I can't take this research seriously.
> M3 Expressive designs were rated higher across desirability attributes, including “modernity,” “subculture,” and “rebelliousness.”
Subculture and rebelliousness as features of a corporate design system? What exactly were the survey questions?
> While there was a net-positive indication across all age groups, younger study participants had the most enthusiastic preference for M3 Expressive and rated the designs as high in “visual appeal” and “intention to use.”
Again compared to what, and how were the questions framed. 'Intention to use' questions are almost always leading.
In general I think the designs look pretty good, why not just let them speak for themselves instead of foisting nonsense survey results upon us.
