--- name: counterfactual-thinking description: Apply counterfactual thinking to explore "what if" alternative histories and understand causation. Use when the user needs to analyze past decisions, understand what truly caused an outcome, learn from mistakes without hindsight bias, or evaluate whether different choices would have led to better results. --- # Counterfactual Thinking **Counterfactual thinking** asks "What if things had been different?" It constructs alternative histories — scenarios where a key variable changed — to understand causation, learn from the past, and make better decisions going forward. Used by historians (what if D-Day had failed?), safety engineers (accident root cause analysis), strategists (what if we'd entered the market earlier?), and psychologists (regret and learning). It separates what was **necessary** from what was **contingent**, revealing where interventions would have mattered most. --- Analyze the current topic or situation under discussion using **counterfactual thinking**. Explore alternative histories to illuminate causation and extract lessons. Apply this framework to whatever the user is currently working on or asking about. --- ## Step 1: Establish the Factual History Before exploring alternatives, nail down what actually happened: - What was the **sequence of events**? Create a clear timeline. - What were the **key decision points** — moments where things could have gone differently? - What was the **outcome** — and is it clearly positive, negative, or mixed? - Who were the **key actors** and what were their motivations? - What were the **conditions and constraints** at the time? - What information was **available vs. unavailable** to decision-makers at each point? ## Step 2: Identify Pivotal Moments - Which moments were **genuinely pivotal** — where a different choice would have led to a significantly different outcome? - Distinguish between: - **Necessary conditions**: Without this, the outcome could not have occurred. - **Sufficient conditions**: This alone was enough to cause the outcome. - **Contributing factors**: These increased the probability but weren't strictly necessary. - **Background conditions**: These were present but didn't actively cause the outcome (like oxygen in a fire analysis). - Rank the pivotal moments by **impact** — which change would have altered the outcome most? ## Step 3: Construct Counterfactual Scenarios For the **top 3-5 pivotal moments**, construct detailed alternative histories: ### Counterfactual 1: "What if [X had been different]?" - **The change**: What specifically is different? (Keep it minimal — change one thing at a time.) - **Plausibility check**: Could this alternative have reasonably occurred? Reject impossible counterfactuals. - **Trace the cascade**: - Immediately after the change: what happens differently? - Short-term consequences (days/weeks) - Medium-term consequences (months) - Long-term consequences (years) - **Second-order effects**: How do other actors respond to this different path? - **Best estimate of alternative outcome**: Better, worse, or just different? - **Confidence level**: How confident are you in this counterfactual trajectory? (Nearer pivots are more predictable; further ones are speculative.) *Repeat for Counterfactuals 2-5.* ## Step 4: Upward vs. Downward Counterfactuals ### Upward Counterfactuals ("It could have been better") - What changes would have led to a **better outcome**? - What was the **best realistic alternative path**? - What **opportunities were missed**? - What should have been done differently, given what was knowable at the time? (Avoid hindsight bias — only use information that was available.) ### Downward Counterfactuals ("It could have been worse") - What changes would have led to a **worse outcome**? - How close did we come to **disaster**? - What **lucky breaks** occurred that we might not appreciate? - What **safeguards or good decisions** prevented worse outcomes? This dual exercise prevents both complacency ("things went fine") and excessive regret ("we should have done everything differently"). ## Step 5: Causation Analysis The counterfactuals reveal what actually caused the outcome: - **Robust causes**: Factors that appear in every counterfactual where the outcome changes. These are the true drivers. - **Fragile causes**: Factors that only mattered because of specific other conditions. - **Overdetermined outcome**: Was this outcome likely regardless of any single change? (Multiple sufficient causes.) - **Underdetermined outcome**: Was this outcome highly contingent on specific, unlikely events? (Luck played a big role.) - **Necessary vs. sufficient**: Which factors were necessary (without them, outcome changes) vs. merely contributing? ## Step 6: The Hindsight Bias Correction A critical check — separate what we know **now** from what was knowable **then**: - Were the decision-makers acting **reasonably** given available information? - What information did they **lack** that makes the outcome obvious in retrospect? - Would a **reasonable, well-informed person** at the time have made a different choice? - Are we **judging the decision by its outcome** rather than by its quality at the time of making? - Distinguish: - **Bad decision, bad outcome** → Learning opportunity (process was flawed) - **Good decision, bad outcome** → Bad luck (process was sound; don't overreact) - **Bad decision, good outcome** → Good luck (dangerous to repeat) - **Good decision, good outcome** → Skill (but verify it wasn't also luck) ## Step 7: Extract Actionable Lessons - What **general principles** do the counterfactuals reveal about what drives outcomes in this type of situation? - What **early warning signs** should have been heeded (and should be watched for in the future)? - What **decision-making processes** should change? - What **contingency plans** should be in place for similar situations? - What was the **most important single thing** that could have been done differently? - Crucially: **What should we do differently next time**, without the benefit of hindsight? --- Counterfactual thinking is not about regret or wishful thinking — it's a rigorous tool for understanding causation. By asking "what would have happened if..." we discover what actually mattered, what was luck, and what lessons transfer to the future. History happened once; counterfactuals let us run the simulation again.
