It's behavioral marketing, vs status/aspirational marketing.

A stated preference isn't necessarily current or situational (I will choose to run instead of watching another 45 minutes of Youtube videos).

A situational preference is often inertia, and behavioral marketing will directly hinder the meta cognitive processes that usually give us the agency to override our default mode choices (John has been on YouTube for the last 20 minutes, what next suggestion is not likely to keep him there?)
