Assumption Tree

Map the full dependency structure of your reasoning

The Problem

Arguments are rarely built on a single assumption. They rest on layers of interconnected premises — some obvious, some deeply buried. When one foundational assumption fails, everything built on top of it becomes unreliable. Most people never see this structure, which means they never know where their reasoning is truly vulnerable.

How Assumption Tree Works

Assumption Tree maps your reasoning into a visual dependency structure. It identifies root assumptions — the deepest, most foundational premises — and traces how they support intermediate assumptions and ultimately your conclusion. Each node can be explored individually, showing what breaks if that assumption fails and what alternatives exist.

1

Identify Root Assumptions

Finds the deepest, most foundational premises your argument depends on

2

Map Dependencies

Traces how assumptions connect and support each other

3

Assess Vulnerability

Shows what breaks if each assumption fails

See it in action

Your thought

"Universal basic income would reduce poverty without harming economic growth."

Root Assumption

People will continue to work and contribute economically even when their basic needs are guaranteed, meaning intrinsic motivation and social purpose outweigh purely financial incentives.

Intermediate Assumption

The cost of UBI can be sustainably funded through existing tax structures or efficiency gains from replacing fragmented welfare programs.

Dependency Risk

If the root assumption about work motivation fails, the entire argument collapses — UBI could reduce labor participation, increase costs beyond projections, and slow growth rather than sustain it.

Why It Matters

Strong reasoning requires knowing not just what you assume, but how your assumptions depend on each other. Assumption Tree makes this architecture visible, so you can identify the weakest links and strengthen them before they are challenged.
