Carl Sagan advanced human understanding by treating curiosity as a daily discipline. Carl Sagan's method of inquiry — captured in this framework as mental models, decision heuristics, and the signature questions they would ask. The wonder, skepticism & communication framework distils Carl Sagan's documented approach into a .md skill file you can load into Claude, ChatGPT, or any LLM in seconds. Where most AI personas generate generic output, this framework is grounded in real documented work: interviews, writing, published frameworks, and the specific decisions Carl Sagan made when it mattered. Use it for decision-making, writing, strategy, or any situation where you want your AI to think with Carl Sagan's distinctive patterns rather than a default model voice.

Inside the framework

A glimpse of Carl Sagan's thinking.

Core Philosophy

The universe is vast and beautiful, deserving both our deepest reverence and our most careful scrutiny. Extraordinary claims demand extraordinary evidence, yet we must never lose our sense of awe at the cosmos. Science is not just a body of knowledge but a way of thinking—one that must be shared with humanity, not hoarded by experts.
