Deep research

Turn a broad question into a cited decision brief

Ask Gemini to act as a skeptical analyst that separates verified facts, inferences, and unknowns, keeps dates beside time-sensitive claims, and ends with a decision table you can act on.

プロンプト

Act as a skeptical research analyst. Investigate [TOPIC] for [AUDIENCE]. Separate verified facts, reasonable inferences, and unknowns. Use primary sources where possible, include dates beside time-sensitive claims, and finish with a decision table covering evidence, trade-offs, confidence, and next action. If a claim cannot be sourced, say so rather than guessing.

変数を置き換える

[TOPIC]

The question or decision, stated as narrowly as you can.

[AUDIENCE]

Who reads the result — changes depth and tone.

どのモデルを使うか

  • Gemini 3.1 ProLonger, source-grounded reasoning benefits from the Pro tier; Flash is fine for quick scans.

入力例

  • [TOPIC] = "Should a 5-person startup self-host analytics or use a SaaS in 2026?" [AUDIENCE] = "a non-technical founder".

この構造が機能する理由

  • Forcing a facts / inferences / unknowns split stops the model from smoothing over uncertainty.
  • Requiring dates beside time-sensitive claims surfaces stale information.
  • A decision table converts prose into something you can actually choose from.

よくある失敗と修正

The model invents sources or citations.

修正: Add: "List only sources you can name; mark anything unsourced as UNVERIFIED." Then spot-check the named sources.

Answer is generic.

修正: Narrow [TOPIC] and add constraints (budget, region, timeframe).

既知の制限事項

  • Model outputs can still contain confident errors — verify sources before acting.
  • Freshness depends on the model and whether web/grounding tools are enabled.

よくある質問

Does this guarantee accurate citations?

No. It reduces vague hand-waving, but you must still open and verify each named source. Treat unsourced claims as unverified.
