Pre-mortem + Wildcards: How to Fix the Biggest LLM Blind Spots in Analysis and Forecasting

Key result

On its own, Opus 4.6 runs a pre-mortem in only 9 out of 100 cases. The best forecaster does it in 38. The difference isn't how much information the model gathered. It's what questions it asks itself afterward. CHAMPS KNOW shifts an LLM from "gather data → answer" mode into strategic-analyst mode with a single prompt, no fine-tuning. Three blocks the model almost never goes through on its own: P (if I'm wrong, why?), O (what am I missing?), W (what wild scenario changes everything?). The trick: block P instructs the model to challenge its own position right after forming it, and that's not a polite caveat but a forced hunt for a real counterargument.

01

TL;DR

Researchers compared what top forecasters and average ones lean on when they analyze hard questions. The verdict: the difference isn't search quality, it's the questions they ask themselves after the data is in. Top forecasters systematically do three things that ordinary LLMs almost never do unless told: they run a pre-mortem ("if I turn out to be wrong, why?"), look for alternative perspectives ("what am I missing?") and consider black swans ("what unlikely event would change everything?").

The main finding: By default, frontier LLMs spend ~94% of their effort on gathering information (H, "search") and nearly ignore the pre-mortem (P), other perspectives (O) and wildcards (W). Yet P, O and W are exactly what separate a sharp analyst from an average one. Claude Opus 4.6 ran a pre-mortem in only 9.5% of cases. The best forecaster did it in 37.8%. Worse still, LLMs systematically confuse rhetoric with intent: if a leader says "we will do this," the model reads it as a commitment rather than a negotiating move. It never asks, "why would he say that right now?"

The fix: explicitly instruct the LLM to walk through CHAMPS KNOW, Tetlock's 10-dimension framework for accurate thinking. Three underused dimensions matter most: P (what if I'm wrong?), O (which perspectives am I ignoring?), W (which black swan would change everything?). One prompt, one request, zero infrastructure.

Method Blueprint

The method fits in a single prompt, one request:

STEP 1: Norms and precedents (N) → What usually happens in similar situations?
STEP 2: Key players and incentives (K) → Who decides? Why right now?
STEP 3: Comparison classes (C) → What does this resemble from the past?
STEP 4: Pre-mortem (P) → If the forecast is wrong, why?
STEP 5: Other perspectives (O) → What am I missing?
STEP 6: Wildcards (W) → What's unlikely but changes everything?
STEP 7: Bottom line → Conclusion with a probability and the key arguments

Research and conclusion happen in one request. The structure swaps the LLM's default mode ("gather info → answer") for the mode of a strategic analyst.

Example

Task: Mark is the founder of an HR-tech startup. His big question: "Will Google launch a competing ATS (applicant tracking system) in the next 12 months, and should I delay my funding round?"

Prompt:

Analyze the following question as a strategic analyst, using the
CHAMPS KNOW structure. Go through each dimension in order:

**Question:** Will Google launch a competing ATS product (hiring
automation system) in the next 12 months?

**Context:** Google already runs Google for Jobs, the HR-tech market is growing,
competitors include LinkedIn, Greenhouse and Lever. I'm a startup with 200 clients
considering a funding round.

---

Go through each block:

**N — Norms and precedents:**
How does Google usually enter adjacent niches? What is typical of its
product expansion: build, buy, or partner?

**K — Key players and their incentives:**
Who inside Google makes this kind of decision? What incentive do they have
to launch an ATS specifically, and specifically now? What is shifting in their priorities
in 2025?

**C — Comparison classes:**
Which previous Google expansions does this resemble? How is this
situation different from those precedents?

**P — Pre-mortem (MANDATORY):**
Assume that 12 months from now Google has released a competing ATS.
Why might my analysis have underestimated this? Which signals am I probably
ignoring right now?

Now assume the opposite: 12 months from now Google still hasn't entered
the ATS market. Why? What held it back?

**O — Other perspectives:**
Which viewpoints on the situation haven't I considered? How does a
major investor see it? How does a Google manager who was asked
to build an ATS see it?

**W — Wildcards:**
What unexpected event could sharply shift the situation one way or
the other? For example: a regulatory change, an M&A deal,
a change in strategy?

---

**Bottom line:**
Based on the analysis above, estimate the probability that Google enters ATS
in the next 12 months. State the main argument for, the main argument
against, and what would change your estimate.

Result: The model will work through every block in order. In block K you'll get reasoning that goes beyond "Google is big" to "what is the product team's concrete incentive right now." In block P the model will argue against itself and may revise its estimate. In W you'll see scenarios like "if Microsoft buys Greenhouse, Google speeds up." The output won't be "probably yes/no" but a structured conclusion with concrete triggers for revisiting it.

04

Why It Works

An LLM's default mode is linear. The model gathers information, forms a position and defends it. If a text says "we will do this," it takes that as a signal without asking "why are they telling us this?" This isn't a quirk of one model; it's a pattern. The study showed that even the best frontier agent (Opus 4.6) ran a pre-mortem on its own in only 1 out of 10 cases.

LLMs are good at following a role. When you spell out the reasoning structure, the model executes it. It doesn't "think" differently; it generates text along a different pattern. The "P — pre-mortem" block literally changes the next chunk of generated text: the model is forced to look for counterarguments to the position it just formed.

Three levers for tuning the prompt: - Add "MANDATORY" to block P → the model won't skim it as a formality - Drop blocks M and S → if the question needs no math or rewording, the prompt gets shorter - Replace general context with hard data → block K gets sharper when you feed it real facts about the company or person

05

Prompt Template

Analyze the following question as a strategic analyst.
Go through each block in order:

**Question:** {question to analyze}

**Context:** {known facts, data, situation}

---

**N — Norms and precedents:**
What typical behavior patterns apply to this situation?
What usually happens in similar cases?

**K — Key players and incentives:**
Who makes the decisions? What are their real incentives right now?
Why might they do this (or not do it) at this moment?

**C — Comparable situations:**
What does this resemble from the past? How is this case different?

**P — Pre-mortem (MANDATORY):**
Assume my forecast turns out wrong. Why would that happen?
Which factors am I probably underestimating right now?

Now assume the opposite outcome. What caused it?

**O — Other perspectives:**
Who might disagree with me, and why? Which viewpoints
haven't I considered?

**W — Wildcards:**
What unlikely but realistic event could change everything?
One or two scenarios.

---

**Bottom line:**
Based on the analysis above: {question to analyze}: what is most likely,
the main arguments for and against, and what would change your estimate?

Placeholders: - {question to analyze} — a concrete question: "will X enter market Y," "should I do Z," "how will a competitor react" - {known facts} — what you already know: news, data, rumors, history


🚀 Quick start — paste into the chat:

Here is a template for structured strategic analysis (CHAMPS KNOW).
Adapt it to my task: [your task or question].
Ask clarifying questions to fill in the context.

[paste the template above]

The LLM will ask what question you're analyzing and what context you have, because block K (incentives) needs concrete data about the actors or the analysis stays generic.

06

Limitations

⚠️ Questions without a clear analytical structure: Pre-mortems and wildcards shine on strategic questions with concrete players and incentives. On creative or subjective tasks ("write a piece about nature") the structure adds nothing.

⚠️ Quality depends on the context in the prompt: Block K ("incentives of key players") will be shallow unless you give the model real data about the person or company. Without context it produces generic patterns, not a specific analysis.

⚠️ It doesn't replace domain expertise: The study showed that even with the right reasoning structure, the LLM sometimes lacks the necessary context (for example, on the specifics of Nigerian union negotiations). Structure improves reasoning, but it can't fill a knowledge gap.

⚠️ An ensemble beats a single run: The best results in the study came from averaging several independent runs. In a chat, that means: run the prompt twice in separate sessions and compare the conclusions.

07

How They Tested It

The FutureSearch team built BTF-2, a set of 1417 forecasting questions covering October–December 2025. The twist: the questions came with a frozen corpus of 15 million documents captured at the moment the questions were posed. That let them rerun agents over and over on the same data without the agents "peeking" into the future via the internet.

Four top frontier agents (Opus 4.6, Gemini 3.1 Pro, GPT-5.4, Grok 4.20) researched the questions on their own, made forecasts and left full traces: every search query, every page read, every intermediate thought. The researchers then built a SOTA forecaster from an ensemble of agents plus extra techniques, and it beat every single agent on accuracy.

The most interesting part: they took Tetlock's CHAMPS KNOW framework (10 dimensions of good forecasting, proven in randomized studies with humans) and asked Gemini to score every final answer on those dimensions. It turned out the SOTA forecaster leaned on the pre-mortem (P) 4 times more often than the best single agent, and on wildcards (W) almost 10 times more often. In parallel, human experts manually reviewed the 130 worst Opus 4.6 forecasts and found one recurring pattern: the agent took leaders' rhetoric as a commitment and never asked "why are they saying this right now?"

Adaptations and Extrapolations

🔧 Adaptation: A quick pre-mortem without the full structure

If you don't need the full CHAMPS KNOW, just add P and O to any request:

[Your usual question to the LLM]

After your answer, be sure to add two blocks:

**If I'm wrong, why?**
Assume your conclusion turns out to be wrong.
Which factors are you probably underestimating?

**What am I missing?**
Which perspectives or data did you not consider in the main answer?

This is the minimal working version: two extra paragraphs change the quality of the analysis without rewriting the whole prompt.


🔧 Adaptation: Modeling incentives before a negotiation

Built on the finding that "LLMs confuse rhetoric with intent." Use it before a negotiation, a pitch, or a conversation with a partner or investor:

I'm preparing for a negotiation with {name/role}.

Their public position: {what they are saying}

Answer three questions:
1. What REAL incentives sit behind this position?
   What do they actually need?
2. What would be a face-saving way out of their current position?
3. Under what conditions would they back off their stated position,
   and what would that look like from the outside?

Research digest

Key result

On its own, Opus 4.6 runs a pre-mortem in only 9 out of 100 cases. The best forecaster does it in 38. The difference isn't how much information the model gathered. It's what questions it asks itself afterward. CHAMPS KNOW shifts an LLM from "gather data → answer" mode into strategic-analyst mode with a single prompt, no fine-tuning. Three blocks the model almost never goes through on its own: P (if I'm wrong, why?), O (what am I missing?), W (what wild scenario changes everything?). The trick: block P instructs the model to challenge its own position right after forming it, and that's not a polite caveat but a forced hunt for a real counterargument.

Principle

An LLM works linearly. It gathers information → forms a position → defends it. If a source says "we will do this," it takes that as fact. It doesn't ask: "why are they saying this right now?" That's a pattern, not a bug in one particular model. CHAMPS KNOW breaks this cycle: when P comes right after the conclusion is formed, the model is forced to generate text in the opposite direction, looking for what it just ignored. The model doesn't "think" differently. It generates text along a different template. But the result is different.

Why it works

After gathering information, the brain locks onto the first plausible version. A model has the same effect; call it anchoring. Ask "could I be wrong?" and the model adds a caveat, then keeps pushing its line. Instruct it "assume you're wrong, explain why" and the model goes looking for a real counterargument. Those are different requests with different results. The study showed that even frontier models spend ~94% of their effort gathering information and barely touch P, O, W, the very blocks that separate accurate analysis from average. The structure simply forces the model to reach those blocks instead of stopping after the first plausible answer.

When to apply

Strategic questions with concrete players and incentives: competitor analysis, forecasting company decisions, assessing deal risks, hiring key people, especially when the stakes are high and you want to be wrong as rarely as possible. Works best when you can give the model real data about the participants; without it, block K (incentives) turns into fluff. NOT suited for creative tasks or questions without concrete participants: "write a piece," "which is more interesting," "how do I polish my style."

Mini recipe

1. Take the template: N → K → C → P → O → W → bottom line. That's the whole framework. You can drop blocks you don't need for a given task. 2. Fill in the context: without real facts about the company or person in block K, the model will produce generic patterns, not sharp analysis. Give it something concrete. 3. Mark block P as "MANDATORY": without that, the model goes through it as a formality. With it, the model is forced to find a real counterargument to its own position. 4. Run it twice in separate sessions: two independent runs give different wildcards and different pre-mortems; compare the conclusions and take the overlap.

Examples

[BAD]: `Will Google enter the hiring automation software market in 2025?` [GOOD]: `Analyze the question as a strategic analyst, going through each block in order. Question: Will Google launch a competing hiring automation product in the next 12 months? Context: Google already runs Google for Jobs, the market is growing, competitors include LinkedIn, Greenhouse and Lever. N: How does Google usually enter adjacent niches: build, buy, or partner? K: Who inside Google makes this kind of decision? What incentive do they have right now? C: Which past Google expansions does this resemble? How is it different? P (MANDATORY): Assume that 12 months from now Google has launched. Why did my analysis underestimate this? Now assume the opposite: it never launched. What held it back? O: Which viewpoints haven't I considered? W: What unexpected event sharply changes the situation? Bottom line: probability of a launch, the main argument for, the main argument against, what would change the estimate.`

In plain words

The problem is that ordinary AI assistants think too straight and too predictably. Ask a model to forecast something and it behaves like a diligent straight-A student: it collects facts, glues them into a logical chain and hands you an answer it wholeheartedly believes. The root of the trouble is linear thinking: LLMs tend to confirm the first hypothesis that comes along instead of putting it on trial. They don't "think in reverse" by default, so their forecasts often come out shallow and go down the drain at the first contact with reality.

It's like asking a die-hard fan whether his team will win the next game. He'll bury you in stats about past wins but completely ignore that the star striker has a bad knee and the ref botched a similar call yesterday. On paper the forecast is justified, but in practice it's an information bubble. The model acts as the defense attorney for its own idea, when what you really need is a prosecutor who tears it apart before you put money on that forecast.

To lift an AI to the level of a top analyst, you have to make it use strategic reasoning through three concrete methods. The first is the pre-mortem: the model must imagine its forecast has already failed and explain why. The second is hunting for alternative perspectives, where the agent has to find arguments that directly contradict its current position. And the third is accounting for black swans, meaning a breakdown of unlikely but catastrophic events. The study showed that even strong models like Opus do this on their own in only 1 out of 10 cases, so you literally have to rub their nose in these tasks.

The principle is universal and works far beyond boring reports. Whether it's launching a startup, planning a funding round or guessing whether a competitor will ship a similar product in six months, the mechanics of a critical filter are the same everywhere. It was tested on forecasters, but the method applies to any complex decision where mistakes are expensive. If you just ask an AI "what will happen?", you get tea-leaf reading. If you force it to look for points of failure, you get a strategy.

Bottom line: the difference between an average forecast and a brilliant insight isn't the amount of data, it's the ability to attack your own conclusions. Stop using LLMs as an encyclopedia and start using them as sparring partners whose job is to find the flaw in your plan. Three methods of critical analysis turn an ordinary chat into a serious decision-making tool. Whoever keeps trusting linear answers from neural nets will eventually run into a reality that simply wasn't in the prompt.
