QUICK ANSWERStart with the tool that matches your immediate input.
Open Brain Preference Quiz first when its stated purpose matches the result you need now. Use Sensory Preference Test only when it solves a separate next task.
This guide is for people exploring their preferences, communication, and work style. Start with Brain Preference Quiz when your immediate task is to take the Brain Preference Quiz and receive an instant, clearly explained result. Move to Sensory Preference Test only when you also need to take the Sensory Preference Test and receive an instant, clearly explained result.
The goal is not to run two tools automatically. It is to finish the first narrow task, inspect its result, and then decide whether Sensory Preference Test solves a genuinely different next step.
Both tools sit in Personality & Self-Discovery, but they handle different inputs or outcomes. Keeping those roles separate reduces repeated work and makes verification easier.
