Choose the criteria before comparing

Decide what matters before you see a confident ranking. For a service provider, the criteria might be licence, availability, written price, warranty, travel distance, and references. For a household purchase, repairability or ongoing cost may matter more than a long feature list.

If the criteria reflect a family value or trade-off, discuss that first. The model can organize the choice but should not quietly decide what matters most.

Supply the evidence yourself

Paste only information you are permitted to share, or use links and notes from public sources. Tell the model to leave a cell blank when the evidence is missing. This reduces the chance that a plausible detail appears as a fact.

  • Separate one-time price from recurring cost.
  • Keep provider claims separate from independent evidence.
  • Add the date because prices and availability change.
  • List questions that still need a phone call or written answer.

Make the decision outside the model

Review the comparison with the people affected. Check the most important details at the original source. Then decide using your actual budget, schedule, risk tolerance, and relationships. The comparison is working material, not a verdict.

Practise on real work

Build a source-based comparison

Use two or three public, low-stakes options. Remove addresses, account details, and family names.

Prompt to adapt

Compare these options only from the information I provide. Use these criteria: [criteria]. Create columns for evidence, missing information, recurring cost, risk, and questions to verify. Do not rank the options or fill gaps from memory. Add the source beside each fact.

Judgment checks

  • Did you choose the criteria before viewing the table?
  • Can you trace every important detail to a current source?
  • Which trade-off still needs a family decision?

Keep these points

  • Set the criteria before asking for a comparison.
  • Leave missing evidence visible.
  • Use the table to support a family decision, not replace it.
