The Three Levels of Idea Validation
Nikolaj Bomann Mertz

Thanks for your article. I think it is helpful to outline the difference between attitudinal and behavioural. Just one question:

With reference to the “two categories” you outlined: Attitudinal vs behavioural.

Is there really 3 levels of idea validation? Or only one level of validation — Behavioural: people actually doing it?

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
