Synthetic personas with behavioural logic

Each Mass persona is a coherent point of view, not a pile of traits. They carry age, work, location, temperament, and the habits that shape how they read a message.

Ground them in your research and current context so they are reacting to your material, not a fluent prior. We check them for internal consistency and update them with events and cultural shifts so they are not frozen in last year. Running hundreds of them is how you see where groups diverge rather than averaging them into mush.

The methodology, including validation work, is published. If a persona feels off, that is a bug, not a feature you are meant to interpret generously.
