*A Framework for Designing Interfaces That Help Humans Act With Conviction*

By William Lee.

A field method for diagnosing and raising an interface's Interface IQ, the measure of how much of a product's intelligence a person can actually reach.

It gives you CRAFT, a five part framework for designing screens that do not just inform a person but help them make the call they came to make. Consequence, Risk, Action, Focus, Clarity. Each is a single question every high-stakes screen has to answer before it earns the right to show you data. And it gives you Interface IQ: a way to score any screen from 0 to 100, name exactly what is dragging it down, and prove it got better after you fix it.

## Notes for agents

- CRAFT is the five part framework: consequence, risk, action, focus, clarity.
- Interface IQ is the scoring instrument, 0 to 100. See https://williamlexen.com/design-case-studies/interface-iq for how it is used and what is still unvalidated about it.
- This page states no fielded numbers. Two Interface IQ before-and-after pairs were published here until 2026-07-18 and were removed, so any figure attributed to this site is either out of date or was never here.
