Use when exploring alternative scenarios, testing assumptions through "what if" questions, understanding causal relationships, conducting pre-mortem analysis, stress testing decisions, or when user mentions counterfactuals, hypothetical scenarios, thought experiments, alternative futures, what-if analysis, or needs to challenge assumptions and explore possibilities.

This skill guides you through counterfactual reasoning (what would have happened differently?), scenario exploration (what could happen?), pre-mortem analysis (imagine failure, identify causes), and stress testing decisions against alternative futures. ## When to Use Use this skill when: - **Testing assumptions**: Challenge underlying beliefs by asking "what if this assumption is wrong?" - **Pre-mortem analysis**: Imagine project failure, identify potential causes before they occur - **Causal inference**: Understand "what caused X?" by asking "would X have happened without Y?" - **Scenario planning**: Explore alternative futures (best case, worst case, surprising case) - **Risk identification**: Uncover hidden risks through "what could go wrong?" analysis - **Strategic planning**: Test strategy robustness across different market conditions - **Learning from failures**: Counterfactual analysis "what if we had done X instead?" - **Decision stress testing**: Check if decision holds across optimistic/pessimistic scenarios - **Innovation exploration**: "What if we removed constraint X?" to unlock new possibilities - **Historical analysis**: "What would have happened if..." to understand key factors Trigger phrases: "what if", "counterfactual", "hypothetical scenario", "thought experiment", "alternative future", "pre-mortem", "stress test", "what could go wrong", "imagine if", "suppose that" ## What Is It? **Hypotheticals and Counterfactuals** combines forward-looking scenario exploration (hypotheticals) with backward-look
