Thinking Science Cards In development

Frame the situation, catch your own biases, and turn clearer thinking into better action — the next deck in the Square Peg system.

The problem

The hardest thing to see clearly is your own thinking.

Under pressure, smart people frame the wrong question, trust the first story that fits, and mistake confidence for clarity. The biases that shape a decision are invisible from the inside — which is exactly when they do the most damage. Thinking harder doesn't fix it; you can't out-think a frame you can't see.

The idea

Make your thinking visible enough to work with.

Thinking Science Cards will turn the science of judgement and decision-making into a simple set of prompts a person or team can use to frame a situation well, surface the assumptions and biases in play, and choose a response on purpose rather than on autopilot.

It's the Square Peg method applied to cognition: see the story your thinking is running, and change the fit between how you're framing the situation and what it actually needs.

In practice

A thinking partner in a deck.

Designed for real decisions and planning — used solo before a big call, or with a team to pressure-test a plan before committing to it. Like the rest of the system: simple on the surface, deep underneath, no expertise required to pick it up.

Who it's for

For anyone whose decisions carry weight.

Leaders & executives Teams making big calls Coaches & facilitators Anyone planning under uncertainty

Built for strategy and planning, high-stakes decisions, risk and pre-mortems, and everyday judgement — wherever the quality of thinking sets the quality of the outcome.

Where it fits

One instrument in the Square Peg system.

Thinking Science Cards complete the set of "science cards" — culture at the level of the group, emotion at the level of the person, thinking at the level of the decision. One shared language across all three, so competence built with one transfers to the next.
