Structured Analytic Techniques (SATs) Index

SkillDev tools

Use when the user asks "which SAT should I use for X?", wants the index of Structured Analytic Techniques, or is choosing between ACH, key-assumptions-check, red-team-analysis, indicators of change, etc.

Available today. Use it from your connected AI after setup.

Connect ahel once, and every AI you use reads what you have installed.

Then ask your AI: use the Structured Analytic Techniques (SATs) Index skill

What this skill tells your AI

The instructions your AI receives, as published by liberty91ltd/cti-skills in skills/structured-analytic-techniques/SKILL.md and read by ahel’s review.

SATs are formal methods that externalise analytical thinking, making it transparent, challengeable, and less susceptible to cognitive biases. Choose the right technique based on the analytical challenge.

When to Use SATs

  • When the stakes are high (wrong answer = significant consequence)
  • When multiple plausible explanations exist
  • When cognitive biases are likely (confirmation, anchoring, availability)
  • When you need to communicate your reasoning transparently
  • When building on analysis from multiple analysts

Technique Categories

Diagnostic Techniques

Purpose: Evaluate existing analysis for quality and bias.

TechniqueWhen to UseSkill
Key Assumptions CheckBefore or after any major assessment — surface and challenge unstated assumptionskey-assumptions-check
Quality of Information CheckWhen evidence quality is uncertain — assess source reliability and information gapsUse source-assessment skill
Indicators ValidationWhen monitoring a developing situation — define observable markers of changePart of horizon-scanning

Contrarian Techniques

Purpose: Challenge prevailing judgments and expose blind spots.

TechniqueWhen to UseSkill
Analysis of Competing HypothesesMultiple plausible explanations — systematically evaluate each against evidenceach
Devil's Advocate / Red TeamWhen consensus is strong — deliberately argue the opposing positionred-team-analysis
What-If AnalysisExplore low-probability but high-impact scenariosPart of horizon-scanning
High-Impact / Low-ProbabilityEnsure unlikely but catastrophic scenarios are consideredCombine threat-assessment + horizon-scanning

Imaginative Techniques

Purpose: Generate new ideas, hypotheses, and indicators.

TechniqueWhen to UseSkill
BrainstormingGenerate hypotheses, IOC types to collect, detection approachesNo dedicated skill — apply freely
Scenario DevelopmentExplore multiple futures for strategic planninghorizon-scanning
Indicators GenerationDefine early warning indicators for a scenariohorizon-scanning

Decision Guide: Which Technique?

Are you evaluating WHO did something?
  → ACH (ach skill)

Are you assessing a THREAT?
  → Threat Assessment (threat-assessment skill)

Are you challenging your OWN analysis?
  → Key Assumptions Check (key-assumptions-check skill)

Are you challenging SOMEONE ELSE's analysis?
  → Red Team / Devil's Advocate (red-team-analysis skill)

Are you looking FORWARD (emerging threats)?
  → Horizon Scanning (horizon-scanning skill)

Are you unsure if your evidence is RELIABLE?
  → Source Assessment (source-assessment skill)

Do you have MULTIPLE plausible explanations?
  → ACH (ach skill)

Combining Techniques

For complex assessments, combine techniques:

  1. Key Assumptions Check first (surface your assumptions)
  2. ACH for the core analysis (evaluate hypotheses)
  3. Red Team to challenge the result (stress-test conclusions)
  4. Horizon Scanning for forward-looking implications
