SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Helps individuals and teams improve decision quality by applying a curated set of mental models, structured critique, and decision-process tooling to surface hidden assumptions and reduce cognitive bias.

Core Features & Use Cases

Socratic questioning to surface hidden assumptions and force explicit reasoning.
Bias detection & probabilistic thinking to calibrate confidence and reduce overconfidence.
Decision frameworks (pre-mortems, decision journals, and second-order thinking) to systematize risk assessment and scenario planning.
Systems thinking & inversion to map feedback loops, leverage points, and failure modes across domains.

Quick Start

Initiate a thinking-session by asking the AI to apply mental models to a decision and run a structured analysis.

FAQPage Schema

How do I apply mental models to improve decision-making and reduce cognitive bias?▼

Applying mental models to improve decision-making involves using structured frameworks like Socratic questioning and inversion to surface hidden assumptions. This Skill integrates these models to systematically reduce cognitive bias and force explicit reasoning during risk assessment.

What is a pre-mortem analysis and how does it help with scenario planning?▼

A pre-mortem analysis is a decision framework that imagines a future failure to identify potential causes beforehand. It helps with scenario planning by mapping failure modes and systematizing risk assessment before committing to a strategy.

How do I run a structured decision journal session for product and engineering choices?▼

Running a structured decision journal session involves documenting your probabilistic thinking, confidence calibration, and expected outcomes for product and engineering choices. This Skill facilitates that process by applying structured critique to capture explicit reasoning.

Can I use systems thinking to map feedback loops and leverage points for strategy contexts?▼

Yes, you can use systems thinking to map feedback loops and identify leverage points for strategy contexts. This Skill applies systems thinking to analyze complex interactions and surface hidden assumptions across product, engineering, and strategy domains.

What is the best way to detect bias and calibrate confidence in probabilistic thinking?▼

The best way to detect bias and calibrate confidence is through structured decision frameworks that enforce probabilistic thinking. This Skill uses Socratic questioning and second-order thinking to reduce overconfidence and surface hidden assumptions.

When should I use inversion versus second-order thinking for risk assessment?▼

Use inversion to identify how a plan might fail and second-order thinking to evaluate the downstream consequences of a decision. Both decision frameworks systematize risk assessment by mapping failure modes and feedback loops across domains.
