and rule-retest record.
You should see: Keep anchor, sunk cost, horizon, timing and framing calculations with the two retest decisions and limits.
Keep this intermediate result so the final decision can be checked.
What to finish
A complete financial decision-case comparison and rule-retest log.
Watch for this
Claiming a small exercise eliminates all bias or proves a person is irrational.
How can I tell I understand it?
Apply a prewritten money-choice rule to anchor and recurring-cost retest cases on the supplied changed case while preserving the stated rule and checking the final record.
