“In God we trust; all others must bring data.” — W. Edwards Deming

Today’s tip: The Evidence-Lock Prompt (ELP).
Force accuracy by giving your model an EVIDENCE box and banning outside knowledge. This simple constraint (a cousin of retrieval-augmented generation) slashes hallucinations and makes outputs audit-ready.

Copy-paste template (use as-is):
“Use only the facts inside the EVIDENCE box. If any required info is missing, write ‘Not in evidence.’ Do not guess. Write the final answer only.
EVIDENCE:

• [Fact 1]

• [Fact 2]
  TASK: [What to produce, who it’s for, length limit, tone]
  FORMAT: [Bullets/JSON/table/etc.]”

Example:
“Use only the EVIDENCE.
EVIDENCE: - Q3 MRR £412k; churn 2.1%; top driver: onboarding emails.
TASK: Draft a 120-word exec update with one next action.
FORMAT: 3 bullets + 1 action.”
→ Output focuses on those numbers, flags gaps with “Not in evidence,” and proposes a specific onboarding experiment.
