There's a simple test for whether personality-based guidance is worth anything. Take the advice generated for one colleague. Swap in a different colleague's name. Read it again.
If it still reads fine — if nothing about it visibly breaks — then the advice was never really about either person. It was boilerplate wearing a name badge.
Why most guidance fails the swap
Type-based tools sort people into boxes, and then every occupant of a box gets the same paragraphs. Four "enthusiastic collaborators" receive four identical pages. The advice can't fail the swap test, because there's nothing individual in it to break.
The real information isn't the label. It's the intensity — how strongly a trait shows, and how it flexes with context. Consider two colleagues who'd both come out "outgoing" on any test you gave them:
- One is outgoing everywhere, at full strength, in every room.
- The other is outgoing among familiar peers — and quiet, watchful, deliberate in new or senior company.
Same label. Completely different management. The first one's silence in a meeting is a red flag; the second one's silence in an unfamiliar room is Tuesday. Advice that doesn't distinguish them will be confidently wrong about at least one.
Making it a standard, not a slogan
We score every piece of guidance our system produces against the swap test, as a formal evaluation criterion with a written rubric. Guidance scores highest only when it visibly depends on the specific person's recorded profile — their intensity, their context-flips, their recovery patterns — and scores zero when it would survive a name swap.
Personality advice that fits everyone helps no one.
It's a demanding bar. Holding an entire product to it changes what you build: you stop shipping type descriptions and start recording the things that actually differ between people who share a type. That turns out to be where all the value was hiding.
