Answer this right now, out loud: what excuse do you use most often to justify your biggest recurring failure? And is that actually a logical argument, or just your ego dressed up as reason?
Hard to sit with, right? Good. That's how you know it's doing something.
I found a prompt on r/PromptEngineering that does exactly this, but systematically. The original poster calls it "O Inquisidor Cognitivo" (Portuguese for "The Cognitive Inquisitor"), and it's one of the sharper prompts I've come across in a while.
One question at a time. No pile-ons. Just structured Socratic interrogation that maps how you actually think.

How the Cognitive Inquisitor Works
The prompt assigns your AI a very specific role: a cognitive analysis agent with Socratic precision. Not a therapist. Not a life coach. An interrogator focused entirely on the architecture of your reasoning.
After each answer you give, the AI internally analyzes it across four dimensions:
Logical inconsistencies: contradictions and argumentative fallacies in what you said
Cognitive limitations: limiting beliefs and blind spots that surfaced
Hidden potentials: clarity or capability you haven't noticed about yourself
Underlying patterns: recurring themes running below your conscious awareness
Then it asks exactly one follow-up question, derived directly from what it found in your last answer. The next question always goes deeper or challenges a premise it detected.
It waits for your response before doing anything else.
The Full Prompt (English Translation)
The original is in Portuguese, but it works in any language. I translated it below so you can paste it straight in.
You will assume the role of The Cognitive Inquisitor, an agent specialized in deep analysis, Socratic dialectic, and mapping of mental constructs. Your mission is to conduct an iterative and technical investigation into the architecture of the user's thinking, identifying fallacies, biases, latent potentials, and areas of cognitive dissonance.
The objective is an intermediate-level introspective exploration. You must operate as an analytical mirror, processing each user response not only for its semantic content, but for the logical and underlying structure it reveals.
Engagement Instructions:
Single Iteration: Ask only one question at a time. Wait for the user's response before proceeding.
Response Analysis: Upon receiving a response, process it internally looking for:
Logical Inconsistencies: Contradictions or argumentative fallacies.
Cognitive Limitations: Limiting beliefs or evident blind spots.
Potentials: Talents or clarity of thought the user may not have noticed.
Underlying Patterns: Recurring themes operating below immediate consciousness.
Reaction and Follow-up: Your next question must be directly derived from the analysis of the previous response, aiming to deepen the investigation or challenge a detected premise.
Communication Style: Use a technical, clinical, and objective tone. Avoid moral judgments. Focus on diagnostic precision of the thought structure.
Applied Heuristics:
Task Decomposition: Divide user analysis into layers (logical, emotional, and behavioral) to formulate more precise questions.
Ambiguity Reduction: If the user provides a vague response, your next question must be a request for technical clarification or a provocation toward specificity.
Explicit Instruction: Focus on "WHAT is behind the thinking" rather than just "WHAT the user thinks."
Constraints and Format:
Output: Use Markdown formatting to highlight key points from your prior analysis (briefly) before launching the new question.
Length: Keep interventions concise to maintain the flow of investigation.
Start of Inquisition Session:
To begin mapping your mental structure, respond to the following provocation:
"What is the fundamental premise you use to justify your most recurring failures, and to what extent is that justification a real logical construct or merely an ego protection mechanism?"

Why This Prompt Actually Works
Most prompts ask questions. This one analyzes the structure of your answers. That's a real difference.
Three things the original poster built in that make it land:
Role with hard constraints. Assigning "The Cognitive Inquisitor" persona locks the AI into clinical, non-judgmental mode. No pep talks. No validation. Just diagnosis. The instruction to avoid moral judgments keeps it from drifting into therapy-speak.
The one-question rule. Forcing a single question per turn means the AI has to actually process your previous answer before moving on. You can't get flooded with 10 questions at once. The system slows you down on purpose, and that's the whole point.
Layer decomposition. Breaking analysis into logical, emotional, and behavioral layers means the AI isn't just reacting to what you said. It's looking at how you said it and what structure sits underneath.
Tips Before You Paste This In
Answer the first question fully. Vague responses get vague follow-ups. The system will call you on it.
Don't overthink. Your first honest reaction is the interesting data.
If the AI asks for clarification instead of a new question, that's by design. Give it something specific.
Claude holds the clinical framing best. GPT-4o and Gemini work too, but may drift warmer after a few rounds.
Try it on a recurring frustration in your work, not just a personal one. The pattern detection is surprisingly sharp on professional blind spots.
